JAMES G. LAWLER, OF ST. CHARLES, MISSOURI.

RAILROAD-CAR.

SPECIFICATION forming part of Letters Patent No. 592,932, dated November 2, 1897.

Application filed September 11, 1896. Serial No. 605,484. (No model.)

To all whom it may concern:

Be it known that I, JAMES G. LAWLER, a citizen of the United States, residing at St. Charles, in the county'of St. Charles and State of Missouri, have invented a new and useful Improvement in Railroad-Cars, of which the following is a specification.

This invention relates to the side and end framing of a railroad-car. Under the present method of car-framing the top beams or side and end plates are mortised on the under side to receive the tenons of the vertical posts and diagonal braces and are bored for the passage of the vertical and diagonal tie-rods which connect the plates to the sills. The plates are also cut away on top to form pockets or bearings for the nuts and washers of the tie-rods. By this construction the side and end plates are considerablyreduced and weakened at the points of bearing over the body posts and braces, where the greatest strength of the plates should be maintained;

also, to remove the tie-rods for repairing the.

car portions of the roof have to be torn up or removed, which is destructive and costly in the case of metal and fibrous roofs.

My invention has for its object to secure the posts and braces and connect the tie-rods to the side and end plates without mortising or cutting away the plates and to enable the parts to be readily disconnected and removed without disturbing the roof.

The invention consists in features of novelty, as hereinafter described and claimed, reference being had to the accompanying drawings, forming part of this specification, wheron- Figure 1 is a side elevation of part of the side frame of a car constructed according to my invention; Fig. 2, a side view, to enlarged scale of a shoe attached to the side plate of the carframe and comprising my invention as applied to the door-post and its diagonal brace and vertical tie-rod, seen to the left of Fig. 1 Fig. 3, an inverted plan of the shoe; Figs. 4, 5, and 6, cross-sections through the shoe taken on lines 4 4, 5 5, and 6 6, respectively, in Fig. 2. Fig. 7 is a side view, to enlarged scale, of a modified form of the shoe attached to the side plate as applied to an ordinary side post, diagonal brace, diagonal tie-rod, and vertical tie-rod of the car-frame, as seen to the right of the door-post in Fig. 1; Figs. 8 and 9, cross-sections through the shoe on lines 8 S and 9 9 in Fig. 7. Fig. 10 is a plan of the shoe adapted for attachment to the side and end plates or corner of the car-frame; Fig. 11, a side view thereof, showing the corner-post side vertical tie-rod, and diagonal brace; and Fig. 12 an end view thereof, showing the corner-post and end diagonal tie-rod, like letters and numerals of reference denoting like parts in all the figures.

Referring to Figs. 1, 2, 3, 4, 5, and 6, arepresents a shoe which is preferably made in one piece of metalsuch as malleable iron, cast-iron, or cast-steel. The base 1 of the shoe a bears against and extends for a suitable distance along the under side of the side plate I), to which it is attached, preferably, by bolts 2, which are passed upward'through' holes 3 therefor in the body of the shoe a and through the side plate I), to which they are firmly secured by top nuts 4, the heads of the bolts 2 bearing against the under part of the shoe a. The nuts 4. are held closely in cupwashers 5, recessed into the top of the side plate 6, whereby the bolts 2 can be unscrewed from and replaced in the nuts 4 without displacing the latter or disturbing the roof of the car. on the base 1 of the shoe a are cast bosses 6, which enter corresponding recesses in the under side of the side plate I), and thereby maintain the shoe a in its proper position.

The shoe a is formed on its under side with a pocket or seating c for receiving the upper end of the door-post d and with a socket or seating e for receiving the upper end of the diagonal brace f, the said ends butting against the bottoms of the pockets or seatings c e, respectively. In the shoe a, adjacent to the door-post d and between the pockets or seatings c e, is formed, preferably, a jaw g, to which the upper end of the vertical tie-rod h is connected by a screw-bolt or joint-pin 7, passing through the sides of the jaw g and through the eye in the intermediate end 8 of the tie-rod h, as shown particularly in Fig. 5; or in lieu of a jaw 9 any other suitablyshaped lug or holder may be used and the end of the tie-rod h adapted accordingly for connection thereto.

The shoes a a for receiving the ordinary posts d and braces f, respectively, throughout the entire side frame and end frame are similar in construction and identical in prin ciple to the shoe CL and need no further description.

The shoe i for the corner-post 7t of the car-frame, Figs. 10, 11, and 12, is preferably made in one piece, having its side portion 9 at right angles to the end portion 10, the side portion 9 having the tic-rod h for the side plate I), and the end portion 10 having the tie-rod h for the end plate, (not shown,) thereby tying the side and end plates together in a substantial manner. The corner post 70 preferably tenons full size into the pocket or seating on of the shoe 2'.

By the above arrangement of shoes a a a and the tie-rods h h connected thereto no mortising or cutting away of the plates is required, and 011 tightening up the tie-rods 7L h by their nuts at the under side of the sills n the side and end plates are tightly drawn down on the posts (1 d 70 and diagonal braces f Without compressing the plates, thereby preserving their fiber and maintaining their maximum strength.

By this invention also the tie-rods, posts, and braces are easily disconnected and removed for repairs or renewal Without disturbing the roof or siding of the car, Also by this method of securing the tie-r0ds to the shoes instead of to the plates direct, the tierods can be tightened up at any time Without the danger of pulling them through the plates.

By the use of the pockets or seatings for the ends of the posts and braces the construction of the car is simplified and the cost of grooving and tenoning saved. It is further advantageous to the car-builders Whose roofs are built separately and Where there is insufficient space overhead to permit of the tierods being passed down through the top of the plates.

hat I claim as my invention, and desire to secure by Letters Patent, is

In a car-frame, the combination of a shoe attached. to the top beam or plate, and having a pocket or seating for the post-end, and brace end respectively, a tie-rod connected to the shoe and to the sill, and means for tightening the tie-rod, substantially as described and for the purpose set forth.
