IMPROVEMENT IN HARNESS-SADDLE TREES.

Specification forming part of Letters Patent No. 152,192, dated June 16, 1874; application filed January 31, 1874.

'terret-nuts fastened to the backhand, in combination with the upper elevated and lower depressed bridges of the tree, instead of fastenin g them to the upper bridge or to the under bearing-plates, as they have heretofore been arranged,the objects being to enable the saddles to be made and kept in store ready for l sale without fitting on the terret-mountin gs, to

allow the purchaser to select the mountings to his taste, also to preserve the mountings better until sold by keeping them in their packages. These objects are eifected by attaching the terret-nuts to the backhand when they cannot be by any other present mode, because the nuts, being selected to fit the terret-screws wanted by the purchaser, the nuts suiting the screws can be readily fastened on the backhand, and the latter can be put in the tree to receive the terrets, whereas in all other modes the terret-nuts-cannot be satisfactorily attached after the saddle is made. It is necessary to select the nuts to fit the screws, because there are no standards of size to which manufacturers of these articles conform, so that when the nuts are built into the saddle, as heretofore, the mountings cannot be changed for want of be ing able to procure others that will fit the nuts. The invention also consists of an improved construction of the crupper-loop, whereby it can be removed at any time and another put in place without removing the filling or middle piece of leather usually placed between the seat and the frame where crupper-loop is attached.

. Figure 1 is a longitudinal sectional elevation of a harness-saddle constructed according to my invention. Fig. 2 is a section on the line :0 as of Fig. 1. Fig. 3 is a section of Fig. 1 on the line y y. Fig. 4 is aplan of the back-strap and terret-nut as arranged in the left-hand side of Fig. 1. Fig. 5 is a longitudinal sectional elevation of the back-strap as arranged in the right side of Fig. 1. Fig. 6 is a plan of a metal connecting-piece for the back-strap with a terret-nut attached to it, showing how to adapt it to my invention. Fig. 7 is a longitudinal sectional elevation of Fig. 6. Fig.8 is a front elevation, and Fig. 9 is a cross-section, on line '21 c, of a tree whereof the upper bridge, upon which my present mode of attaching the terretnuts mainly depends, is detachably connected to the tree. Fig. 10 is a plan of the under side of a portion of a saddle-tree, showing the form in which I now construct the lower bridge for the use of pad-screws for fastening the jockeys to the backhand. Fig. 11 is a plan of the tree, together with the crupper-loop and middle leather, showing the manner of connecting the crupper-loop for taking it out without removing the middle leatherr Fig. 12 is a plan of Fig. 11 without the middle leather. Fig. 13 is a section through Fig. 11, also the saddle on the line to w and Fig. 14 is a plan of the crupper-loop. Fig. 15 is a plan View, and Fig. 16 a cross-section, of a modified arrangement of the plate used to secure the terret-nut to the backhand. Fig. 17 is a plan view, and Figs. 18 and 19 are cross-sections, of another modification of said plate.

Similar letters of reference indicate corresponding parts.

Areprescnts the side portions of a tree having a middle longitudinal channel, B, for the back-strap between theflanges G, with abridge, D, passing over the channel where the terretmountings are put on, and another, E, passing under the channel at the lower end of the tree. To a tree of this kind, or any similar character, I now propose to attach the tenet-mountings and the back-straps independently of the under bearings which have heretofore been used for holding the nuts for the terret-screws, and sometimes for the pad-screws, by fastening the terret-nuts directly to the backhand and screwin g the latter up snugly against the bridge, and also attaching the pad-screw nut to the lower bridge E. F, F, and F represent the backband in different forms, to which the terretllllt'Gr is connected, the connection being varied to suit the different requirements of the back band, or as may be preferred by the constructor.

In Fig. 4, and in the left-hand side of Fig. 1, the nut being fitted in a hole in the center of the backba-nd, a re-enforcing-plate, H, of metal, is applied to the backhand to strengthen it, said band being weakened by the hole for the nut. Said plate is riveted on opposite sides of the hole by the rivets I, also by others, J', and also by the rivets K, which fasten the nut to the band. The rivets J are arranged relatively to the nut, so as to prevent itfrom being turned in the leather by the terret-serew in case it binds. The plate is also flanged at L to confine the band at the edges and prevent them from bulging, but it may be made without the flanges. Sometimes it might be best to secure the plates H to the backband before the nuts are attached. In such cases the plates will either be provided with ribs m or with a depression, n, Figs. 15 to 19, to prevent the nuts from being turned out of place by the terretscrews. The depression may be deep enough to sink the nut flush with the surface of the plate. In some cases, as when such a strap as F, in the right hand of Fig. 1 and in Fig. 5, is used, the re-enforcing-plate may be dispensed with, and when a metal strap, F Figs. 6 and 7 is used, it will be re-enforeed with leather pieces M N on the under side to make sufficient thickness for the nut, and to fit snug. The lower sunken bridge will have a hole, 5, for the padscrew nut when the backhand is connected in this way, so that the tree will be adapted for a single-pad screw. I

This invention is alike applicable to bridges cast together with the tree or made separate from it, and attached as in Figs. 8 and 9.

I now propose to fasten the crupper-loop by a screw, I), in combination with the steadyingboss 6, said screw screwing into threads formed in a hole in the tree, and I also provide holes (I, by which it may be riveted on, if preferred, or if the threads for the screws fail, as a means of connecting it calculated to be more permanent than the modes heretofore used, and offering less obstruction to the removal of the loop and putting in others in case of need. For example, when a stud is cast on the tree to be used instead of the screw, the thread formed on it is not reliable, and it makes it necessary to remove the middle leather to get the loop off, and the nut put on being clumsy and ob jectionable, whereas in this case the threads, bein g formed in the trees, are more permanent, and in case they do fail resort may always be had to the rivet-holes (1.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The tcrret-nuts attached to the backhand, in combination with the bridges and re-ent'orciug-plates, substantially as specified. I

2. The re-entbrcing-plate H, for strengthening the backhand and securing the nut, substair tially as described.

3. A jockey-tree, the lower bridge of which has a hole in the center for the pad-screw nut, substantially as described.

4. The crupper-loop secured by a screw screwin g in to the tree, in combination with the steadyingboss e, substantially as described.

5. The crupper-loop provided with the holes (1 for rivets in addition to the fastening-screw, substantially as described.

6. The removable crupper-loop secured directly to the tree by a screw, 1), substantially as described.
