J. T. TAYLOR & J. SMITH. DRAW BAR FOR MINING CARS.
110.419.899. Patented Jan. 21, 1890.
UNITED STATES PATENT OFFICE.
JOHN T. TAYLOR AND JAMES SMITH, OFBELLEVILLE, ILLINOIS.
DRAW-BAR FOR MINING-CARS.
SPECIFICATION forming part of Letters Patent No. 419,899, dated January 21, 1890.
Application filed October 15, 1888. Serial No. 288,083. (No model.)
To all whom it may concern.-
Be it known that we, JOHN T. TAYLOR and JAMES SMITH, both on Belleville, in the county of St. Clair and State of Illinois, have invented a certain new and useful Improvement in Draft Attachments for Mining-Oars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this this specification.
N o novelty is claimed in the general con struction of the cars. The improvement applies to the means of connecting the cars together in a train, the same consisting of an eye-bar at each end of the carhaving bearing against a spring and carrying suitable coupling-links and hooks,
Figure I is a side view of a car. Fig. II is abottom view of the same. Fig. III is a detail cross-section at III III, Fig. II.
At 1 are seen the track-Wheels, one of which is preferably fast to the axle 2, and the other made to turn loose thereon.
3 are the sills, to which the axles are connected by journal-boxes 4.
5 are the end timbers, which are convex at the outer side, so that the corners 6 will not come in contact on a curved track.
7 is the body or box.
8 are longitudinal rods connecting the end timbers together.
9 are the drawrods extending through the middle of the end timbers and having free endwise movement in their bearings.
10 is a cross plate or head, through which the draw-rod passes, and to which it is fastened by a pin 11, passing through the draw rod outside the plate. The plate is made to slide freely on the two longitudinal rods 8, and has recesses 10 that receive the rods.
12 is a spiral spring surrounding the drawrod and bearing at its respective ends against the end timber 5 and the crossplate. The construction is such that the spring tends to draw the rod 9 inward until its eye 13 rests against the outer side of the end timber or against a bearing-plate 14., attached to the timber.
One of the draw-rods preferably carries a hook 15, connected to the eye by means of a link 16, while upon the other draw-rod are two links 16, with either one of which the hook 15 may be engaged.
With the use of the spring-connections between the cars, it is found that an animal can draw more cars, in a train with less strain, because the cars are started one at a time, and the momentum of each car assists in the starting of all the cars behind it. The most severe strain upon the animal is in starting the train of ears, while they may be kept moving with comparative case. It is'found in practice that an animal can draw with the same ease and with less strain about onehalf as many again cars with the spring-connection as it can with the usual unyielding connections.
\Ve claim as our invention- The combination, in a mining-car, of a drawrod sliding in the end timber, a plate on the draw-rod having recesses, longitudinal rods fitting in said recesses and on which the plate slides, and a spring surrounding the drawrod between .the plate and end timber, substantially as set forth.
