TRUCK SIDE FRAME.
ASpeciication of Letters Patent.
Patented July 29,19136 `Application led April 4, 1913. Serial No. 758,959.
To all 107mm t may concern Be it known that` I, GUS'rav KOMAREK, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Truck Side Frames, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to malte and use the same.
This invention relates to truck side frames of the type in which the journal-boxes are separate and distinct from the side frames and are-removably mounted in same.
In the side frames now in general use which are equipped with standard Master Car Builders journal boxes long throughbolts are-provided for retaining the journal boxes in position, said bolts passing through the Side frames, through lugs on the ournal boxes,` and through tie bars or straps that extend across the under side of the journal boxes. Side frames of the type referred to require constant attention in view of the fact that the vibration of the truck tends to loosen the nuts on the through-bolts, and another objectionable feature of such side frames is the multiplicity of parts. Furthermore, when the side frame is cast in one piece it is necessary to use cores during the casting operation to form holes in the side frame through which the 1through-bolts pass, thus adding' considerable to the cost of manufacturing the side frame.
The main object of my invention is to provide a side frame having integral means for retaining standard Master Car Builders journal boxes in operative position, thereby overcoming the necessity of using througlr bolts or other separate fastening devices for the journal boxes.
Another object is to provide an inexpensive side frame that comprises fewer parts than the side frames of this type now in general use.
Other' objects and desirable features of my invention will be hereinafter pointed out.
Figure l of the drawings isa side ele- A vational view of a car truck side frame constructed in accordance with my invention showing one of the journal boxes in broken lines and the other journal box in vertical section; Fig. 2 is a vertical cross sectional view taken on the line 2-2 of Fig. l; Fig. 3 is a horizontal sectional view taken on the line 3*?) of Fig. l; Fig. 4f is a detail side elevational view illustrating a slight moditication; and Fig. 5 is a detail side elevational view illustrating another modiiication.
Referring to the drawings which illus trate the preferred form of my invention, A designates a car truck side frame which is preferably cast in one piece, and B designates a standard Master Car Builders jour nal box which is arranged in operative position at one end of the side frame, said journal box being provided at its sides with integral perforated lugs l through which long bolts are usually inserted to hold the journal box in operative position in the side frame. Instead of using long through bolts or other separate fastening' devices as' has heretofore been the general practice, I have provided the side frame with integral de vices 2 that project downwardly into the perforated lugs l at the upper end of the journal box and thus prevent the journal box from moving laterally with relation to the side frame, said projections or devices 2 depending from the under side of the portion 3 of the side frame that extends across the upper side of the journal box.
Vertically disposed portions 4c and 5 on the side frame, that lie on opposite sides of the journal box B, prevent the journal box from moving longitudinally of the side frame, said vertically disposed portions being constructed to receive the lugs l on the journal box so that the box can be slipped upwardly between said portions et and 5. In the preferred form of my invention, as herein shown, the vertically disposed portions 4: and 5 are substantially channel-shape in cross section and are arranged with their side legs or flanges projecting toward the Ajournal box so that the edges of same will bear against the sides of the journal box, as shown in Figs. l and 3. The vertically disposed guiding portion 5 at the extreme end of the Side frame, preferably terminates some distance above the lower end of the journal box, as shown in Fig. l, so as to enable the wheel axle with the journal boxes mounted thereon to be run endwise out of the side frames after the Side frames have been jacked up slightly. I also prefer to cut away the intermediate portions of the side flanges of the inner vertically disposed guiding portion 4i, as shown in F ig. 9., so as to reduce the weight. of the side frame and the cost of manufacturing same. lf desired, a pin 6 provided with cotter lreys 7 can be arranged transversely across the under side of the journal box in perforated ears 8 at the lower end of the vertically disposed portion 4 of the side frame so as to eliminate the possibility of the journal box dropping out of the side frame accidentally, as for example, when the wheels become derailed.
In Fig. l I have illustrated a side frame provided with a tie bar or strap 9 that extends across the under side of the journal box so as to perform the same function as the pin`6 of the side frame shown in Fig. l, the ends of said strap being' connected by horizontally disposed bolts l0 or other suitable fastening devices to depending' ears ll on the vertically disposed journal box engaging' portions of the side frame, said bolts being in shear when the strap 9 comes into service. Fig. 5 illustrates a similar' construction except that the bolts or fastening,` devices 10Z1 which retain the tie bar 9a in position are placed in tension when said bar comes into service.
In View of the fact that the side frame is provided with integral projections or devices which are so arranged and designed that they will project into the usual bolt openings of a standard Master Car Builders journal box and thus hold it securely in position, it is not necessary to provide special journal boxes for the side frame, thereby enabling a journal box to be renewed easily or without l`going` to the trouble of sending to the manufacturer of the side frame for a special journal box. Such a side frame also reduces the first cost of the truck owing to the fact that standard journal boxes can be used. The cost of manufacturing the side frame is less than the cost of manufacturing a side frame of the kind heretofore in use as it is not necessary to core holes in the upper portion of the side frame to receive the usual journal box bolts; and still another desirable feature of my side frame is the elimination of separate parts that are apt to work loose and which add to the cost and labor of assembling the truck.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
A truck side frame provided with a horizontally-disposed portion that extends across the upper side o-f the journal-box and two vertically-disposed channel-shaped portions that lie on opposite sides of the j ournal-box, the inner one of said vertically-disposed portions extending downwardly to a point below the j ournal-box and the outer one terminating in the horizontal plane of the wheel axle, a removable member ext-ending transversely through the flanges of the said inner vertically-disposed portion for preventing the journal-box from moving in a vertical direction with relation to the side frame, and integral projections on the under side of said horizontally dispos-ed portion that are adapted to tit in the bolt-openings of a standard Master Car Builders journal-box.
In testimony whereof I hereunto affix my signature in the presence of two witnesses, this 29th day of March 191.3.
