T0 aZZ whom it may concern:

Beit knoWn that I, EDGAR PEOKHAM, a citizen of the United States,and a resident of New York, in the eounty of New York and State of New York, have invented eertain new and useful Improvements in Oar-Tru'oks, of whioh the following .is a speoifieation.

This invention has referenoe to eantrueks and partioularly to such trueks as are employed for street-oars.

The objeot of the invention is to simplify the oonstruotion of the truck-frame by redueing the numloer of parts of whioh the sides of such fra1nes are ordinarily composed.

A further objeot is to inorease the strength of the side frames without inoreasing the weight of the struoture, and to provide such side frames With means for aooommodating at given points springs of different types, made use of for neutralizing shoeks imparted to the Wheels and body of the oar, and for preventing the car from teetering or osoillating when in motion.

A truek-frame oonstruoted aoeordin g to 1ny present invention Will require less labor and expense in its produotion, will be less liable to beoomederanged in serviee, and the parts composing it may be more quiokly assembled than is the oase with truoks as generall y oonstrueted.

My invention is hereinafter desoribed in eonneotion with the aocompanying drawings, and in elaims at t]ie end hereof the features of novelty have been speoified.

In the drawings, Wherein like parts are indieated loy like numerals of referenoe in the several Views, Figure 1 is a side elevation of a truok embodying 1ny improvements. Fig. 2 is a side elevation of one end of the truokframe equipped with a spiral spring at the extreme end instead of with an elliptioal spring, as shown in Fig. l. Fig. 3 is a vertioal longitudinal seotion through the integrally-formed endportion of the truek-frame. Fig. 4 is a ground plan of the complete end struoture s hown in Fig. 3. Fig. 5 is a side elevation, and Fig. 6 a oentral vertieal section, of a bushing Whioh I employ in oombination With the rods whioh serve to conneet the upper ohord o1 sill of the truok With the longitudinal beam extending aeross the bottoms of the yokes of the frame. Fig. 7 is a stitution of the elliptieal spring at the end of the truok-frame, as shown in Fig. 2.

Referring to the drawings, 11 indioates the longitudinal side beams oonneoting together the end portions of the side frames, whioh inolude the yoke struotures adapted to engage with the axle-boxes 12 in the usualmanner. The longitudinal beams 11 are duplex, as shown in Fig. 2, and are riveted to the end struotures of the fra1ue, as at 13. The upper ohord 'or sill of the fra1ne is indicated by 14, and 15 is a flat beam extending longitudinally beneath the two yoke struetures and hold in place by the bolts 16 passing through the V81- tical memloers of the yoke struotures and oonneoting at the top With the sill er ohord 14.

Eaoh end portion of the fra1ne oonstitutes a single ca)sting, as shown best in Figs. 3 and 4, and oomprises the yoke struoture 17, having the flange 01 extension 18, to Whioh the longitudinal bean1 11 is adapted to be riveted, and the end extension 19 eonsisting of the horizontal member 20 and the under truss 21, whioh parts are preferably made duplex. The yoke strueture 17 of the end portions of the frame is novel in oonfiguration, as will be seen fro1n Fig. et. lt oomprises an upper horizontal memloer 22, whioh is adapted ro rest upon the aXle-loox 12, and in its under surfaoe it is provided With a reeess orsooket 23 adapted to reoeive an elastie eushion o1 spring to oo-operate With the top of the axle-box. 'lhe horizontal me1nloer 22 is preferaloly of approximately oiroular ground plan, as shown in Fig. 4. The vertioal members 24 of the yoke strueture whioh are adapted to extend downward along the sides of the axle-box are made hollow to pernuit 0f the passage therethrough of the bolts 16, whioh pass through the upper ohord, 14, and lower longitudinal beam, 15. The vertioal 1nembers 24 are also of oircular ground plan, as seen in Fig. 4. 'lhe fiange 18 forming a part of this integral end portion of the fra1ne is provided with a perfora-ted seat 25 to reoeive the spiral spring 26 and IOO longitudinal side hean1 ll.is seeured to said end portion of the frame. The end extension 19 at the fron t of the yoke strnetnre comprises the horizontal part 20 and the under trnss part 21, as stated, the said end extension being sl1own divi led longitudinally, exeept where the perforated seat 28 is located, the said seat being adapted to reeeive a spiral spring, as 29, snrrounding a holt 30, whieh passes throngh the sill 14 and through the perforated seat 28and also throngh the soeket 31 for1ned in the nnder trnss 1ne1nber 21 of said end extension. 'll1e sooket 31 is adapted t0 reeeive a connter-spring 32 for the spring 29, tl1e said Connter-spring snrrounding the lower end of holt 30, whieh latter extends tlirongh the botto1n longitudinal hea1n, 15, and its end provided Witl1 a nnt, as shown. \Vashers 33 are plaeed between the sill 14 and tl1e npper ends 0f spiral springs 29 and 2G, and also hetween tl1e lower longitudinal bean1, 15, and eonntersprings 32, as indieated. At t-he extreme outer end of tl1e extension 19 there is provided a soeket 31 for reoeiring a spiral munter-spring 30 for tl1e spiral spring 35 when such a type of spring is 1nade use 0f at that point in lieu 01": an elliptical spring. In the upper ends 0f the vertical 1nen1herS 21 0f the yoke strnotnres aro the re1novable bnshings 37, whieh are preferably made of cast-steel. These hushings are 1nade nse of for the pnrpose of gnardin g against the Wear in g of holts 16 npon tl1e yoke in the longitudinal and lateral movements lhat may bo i1n parted 170 the car-hody and through the sa1ne 110 said bolts 10. The bnshings 37 are hold in plaee by serews 37, easily removahle.

In Fig. 1 the extreme end of the truekfra1ne is equipped with an elliptieal spring 38, as shown, whieh is interposed between the end extension 19 and the sill or ohord 14. \Vhen an elliptieal spring is t0 be nsed in this position the soeket- 39 (shown in Figs. 7 and S) is made nse of, the said spring being olamped within tl1e opening i0 of said soeket, the upper part 0f the socket heilig in two seetions, whiel1 are held together by tl1e bolts and nnts 4:0 and 10, as shown in Figs. 7 and 8. That portion of the soeket 39 1narked 41 is adapted to enter the longitndinally-divided parts of t-l1e horizontal extension 20 0f tl1e end easting and to be seeured therein by rivets 42, the part41 of the Socket heing for1ned With rivet-holes 4:3, as shown.

In Fig. 2 a spiral spring 35 is snbstitnted f0r tl1e elliptieal spring 38, and in this ease the soeket 39 (shown in Figs. 9 and 10) is 1nade nse of, the same being seenred in plaee by inserting the portion 11 havingrivet-holes 43 between the longitndinally-divided portion 20 of the end extension and riveting the sa1ne in plaee, as when applying the soeket for tl1e elliptical spring. 'lhe parts of the soekets 39 39, whieh enter tl1e opening in part 20 of the end extension 19, are of the san1e eonfiguration in both eases, tl1ns rendering said soekets interehangeable to permit the ready substitntion of: 0110 type of spring for the other.

The 1naking 0f the end portion 0f the truckfran1e as an integral struoture reduces the nnn1ber of parts that enter int0 such a frame to a 1ninirnn1n, simplifies tl1e construction as a whole, and greatly strengthens the trnssend extension withont adding to its weigl1t.

Havin g thus deseribed my invention, what I elaim as new, and desire to seeure by Letters Patent, is-
