OF PITTSBURG, PENNSYLVANIA, A CORPORATION OF SIDE-FRAME eons'rnvc'rron.
Specification of Letters Patent.
Fatented Aug. 25, 1908.
Application filed July 16, 1907. Serial No. 384,040.
To all whom it may concern:
Be it known that I, ()SWALD S. PULLIAM, of Pittsburg, in the county of Allegheny and State of vleimsylvania, have invented certain new and useful Improvements in Side- Frame (fi'mstructioi'i, of which the following is a specification.
This invention relates to side-frame constructions for cars and the prime objects of the present invention are to provide means for readily placing a bolster in the sideframes and removing the same therefrom; and to provide a construction that will protect the side-walls of the bolster-receivingopening from being worn by the bolster.
To these ends my invention consists in a new and improved side-frame construction, in the novel features oi" construction, and in the combination of parts all as fully hereinafter described and claimed.
In the accompanying drawing, which illustrates applications of my invention, Figure 1 is a side elevational view of a side-frame construction embodying my invention; Fig. 2 is a part sectional view and a part side e1evational view showing a modified form of my invention; F ig. 3 a sectional view taken on line 3--3 of Fig. .2; Fig. 4 a perspective view of removable top-plate and its downwardly extending members; Figs. 5 and 6 detail views of plate and upright-member shown in the form of Fig. 2 and Fig. 7 a perspective view of a modified form of plate and downwardly extending members.
Referring to the drawing, the side-frames proper as illustrated and as preferred comprise a top-member 1, a bottom-member 2,
and a skeleton web-portion 3.
The side-frames are each formed with a holstir-receiving-opening 4 having its upper portion at least as wide as the bolster measured over its column-guides and its lower portion contracted and 01 less width than the bolster measured over its column-guides, said opening is adapted to receive the respective ends of a bolster 5. Bolster 5 is provided with column-guides 6.
i In order to admit the holster to its receivingmpcning 4, l. form the top-member 1 with a cut-away portion and with ledges 7.
8 designate holster-springs of the usual form resting upon a spring-seat 9. After the bolster is placed within the bolster-receivingopcning a top-plate 11) having downwardly upright members. the form of Fig. 7 the members 11 are formed extending members 11 is placed in position in the cut-away portion with its ends resting on the ledges 7 thereof and the members 11 within the bolster-receiving-opening. downwardly extending members 11 are 10- eated in said bolster-receiving-opening 4 and constitute bolster-guides adapted to make contact with the column-guides of the bolster. These members 11 are interposed between the sides ofthe bolster and the sidewalls 12 of the opening 4 and prevent the bolster coming into contact with'said sidewalls 12 or any other part of the side-frame proper.
In the drawings, forms of top-plates and downwardly extending members. In the forms of Figs. 4 and 7 the members 11 are formed integral with the top-plate 10, while in the form of Fig. 2, as particularly shown by Figs. 5 and 6, the topplate and its members 11 are made in separate pieces. When made in separate pieces the plate 10 is formed with openings to receive lugs formed on the upper ends of the (See Figs. 5 and 6.) In
with flanges 13 adapted when in position to engage the edges of the side-walls 12.
As illustrated the to'pplate 10 in all the forms is fitted into the cut-away portion and is secured to the ledges or bearing-members 7 of the top-member 1 of the side-frame proper by means of rivets 14.. The topplate bridges the opening and takes the place of the metal removed from member 1 in forming the o ening,
If desired t e top-plate may be provided with lugs 15 as shown in her 1 is formed with recesses or pockets 16 to receive said lugs.
\ Vhat I claim is:
1. In a side-frame construction, the combination with a bolster provided with columnguidcs, of a side-frame proper having its top member cut away to admit a bolster and formed with a bolstcr-receiving-opening hav- The I have shown several the form of Fig. 4. When these lugs are employed the top-meming its upper portion at least as wide as the bolster measured over its column-guides and a lower contracted portion, and a top-plate having a downwardly extending member located in the opening and disposed between the column-guides of the bolster.
2. In a side-frame construction, the combination with a bolster, of a side-frame proper having a bolster-receiving-opening with its upper portion at least as wide as the bolster measured over its column-guides and a lower contractedportion, and its top-member cut away to admit the bolster, a plate located in the cut-away portion of the topmember provided with downwardly extending members located in the bolster-receivingopening and arranged between the sides of the bolster and the side-walls of the bolsterreceiving-opening and engaging, the sidewalls.
4. In a side-frame construction, the combination with a bolster provided with columnguides, of a side-frame proper having a bolster-receiving-opening with its upper portion at least as wide as the bolster measured over its column-guides and a lower contracted portion and its top-member cut away to admit the bolster, said top-member having supporting ledges, a plate located in the cutaway portion of the top-member and constituting a continuation thereof provided with downwardly extending bolster-guides located in the bolster-reoeiving-opening and in contact with the column-guldes of the bolster,
said plate. supported by and secured to the ledges of the top-member.
In testimony whereof I aflix my signature in presence of two witnesses. a
