lllllllllllll v 1 uoenl oz T D STATE JOHN TAYLOR, 0F TROY, NEW-Y I TRUCK COMPANY, or

I 'IICAR-TBV To all whom it may concern: v

Be it knownthat I, JOHN TAYLOR, of Troy, in the county ofRensselaer and State of New 'York, have inventedcertain new'and useful Improvements in Car-Trucks; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to car-trucks, and in particular to means for taking up-the slack or wear between the sides of the car-axle journal-boxes and the opposed faces of the jaws of the pedestals of the truck-frame; and its object is to provide vertically-adjustable weartake-up plates between the jaws and pedestals, which plates can be adjusted so as to. compensate for the wear between the journalboxes and pedestaljaws. In the preferred form of the invention the wear-take-up plates are preferably provided with double inclines or wedge surfaces on their outer faces, and the inner faces of the jaws of the pedestals are provided with similar butopposed inclines or wedge surfaces, and the plates are bolted to the inner faces of the jaws ofthe pedestals or axle-box'housings, so that by simplyloosening the bolts and slightly raising the plates they will move inward against the sides of the ournal-box and takeup or compensate for all wear or lost motion on the sides thereof, while leaving the journal-box free to move vertically in the pedestal and permitting the necessary free action of the springs by which the truck frames are supported on the journal-boxes.

down motion of the truck, caused by the action of the car-spring, produces considerable friction and wear between the journal-boxes and jaWsQSimilar actions occur when the brakes are applied,the pressure of the brakeshoes on the wheels forcing the axles hard in the opposite direction from the pressure of the brake-shoes and causing the journal-boxes to rub severely against the jaws of the pedestals. This wear in electric-car service occurs about equally on both sides of the journal- Specification of Letters- Application filed August 31,1905. Sofia 1W0- 2 '76,fi 6 4=.*'

boxes. Therefore it'is preferable to provide wedge surfaces, so that they will hold the plates accurately and positively, and as the bolts are oblique to the line of frictional contact between the journal-box and plates they are less liable to be disarranged by the rubbing action between said parts.

In the accompanying drawings I have illustrated the invention as applied to several of the principal types of electric street-railway trucks, for which use it is more particularly adapted; but I do not restrict myself to any particular kind or construction of truck or pedestal, asthe invention is applicable to many forms of railroad-trucks and can also be applied, to locomotive-trucks for adjusting the driving-wheel boxes. 1

In said drawings, Figure 1- is a detail side elevation, partly in vertical section, of an electric street-railway motor-truck equipped with Fig. 2 is n my improved wear-take-up plates. a detail transverse section on line 2 2., Fig. 1 enlarged. Fig. 3 is an inner face View, and Fig. 4 an outer face view, of one of the weartake-up plates detached. Figs. 5, 6, and 7 are detail views showing the wear-take-up plates attached to different types of truck-pedestals. Fig. 8 is a part side elevation and part section showing a slight modification of the weartake-up plates. 1 Fig. 9 is a detail elevation showing the wear-take-up plates attached to another form of trucks. Fig. 10 is a similar View, partly in section, showing 'a slight modification.

In Fig'. l the pedestal has its opposite jaws A provided with two beveled surfaces at a on their inner faces, these surfaces inclining downwardly from the top of the pedestal. Through these inclined surfaces are lateral openings a for the passage of the bolts 0,

which secure the wear-take-up plates B to the pedestals. Each wear-take-up plate has two beveled or wedge-shaped surfaces I) b on its inner faceopposed to and adapted to fit against the beveled surfaces at a onthe pedestal-jaws. The plates, moreover, are provided with side flanges 6 which lap the front and rear edges of the jaws, as shown, and prevent transverse displacement of the plates and also protect the wedge surfaces from mud and dirt. Each plate, moreover, has a vertical slot 6 in each of its wedge portions, through which slots pass the shanks of the bolts O, the heads 0 of said bolts being engaged in recesses b in the outer faces of the plates, so as to be kept from con tact with the sides of the journal-box D and also kept from rotating or turning. The bolts are secured by nuts 0 on their outer ends, which nuts are protected by recesses or openings a in the pedestal-jaws, as shown, and through which openings the nuts are readily accessible for tightening or loosening the bolts.

