Letters Patent No. 89,573, dated May 4, 1869; antedated December 8, 1868.

I IMPROVE!) EOLDBACK.

, 4, The Schedule refer-red to :in these Letters Patent and making part of the same.

To all whom 'it may conce/ru:

Be it known that we, W. GARRIsoN and CHARLES H. STEVENS, of Syracuse, in the county of Onondaga, and State of New York, have invented a new and useful Improvement in Holdback; and we do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable those skilled in the art to make Yand use the same, reference being had to the accompanying drawings forming part of this speciication, in which- Figure l is a sectional view, showing the parts detached.

Figure 2 `is a sectional View, showing the parts engaged.

Figure 3 is a top view of the thill-iron and Figure 4 is a bottom view of the same.

Figure 5 is a frontview of the hook.

Similar letters of reference indicate corresponding parts in all the figures.

The thill-iron A is fastened to the thill B by means of screws, as shown in iig. 2, and connection is made between the iron A and a hook, C, on the 'end of the breeching-strap D, in a general manner, the same as ordinarily.' l

In the elevated portion of the thill-irou is cast a T- shaped opening, E e, figs. l and 2, audit is also provided with a swinging platform, j; which is supported by being pivoted at one end to A, while the other end is supported by a spiral spring, g, iig. 2.

The hook C is formed by a flat head, having a pair of ears c c, iig. 5.

'To engage theparts, the hook O is brought into position, (shown in iig. 1,) and its head. is then introduced, through the T-shaped opening, into the thilliron A, until'the ears c have passed the curved corners k k of said thill-iron.

The hook is then thrown over into the position shown in iig. 2, and the ears c become engaged with the retaining corners k, and the shoulders m of the hook also engage with the parts n of the thill-iron, and thus the hook is secure in its connection until it is thrown over forward again, as shown in fig. l.

To'prevent the hook from being turned over into the disengaging position too easily, it is provided with a dat face, h, against which the springplatform f is pressed. But in case the whifile-tree breaks, or a like accident occurs, the hook C is thrown over as soon as a forward strain is brought upon it, and then the hook pulls out, or disengages readily, so that. the horse is freed from the carriage or vehicle.

The spring-platform causes the ears e c to engage with the retaining corners k k, and also prevents ali rattle of the parts.

The thill-iron A is made of cast malleable metal,

.and has a pair of lugs 'i t, fig. 4, east upon it in such manner that by bending them over the pivot of the swinging platform f it is thereby heldin place in a simple and cheap manner.

All the tting necessary to put the parts together after they are cast is to secure the platform f to the iron, or shell A, by bending down the lugs i i.

By these means we obtain a holdback connection which is cheap, handy, and reliable.

We do not claim a recessed thill-iron and hook, as in patent No. 36,347 but What we do claim, and desire to secure by Let-ters Paten-t, is-

'lhe swinging platform fand spring g, in combination with a flat-headed hook C h and thll-iron A, as and for the purpose herein shown and described.

W. GAR-RISON.
