E. LANGILLE MACHINE FOR APPLYING AND REMOVING DRAWBARS Filed Oct.
Patented Nov. 11, 1924 ELIJAH LANGILLE, OF STELLARTON, NOVA SCOTIA, CANADA.
MACHINE FOR APPLYING AND REMOVING DRAWBARS.
Application filed October 8, 1923. Serial No. 667,425.
To all whom it may concern:
Be it known that- I, ELIJAH LANGILLE, a subject. of the King of Great Britain, and resident of Stellarton, in the Province of Nova Sootia and Dominion. of Canada, have invented certain new and useful Improvements in Machines for Applying and. Removing Drawbars, of whiclithe following is a specification.
This invention relates to improvements in machines for applying and removing drawbars, and the objects of the invention are to provide a machine of this kind that will be more easily operated, of simple construction, and adapted to be readily moved about.
With the foregoing and other objects in view the invention consists essentially in the novel construction and arrangement of parts described in the present specification and illustrated by the accompanying drawings which form part of the same and includes, in combination with a truck member, rotatably mounted castings provided with supporting means for drawbars of different sizes and means for raising or lowering said castings, and means for fixedly securing them in a predetermined position.
Referring now to the drawings in which like characters of reference indicate corresponding parts in each figure:
Figure 1 is a side elevation of an embodiment of my device.
Figure 2 is a top plan View.
Figure 3 is a plan view of one of the operating wheels showing the supporting lock and strap for the drawbar.
Figure 4 is a longitudinal section.
Figures 5 and 6 are end views.
In the drawings, A is the device as a whole comprising a truck member B suitably mounted on wheels 10 and 11, adapted to be moved about, and formed at each end with handle means 12 for lifting the truck.
Adjacent each end of the truck B are a pair of post members 13 and 14 provided with a suitable cross top-bar 15 fixedly secured to their lower ends by angle iron 16, thereby forming a suitable frame.
Between the posts 13 and 14 are vertically arranged hollow castings 17 and 18 adapted to extend from the base plate 19 in the truck to the bottom of castings 20. These castings 20 are fixedly secured by means of a key pin 21 to vertically extending screw threaded rods 22 housed one in each of the castings 17 and 18. The castings 20 are tappe'd on each side to admit lugs 23 which are adjustable to the different sizes of drawbars used by turning the lugs in or out as. required. These lugs, in addition to holding the drawbars in place, prevent the rod 22 from turning while the stock or vertical castings 17 and 18 are in operation.
25 are straps for posts 13 and 14 and are provided with brackets 27 adapted to fit the castings 17 and 18 and suitably bolted to the brackets with sufiicient clearance to allow the castings to revolve therein.
The screw-threaded rods 22 are substantially the same length as the castings 17 and 18, while the bottom of the castings is so formed as to extend through a restricted opening in the base plate, as shown in Figure 4, to provide a trench-bearing on the top of the base plate which can be fitted, if necessary, with ball bearings.
The castings 17 and 18 are threaded on the inside to engage with the screw-threaded rods22 and on the outside are provided with hand wheels 24 adapted to rotate the castings to cause the rods 22 to move upwardly or downwardly, and thus move upwardly or downwardly the drawbar supporting castings 20.
28 is a set screw for locking the castings in adjusted position.
From the foregoing, the operation of my device will be apparent, the machine being run under the drawbar to be removed, the top or drawbar supporting castings 20 are adjusted by turning the hand wheel 24 and operating the lugs 28 to receive the drawbar. The wheels 24 are then operated to lower the drawbar as required, and the machine is run out. To replace the drawbar thus removed the new drawbar is mounted on the machine with castings 20 in lowered position, and the machine is then run beneath the vehicle and the hand wheels 24 operated to raise the drawbar into position.
As many changes could be made in the i above construction and many apparently widely different embodiments of my invention, within the scope of the claims, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpretated as illustrative and not in a limiting sense What I claim as my invention is:
1. A machine for applying and removing cross straps for said standards,-screW-threaded rods in said castings adapted to engage ThGI'GWltl'I; draW'bar-supportmg castings carried by sa1d.r'ods,- and adJuStable hand wheels-for rotating' the hollow castings, whereby;in-combination With said rods; the
drawbar-s'upportingcastings are raised or loweredr y 2. In adevice of the character described and in combination Withtruck supported" 1 In witness whereof 1 A haw hm-emit means substantially as described, means; for
