DRAFT-mesme FOR CARS.

SPECIFICATION forming part of Letters Patent No. 569,696, dated October 20, 1896.

Application fled March 19,1896. Serial No. 584,005. (No model.)

To @ZZ whom il: may con-cern:

Beit known that I, GEORGE L. VEISS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Draft-Rigging for Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

)Iy invention relates to that class of draftrigging for cars in which one or more springs are combined with the draw-bar in such manner as to cushion the shocks and jars and take up the strain, incident both to pulling and pushing the car, through said draw-bar.

The object of the invention is to provide novel mechanism, of this character which shall he strong, durable, and simple in construction, and in which the maximum of spring action may be attained for the purposes stated.

The invention consists in the construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a central vertical longitudinal section of my improved mechanism. Eig'. 2 is an inverted plan view thereof. Fig. is a transverse sectional view on line 3 3 of Eig. 2, and Eig. 4: is a transverse sectional view on line -L at of Fig. 2.

Referring to vthe part-s by letter, A A represent the two draft-timbers by which, pret'- erably, the draft-rigging is supported.

B B represent two halves or sections of a casing which is adapted to contain the springs and followers, hereinafter described. Each half of the easing is provided at cach end with a transverse buffer-plate h and midway between said end plates with an internal rib b'. On the upper and lower edges of each casesection are the inwardly-projecting flanges lf3 h3, which prevent the removal of the followers or springs. These two case-sections are let int-o the sides of the draft-timbers A A opposite to each other and are there secured by transverse bolts d CL.

Two follower-plates C C lie within the easing at opposite ends thereof. They are provided with stems c c', which pass through holes in the end plates h l) and are adapted to be engaged by the end of the strap D and the end of the draw-bar, respectively. Two other follower plates C2 G3 lie normally against opposite sides of the ribs h", within the casing, resting upon the lower flanges h2. A strap D embraces the casing, followerplates, and springs, and the draw-bar lies between and is secured to the front ends of said strap.

A presser-bar G lies between the two followers ()2 C3, and it is secured bythe rivet or bolt g to the two legs of the strap D. The parts of the upper and lower edges of the bar G with which the strap is in contact are out away, leaving the shoulders g g' at the sides of the strap, which prevent the bar from twisting upon the rivet y.

Two springs E E', arranged tandem with respect to each other, lie within the casing, and are somewhat compressed between the follower-plates C C2 and C3 C', respectively. These. springs, by reason of the described construction, act simultaneously and conjointly to resist the movement of the drawbar in either direction.

Supplemental springs e e may or may not be employed. Then employed, they lie within the springs E E and between the said follower-plates.

Then the draw-bar is drawn forward, the end of the strap, engaging with the stem of the follower C', moves it forward, and the bar G moves the follower C2 forward, and therebythe two springs E E' are respectively compressed between said followers and the followers C Ci, which are prevented from moving forward by their engagement with the front butter-plate I) and ribs 7)', respectively. Then the draw-bar is moved backward, the followers C and Cs are moved backward by the end of the draw-bar and the cross-bar G, respectively, the follower-plates C C2 being prevented from moving by their engagement with the rear end of plate b and ribs bi, respectively. Vhen the safety limit of coinpression in said springs has been reached in both movements, the end of the strap or end of the draw-bar, as the case may be, engages with the casing, whereby further compression of the springs is prevented.

The described mechanism is simple and strong and particularly effective for the pur- IOO pose of obtaining in both the pulling and bu'ing movement of the draw-bar the conwith, two sprin gs arranged tandem and placed between the follower-plates as' described, a

strap which embraces the bufer-plates, followers and springs, a draw-bar which lies between and is secured to the front ends of said strap, and a pressure-bar lying between the two middle follower-plates and secured to said strap, substantially as and for the purpose specied.

2. In draft-rigging for cars, the combination of a casing having end plates and internal ribs near its middle, a strap passing around said casing, anda draw-bar secured to the front end of said strap, with the two follower-plates at the ends of said casing having stems which project out through the end plates of said casing, the two followerplates which lie within the casing on opposite sides of said ribs,two springs arrangedtandem and placed between the V"follower-plates as described, and a pressure-bar extending through the casingbetween the two middle followerplates, and secured at its ends to the legs of the strap, substantially as and for the purpose specified.

3. In draft-rigging for cars, the combination ofy a casing composed of two sections, each of which has the end plates b b, the internal ribs Z9' near its middle, and the internal longitudinal flanges b2 b3 on its lower and upper edges, a strap passing around said casing, and a draw-bar secured to the Ifront end of said strap, with the two followers within the casing in contact withthe ends thereof, having stems which project out through said ends, the two follower-plates which lie be- GEORGE L.
