HOLDBACK.

SPECIFICATION forming part of Letters Patent No. 636,188, dated October 31, 1899.

Application filed J'uly 28, 1899. Serial No. 725,420. (No model.)

To all whom it may concern.:

Beit known that I, MICHAEL 1).'ScHALLER,

a citizen of the United States, residing at Lowell, in the county of Oneida and State of New York, have invented a new and useful Holdback, of which the following is a specication.

This invention relates to holdbacks, and has for its object to provide a simple and improved device which is applicable to either the upper or lower sides of the thills and has means for conveniently connecting the loops of the holdback-straps therewith and permitting of the latter being readily detached without manually operating the device.-

To these ends the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and the minor details of construction may be made within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is a perspective view of a portion of a thill having the present holdback fitted thereto. Fig. 2 is a bottom plan view of the device. Fig. 3 is avertical transverse sectional view' taken on the line w grof Fig. 2. Fig. 4 is a horizontal sectional view taken on the line y y of Fig. 3 and showing a different arrangement of spring. Fig. 5 is a top plan view of the yielding pin -or linger.

The same numerals of reference are used to indicate like and corresponding parts in each of the several figures of the drawings.

Referring to the accompanying drawings, 1 designates a flat attaching-plate having countersunk openings 2 for the reception of suitable fastenings, whereby the device may be fitted to the thills. Pendent from the outer edge of the attaching-plate isa pair of spaced lugs or shoulders 3 and 4, respectively, and also pendent from the opposite edge of the plate is a pair of bowed guard-fin gers 5, which are alined transversely with the respective shoulders 3 and 4. As best shown in Figs. 2 and 4, the shoulder 3 is beveled or inclined,

as at 6, said incline extending from the inner end of theshoulder outwardly and terminating intermediate of the ends thereof.

Extending transversely of the attachingplate and having one end pivoted between the adjacent inner ends of the shoulders 3 and 4 is a pin or finger 7. The pivoted end of this finger is enlarged into substantially circular form in cross-section, as shown at 8, and is provided with a smooth central bore or opening 9. Passing through this opening and also through the attaching-plate is a pivotbolt 10, having its head fitting against the lower side of the enlarged end of the finger and providedat its upper end with a nut 11, which engages against the upper side of the attaching-plate and detachably holds the pivoted finger to the plate. Projecting at opposite sides of the enlarged end of the pivotal finger are two lugs or stop-shoulders 12 and 13, respectively, which are adapted to engage the respective pendent shoulders 3 and 4, as best shown in Fig. 2 of the drawings. The lug 13 is provided with an outer beveled or inclined face, which engages against the inner beveled portion of the shoulder 3, while the opposite lug 12 engagesv against the outer side 0f the opposite shoulder '4, thereby limiting the movement of the finger. By reference to Fig. 5 it will be seen that the upper A side of the enlarged portion of the pivotal finger is provided with a socket or recess 14l which surrounds the central opening 9 and is provided with a pair of branch grooves 15 and 16, respectively, which communicate with the socket or recess. The groove 15 is preferably radial with respect to the socket and extends longitudinally in the upper face of the lug 13, while the other groove 16 opens outward through one side of the enlarged portion 8 and extends longitudinally of the piv otal finger. Mounted within the socket and loosely embracing the pivot-bolt 10 is a coiled spring 17, having one arm 1S fitted in the groove 16-and the opposite arm 19 projecting laterally outward across the top of the enlarged portion 8 and abutting against a' stopshoulder 20. As indicated in Figs. 2 and 3, the arm 19 has its extremity 21 bent at substantially right angles to the arm and fitted in an opening 22, formed in the attachingplate l. In Fig. 4 there has been illustrated IOO another arrangement of spring which has its -outwardly-projeeting arm 19 bearing against Ithe inner face of the pendent shoulder 4. The purpose of providing two grooves 15 and 16 is to permit of the arm 18 being fitted in either groove, so as to vary the tension of the spring.

In the operation of the device the attaching-plate is fitted to the underside of a thill 23, as best shown in Fig. 1 of the drawings, with the shoulders 3 and 4 and the guards 5 pendent from the thills. The pivotal finger 7 projects laterally across the face of the attaching-plate and is spaced a suitable distance below the latter and has its free end terminating short of the guards 5, and is, furthermore, located between the latter. By this arrangement the loop 2i of a holdback-strap may be conveniently passed between said guards and slipped upon the pivotal finger. In thus engaging the loop with the finger it is disposed in vertical relation, so as to pass between the guards, after which the loop assumes a horizontal position longitudinal with and adjacent to the under side of the thill. It will be understood that the pivotal finger is arranged to move in a forward direction; but it is held against rearward movement by the lugs 12 and 13 engaging with the respective shoulders 3 and et. Thus the finger is fixed against movement caused by the tension of the holdback-strap, but is free to swing forward, so as to automatically disengage the holdbaek therefrom, wherebyit is not necessary to manually operate the finger in unhitching the horse. The purpose of the coiled spring is to hold the tinger against aecidental movement and at the same time to permit of the finger being operated when so desired.

Having thus described the invention, what I claim is- 1. A holdback, comprising an attachingplate, having spaced shoulders provided at one edge thereof, and opposite spaced guards located at the opposite edge of the plate, and a transversely-disposed pivotal fin ger, having its pivoted end located between the`spaced shoulders, and provided with oppesitely-extending lugs engaging with the respective shoulders, substantially as shown and described.

2. A holdhack, comprising an attachingplate, having spaced shoulders provided at one edge thereof, opposite spaced guards provided upon the opposite edge of the plate, and a transversely-disposed pivotal finger, having its pivoted end located between the spaced shoulders, its free end terminating short of the guards and aliued therebetween, and 0pposite lugs engaging opposite sides of the respective spaced shoulders, substantially as shown and described.

3. A holdback, comprising an attachingplate, opposite spaced shoulders provided at one edge of the plate, a transversely-disposed pivotal finger, having one end pivoted between the shoulders and provided with opposite lugs engaging the respective shoulders, one face of the pivotal end of the finger being provided with a socket, having a groove communicating therewith, and a coiled spring located within the socket, and having one end fitted in the groove, and the opposite end extending transversely of the finger and engaging the attaching-plate, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

MICHAEL D. SCHALLER.
