IMPROVEMENT m CAR-COUPLINGS.
Specification,lormin'g part of Letters Patent No. 213.914, dated April 8, 1-379; application filed September 2. 1878.
To all whom it may concern; Be it known that I, Gnoaou BUTLER, of Cincinnati, Hamilton county ()hio, have inveuted a new and useful Improvement in Draw-Bars, of which the following is a spec.
ficat-ion:
My invention relates to improvements n thosedraw-bars for rnilntny-cars which are held to their proper protruded position by a suitable spring secured .to the bed or body frame.
The dra'rw-bar consists of a housing formed in two parts, and having in its front wall ori- 'flces to receive s eeves or thimbles, said orifires being eounfcrbored to receive the flanged necks of said sleeves, which necks operate against washers at each end of thehonsing, to compress a spiral spring sliding on the draw- .bar, which extends through said housing and sleeves.
In the accompanying drawings, Figure 1 is a perspective view-of a draw-bar embodying my invention. Fig. 2 is a horizontal section of the same, a portion of the head being omitted. Figs. 3 and. 4 are, respectively, a side view of the tail-bar,' and a longitudinal section of the head separated from the housing and from each other.
A B may" represent, respectively, portions of the draft-timbers and the carry-iron of acar-body. .0 0' represent the two members of a stout castflron box, of rectangular external 'and cylindrical internal conformation.-
Tongues .0. that project from the box, occupy I jogs a in the atrat't-timbers, to which the box is further secured by through-bolts 1).
The front and back walls of the box have in their parting-line circular orifices E, counterbored at e, for thereception of correspondinglyformed sleevesor thimbles F F, which receive thetail rod or bar Ur.
A spiral spring, II, being inserted in the box between a pair of washers, I I, operates to hold the flanged necks f of the sleeves snugly ivithin the counter-bores, as clearly shown'in The rod G has a head, g, so that after said rod has been inserted in the-draw-head K said rod is securely retained therein, as seen in Fig. 2.
/ After such insertion'said i'od may be passed entirely through the spring-box, as seen in ig.2, and be retained therein by a key, K.
The substitution of a new head for a broken walhx, and the front wall, 31, of the box, in consequence of the rear extremity, z, of the head colliding with the front wall, 31,-. and hence the housing, with its spring mechanism,is less liable to derangement or fracture.
It is apparent that any st'ress upon the drawhead, whether of thrust or draft, will resultin pressing the forward or hindward thimble, as the case maybe, which, in turn, pressing on its washer, must operate to compress thc sprin g in that direction until the active and resisting forces are in equil'ibr'io.
The spring-housing maybe withdrawnfor repair or inspection by first removing the drawbar and screw-bolts, and then withdrawing the box vertical-1y from its place between the drafttimbers. After liberation, as above, the two halves of the box maybe separated, so as to fully expose the spring and other contents.
I claim as new and of my invention- The draw-bar herein described, consisting of the housing 0 (IQ-having at its front walls circular orifices eounterbored at c, sleeves or thimhles F F, having flanged necks f, fitting in said counterbores e, and operating against washersI-I at each end of a spiral spring, l l', draw-hca-d'K,carr 'ing the draw-bar G, upon which said sleeves and spring slide, and operating to press said thimbles, compress the spring, and distribute thcpressure evenly with-,
in and without the housing, substantially as set forth In testimony or which invention I hereunto set m v hand.
GEO. BUTLER.
