Specification of Letters Patent.

Patented April 23, 1907.

Application filed January 5,1907. Scrial'No. 350,868.

T0 all whom it wty concern.-

Be it known that we, WILLIAM HUNTER EMEEIGK, a citizen of the United States, residing in Osawatomie, in the county of Miami and State of Kansas, and PETER ALQUrsT, a citizen of the United States, residing in Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Im rovement in Car-Frames, of which the fol owing is a specification.

Our invention relates to improvements in car frames, and more particularly to` .improvements in means for movably connecting draft timbers or other arts to the center sills or other members of t e car frame-work, and our present invention is an improvement upon the inventions forming the subject of our Patents Nos. 795,593 of July 25, 1905 and 819,047 and 819,048 of May 1st. 1906.

The object of our present invention, is to provide a simple, strong, eflicient and durale construction of parts and devices for removably connecting together the draft timbers and center sills of a car, or other parts or members of the car frame-work, without the use of long connecting bolts extending through the sills and draft timbers or other parts to be connected, and by means of Which such parts may be very rigidly and firmly connected together, and at the same time the one readily removed from the other.

Our invention consists in the novel construction of parts andA devices and in the novel combinations of parts and devices herein shown and described, and more particularly specified in the claims.

In the accompanying drawing forming a part of this specification, Figure 1 is a side elevation partly in vertical longitudinal section showing a portion of a car frame to which our invention is applied. Fig. 2 is a vertical longitudinal section taken on the line 2-2 of Fig. 3. Fig. 3 is a vertical cross section on line 3 3 of Fig. 2. Fig. 4 is a detail vertical section on line 4-4 of Fig. 3. Fig. 5

is a cross section online 5--5`of Fig. 4. Fig. 6 is a detail bottom view of the upper connecting plate and Fig. 7 is a detail plan view of the lower connecting plate. Figs. 6 and 7 show the meeting faces of the two connecting plates.

In the drawing, we have illustrated our invention as applied or used for removably connecting the draft timbers of a railway car to the center sills thereof without the use of long connecting bolts extending through the draft timbers and center sills so that the draftv timbers may be conveniently removed and replaced when required without interfering with the other parts of the car or its framework. a

In the drawing, A represents the center sills and B the draft timbers or other parts or frame pieces to be removably connected. A1

kis the front or end sill, A2 the buffer block, C

the draw-bar, C1 the side plates or stop castings of the draftV rigging'secure'd to the draft timbers B, C2 the draft rigging springs and C3 the followers, these parts being all of any usual or customary construction.

D and D1 are the upper and lower connecting plates, the Iormer being rigidly secured by bolts F F to the center sill, and the latter by a bolt F1 to the draft timber. Any desired number of pairs of connecting plates may be employed between each draft timber and its sill or the otherparts to be connected. The connecting plate D has on its under side at each end a circular recess d to receive the head f of the short connecting bolt F, and the lower connecting plate D1 has a central recess or depression d1 in its upper face to receive the head of the short connecting bolt F1 by which the plate D1 is connected to the draft timber. The upper connecting plate D has on its lower face a plurality of lugs d2, prefer ably four in number which enter correspond I ing recesses or mortices d3 in the lower connecting plate D1 and the lower connecting plate D1 is provided on its upper face with a plurality of lugs d4 which enter corresponding recesses or mortices d5 in the upper connecting plate D and which fit laterally between wedging or tapering transversely extending faces d and the lugs d4 have slightly Wedging or tapering transversely extending faces 17, the corresponding walls of the mortices in which they fit being also vcorrespondingly shaped, and the lugs d2 havesligh-tly Wedging or tapering longitudinal faces d8, and the interfitting lugs d4 have corresponding slightly wedging or tapering longitudinal faces d. By making the interlitting lugs and mortices with slightly tapering or wedging faces, a snug fit of the parts is secured, thus preventing any play between the plates. The

the corresponding lugs dzon the upper cony/ necting plate D. The lugs (Z2 have slightlyig 5 IOO intermeshing lugs d2 d4 on the connecting plates D Dl are furnished with bolt holes d through which extend transverse connecting bolts G having heads g and removable cotter pins g1 or other devices for holding the connecting bolts in place. Vashers g`Z bearing partly against each of the connecting plates D D1 are interposed between the bolt heads and the connecting plates D Dl and the cotter pins and the connecting plates D D1.

The upper connecting plates D are preferably furnished with longitudinal slots d at each end oneach side of the bolt head recess d to lighten the casting.

By providing one of the connecting plates as D with bolt head recesses d d at its ends,

and the other connecting plate Dl with a bolt head recess d1 at its middle, the bolt head recesses of the two plates being thus offset or staggered in respect to each other, the bolt head recesses do not come in the way of the interfitting connecting lugs d2 d4 for the connecting bolts G, and the connecting plates are thus materially simplified in construction and their strength and efficiency in operation materially improved; and by providing the connecting plates with slightly tapering or wedging faced interfitting lugs and mortices both in respect to the transverse faces, and longitudinal faces, a very strong, secure, rigid and immovable union is effected between the connecting plates and the center sills and draft timbers or other parts connected thereby, while at the same time the draft timbers are enabled to be quickly and easily removed as there are no long connecting bolts extending through both the draft timbers and center sills.

We claim l. In a car frame, the combination with the center sills and draft timbers, of connecting plates secured to the sills and draft timbers respectively, the connecting plates secured to the center sills having each bolt head recesses at each end and short bolts connecting the same to the centerv sills, the connecting plates secured to the draft timbers having each a bolt head recess at its middle and a short bolt connecting the same with the draft timbers, said connecting plates having on their meeting faces interfitting lugs and mortices and connecting bolts extending through the intermeshing lugs on the two-plates, substantially as specified.

3. In a car frame, the combination with the center sills and draft timbers, of connecting plates secured to the sills and'draft timbers respectively, the connecting plates se- ,cured to the center sills having each bolt head recesses at each end and short bolts connecting the same to the center sills, the connecting plates secured to the draft timbers having each a bolt head recess at its middle and a short bolt connecting the same with the draft timbers, said connecting plates having on their meeting faces interfitting lugs and mortices and connecting bolts extending through the intermeshing lugs on the two plates, said interlitting lugs and mortices on the two plates having tapering or wedging transversey faces and tapering or wedging longitudinal faces, substantially as specified.

5. The combination with two frame members to be removably connected together, of a pair of connecting plates secured to said members respectively, and provided on their meeting faces with two sets of interfitting lugs, and connecting bolts extending through said lugs for removably connecting said plates together, said'interfitting lugs having tapering or wedging faces, substantially as specific 6.
