SADDLETREE FOR CARTS.

Specification of Letters PatentNo.

T o all whom t may concern.' l

Be it known that I, THOMAS GLAsoo, of the city of Wilmington, in the county of New Castle and State of Delaware, have invented a new and useful Improvement in the Construction of Saddletrees for Shaft- Horses Saddles for Carts, Drays, and Wagons, and I dol declare that the following is a full and exact description.

I construct a. saddle tree with vertical lanches (A B Figures 1 and 2) to the top Or back piece forming a groove (K Figs. 1 and 2) between said flanches and open upward from the back piece, (K Figs. 1 and 2) and forming said groove. I attach Vsaid back piece at each end thereof to side plates (L and J, Fig. 1,) to rest upon the common pad on each side of the horses back bone, lengthwise of the horse, similar to the common cart, dray, and wagon shaft horse saddles, the said back piece (K Figs. 1 and 2.)v with the said flanches (A, B, Figs. 1 and 2) forming said groove (K Figs. 1 and 2, being also the bottom of said groove) I make by* preference of cast iron, and the said side plates (I and J, Fig. 1) I make by preference of wood, I construct three or more ooncave rollers (C, D, E, Figs. 1 and 2) to o`per-y ate in and revolve orosswise in said groove (K, Figs. 1 and 2,) upon journals or center pins (F, G, H, Figs. 1 and 2,) which journals or center pins I pass through the center of said rollers from the one of said anches v to the other ianch, and fasten said journals at each end thereof in the said ianches A and B, Figs. 1 and 2, so as the said roller `to secure by Letters Patent is- 5,795, dated September 19, 1848. A

will revolve freely upon the said journals or center pins, by the actionof a back chain n 1 'y provement is as follows: By the more easy Vmovement of the said back chain upon said rollers, thanin thecommon way, the shaft horse is relievedl from the usual 4side and sudden pressures, caused by the movements of the shafts-the one shaftup and the other i down in consequence of unevenness "of", the

ground over which the wheels of the car' riage are liable to pass, `and by the vibrathe horses back is relieved fromv the usual rubbing of the lsaddle when turning and when the horse by his common motion is at work.-` n i v Y What I claim as my invention and desire y The friction rollers C and VE so con-v structed as to slide on theiraxesin the manner and for the purpose described and represented. f
