RAILWAY-CAR GEAR.

SPECIFICATION forming part of Letters PatentNo. 449,643, dated March 31, 1891.

Application tiled August '7, 1890.

To all whom it may concern:

Be it known that I, JOHN M. BLONDELL, a citizen of the United States, residing at Baltimore, and State of Maryland, have invented 5 certain newand useful Improvements in Railway-Car Gear; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable thers skilled in the art to which it appertains to make and use the same.

My invention relates to what is known in the trade as railway-oar gear -*that is to say, that portion of the running-gear of a street-railway-car vehicle comprising the axle j ourn al-box, the carryin g-sprin gs, the pedestal .stay-brace, and the posts forsecuring the axle to the body of the car; and my improvement consists of certain novel parts and combination of parts, the separate features of which will be separately and specicall y pointed out inthe claims concluding this specication, in connection with lthe accompanying drawings, in Which- Figure l represents a side elevation of a railway-car gear embracing my invention. Fig. 2 is avertical longitudinal section of the same. Fig. 3 is a vertical cross-section of the same, taken on the line a ce of Fig. 2. Fig. 4 is a horizontal section taken on the line b b of Fig. 2. Fig. 5 shows one of the separate guide-irons for the journal-box guide-posts of the gear; and Fig. 6 shows the inside face of the axle-box lid to expose its removable plate, which receives the end-thrust of the axle.

The object of my invention is to producea car-gear having separate wearing parts which are adapted for adjustment to present new wearing-surfaces at the wearing-points, to reverse their relative positions to their wearing portions, and to remove and renew them when necessary, and all this at very little cost in time, labor, and material.

My invention gives the important advantage of removing the old gear as an entirety from the body of the car and of quickly replacing it by a repaired or new one, which advantage cannot be obtained in gear constructed with posts running through the sill of the car. v

c shows a portion of the pedestal stay-brace,

-by bolts passing up through th Serial No.' 361,377. (No model.)

which is secured to the car-sill in the usual manner.

bis the pedestal, and b is the metal sillplate, which has a vertical flange b2 covering the outer face of the car-sill, and is secured e plate, and also by bolts through its flan ge. At its under side this plate has screw-threaded bosses c, into which are screwed the posts d, the lower ends of which pass through the pedestal staybrace and are secured thereto by nuts .e at the under side of said stay-brace.

f is the journal-box, which, with its pedestal, is supported upon the stay-brace and secured to the car by four posts.

g are the carrying-springs mounted upon the pedestal by the posts on each side of the journal-box d, and 7L is a supplemental spring upon the journal-box, of less height than the carrying-springs, to receive the greatest load oi the car.

The vertical movement o f the car-bod y upon its springs causes the posts to move through the pedestal, and these posts, as I have provided, take the place of the usual pedestalrods, Which pass up through the earsill and permit the car-gear to be constructed as an entirety, with its posts independentof any connection with the car-body. As a means of preventing the wear of these pedestal-posts and the wear of the sides of the journal-box, I provide a removable wear part for each. For the box guide-posts such wearing part is a cylindrical sleeve i, abutting upon and between the stay-brace and the sill-plate bosses, and for the journal-box such wearing part is a separate guide-iron j, having a concave Wear-face conforming to the convex surface of the guide-sleeve, as seen in Figs. 4 and 5. This guide-iron is preferably held in place against the side of the journal-box by ribs k, so that it can be lifted out and a new one inserted. These guide-posts have heretofore been used bearing directly upon the axle-box, and both the posts and the box were rendered useless by such wear. This guide-iron is also preferably made wedge-shaped, so as to be slipped down into its seatbetween thebox-ribs.

The pedestals are formed with seats l for the rubber cushions m, which are 'provided roo with metal-sleeved seats n for the springs, while a metal cap o forms a seat for the upper cud ol the spring and a seat for the upper rubber cushion p, which is placed against the underside ot' the sill-plate. To protect the posts of these springs from wear by contact with the metal seats ot the springs, I provide the said posts with cylindrical sleeves q, which, like the guide-sleeves for the journal-'box and post, abut upon and between the screw-th readed bosses of the sill-plate and the stay-brace. These wear-sleeves of all the posts can be turned or rotated to present a new wearingsurface, and they can be turned end for end to change the location of the wearing-surface, and they can be readily and cheaply removed and replaced by new sleeves when desired, and thus avoid the expense and trouble of replacing the posts themselves. These sleeves form auxiliary posts and reenforce and strengthen the posts proper, and these sleeves form additional shoulder-bearings to these posts, and serve to strengthen, stiften, and keep the gear in rm condition, and thereby lessen the rocking movement of the parts in the direction of the thrust of the car and their consequent loosening.

The axle-box lid 9' is provided with a removable bearing-plate s at its inner side to receive the end-thrust of the axle t, and I make this plate of brass or other suitable bean ing metal and seat it in the lidby ribs to permit its renewal when worn. I provide the stay-brace with an abutment u, against which that end of the gear abuts which is opposite to the direction of the draft for the purpose of receiving and sustaining the thrust of the axle-box against the gear in line with the draft, and thereby prevent the tilting and driving back of the gear.

\Vhile I prefer to use the removable wcai= plates at the sides of: thejournal-box, yet it is obvious that the guide-posts with renewable wear-sleeves may be used in direct wearcontact with the box. It is also obvious that the box wear-plates may be used with the posts without the wear-sleevcs- I claim as my improvementl. In combination, in a railway-car gear, the axle-box, the posts CZ, the sleeves i, the

pedestal-sill, stay-brace plates b a., and the carryin g-sprin gs, the said posts havin g screwthreaded shouldered ends supporting said plates and the said sleeves forming the guide and wear bearings for the box, as shown and described.

2. In a railway-car gear, the combination, with the axle-box and the pedestahof the box guide-posts, their wear-sleeves, and the wearplates removably secured to said box.

In a railway-car gear, the combination, with the axle-box and the pedestal, of the box guide-posts and the box removable wearplates.

4. In a railway-car gear, the combination, with the axle-box, the pedestal, and its posts, of the stay`brace having an abut-ment for the pedestal.

5. In a railway-car gear, the axle-box having its lid formed with dovetail guide-ribs on its inner side, in combination with a bearingplate secured within said guide-ribs and the axle, as shown and described.

In testimony whereof I alx mysignature in presence of two witnesses.
