WILLIAM I. TAYLOR, OF DECATUR, ILLINOIS.

CAR-BRACE Application filed January 8, 1909.

Specification of Letters Patent.

Patented June l, 1909.

Serial No. 471,266,

To all whom it may concern:

Be it known that I, WILLIAM I. TAYLOR, a citizen of the United States, and resident of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Car-Braces, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to devices adapted to be placed across the interior of a freight car and taking a bearing against its side walls for the purpose of holding the contents of the car in place; its objects being to generally improve upon devices of this kind for securing an increased efficiency together with simplicity of control.

The invention consists of an extensible brace having wall-engaging shoes at its opposite ends, and means for extending the brace so as to cause its shoes to firmly grip the car walls; and it consists further in details of construction, all as hereinafter set forth and as shown in the accompanying drawings embodying` a preferred form of mechanism, and in which- Figure 1 is a detail end view of a car, partly broken away and showing the brace in position; F ig. 2 is a detail side elevation of the brace; Fig. 3 is a detail plan view thereof; and Fig. 4 is a detail longitudinal section view showing the extending mechanism.

The body of a freight car is represented at 10, its side walls being shown at 11, 12. The brace, as shown, comprises a trussed frame, designated as a whole by the numeral 13, and a frame, generally indicated by the numeral 14, slidingly mounted in connection with the frame 13, both of these frames carrying at their outer ends bars 15, 16, for engaging the side walls 11 and 12 of the car.

The frame 13 is shown as consisting of a pair of tubular rods 17, 18, to the outer ends of which the bar 15 is secured in any desired manner, their inner ends being united by a cross-head 19, preferably sleeved upon the rods and adjustably secured thereto by means of set bolts 20, 21. This frame is further strengthened by means of an intermediate cross-bar 22, uniting the two tubular rods, and a truss-rod 23 uniting the bar 15 and the cross-head 19 and bowing over a strut 24 rising from and preferably integral with the cross-bar 22. The bar 15 is preferably bowed inwardly intermediate of its ends, as shown,

thereby providing a pair of wall-engaging feet 25, 26, and clearance for the outer end of the truss-rod 23 and the nut 27 applied thereto. A jam nut 28 may run upon the rod 23 to bear upon the inner face of the arch of the bar 15.

The bar 16 is shown as of the same form as the bar 15, being bowed or arched inwardly intermediate of its ends and providing a pair of pressure feet 29, 30; and preferably the several pressure feet are provided with spurs, as 31, 32, 33, 34, for securing a more firm grip upon the side walls of the car. rIhe frame 14 comprises, in addition to the bar 16, a pair of rods 35, 36, the outer ends of which are secured to the bar by any suitable means, and the inner ends of which slide within the tubular rods 17, 18.

The extending and straining mechanism herein shown comprises a ratchet bar 37, one end of which bears against and is preferably securely fixed to the arch of the bar 16, its inner end sliding in a suitable aperture through the cross-head 19, and a rearward lateral extension 38 thereof; a hand lever 39, pivoted in a pair of lugs 40, 41, rising from the cross-head 19; a pawl 42, pivoted to the lower end of the lever 39, and cooperating with the teeth 43 formed on the upper face of the ratchet bar 37; and a set of retaining pawls, preferably three in num ber, and designated 44, 45, 46, pivotally secured to a pair of lugs 47 48, rising from the rearward extension 38 of the crosshead 19.

The pawl 42 is forced into engagement with the teeth 43 by means of a spring 49, and is provided with a grip member 50, by

means of which it may be readily raised. L

The pawls 44, 45 and 46 are slightly differentiated in length, so that but one of them is in engagement with the ratchet bar 37 at a time, thereby providing locking means for the ratchet bar, though its advance movementmay be less than the distance between its teeth. These retaining pawls may be held in engagement with the ratchet bar by any suitable means, as shown each being controlled by a leaf spring 52, 53 and 54,

attached to a web 55 uniting the lugs 47, 48. Each of these pawls is provided with a forwardly-extending arm 51, lying in the path of the lower end of the lever 39 when fully retracted, whereby these pawls are forced out of engagement with the ratchet bar to permit its recession.

ln use the brace is placed across the interior of the car in contact With the articles to be retained, the rods 17, 18, 35 and 36, and the cross-bars uniting them constituting a lateral bea-ring face for engaging such articles, the device being so positioned that the lever 39 Will swing in horizontal plane. It is longitudinally extended by swinging the upper end of the lever 39 backwardly, thereby advancing the pa'wl 42 and moving outwardly the frame 14, the retaining pawls successively falling behind the teeth upon Which they ride, the feet of the bars 15, 1G, being thus pressed against the side walls 11 and 12 with sutlicient force to sink the spurs 31, 32, 33, 34e, into the Wood thereof. The brace is of suiiicient strength, and its grip upon the Walls of the car sufficiently strong, to hold the load against displacement `by any of the usual or ordinary jars of traffic. It Kmay be instantly released by swinging the upper end of the lever 39 forwardly, thereby carrying the paWl L12 onto the upper surface of the cross-head 19, the lower end of .the lever 39 engaging the arms 51 and raising the retaining pa-wls. Usually the side walls of the car Will have been placed under sutlicient tension by the extension of the brace to cause them to spring inwardly When the retaining pa'wls are lifted, and cause the recession of the frame 14e and the disengagement of the spurs of the shoe from the Wood. If such disengagement does not automatically occur it may, of course, be easily effected by hand.

Vhile the brace is shown, and preferably as constructed comprises a pair of frames telescopically engaged and one of them being in the form of a truss, it is obvious that these details may be departed from yand the device still be within the scope of the invention.