The journal-box D is of ordinary construction and has vertical parallel sides which fit closely but easilyagainst the opposed faces of the wear-take-up plates B B, as shown, so as to permit the pedestal to move up and down vertically relatively to the journal-box, while not having any lateral play between said plates. In trucks having pedestals like those shown in Fig. 1 the truck-frame and pedestals are supported on the journal-boxes by means of stout helical springs E, interposed between the top 3 f the journal-box and upper member of pedestal, as shown, the pedestal being recessed or .pocketed to receive the spring, as is well known.

The wear-take-up plates may have grooves I) I) in their wedge surfaces to insure a solid square fit or contact between the wedge faces of the plates and jaws.

It will be noted that the bases of the recesses I) in the wear take-up plates and the sides of the openings o against which the nuts 0 bear, are parallel with the inclined opposed facesof the wear-take-up plates and pedestaljaws and that the bolt-openings are at right angles to such surfaces, so that the square heads of the bolts and of the nuts are parallel, and it is impossible for the bolts to shift or work loose.

Fig. 5 shows the weartake-up plates B attached to the regular or ordinary pedestal A of street-railway trucks, which do not require any specific explanation, but will be readily understood by those familiar with the art. In this case the truck-springs are arranged be tween the top of the pedestal and the axle journal-box substantially as in Fig. 1.

Fig. 6 shows the same type of pedestal as in Fig. 1, with the wear-take-up plates B attached thereto; but the truck-springs F are removed from above the journal-box and are placed on double equalizing bars G, said frame.

equalizing-bars being arranged one directly outside the truck-frame and the other inside the frame and supported at their ends on the journal-box D, as shown, forming what is known asa twin or double equalizingbar truck. The construction of this truck is not claimed herein, and therefore does not require more specific description.

Fig. 7 shows the wear-take-up plates attached to the same style of pedestal as in Fig. 5; but in this case the spring H is removed from between journal-box and pedestal and is mounted on a single equalizing-bar I, that is supported on the journal-box, as shown, and this truck is commonly known as a single equalizing-bar style of truck.

Fig. 8 shows apedestal, as in Fig. 1; but in this case the wear take-up plates B are shown as fastened by but one bolt. This is an efiicient fastening; but I prefer to use double bolts.

Figs. 9 and 10 show the wear-take-up plates B applied to a solid forged frame-truck, the pedestal J being formed or wrought practically integral with the side members K-of the In this style of truck the car-body is supported on springs M, mounted on the truck-frame, and the truck-frame is supported on springs N N, mounted on wings or hangers D attached to the journal-box, as shown.

In Fig. 10 instead of forming the wedge surfaces on the inner faces of the jaws of the pedestals they are shown as formed on auxiliary pieces J which are interposed between the wear-take-up plates B and the pedestaljaws and may be secured in place by the same fastening-bolts C that retain the wear-takeup plates in position.

The various applications of the invention above described and shown in the drawings are merely indicative of its general applicability and not restrictive thereof nor intended to limit its uses.

Obviously, whether the wedge surfaces be formed on the pedestal-jaws, as in Figs. 1 to 9, or on a plate attached to said jaws, as in Fig. 10, the invention is embodied, the formation on the jaws or on a plate attached to the jaws being merely a matter of mechanical skill and preference on the part of the constructor, and therefore the broader claims are not restricted to either specific construction. The plates will of course be preferable in applying the invention to trucks or pedestals already made as more economical than attempting to cut wedge surfaces on the jaws, and in wrought pedestals the plates would be probably preferable. On cast or malleable pedestals the wedge-surfaces can be more economically formed on the jaws.

Having thus described my invention, what I claim as new is- I. In combination with a pedestal, and a journal-box; of a wear-take-up plate interposed between the side of the journal-box and tal, said plate having inclined or wedge surfaces engagingsimilar opposed surfaces on the pedestal, and a securing-bolt transfixing the plate and pedestal-jaw, substantially as described.
