MOTOR-TRUCK.

SPECIFICATION forming part of `Letters Patent No. 547,476, dated October 8, 1895.

Application tiled January 3, 1894.

To @ZZ whom t may concern.-

Be it known that we, JOHN A. BRILL and lVALTER S. ADAMS, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have made certain new and useful Improvements in Motor-Trucks, of which the following is a specification.

This invention has reference more particularly to the class of trucks that have pivotal side bearings for the car-body, and one object of the invention is to provide an improved construction of axle box frame, whereby means are provided for guiding the car-body side-bearing posts, as well as for connection with the means for drawing between the car- For this purpose the axle-box yokes are connected with bars or extensions-that lie over the side bars of the axle-box-frame side bars, and said extensions are connected by a cross bar, with which a drawing device is connected with the car-body or its sill. Said drawing device preferably consists of an equalizing-bar pivoted on said cross-bar and pivotally connected at its ends by links or bars with the car-body or a sill thereof. By this means the pivotal drawing point between the axle-box frame and car-body may be located where desired without disturbing the actual pivotal center of the truck, while the proper disposition' of the weight of the car-body to obtain a maximum traction is retained, the action of the drawing devices being positive in all positions of the parts. The cross-bar of the axle-box yokes also provides means for the suspension of the motor. With this construction, also, the weight of the car-body is borne between a pair of wheels and the pivotal center of the truck whereby the truc-k is properly held on the tracks and pounding of the wheels is avoided.

The invention further consists in the novel details of improvement and the combination of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein-- Figure 1 is a plan view of our improved truck, a portion of the carhsills being shown Serial No. 495,547. (No model.)

in position, and Fig. 2 is a partly-broken side elevation thereof.

In the accompanying drawings, in which similar numerals of reference indicate corree sponding parts in both views, the truck is shown provided with large driving-wheels l and smaller trailing wheels 2.

3 represents the axle-box-frame side bars, 4 the axle-box yokes for the driving-wheels l, and 5 the yokes for the axle-boxes of the wheels 2, the yokes 4 and 5 being connected with the side bars 3, as shown, or in any desired manner.

6 represents extensions from the yokes 4, and 7 is across-bar connecting said extensions. 8 are extensions from the yokes 5, and 9 is a cross-bar connecting said extensions 8, the parts 3, 4, 5, 6, 7, 8, and 9 together forming the axle-box frame.

As shown in Fig. 2, the lower part of the upright 4a of the yoke 4 is connected with the end of the side bar 3, and the upper part of the upright 5a of the yoke 5 is connected with the opposite end of said side bar, whereby provision is made for the difference in height of the axles la 2a of the wheels l 2. From the upper parts or tops of the yokes 4 extend bars or extensions 10, that lie over the side bars 3 and extend parallel therewith, as shown. The ends of the extensions 10 are connected by a cross-bar 11, as shown in Fig.

l, and by preference the axlebox frame, extensions l0, and crossbar ll are made :in a homogeneous piece of metal, as by forging, whereby a firm solid structure is provided. With the crossbar 1l drawing devices are connected that also connect with the car-body or one of its sills, and these devices are so organized that a direct pull will be effected between the car-body and the truck in all positions of the-latter relatively to the car-body.

`In our improvement the drawing devices extend from opposite sides of the car-body near to the truck center, and for this purpose We have provided an equalizing lever or bar 12 that is centrally pivoted by a pin 13 on the crossbar 11, said pivot lyingin the longitudinal center of the truck. (Seehigl.) Ther ends of the equalizing-lever'l2 are pivotally connected with rods or draw-bars 14 14, that at their outer ends are pivotally connected with the car-body or a cross-sill 15 thereof, preferably over or near the axle of the driving- Wheels. One end of each rod 14 is preferably forked, as at 16, to straddle the lever 12, pivot-pins 17 passing through said forks and through said lever, whereby the lever 12 and rods 14 are pivotally connected. (See Fig. 2.) The forks 16 are shown wider than the thickness of the lever 12, and the pivot-pins 17 are loosely connected with said forks, whereby freedom of movement or play is allowed between said parts to .permitup-and-down motion of the car-body relatively to the truck; but of course any desired means may be provided for this purpose.

