Application and sum- 22,1000.- lunatic: sumo.-

Be it known that I, FRANK W. EnMUNDs,

a citizen of the United States of America,

-. that the beam of light shall .the part and a resident of West Nyack, county of Rockland, State of New York, have inventedcertain new and useful Im rovements in Signal-Lamp Brackets, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in signal lamp brackets and particularly to an improved form of signaYlamp bracket in which means is provided for adjusting the lamp carrying arm both perpendicularly and horizontally with respect to its supporting.

means.

In semaphore signals, the lamp which is carried by a signal post for signal'indication at night is disposed at some little distance to the rear of the colored glass disks carried by t the semaphore rangement of signal lampis arm and a very slight-disarthe' bracket which carries the sufficient to considerably deflect the beam of light thrown by the lamp. 1'

In order to give the best effect, it is essential trally through the disks carried by the arm as otherwise it is not. so readily discernible. Disarrangement of such bracket arms is, however, quite common. curs through the twisting or warping of the signal post when wooden osts are used and is also often occasioned y carelessness on of the attendant who caresfor the lamps. Again it often happens that they are not properly adjusted to start with, for it is quite difficult with an-ordinary stationar bracket to accurately adjust it when initially settingit in position. In my present invention, the bracket arm may be readily and quickly adjusted in position afterthe supportingelement has been secured to the post and may as readily be readjusted later should the necessity arlse.

in order that my invention may be fully understood, I will nowproceed to describe embodiments thereof such as are illustrated in the accompanying drawings and will then point out the novel features 111 claims.

In the drawings: side elevation of a signal lamp bracket embodying myinvention, showing the same securedin position upon a metal signal pole. Fig. 2 is a top view thereof withthe signal post shown in transverse section; Fig. 3 is 16 are curved convexly bracket arm: 11 is provided with a portion 12 be directed cen-i It commonly oc-- the bracket arm together Figure 1 is a view inthe bracket, the plane of section being taken s'ubstantiallyupon the line 3-3 of Fig. 1. Fig. 4 is a view in side elevation of another form of lamp bracket embodying m invention, showing same secured to a woo en post. Fig. 5 is a topv view thereof. Fig. 6 is a detail view in transverse section upon a line 6+6 of Fig. 4.

Referring first of all to the construction shown in the first threefigures, the lamp bracket will be seen to consist generally of two parts, a supporting element 10 and a bracketarm 11. The bracket arm 10 is provided with a stra 12 by means of which it is secured upon tlie strap being provided with a bolt 1-1 for clamping'it securely in position. The supporting element 10-has a forked or bifursignal post 13, the said a detail view in transverse section through cated portion at its end furthest from the" signal post.

,said forked or bifurcated fportion comprising at arms WllOSB 1111181 068 'or crowned. Thet which'is .bent :atright angles to the main part 11 thereof, the-said portion 12 being received: between the arms 15 as will be read ly understood-by reference to the drawings. A irotalibolt 17 passes throu h the arms 15 an .the portion 12, such bot serving-not only to secure the supporting element and but also serving as a pivotal center about which the arm 11 may be swung in a horizontal direct on. The openings in the arms 15 for receivin the bolt mayibe conveniently slotted as is s own at 18' so that the said arm 11 may also have movements of adjustment toward and away from the signal post. The upper arm s further provided with which are tapped into the said arm and bear at their extremities against the open face of the bracket arm portion 12. By ad usting the studs or bolts 18, the one forward and the other backward, it will be seen that the said arm 11 may tipped. thesaid tip ing being mltted by reason 0 the rocking connection between.-the1 part 12 and the arms 15 due to the convex faceshas been properly adjusted either dicula-rly; or horizontally, boltssor studs '18 may both of them be screwed tight into place, such bolts or studs then serving as lockingthe parts into their adjusted. positwo studs or bolts 18.

be perpendicularly readily p er-- 'lfin'A fter the arm 11 e pep or both, t e said a a locking means for-securely secured directly in its swin tion.- The pivotal bolt 17 may also be slackened while the adjustment is bein carried out and ti htened up after such adjustmenthas been e ected.

