SELF-'DETACHING HOLDBACK FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 546,061, dated September 10, 1895.

Application filed December 3, 1894. Serial No. 530,640. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM T. TAYLOR,

of the city of St. Louis and State of Missouri,

have invented certain new and useful Improvements in Self-Detaching I-Ioldbacks for Vehicles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to a self-detaching holdback for vehicles; and it consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

The object of myinvention is to construct a self-detaching holdback for vehicles that possesses superior advantages in point of simplicity, durability, and general efficiency.

In the drawings, Figure 1 is a top plan View of a portion of a shaft, the same having my device attached thereto. Fig. 2 is a top plan view of the shafts of a vehicle, showing my devices in position thereon; also a portion of the harness and the holdback-straps. Fig. 3 is a longitudinal sectional view on theindicated line 3 3 of Fig. 4:. Fig. 4 is a side elevation of my improved device. Fig. 5 is a top plan view of a portion of my device, showing the holdback-strap ring partially disengaged from the integral hook on the holdback.

Referring by numerals to the accompanying drawings, 1 indicates the shaft of an ordinary vehicle, upon the inside face of which and at a point about midway its length myimproved device is attached. This device comprises a rectangular metallic plate 2, the same being provided in its ends with apertures or screwholes 3, through which pass ordinary screws 4 for rigidly holding the device in its proper position. Formed integral with the face of the plate 2 and adjacent one end thereof is a hook 5, the front end of which is cut oif square and the, forward portion 6 of which lies parallel with the plate 2. Formed integral with and extending longitudinally of the plate 2 in front of the hook 5 is a tubular casing 7, in the lower side of which and near the rear end is formed a longitudinal slot 8. Mounted for longitudinal movement within this casing 7 is a bolt 9. A manipulating knob or handle 10 passes through the slot 8 in the casing 7 and is firmly screwed or seated in said bolt 9. An expansive coil-spring 11 is interposed between the rear end of the bolt 9 and the closed end of the casing 7. The action of this coilspring is to always keep the forward end of the bolt 9 in engagement With the face of the longitudinally-extending portion 6 of the hook 5. The casing 7 is so located relative the portion 6 of the hook 5 as that one half of the face of the spring-actuated bolt 9 within said casing 7 will bear and engage directly against the face-of the longitudinally-extending portion 6 of the hook 5. The other half of the face of the spring-actuated bolt 9 lies directly in front of the space formed between the plate 2 and thelongitudinally-extending portion 6 of thehook 5. r

12 indicates the rings carried by the forward end of the holdback-straps 13, said hold backstraps 13 being connected to the back straps of the harness 14 in the ordinary manner. The devices so constructed are secured to the insides of the vehicle-shafts at points usually occupied by the ends of the holdbackstraps.

When it is desired to position the rings 12 of the holdback-straps 13 in the hooks .5, the bolts 9 are moved a slight distance rearwardly by means of the handles or knobs 10, in order that said rings may be positioned between the longitudinal portions 6 of the hooks 5. The coil-springs 11 now reposition said bolts, and the rings are thus inclosed and held between the hooks 5 and the forward ends of the bolts 9. The rings 12 are thus securely held in the desired positions, and a forward pull or jerk must be given said rings sufficient to overcome the resiliency of the springs 11 before said rings 12 can be disengaged from the hooks 5. When the animal is unhitched from the vehicle, the rings are simply drawn forward until they engage directly against the endsof the bolts 9, that lie directly in the path of travel of said rings 12. A further forward movement of said rings moves the bolts 9 rearwardly and allows the rings to be disengaged from the hooks 5. This manner of detaching the rings of the holdback-straps from the holdbacks is very expeditious and labor-saving,

as there are no straps or buckles to release. Devices of this construction occupy a comparatively small space, are inexpensive, easily applied, and complete and practical in all workings and results.

What I claim is In an improved hold-back, a single integral casting 2, a hook 5 extending a distance parallel With said casting and having its front end cut off square at a right angle, a springactuated bolt 9 having its rear end cut off square at a right angle, with one-half of its forward end in close contact with the squared end of the said hook, the other half of said squared end being directly in the path of 15 end of said bolt, to positively retract the'bolt 20 without binding of the parts, as setforth.

In testimony whereof I affix my signature in presence of two Witnesse u WILLIAM T. TAYLOR. WVitnesses:
