WHIPPLETREE.
(No Model.)
Patented May 28, 1889.
UNITED STATES PATENT O FICE.
WVILLIAM JACKSON BLACK, OF ALVORD, TEXAS, ASSIGNOR OF TlVO-THIRDS TO JOHN BEYETT AND C. K. THOMAS, OF SAME PLACE.
WHIFFLETREE.
SPECIFICATION formingpart of Letters Patent No. 403,903, dated May 28, 1889.
Application filed May 5, 1888. Serial No- 272,918. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM JACKSON BLACK, a citizen of the United States, residing at Alvord, in the county of WVise and State of Texas, have invented new and useful Improvements in Double-Angle-Iron Singletrees and Doubletrees, of which the following is a specification.
The invention relates to double-angle-iron singletrees and doubletrees and neck-yokes.
The object of the invention is to improve and cheapen the construction of whiflietrees and to increase their strength, durability, and lightness.
The invention consists in the novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.
In the accompanying drawings, forming part of this specification, and in which like letters of reference designate corresponding parts, Figure 1 is a perspective View of the improved singletrees and doubletrees adapted to be connected to the draft-bar of a plow.
Fig. 2 is a detail perspective view of the loop of the doubletree, showing the strengtheningpiece of metal.
Referring to the accompanying drawings, A designates a doubletree con sisting of a front rod, a, made of iron or steel, and a back rod or spring, a, constructed of steel. The ends of the front rod and the back rod or spring meet at an angle, and are welded together, making the front rod, a, and the back rod or spring, a, practically integral with each other. In order to afford a connection or means for attaching the doubletree A to the draft-bar of a plow or tongue or shafts or thills of a carriage or wagon, a central loop is formed in the back rod or spring, a, intermediate of the ends. This loop a of the may be formed by taking a turn in the back rod or spring, a, and, as shown in the singletree B, the loop a may be twisted after being formed. When it is desired to employ the doubletree in connection with heavy Work, the central loop, a is provided with a strengthening-piece of metal, 0, of approximately circular ring shape, conforming to the configdoubletree A- uration of its inner sides, whereby the doubletrees may be used in drawing the heaviest loads without distorting or bending the central loop, (L
The singletrees B are attached to the doubletree A by means of a hook or similar device, D, provided with an eye or openin d, through which an end of the doubletree passes. The portions of the ends that pass through the eyes or openings (Z are smoothed off or rounded in order to construct shoulders a against which the hooks or similar devices bear, and to form a neat connection, and to keep the hooks or other similar attaching devices D on the ends of the doubletree A metal collars or washers are provided, and after these metallic collars or washers or disks are put in place on the ends of the doubletree A the ends are swaged or enlarged by beating, whereby the metallic collars or disks, and consequently the hooks or similar devices, are securely retained in place.
The singletrees B, constructed in a manner similar to the doubletrees, consist of a front rod, 1), and a back rod or spring, 1), which rods are united together by welding. A central loop, W, is formed in the back rod or spring, 1), intermediate of its ends, and in order to strengthen the central loop, b it is twisted, instead of being provided with an extra piece of metal. In order to secure the hooks D or similar means for attaching the traces to the singletrees, the ends of the singletrees B are inserted through the eyes of the hooks, and then each end is bent over upon itself to retain the hooks thereon.
From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention Will readily be understood.
It will be seen that whiffletrees constructed in accordance with this invention are exceedingly light, strong, and cheap in construction and efficient and durable in operation.
Of course I would have it understood that I do not limit myself to the precise details of construction herein shown and described, as minor changes may be made therein without departing from the spirit of my invention, and I also propose to construct neck-yokes in from slipping inward by the shoulders (0 and disks placed upon said rounded ends and retained thereon by swaging the latter, substantially as and for the purpose described.
In testimony that I claim the foregoing as 15 my oWn I have hereto affixed my signature in presence of two Witnesses.
