LAMP SUPPORT.

Specification of Letters Patent. Patented Feb, 14:, 1922.

Application filed. June 17, 1921. Serial No. 478,385.

T 0 all whom it may concern Be it known that I, JoHN MORGAN, a citizen of the United States, residing at Iron R ver, in the county of Iron and State of Mlchigan, have invented new and useful Tmprovements in Lamp Supports, of which the following is a specification.

It is the ordinary custom, in ore mines, for the miner to attach an acetylene gas lamp to his cap. The lamp materially adds to the weight of the cap, and being arranged directly over the forehead of the miner inflicts injury that results in constant headaches. In addition to this the lamp being retained always in one position retards, rather than aids, the miner in working under certain conditions, as for instance, when it is necessary for him to assume a determined inclination or a lying position.

It is, therefore, to be considered the object of this invention to produce a means whereby any ordinary construction of acetylene lamps employed in mines and generally adaptable for arrangement on miners caps, may be supported from the walls of a mine or from the bracing timbers therefor.

It is also my object to produce a lamp holder or support for acetylene lamps used by miners which comprises a shank having one of its ends pointed and its opposite end provided with a ball or mushroom-shaped head designed to be contacted by the hand of the miner for forcing the point into the wall or a brace in the mine, said shank'having a flattened portion formed with openings to receive therethrough the holding hooks of the lamp.

A further object is to produce a holding device or support for acetylene gas lamps such as are employed in mines, that includes a pointing impinging element having an outer enlargement in the middle of a head which is concavo-convex in cross section, said element having means for engagement with a lamp for holding the latter thereon and the pointed end thereof being normally protected when the device is not in use.

The drawings illustrate a satisfactory embodiment of the improvement reduced to practice, and in the same:

Figure 1 is a perspective view showing a miners lamp supported in accordance with;

this invention,

Figure 2 is a perspective view of the improvement, and

Figure 3 is a detail sectional view through the headed end thereof.

In one of the well known types of acetylene gas lamps used by mi.ners,'the attaching hook is round in cross section and inanother type the attaching hook is in the nature of a flat strap. It will be notedas the description progresses that with my improvement either type of these lamps may be effectively supported therein.

The improvement is constructed of metal and includes a shank 1 that has apointedend 2.- The'shank, at a suitable distance inward of its end 2 is flattened and widened, as at 3, and the said widened portion is centrally provided with an elongated opening l and a round opening 5. The elongated opening is designed to receive the fiat hook of one of the lamps heretofore referred to, and the round opening to receive the hook of the other lamp.

On its widened or thickened end the shank is provided with a reduced extension 6 that passes through a central opening in a head 7. The head is round in plan, being concavo-convex in cross section. The head may be revoluble on the stud 6, but the outer end of said stud is mashed against the outer face of the head. The convexed outer surface of the head will not inflict injury to the palm of the hand of the miner when the same is forcibly brought against the said head to cause the pointedend 2 to enter either the wall of an ore mine or the bracing timbers therefor.

With my improvement the lamp may be attached in the mine at varying desired elevations and at varying positions to best suit the miner in his work.

My improvement is of an extremely simple nature, may be cheaply manufactured and marketed, and while I am aware that 1mpinging devices have been employed for holding miners lamps, and, therefore, make no broad claim to such a construction, I hold that my improvement is superior to any similar construction with which I am acquainted. Inasmuch as the particular and peculiar shape of the head thereof permits of the same being readily inserted either in wood or ore without inflicting injury to the.

operator, and also by providing the shank with a widened portion 3 and the different sized slots therein, my improvement will effectively support against wabbling either of the well known types of acetylene gas lamps commonly employed in mines.

When my improvement is not in use the pointed end thereof is inserted in a compres round head, said shank having a flattened portion which is provided with an elongated slot and a round slot therefor.

In a device for the purpose set forth,

a shank which is round in cross section and which gradually decreases in thlckness from one of its ends to 1ts opposite end to provide the latter with a point, a head swivelled on the widened end of the shank, said head comprising a member which is round in plan and concave-convex in cross section, said shank having a flattened and widened portion provided with an elongated slot and a round slot for the purpose set forth.

3. In a device for the purpose set forth, a shank having a pointed end and a cross seetionally rounded head at its opposite end,.

said shank having a flattened and widened portion provided with an elogated slot and a rounded slot, a compressible protector for the pointed, end of the shank, and flexible means suspending the protector from the shank.

JOHN MORGAN.