The pivotal arrangement between the ends:

of the rods 14 and the car bodyor sill l5 may be suitably organized. Vte have shown pivots or pins 18 depending from plates 19, secured to the sill 15 by bolts 20, said pivots passing through the rods 14 and secured by pins or cotters 21. By the above construction the drawing will take place between the car-body and truck from apoint in the longitudinal center of the truck tothe sides of the car-body, through the medium of the crossbar 1l, equalizinglever 12, and rods 14, and as the truck and car move relatively to cach other the lever 12 and rods 14 will assume the necessary positions, the lever 12 suitably turning on its pivot 13 to provide for the various movements of the car and truck. NVith this device the proper and positive drawing takes place, also, during the canting or swaying of the car and truck, the looseness of the pivots allowing for such motions Without undue strain on the parts. The same looseness of connection between the pivots 18 and bars 14 can be had, if desired.

It will be apparent that a device constructed as above set forth will afford a maximum of efficiency under all conditions, and that by having the cross-bar 11 situated at a distance from the wheels, and elevated above the side bars 3 3 of the axle-box frame a large and unobstructed space is aforded for the location of a motor or the grip devices for a cablecar.

The car-body may be spring and pivotally supported on the truck or axle-box frame in any suitable or desired manner*for instance, as shown in the patent to W. S. Adams, No. 538,857, dated May 7, 1895, which is as follows: At 25 are cradles suitably supported on the side bars 3 3 of the axle-box frame adjacent to the yokes 4, which cradles are provided With the recessed lugs to receive springposts 26 26. The posts 26 also pass freely through apertures 27 in the extensions 10, whereby they are guided, and said posts are connected by a bearing 28 that engages a depending and segmental plate 29, carried by the car-body or its longitudinal side sills 30, as more fully set forth in said patent. At 3l are coiled springs surrounding the posts 26 and resting on the cradles 25, a suitable plate 32 resting on said springs and ly ing beneath the extensions 10. The posts 26 have suitable enlargements at their upper parts that rest on the plate 32, whereby the weight of the car-body is transmitted to said springs. It will be abserved that the crossbar 11 that connects the extensions 10 acts as a brace between the outer ends of said ex-V Cnsions, and thereby greatly strengthens the parts, and the lateral strain of the posts on said extensions is reduced and danger of `loen/ding or breaking of said extensions is avoided.

It will be seen that the weight of the carbody is sustained on the axle-box frame between the yokes 4 5 and close to the large driving-Wheels, whereby the weight is properly distributed on the axle-box frame and pounding of the wheels is avoided, and that the drawing devices are located at the center weight without rendering extra work.

The brake mechanism, which is not claimed herein, but which is particularly adapted for use on this class of truck, is organized as follows: 35 are standards on the cross-bars 7 9 of the axle-box frame, and from these standards depend pivoted links 36, that are pivoted to the brake-shoes 37 38, which are thus sustained in proximity to'the wheels 1 2. The brakeshoes 37 are connected bya brake beam or bar 39, and the shoes 38 are connected by a similar beam or bar 40. To the beam or bar 40 are connected levers 4l, that extend upwardly and inwardly and are connected at their upper ends by an equalizing-bar 42. This bar 42 is made segmental at its central portion 43, the segmental portion 43 of said bar being united to inwardly-inclined mem bers 44 at the outer ends of said equalizingbar. By this means the segmental portion of the bar 42 is provided for without unduly increasing the transverse width of said bar between its ends, or, in other words, a narrow bar is provided having a segmental portion. This segmental portion 43 of the bar 42 is movably connected with a draw-bar 45 (shown provided with a forked end 46 to straddle the bar 42) and a friction-roller 47 to engage said bar, whereby the draw-bar 45 may slide on the bar 42, or vice versa. The draw-bar 45 may be connected with any suitable brakeactuating devices to actuate and apply the brake-shoes to the wheels bythe drawing-bar 42 laterally. The brake- beams 39 and 40 are connected together by rods 48, that lie close to the inner sides of the wheels, and said rods 48 may be provided with turnbuckles 49 to IOO IIO

regulate the length of said rods. In order to 1 allow the rods 48 to lie as lowas possible in theiruck and at the same time have proper connection with the levers 41, said rods have a downward bend at 50 close to their point of pivotal connection 51 with the beam 40. When the bar 42 is drawn upon, the levers 41 will be turned and thus press the shoes 3S against the respective wheels, and the rods 48 will be drawn to press the shoes 37 against the wheels l.

It is apparent that the devices for connecting the car and truck together for traction can be used in a truck not provided with the particular form of frame herein described, nor :is it limited to the other peculiarities of the truck.

Having now described our invention, what we claim is l.
