SPRING APPLIANCE FOR HARNESS.

SPECIFICATION forming part of Letters Patent No. 457,156, dated August 4, 1891.

Application filed October 20, 1890. Serial No. 368,766. (No model.) Patented in England September 17, 1889, No. 14,622-

To all whom it may concern: I

Be it known that I, CLEMENT ARTHUR HILL, a citizen of England, residing at Sheifield, in the county of York,En gland,haveinvented certain new and useful Improvements in Spring Appliances forHarness, Road, and other Vehicles, and for other purposes, (and for which I have obtained a patent in Great Britain, No. 14,622, dated September 17, 1889;) and I do herebydeclare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a spring appliance for harness in which there is combined with two draw-rods a longitudinally-slotted frame within which they work, a spring wound on said frame and passing at one end through a slot in the latter, the said spring connecting said draw-rods and frame, and the motion of the said draw-rods in either direction being resisted by elastic connection with said frame.

In the accompanying drawings, Figure 1 represents a side elevation of the devices embodying my invention. Fig. 2 represents in detail the slotted tubular frame. Fig. 3 represents in detail the collar and draw-bar, and Fig. 4 represents a modification of Fig. 1.

A and A represent the draw-rods provided with holes and slots. These rods are also each provided at one end with an eye,hook, or swivel attachmentto receive the harness connections.

B is the tubular frame, slotted at D and D to allow spring C to pass through the rods A and A, also to allow motion of said spring. Said frame B is also provided with holes to receive the pins which secure the collars E and F upon its ends. These collars E and F are provided with holes for securing them and act as stops, against which the ends of spring 0 are compressed.

The draw-rods A and A lit within the tubular frame B and are held normally so by spring 0, which passes around frame B on its outer surface and then through slots D and D and the holes in the ends of said draw-rods. This will constitute the extension part of my device. The spring 0, after passing through the holes in rods A and A, passes out through away with these collars by turning the ends of the spring 0 in through additional slots cut in frame B and the draw-rods A and A, the outer ends of the slots inthe frame B acting as the stops, the ends of the spring C working freely in the slots in the draw-rods.

This invention may be used on any chain, rope or the like, where it is desirable to break any sudden shock or strain.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with two draw-rods and a longitudinallyslotted frame within which they work, a spring wound on said frame and passing at one end through a slot in the latter, the said spring connecting said draw-rods and frame, and the motion of the said drawrods in either direction being resisted by elastic connections with said frame, substantially as set forth. I

2. In combination with a slotted tube, a spring Wound thereon and passing at one end through a slot therein, and draw-rodsworking within said tube and having the said spring attached thereto, the arrangement of the latter being such that a part will be compressed while a part is expanded by the same motion of the draw-bars, so as to constitute, in effect, two springs of reverse action, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses. I

CLEMENT ARTHUR HILL.