In Figs. 4, 5 and 6, I have shown a somewhat modified construction in that the adjustment of the locking support therein brings about movements of the lam carrying arm in a horizontal direction and an adjustment of the pivotal connection brings about such movements in a perpendicular direction. In principle, however, the construction is just the same, the construction and operation of the latter form being substantially an inversion of the former. I have also shown the bracket as secured to a wooden form of post, though it will of course be understood that elther form is equally well adapted to be employed with either the wooden or the metal post. In this construction, the, supporting element 20 is by means of bolts 21 to the the said element is rovided with an arm 23 constituting an 0 set portion, the said arm being provided with a pivotal bolt 24 which forms the ivotal support for the bracket arm 25. The olt 24 is horizontally arranged so that the arm 25 'ng movements moves about it perpendicu arly. The arm 23 is provided with a rib 26 which enga es the horizontal portion of the arm 25 an forms a rocking connection therefor. Asecond bolt 27 passes through the arm 23 and also through a slot 28 in the horizontal portion of thebracket arm 25, the said bolts 24 and 27 constituting a means for adjusting the said bracket arm 25 with respect to the rib 26 and in a horizontal direction. The bolt 24 thus constitutes not only a pivotal support for the bracket arm but also one of the adjusting bolts for adjusting it about its rockingconnection and both of the said bolts 24 and 27 constituting locking means for securin the parts together in their adjusted position post 22 and after they have been so adjusted. The rib' 26 of this construction and the crowned portions of the inner faces 16 of the construction illustrated in Figs. 1, 2 and 3 constitute in efi'ect a fulcrum upon which the bracket arm may rock. I have further provided the arm 23 with an underhanging lug29 which carries a supporting bolt 30, the said bolt adapted to be adjusted to such a position as to receive and carry the weight of the arm 25 after it has been vertically adjusted. By the employment of this supporting bolt, it becomes unnecessary to rely upon the frictional hold of the bolt 28 to prevent the arm 25 from dropping.

From the foregoin it will be seen that as a result of either of tie constructions herein, I can readily and quickly adjust a lamp carrying arm either horizontally or perpendicularly. With such a construction, there is no.

direction at right angles to necessity to attempt ;anv great accuracy in, securing the bracket as a whole to the supporting post as the lamp carrying arm maybe quickly adjusted to meet the requirements, and that at any time the parts may be readjusted to meet other conditions or to compensate for any derangement due to a twisting or warping of the post, to bending of the lamp carrying arm or other conditions such as might arise.

What I claim is: e. 1. A signal lamp bracket. comprising two.

elements, one adapted to be secured toa signal post and the other arranged to supportaslgnal lamp, said elements having co-acting faces one of to the other, formed between them, a pivotal boltsecuring the two said elements together, the axis of said boltbeing arranged at substantially right angles to the said co-acting faces, and adjusting means including another bolt for ad usting the said parts in a direction transverse with respect to their co-acting' faces, said bolt also constitutin in part a means which is crowned with respect whereby a rocking connection is for locking the parts in t eir adjusted position.

2. A signal lamp bracket comprising two elements, one adapted to be secured to a signal post and the other arranged to signal lamp, co-acting portions constituting a rocking connection, whereby relative rocking movements may be obtained between the two saidparts, and bolts upon either side of the center of such rocking connection, the relative adjustment of which is adapted to produce such rockin movements, the said bolts also serving asdocking means for securing the parts together after they have been thus adjusted, but having as to permit the said parts to have pivotal movements with respect to each other in a the direction of the said rocking movements.

3. Ina signal lamp bracket the combination with a sup be secured to a signal post, the said supporting element provided with an arm having a convex portion thereon, of a bracket arm having a plane ortion arranged to engage said convex portion and pivoted to the supporting element about an axis at right angles to the face of such convex portion, and means for maintaining the parts in the positions to which they may be adjusted.

, 4. A'signal lamp bracket comprising two elements, one adapted to be secured to a sig-' nal post and the other arran ed to supporta signal lamp, one of the sai elements pro- .vided with a crowned portion or fulcrum,

and the other with a ortion having a substantially lane face wiiich engages the same, and bolts ocated upon oppo'slte sides of the said point of engagement for adjusting the such engagement with the parts ortlng element adapted to relative position of the elements with respect to the said fulcrum, the said bolts haying such engagement with the saidelements as to perm1t the same to have a. swingin movement with respect to each other parafiel with the said plane face. 5. A signal lamp lqracketcomprising two elements, one adapted to be secured to a signal post and the other arranged to support a signal lamp, one of the said elements provided with a crowned portion or fulcrum and the other with a portion having a substnntially plane face which engages the same,
