Specification of Letters Patent.
Patented NOV. 26, 1907.
Application filed August 18. 1906. Serial No. 831.189
To all whom it may concern:
Be it known that I, WILLIAM G. PRICE, a resident of New Castle, in the county of Lawrence and State of Pennsylvania, have invented a new and useful Improvement in Truck-Frames; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to trucks, and more especially to motor trucks having a swing bolster.
One of the objects of my invention is to so construct and locate the transoms with reference to the bolster as to make the wheel base as short as ossible and provide for the insertion of the bolster hangers between the transoms and the bolster.
A further object is to provide a very rigid truck frame, one which will stand heavy shocks and collisions, and one in which the chafing or wear on the parts is reduced to a minimum.
To these ends my invention comprises the novel features hereinafter set forth and claimed.
In the accompanying drawings Figure 1 is a plan view of one side of my im roved truck; Fig. 2 is a side elevation part y in section; Fig. 3 a cross-section taken at the bolster; Fig. 4 shows plan and side views of the transom; Fig. 5 is a cross sectional view through the transoms, bolster and hanger; Fig. 6 is a section on the line 66 Fig. 2; Fig. 7 is a perspective view of the bolster hanger; and Fig. 8 a erspective view of the bolster hanger bracl et.
The numeral 2 designates the axles carrying the wheels 3, said axles being journaled in suitable journal boxes 4, in the ordinary manner; The bolster 5 illustrated is of a common type and as it forms no partof my present invention I will not describe the same in detail. This bolster is provided with the ordinary center bearing plate .6, and suitable springs 7 are employed.
In electric trucks, it is not desirable to have the wheel base too long, and the length of the wheel base is determined by the width from.
the outer edge of one transom to the outer edge of the other transom and by the space occupied by the motors between the center of the axle and the side of the transom as shown by the space marked 8. In order to make the wheel base as short as possible, it is necessary to locate the transoms as close as possible to the bolster, while at the same time it is also necessary to locate the transoms far enough away from the bolster, so that the bolster hanger and bolster hanger bracket can be inserted between the transoms and the bolster. To provide for this, I employ the transoms 9, which may be formed of angle bars of suitable dimensions. As shown in Fig. 4 the transoms are bent to form the inwardly projecting ortion 10, said projecting portion extending cm the center ine of the truck in both directions for a suitable distance, thereby bringin the transom for the greater part of its lengt closer to the bolster and increasing the distance between the transom and the axle to receive the motor. In bending this portion 10 of the transom, I obtain the portions 11 at each end of the transom, which provide corres onding recesses between the same and the b0 ster for the reception of the bolster hangers, as hereinafter set forth. The extreme ends of the transoms are bent to form the right angle portions 12, by means of which the transoms are secured by rivets 13 to the side frames 14.
The bolster hanger brackets 15, illustrated in Fig. 8 have the inwardly 16, and the outwardly pro ecting portions 17, and the end flanges 18 and 19. These brackets are secured to the side frames 14 by rivets 20 passing through the flanges 18 and side frames 14, said flan es being turned in the'opposite direction to t e bent ends 12 I of the transoms 10. Rivets 21' secure the flanges 19 of the brackets 15 to the transoms. By this construction the brackets act practically as braces and give a strong and ri id connection between the transoms and he side frames to guard against heavy shocks and collisions.
Interposed between the brackets 15 and the bolster, are the wear plates 22, secured to the brackets 15, and similar wear plates 23 secured to the bolster. I provide against the wear of the brackets from contact with the bolster.
The bolster hangers 24 are U-shape in form and pass down beneath the bolster springs 7 so as tosupport the bolster, the ends of the hangers extendin into the s aces between the bolster and t e ends 0 the transoms, and being secured by pivot ins 25 to the transoms and to the hanger brac ets bent portions In this manner 15. The bolster hangers are thus supported between the transoms and the hangers, makin a very strong form of construction.
he load on the bolster is transmitted through the hangers 24 to the transoms 9 and bolster hanger brackets 15, and thence to the side frames 14. The equalizer'bar springs 26 support the side frames 14, said spnngs'restin u on lugs 27 on the journal boxes 4, said u being secured to the equalizer bar 28 by t e bolt 29. Theside frames 1.4. transmit the load to the equalizer bar springs 26, and where very heavy loads are to be carried the side frames 14 are not sufficiently strong to transmit'the load from the transoms to the sprin s 26. I prefer to emplo therefore, the si e frame stiffener 30, w 'ch is riveted to the side frame between the transoms and bracket 15 and said side frame. This side frame stiffener may vary in thickness and width to suit the various weights to be carried.- Sometimes when very heavy loads are to be carried, it 1s necessary to use larger springs than can be placed between the equalizer bars. I have accordingly provided springs 31, which rest upon sprin seats 32 secured to the equalizer bars 28 y the bolt 33.
, In electric motor trucks there is often considerable chafing and Wearing of the metal on the journal boxes and side frames where these parts come in contact. To rovide against such wear the journal box 4 as the jaw 35 which engages or partly surrounds a U-shaped wearpiece 36, riveted to the side frame 14 b the rivets 37. When the motors are propel ing the car they push the wheels with the journal boxes 4, and equalizer bars 28 forwardly, while the frame 14 is held back by theinertia of the car. the brakes are applied to the wheels, the same action takes place except in o posite directions, which causes the journa boxes to press hard against the wear pieces 36 and as these parts have a vertical movement with reference to each other, owing to the action of thesprings 26 and 31, the surface of the journal boxes and side frame wear pieces 36, where they come in contact, have the metal worn away. To guard against this action which brings these parts into contact with each other, I provide a tie 38,
preferably a spring plate which is secured to the s ring seat 30 by the bolts 39,-which passes t ough an eye 40 in the end of the plate 38. The length of the plate 38 is such that the journal boxes 4 are held out of contact with the wear pieces 36 in direction lon itudinal of thetrack. As the plate 38 may be several inches thick and is rigidly secured by bolts at one end and is rigidly secured between the two sides of the wear piece 36 at the other end, the side frame 14 and the wear piece 36 are prevented from moving in a lateral direction across the track,
as it may move in a Likewise, when a and consequently the said wear piece and the sides of the journal box jaw 35 are practically prevented from coming in contact so as to wear away their surfaces. In this way I provide against the wear of the journal box,
vertical or lateral direction. The late 38 is preferably made of spring stee, thin, so that it will bend in a vertical direction. to allow for the oscillation of thesprings 26 and 31.
In order that the transoms shall be low enough to directly support the nose or lug of motor and also to give clearance to the car body center late 41 when the truck is swiveling around curves I bend down the central portion of the transom as clearly shown at 42 in Fig. 3. The transoms 9 are connected by the bars 43 secured by the bolts 44.

1. In a truck, the combination of side frames, a bolster, and transoms secured to the side frames and having end portions extending substantially perpendicular to the side frames and having portions intermediate said end portions projecting toward the bolster.
