SEECIFICATION forming part of Letters Patent No. 768,788, dated August 30, 1904.

Application filed May 23, 1904:. Serial No. 209,290. (No modem To all whom it may concern:

Be it known that I, FRANCIS J. Cons, of Schenectady, in the county of Schenectady and State of New York, have invented a certain 5 new and useful Improvement in Locomotive- Frame-Pedestal Ties, of which improvement the following is a specification.

My invention relates to ties or binders used for connecting the lower ends of the pedestal- 1o jaws of locomotive-engine frames; and its object is to provide a device of this class which shall be of ample strength and present large wearing-surfaces and in which wear may be readily and fully taken up as required.

I 5 The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view in elevation of a portion of a lomotive-engine frame, illustrating an application of my invention; Fig. 2, an inverted plan view, on an enlarged scale, of tho pedestal-tie detached from the frame; Fig. 8, a longitudinal central section through the same; Fig. 4c,

a transverse section on the line a a of Fig. 3;

J Figs. 5 and 6, side and face views, respectively,

of one of the wedge-blocks; and Fig. 7, a longitudinal central section through one of the washer-plates.

As constructed originally and up to a com- ,5 paratively recent date pedestal-ties were in the form of a bar which was recessed to fit tapered lugs or projections on the lower ends of the pedestal-jaws and was secured and held in position by vertical bolts. This form of tie was found to be objectionable, for the reason that when it wore loose in service it could be repaired only by being upset in a blacksmith-shop and refitted. In later constructions a cast-iron thimble was interposed be- 4 tween the jaws and held by a horizontal bolt fitted with a nut by which it was tightened in operative position. to the objection that the bearing-surfaces of the bolt-head and nut on the jaws were small and insufficient, necessitating frequent retightening. It is also very difficu'lt in heavy engines to obtain suflicient transverse see- This form was subject I tional area in the bolt, as its diameter is necessarily limited by the width of the frame.

The objections above stated are entirely oh- 5 viated by my invention, and any degree of wear may be taken up without difiiculty and without involving any change in or refitting of the tie.

In the practice of. my invention I provide a pedestal-tie 61, which to combine lightness with strength is preferably, as shown, a steel castingand which is substantially a rectangular bar having vertical openings 61 near its ends, which are of proper width and length to inclose the lower ends of the pedestal-jaws S of the frame 8 and the adjusting devices presently to be described. The tie 61 is connected adjustably to the lower ends of the pedestal-jaws by horizontal bolts 64, Which 5 pass through longitudinally-elongated holes 61 in the tie and are secured by pins or nuts.

A vertical hole 61 is formed in the tie in proper position to receive the adjusting-bolt 8 of the jaw-wedge 8, which is tightened in 7 the usual manner by a nut 8 bearing on a facev on the lower side of the tie. The shoe 8 fits in the side of the pedestal opposite the wedge 8 and is held between the top of the pedestal and the top of tie.

The bearing and clamping action of the pedestal-tie on the lower ends of the pedestal jaws is effected and maintained by wedge-blocks 62, which correspond substantially in width with the frame and fit in the vertical openings 61 of the tie between the outer faces of the pedestal-jaws and faces 61' on the outer walls of said openings, Which faces are inclined correspondingly with the adjoining faces of the bodies of the wedge- 5 blocks. Bolts 62 project centrally from the lower sides of the bodies of the wedge-blocks and are made of sufficient length to receive washer-plates or bridge-pieces 63, which abut against the bottom of the tie at each side of 9 the vertical openings, and nuts 62", which engage threads on the bolts 62 and through the washer-plates exert the necessary draft upon the wedge-blocks to clamp said blocks and the adjoining ends of the pedestal-jaws firmly within the vertical openings of the. pedestaltie.

After the Wedges have been drawn so far f that their available taper is exhausted liners thatmy invention is applicable to loeomotiveframes of any of the standard constructions 1 now in service, that its clamping action upon the pedestal-jaws can be effectively exerted under all conditions of wear for which the largest surface admissible under the conditions of width of frame is provided, and that adjustments can be fully, easily, and expeditiously efi'ected whenever required by merely tigl'itening the nuts of the wedge-block bolts. The exemption from necessity of renewal or refitting of the tie is also a substantial advantage.

I claim as my invention and desire to secure by Letters Patent 1. A locomotive-frame-pedestal tie having vertical o ruenings adjacent to its ends for the reception of pedestal-jaws and clamping devices, inclined transverse bearing-faces in said reams openings, and transverse bolt-holes for the reception of pedestal-jaW-conneeting bolts.

2. A locoinotive-frame-pedestal tie having vertical openings adjacent to its ends for the reception of pedestal-jaws and clamping devices, inclinedtransverse bearing-faces in said openings, a vertical bolt-hole adjoining one of the end openings, for the reception of a jaw wedgeadjusting bolt, and transverse boltholes for the reception of pedestal-jaw -connecting bolts.

3, The combination, with a locomotiveframe pedestal, of apedestal-tie having vertical openings adjacent to its ends inclosing the lower ends of the pedestal-jaws, wedge-blocks fitting in said openings, between the pedestaljaws and inclined faces on theopposite sides of said openings, nuts connected to threaded bolts on the wedge-blocks and bearing on the bottom of the pedestal-tie, and transverse connecting-bolts, passing through elongated holes in the pedestal-tie and through the lower ends of the pedestal-jaws.
