DRAFT ATTACHMENT FOR VEH|CLE S;..1
SPECIFICATION forming part of Letters Patent No. 406,755, dated July 9, 1889.
Application filed January 4, 1889. Serial No. 295,461. (No model.)
To all whom it may concern: accommodate the barB, upon which said slide Be it known that I, JOHN DxMILLER, of is also mounted, passes the balance of the Washington, in" the District of Columbia; way through the same. have invented certain new and useful lin- Upon the slide D and each end thereof is provements in Draft Attachments for Vehimounted a hook, the forward one (i' for at- 55 cles; and I do hereby declare the following tachment to the draft-chain which is attached to'be a full, clear, and exact description of to the hames, and the rear one (I for attachthe same, reference being had to the aocomment to the chain which goes over the back .panying drawings, forming a part of this of the animal to support the shafts.

It will now be seen that as the draft-hook Referring to the accompanying drawings, and back-chain hook are arranged upon the Figure 1 is a top plan view of a pair of same slide it must necessarily follow that shafts with my invention applied thereto. when the draft is brought to bear upon the Fig. 2 is a side View of one of the shackles. spring the compression will cause both hooks Fig. 3 is avertical longitudinal section.

It will also be seen that Mounted upon each of the shafts A, and the strain in starting--a loaded cart, for inrigidly secured thereto, is a bar B, one end stance--is greatly lessened. As every one 35 of which is bent down, as b, at right angles to knows, the hardest part in drawing a load-is the rest of the bar. This end is passed in starting, and my invention is designed to through the shaft and is secured beneath the lessen the strain that comes at that time as same by means of a nut or in any approved far as possible.

The animal is then started, the

"When the spring is partially 50 the slide, and a hole 19 justlarge enough to compressed, the load will begin to move and with much less strain than would be required to start the same load with any other shackle now in use.
In the modifications shown in Figs. at and 5 it will be seen that my invention can be applied to vehicles where a back-chain is not needed, and it is only necessary to lessen up the strain in starting. Consequently the hook for attachment to the back-chain is dispensed with and the hook (1 only left remaining. It, however, is found necessary that the hook d should retain an upright position, and this is done by 'making'the' bar B square in crosssection and forming the hole 6 to fit the same.
Having thus described my invention, what I claim as new is- 1. In a draft'at-tachment for vehicles, the combination, with the horizontal bar rigidly attached to the 'shaft,of the slide mounted on said bar with the draft-chain or trace-hook mounted directly thereon, and the spring interposed between said slide and the forward end of the horizontal bar through which the draft is transmitted to the shaft, substan tially as described.
2. In a draft attachment for vehicles, the combination, with the horizontal bar rigidly attached to the shaft, of the slide mounted on said bar and having the socket in the forward end, the draft-chain or trace-hook mounted on said slide, and the coil-spring within the socket through which the draft is transmitted to the shaft, substantially as described.
3. Ina draft attachment for vehicles, the combination of a slide carrying hooks for attachment to the draft chain or trace and the back-chain, said hooks having pivotally attached to them pawls for retaining the links of such chains in position, and a spring interposed between said slide and the forward end of a horizontal bar upon which all these parts are mounted, and which bar is rigidly attached to the shafts of a vehicle, substantially as described.
4. In a draft attachment for vehicles, the combination, with a slide containing asocket for the accommodation of a spiral spring, and having upon it hooks for attachment to the draft chain or trace and the back-chain, said hooks having gravit-ating pawls for retaining in position said chains, a spring interposed bet-ween said slide and the forward end of a horizontal bar, upon which all these parts are mounted, and which bar is rigidly attached to the shafts of a vehicle, of a hook for attachment to the breeching-chain, said hook mounted upon the rear depending end of said horizontal bar, substantially as described.
