7 Claims. 1

This invention relates to a' radiator bench and particularly to a bench for adiustably supporting a radiator during construction or repair work thereon. v

In the construction, maintenance and repair of radiators it is frequently desired to support the radiator in various different positions as well as to immerse it in a tank of water or other liquid for testing for leaks, or for other purposes.

Radiators are quite heavy and awkward to handle so it is almost impossible for repairmen to properly position and maintain the radiator in position during testing and repair purposes.

The present invention provides a supporting bench on which a radiator may be placed and elevated or lowered or otherwise adjusted to various positions so that the. repairman or constructor may work with ease at the various portions of the radiator as well as lower it in a tank of testing fluid or for any other reason he may wish to elevate or lower the device.

The present invention is accomplished by means of a stand having a base with an elevator screw and guide rails adjacent the screw, with a motor for driving a housing along the screw while the weight of the housing is supported by the guide rails and an elevator platform mounted on the housing and adjustable with respect thereto.

It is accordingly an object of this invention to provide a radiator repair stand.

It is a further object of this invention to provide a bench for supporting a radiator in Y any desired position.

It is a still further object of this invention to provide a bench which may be elevated to any desired position or adjusted to any desired an-- ular relation thereto.

Other objects and mam of the attendant advantages of this invention will be apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: g

Figure 1 is a side elevation of the elevator n Figure 2 is a cross section, taken substantially on the plane indicated by the line 22 of Fig ure 3 and showing the for the platform; v

Figure 3 is a front elevation'of the radiator bench:

Figure 4 is an enlarged sectional elevation of the drive screw connection and taken substantially on the plane indicatedby the line 4--4 of Figure 2;

guide support mechanism Figure 5 is an enlarged cross section taken substantially on the plane indicated by the line 5--5 of Figure 1 and showing the. bracing and locking mechanism therefor; and,

Figure 6 is a longitudinal section of the platform adjusting means taken substantially on the plane indicated by the line 6-4 of Figure 1.

According to the exemplary embodiment of the invention, the bench comprisesa base In having side members 82 and 4 preferably constructed of channel members The base ID has channel members I 2 and arranged in A-formation with a cross brace i6 and, laterally extending portions having a cross brace 18. The converging portions of the side members [4 and I2 are joined together by a means of ahead plate 22. Preferably casters 24 are placed on the base l0 so that the base may be readily moved about.

Guide rails 26' and 2-8 are mounted on the base Ill and preferably are connected to the head plate 22. Guide rails 26 and 2d extend parallel to each and terminate in a cap plate 30, a drive screw 32 has a thrust bearing 34 in the head plate 22 and extends parallel to the guide rails 26 and 28 and has a guide bearing 35 in the top plate 30. The drive screw 32 is threaded throughout substantially its length except for the lower portion on which a sheave 38 is rigidly fixed. An upstanding bracket 40 on the base member [4 supports a driving motor 42 which has a drive sheave 44 over which a belt 48 is entrained connecting the sheaves 38 and 44.

A carrier housing 50 is mounted on the drive screw 32 and has threaded connections 52 and 54 at each endthereof. A motor 42 through the drive connection turns the screw in either direction so that the housing 50 may be driven in either direction along the drive screw 32.

The carrier housing 50 is provided intermediate its length with a pair of upstanding collars 5B and 58 providing an annular seat 60 about the housing. A split collar 82 is mounted on a seat and is provided with a clamping screw 64 for locking the collar 62 with respect to the housing '50. A brace 'member .66 is rigidly connected to the collar 62 and hasextending arms 58 and it I having the ends thereof providedwith adjusting screws 12 and 14. The screws 12 and 14 being adjustably secured in apertures in the 'endsof the arms 58 and Hi and locked thereto by means of lock nuts and 18. The screws 12 and It terminate in roller bearings 88 and 82 which are in contact with the inner surfaces of the guide rails 28 and 28 respectively. 1

'An and 84 is rigidly mounted on the housing n and extends laterally therefrom. The split collar 86 is mounted on the end of the arm 84 and is provided with a clamp screw 88 by which the collar 86 may be clamped on a supporting shaft 90. The shaft 90 can be adjusted either angularly or longitudinally in the collar 86 by opening the clamp screw 88. A radiator supporting platform 92 is rigidly supported on the lower end of the shaft 98 and includes a pair of side rails 94 and-96 in which are slidably supported extension frame members 98 and I00, which can be locked in adjusted position by means of set screws I82.

In the operation of the device according to the invention the radiator to be inspected, repaired or otherwise treated, will be mounted on the platform 92 and the platform will be adjusted to any desired position by means of the pair of adjusting clamps 62 and 86. The platform can be adjusted to any desired angular relation with respect to the collar 86 and also the shaft 98 may be longitudinally adjusted as is desired through the collar 86. Likewise the housing 58 may be adjusted to any desired angular relation by means of the split collar 62 and theclamp screw 64. The reversible motor 42 will drive thecarriage 58 in any desired direction along the screw 32 and the weight of the carriageand the radiator thereon will be carried by the brace member 86 through the contacts with the guide members 2B and 28. The entire bench can be moved about as desired by means of the castors 24.

It will thus be seen that thepresent invention provides a bench which is readily adjustable to any desired positionandfor any desired operation on a radiator and-which may be readily moved about as desiredby the workman.

While the exemplary embodiment of the .invention has been shown and described according to the best present understanding thereof.

It will beapparent, to those skilled in the art, that many changes and modifications can be made herein without departing from the true spirit of the invention. 7
