SILL-BOLT SOCKET.

Application filed March 3, 1922. Serial No. 540,871.

To all whom it may concern:

Be it known that I, Anron J. JOHNSON, a citizen of the United States, residingat Tracy, in the county of Lyon and State of Minnesota, have invented certain new and useful Improvements in Sill-Bolt Sockets, of which the following is a specification.

The invention has reference to improvements in car construction and particularly to the under-frame fastening means for sillbolts.

An object of the invention is to provide a reinforcing and bracing member for the supporting sills of a car frame having a socket portion for receiving the sill-bolts which are thereby held against turning movement when being adjusted.

An additional object is to provide a reinforcing socket-member adapted to be incorporated into the construction of the under frame of the car and serving to substantially brace this portion from excessive strain, particularly at the draft end of the frame.

Various other objects and advantages of the invention will become apparent during the continuance of the following description.

Figure l is a plan view of a half-section of the under frame of the car showing the manner of applying the invention thereto.

Figure 2 is a side elevation thereof, including a section of the flooring.

Figure 3 is a vertical, central, longitudinal section of one of the end socket-plates, and,

Figure fl. is a similar sectional view of the center socket-plate.

As usually constructed, the under frame of a car consists of laterally spaced, longitudinally extending timbers constituting the side sills, 10. intermediate sills 11, and. two center sills 12. Connecting the Sills at each end are crossed timbers respectively constituting an end still Two draft sills '14-, are also provided at each end of the frame to support the draft-rigging such as indicated generally at 15. These draft sills come directly below and. under the center sills to which they are secured by vertical. sill -bolts lb. These bolts are usually inserted through. the center sills from the top and have their lower threaded ends engaged with adjusting nuts 1'7. Centrally arranged sill-bolts 18 are also used to hold the air brake cylinder 19 in place. This cylinder is usually located at the center of the frame and is carried by suitable bracket means 20 which, is

bolted to the under side of each center sill as shown.

In laying the car floor 21, the same is ordinarily put down over the sill-bolts and, consequently, whenever these bolts are to be tightened or broken bolts replaced, a section of the floor has to be removed and replaced with a new section after the necessary repairs or adjustments have been made. This is recpiired. frequently throughout the life of the car and necessitates a great waste of time, labor, and material. It is to overcome this faulty construction that the present invention has been devised and it embodies the incorporation into the frame construction of bracing plates serving to strengthen the sills and at the same time provide bolt-sockets which not only prevent the same from turning while being tightened but also allow the convenient removal of the same for repairs, Or otherwise, without any disturbance of the car flooring.

These plates are preferably divided into different sizes as indicated respectively in Figures 3 and 4-. In the smaller size, the plate is formed with a long and narrow block portion 22 having a base flange 23 upon which it rests. The block may be cast or otherwise formed and is hollow on the inside as shown. Adjacent each end thereof, a square recess 24 is provided to receive the head of a. sill-bolt, the shank of the bolt passing downwardly through bolt opening 25 in the bottom of the recess. The recess of each socket portion is of such depth that the top of the bolt head lies flush with, or slightly below, the upper surface of the plate.

Five of these plates are used at each end of the frame and are arranged cross-wise of the center sills 12 in relatively spaced relation. The enlarged bases 23 support the plates firmly upon the sills so that the block portions 22 are received in suitable slots or cutouts n-ovided in the car flooring. The sill-bolts 16 of the draft-rigging may then be supported. at the socket end of each plate and either adjusted or removed as may be required. without any difliculty. These plates, moreover. hold the separate sills to gether so that they cannot spread, thereby strengthening the sills and lengthening the life of the flooring around the sockets.

When adjusting the nut 17 from under the car to tighten the bolt, the latter is not only prevented from turning around in the socket but the socket itself is held. from turning under pressure of the bolt head by reason of its being integrally formed with the middle or lntermedlate portion of the plate, the opposite socket-end of which is, of,

course, held in place by the sill-bolt of the adjacent center sill. These plates, therefore, serve to reinforce the frame at the draft end and to strengthen the timbers where the strain. and possibility of distortion probably are greatest. In the larger size as indicated at 22, the plate is preferably square or rectangular and provided with at least three bolt sockets 24L on opposite sides to hold the fixed sill bolts used to fasten air brake cylinder 19 in place, the plates being arranged transversely of thecenter sills with the bolt sockets supported on the tops of the sills. The use of the reinforcing plate in two sizes enables the frame to be properly strengthened and braced at pointsalong the separate sills where the strains and stresses are of varying intensities and by having the socket portion open upwardly through the car floor, the removal of any of the sill-bolts can be conveniently effected and without a waste-of flooring or labor required to remove and replace same.

Base flanges 23 project laterally from opposite sides of the block as shown to advantage in Figures '1 and 41 of the drawings, and these flanges serve to firmly support the larger plate upon the separate sills of the car frame. The upper surface of the plate lies flush with the car flooring as illustrated and thus exposes the headed end of the bolt which may be removed as previously d scribed.

From the foregoing it is believed that the advantages and novel features of my invention will be readily understood and therefore further detailed description is deemed unnecessary.

hat is claimed is 1. In a car construction, the combination with the flooring, center sills, and sill-bolts of the underframe, of reinforcing members spanning the center sills between the latter and the flooring and having bolt-sockets opening upwardly through the flooring and supporting sill -holts exposed through the flooring for removal from the frame when required.

2. In a car construction, the combination with the car flooring, center sills and sillbolts of the underframe, of reinforcing plates disposed transversely of the sills and connected thereto by means of the said sillbolts, said plates serving to strengthen the center sills against spreading and having a portion disposed upwardly through the car flooring, said upwardly disposed portions having bolt-sockets .for receiving the heads of the said sill-bolts to prevent turning of the bolts when the latter are adjusted.

In a car construction, the combination with the car flooring, center sills below the flooring, reinforcing plate-s disposed crosswise of the sills and having their longitudi nal portions disposed upwardly through the llOOllIlg and lying flush therewith. said portions having square recesses forming bolt-sockets, and sill-bolts passing vertically through the center sills and through the said plates, the heads of the said bolts being received in the sockets of the plates whereby the 'bolts are held from turning when being adjusted.

4. In a car construction, the combination with a car frame having draft sills at a-d jacent ends, double center sills, and a flooring above the sills, of a plurality of reinforcing plates spanning the center sills at each end of the frame and above the draft sills, a single platespanning the center sills at the center of the frame, each of said sill spanning plates having socket-bearing portions extended upwardly through the flooring and lying flush therewith, and sill-bolts having their headed ends received in the sockets of the said plates and their shanks passing downwardly through the plates and center sills, and adjusting nuts engaging the shanks from below the said sills.

In testimony whereof I affix my signature.

ANTON J. JOHNSON.
