TIMOTHY I. RANDALL, OF SCOFIELD, MICHIGAN, ASSIGNOR OF ONEFOURTH TO ELISHA WV. RANDALL, OF SAME PLACE.
THILL-COUPLING.
SPECIFICATION forming part of Letters Patent No. 313,528, dated March 10, 1885.
Application filed Novembcr 29, 1984.
T aZZ whom it may concern:
Be it known that I, TIMOTHY P. RANDALL,
a citizen of the United States, residing at Scofield, in the county of Monroe and State of Michigan, have invented a new and useful Improvement in Thill-Couplings, of which the following is a specification, reference being had to the accompanying drawings.
My invention relates to thill-couplings; and it has for its object to provide improved means for connecting the thill and draw irons,whereby said thill-irons may be readily removed from the draw-irons when desired.
A further object of the invention is to pro vide improved means for connecting the draw and thill irons which shall be cheap and simple in their construction, and which will hold the parts in place against accidental detachment.
\Vith these ends in view the invention consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims.
In the drawings, Figure l is a side elevation of a thill-coupling constructed in accordance with my invention. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a transverse vertical section, and Fig. 4 is a perspective View of the thill -irons detached from the draw-iron.
In the accompanying drawings,in which like letters of reference indicate corresponding parts in all the figures, A represents the drawiron, which is provided on its upper side near the forward end thereof with a dovetailed recess, a.
B represents the clip, the ends of which pass through holes or openings 0, said ends being screw-threaded. Upon the ends of the clip is mounted a flat spring-plate, O, which is held in place by nuts 0, which also secure the clip in position. The forward end of the springplate extends slightly beyond the forward end of the draw-iron, and is bent downwardly to form a finger-piece. A recess or opening, (I, is provided in the draw-iron near the forward end of the dovetailed recess or seat, and adapted to enter this recess or opening and project above the same is a lug formed upon the up- 50 per side of the spring-plate.
(N0 model.)
D represents a plate which is dovetailed in form, and which is provided with an upwardly-extending lug or ear, f, having a hole or opening and located midway between the sides of the dovetailed plate.
E represents the thill-iron, which is provided with rearwardly-extending ears or lugs g, which are adapted to fit over the lug upon the dovetailed plate. A bolt passes through the registering holes or openings of the ears or lugs and pivotally secures the thill-iron to the dovetailed plate, the bolt being held rigid in the ears of the thill-iron and turning there with. The dovetailed plate is provided on its upper side with a circular recess or depres sion, in which is located a strip of rubber, which serves as a seat for the ears or lugs on the thill-iron.
The operation is as follows: The dovetailed plate is slid into the dovetailed recess or seat of the draw-iron, and when the recess on the under side of the dovetailed plate has reached the upwardly-projecting lug of the springplate said lug will seat itself in such recess and prevent the detachment of the plate until thelug has been removed from said recess. To detach the plate the finger-piece of the spring-plate is pushed downwardlyand forces the lug from engagement with the plate, which may then be readily removed. By this means of attachment the thills of a carriage may be readily removed when so desired or found necessary. Moreover, the means of attachment are cheap, simple, and effective, and can be readily and easily applied.
Having fully described myinvention, whatI claim as new, and desire to secure by Letters Patent, is-
1. In a thill-coupling, the combinatiomwith a draw-iron, of a detachable plate carrying a j ournaled thill iron, and a spring-plate for holding said plate against accidental detachment, as set forth.
2. The combination, with a draw-iron hav-' ing a dovetailed recess, of a dovetailed plate carrying ajournaled thill-iron, and a springplate for holding the parts in position, substantially as set forth.
3. In a thill-coupling, the eombination,with a draw-iron having a dovetailed recess upon 100 its upper side, of a dovetailed plate carrying I spring-p1ate secured to the under side of the a journaled thill-iron, and a spring-plate eardraw-iron, said plate having an upwardly-prorying a lug adapted to look said draw-iron jeeting lug, as set forth. and dovetailed plate in position, as set forth. In testimony that I claim the foregoing as 15 5 4. In athill-coupling, the C0li1billLl1lOl],Wlb11 my own I have hereto affixed my signature in a draw-iron having a dovetailed recess upon presence of two Witnesses. its upper side near the forward end thereof, T and an opening eonnnunieating with said re- IIMO PHY RAB DALL" cess near the forward end thereof, of a dove- \Vitnesses:' x0 tailed plate carrying a journaled thill-iron, JOHN KILEY,
and having a recess on its under side, and a JULIUS KING.
