TRUCK-FRAME AND BOLSTER.

To all 'whom t may concern:

Be it known that I, ALBERT I-I. Voss, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Improved Truck- Frames and Bolsters, of which the following is a specification.

This invention comprehends rnew and useful improvements in railway truck frames and bolsters; and it'contemplates, primarily, the provision of a novel form of truck frame which, by reason of its peculiar construction, may be arranged to support and coperate with the bolster, while the latter is arranged so as to compensate for the traffic shocks incident to the operation of the car or other structure upon which the device is carried.

A further object of my invention is to provide a device of the type in question that is extremely simple in construction, strong and durable, and highly practical from both the standpoint ofthe manufae turer and the standpoint of the user; and which, it is believed, may be manufactured at comparatively low cost.

Various other objects andA advantages will become apparent during the continuance of the following description.

These objects are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in` the following specification and then more specifically pointed out in the appended claims. j

In the accompanying drawings, wherein like characters designate like parts through-y out the several views Figure 1 is a view in plan of my improved truck frame and bolster, showing the same as in their preferred embodiment; y

In the present embodiment, 10 designates the truck frame, of my invention, in its entirety, while the numeral 11 designates the bolster. Since the respective truck frames that are usually employed in connection with a bolster of the type shown are of substantially the same configuration, and construction, only one of such frames will be herein described in detail.

Referring firstly to the truck frame, 12

designates the skeleton body portion thereof` that is preferably formed of cast metal and hollowed out a greater portion of its longitudinal extent in order to provide an open, inexpensive, yet durable structure. Body l2 has located therein, a transverse partition 13 (refer to Fig. 5) the same terminating approximately halfway between the top and bottom sides of the body member, and having a cross slot 14 provided therein, as illustrated.

A depending enlargement 16 is located on the under face of body member 12, substantially midway its ends, said enlargement having provided therein, suitable disposed cut outs 17 (refer to Fig. 4:) that accommodate certain coperating parts of the device, subsequently described. By reason of the construction above elucidated, it is obvious that 100 member 12, has located at its respective 105 ends, vertically alined

branches

17 and 18 respectively, between which may be accommodated a journal boxing or the like, as subsequently described, said branches being connected through the instrumentality of 110 removable bolts, or the like fastening members, as at 19, whereby they may be drawn together sufliciently to grip the journal boxing or other structure engaged. Although not limiting myself in any way to the construction shown, it may be advisable to cut away the upper branch 17 as at 20, in order* to accommodate the head of bolts 19. Other fastening members, such as shown at 21,. mayv be associated with branch members 18, as shown in Fig. 2, in order to securely retain the same in place.

The intermediate portion of body member 12 has located therein, a transverse opening 22 that is substantially alinedwith partition member 13 above referred to, the said opening being designed to receive one end of the bolster v11. Bolster 11, like t-ruck frame 10, is preferably constructed of cast metal or of an approximately similar construction, the end-s thereof being slightly reduced as shown in Fig. 3 whereby .they may be readily accommodated in the openings 22 of ythe truck frame, as previously pointed out. Adjacent one end, bolster 11 is provided with spaced

bearings

23 and 24. between which is provided a socket 25 for reception ofboxing 26 that is substantially U-shaped in cross section, as in Fig. 9. Subsequent to the arrangement of boxing 26', in position, between bearings 23 and 2.4, plate 28, such as shown in detail in Fig. 8, may be engaged with the boxing as in Fig. 3., and a bolt or other securing pivot 29 passed through the said bearings, boxing and plate, in order to firmly secure the relative parts in position. When thus secured in place, carrying plate 28 projectsinto slot 14 of partition 13 above referred to, and also projects to each side of the said partition 13, asshown in Fig. 5,. Socket members 30 may now be pivotally connected to the respective end portions of plate 28 by means of their respective pairs of spaced bearings 31 and fastening members or pivots 32, subsequent to which cushioning. springs 33, preferably yof the heavy duty type, may be positioned. in sockets or spring seats 17 of the truck frame so as to engage with socket members 30' in the manner clearly shown in Fig. 4. Conse-l quently, it will be recognized that bolster 11 will be yieldingly supported with respect to the. truck frame; ,springs 33 compensating for the traffic shocks transmitted to the truck frame from the respective axles 34 and wheels 35.

