UNITED STATES PATENT OFFICE 1,944,185 'rnnNmoN Anrns'rAnLE snrron'r Edward J. hanger, reman cm. Application February 18, 1932. Serial No. 593,825 3 Claims. (on. 16-44) My invention relates to adjustableand comrest and illustrating the same as being welded pres-sible trunnion supports to be used upon furto the plate. niture, bedsteads, safes, garage doors, and the Fig. 7 is a pair of garage doors. A pair of my like. supports are shown associated therewith and The invention is comprised primarily of 2. cylshown holding the doors in full normal raised inder having one or more brackets associated position. therewith to adapt the same for being removably Like reference characters refer to like parts secured to any suiiable object to be supported. throughout the several views. A ball bearing trunnion wheel is associated with I preferably make my device of a barrel 1. The 10 the base and is adapted for being cushioned upon barrel is made of any suitable cylindrical matea compressible reacting element as a coil spring. rial as pipe. Brackets 2 and 3 are secured to the Means being associated therewith to adapt the one side of the pipe. The brackets having fascushion to meet the requirements of use. tening holes 4 and 5 in the oppositely disposed One ofvthe objects of my invention is to conends to facilitate the fastening of the assembly 15 struct a trunnion support that is of simple deto the material for holding the assembly in place sign, one that may be easily and cheaply conupon the object to be supported. I thread the structed and one that will have a long and useful upper end 6 of the barrel to facilitate the securlife. ing of a cap closure '2 thereto.
A still further object of my invention consists A trunnion caster support 8 forms the base of 20 in so constructing the device that it will have the assembly and a trunnion wheel 9 is secured to freedom to movement when in use. The assemthe trunnion wheel support and is rotatably supbly may be easily adjusted to meet the requireported upon an axle 10. A secondary barrel 11 ments of the service with which the same is to is slidably disposed within the primary barrel 1 be used. and the barrel 11 is secured to the head 12 of 25 A still further object of my invention consists the trunnion wheel assembly. Ball bearings 13 in so constructing my device that it will comprise are disposed between the base and the head. a minimum number of parts that are constructed A reacting element, as a coil spring is disposed and made from standard materials. within the primary, barrel 1. The oppositely dis- With these and incidental objects in view, the posed ends of the coil spring are secured to plate so invention consists in certain novel features of discs 15 and 16, the same are preferably welded construction and combination of parts, the essenthereto, as illustrated at 17 in Fig. 6. An adtial elements of which are set forth in the apjusting screw 18 is threadably secured to the pended claims, and a preferred form of embodicap 7.

55 upon which the coil spring is made to come to The stem 24 of the caster, or trunnion upno wardly extends through the secondary barrel 11. An opening 25 is disposed within the disc 15. The opening is threaded to permit the threaded end 26 of the stem for being threadably secured to the disc, or for being passed therethrough to permit the neck 27 of the stem being freely rotated relative to the disc 15. The cross sectional area of the stem 24 is substantially larger than the opening 25 in order that the stem may come to rest upon thedisc 15.
It will thus be seen that I have provided an assembly that is made quite largely of stock materials. The device is of simple construction, It
may be assembled within a pipe and the cushion ported is adapted for being placed and otherwise supported upon uneven surfaces.
The corners of the meeting edges of the doors being normally expected to drop down and sag, I
have illustrated in Fig. 7 a pair of my trunnion supports 29 and 30 secured to the edge of the door to adapt the same for being held in full raised position.
While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.
What I claim is:
1. In a device of the class described the combination of a primary barrel adapted to be secured to a door at the bottom thereof, a secondary barrel rotatably and slidably mounted within the primary barrel and having its lowermost end extending below the bottom end of the primary barrel, said secondary barrel having a trunnion wheel associated therewith by means of a supporting stem adjustably mounted through the top of said secondary barrel, a coil spring disposed within the primary barrel and having one of its ends bearing against the top of said secondary barrel .and its opposite end bearing against a disc slidably mounted within the primary barrel and carried by'an adjusting screw threadably mounted through a closure cap adapted to the top of said primary barrel, and a dust cap threadably mounted to the closure cap for housing the threaded stem.
2. In a device of the class described the combination of a primary barrel adapted to be secured to the outer surface of a door at the bottom thereof, a secondary barrel adjustably carrying a trunnion wheel adapted to yieldingly contact the floor below the door, a coil spring disdisc carried by an adjusting screw threadably exopen at its lower end and closed at its upper end 5 by a closure cap having an internally threaded aperture therethrough, a hollow secondary barrel closed at its upper end and slidably and rotatably mounted within the primary barrel and normally extending beyond the lowermost end thereof, an apertured and threaded disc superposed upon the upper end of the secondary barrel, a threaded stem extending downwardly through the closure cap and provided at its lowermost end with a disc, a coil spring disposed within the primary cylinder and having one of its ends bearing against said disc and its opposite end against the disc carried by said secondary cylinder, a trunnion wheel associated with said secondary cylinder by means of a supporting shaft extending upwardly through the cylinder and beyond the uppermost end thereof.