In order to connect the truck frames in pairs and precludethe possibility of lateral movement .thereof relative to one another, during operation, I preferably equip each frame with an outstanding lug or bearing portion 36 which. carries at its free. terminal, an upstanding lip 37. A connecting plate39 is then employed (sce Fig. 10.), the said, connecting plate having enlargements 40 ateach: end, to. rideupon the" said bearings 36, in theV manner illustrated in Fig. 3. After connecting plate has been arranged in position, a` bolt 4f VorA other suitable fastening member may be passed through the respectiveenlargements and the bearings 36 in 'order to insure an efficient connection there- Y' between.

As will be noted upon reference to Fig. I, I provide truck frame 10 with suitably spaced hooks or bearingA portions 42, in order to facilitate the connecting of the truck frame with the ordinary brakebeam (not shown) by means of the usual chains. rIhese .hook portions'Y are preferably of a nature thatwill permit o f the quick. and easy removal or attachment of the connecting chain, in order to increase the general convenience of the device.

I also provide the bolster 11 with an im.- proved fulcrum casting,` (see Fig. 7), the s ame consisting yof a bearing portion 43, whichl carries right angularly disposed flanges. 44 and 45, for attachment to the respective side and to-p walls of the bolster, as illustrated. Bearing portion 43 is also provided with athrough opening 46. Bolts. 47 may also be utilized for retaining this bracket in position.

From the4 above, it .will be recognized that while the pairs of ltruck Aframes serve to efficiently connect and coperatewith the axles 34 which are, o-f course, of? conventional form, it will also be appreciated that the said truck frames provide an efficient support for the bolster7 and permit of the in.- troduction of means thereinto to yieldingly support the bolster and thus compensate for traffic shocks which would otherwise be conveyed thereto. 4 Truck frames 10 are connected by means of plate 39, shown in detail in Fig. 10, while the bolster 11is free to move vertically therein, during operation of the car or other structure, 'uponl which the device is used.

In reducing my invention to practice I find that the form referred to herein as the 1. The combination of a truck frame mem-l ber having a socketed portion and a slotted partition within the socket thereof, a bolster" having one end disposed abovesaid partition, a member extending through theslotof said partition and supporting one end of said bolster, and means mounted in the socketed portion and at opposite sides of said partition for yieldingly supporting said member.

Q. The combination of a truck frame member provided with a pair of spring seats, vertical guiding elementsbetween said spring seats, a supporting member extending between the said vertical guiding elements, spring seat elements connected to the respective ends of said supporting member, a bolster having one of its ends associated with said supporting member, and springs coperating with the first said spring seat and the second said spring seat and with said supporting member for yieldingly supporting one end of said bolsterT 3. In a device of the character described, the combination with a truck frame member including a centrally located socketed p0rtion and an opening communicating with said socketed portion, of a bolster having one end disposed in said opening, a plate carried by said bolster and having its ends projecting laterally thereof within the socketed portion of said truck frame member, members pivotally mounted at the end portions of said plate, and yieldable means interposed between said members and the face of the socketed portion of said truck frame member to yieldingly support said bolster, substantially7 as described.

4. In a device of the character described, a truck frame member consisting of a skeleton body having a centrally located socketed portion, and a partition in said socketed portion, said partition being slotted transversely, said truck frame member being pro vided with an opening above the aforesaid socketed portion; in combination with a bolster having one end disposedin said opening, a plate pivotally mounted on said bolster and operating in the slotted portion of said partition, members pivotally mounted adjacent the ends of said plate, and coil springs interposed between the base of the socketed portion of said truck frame member and said last mentioned members, to

yieldingly support said bolster, substantially as described.
