COLUMN FOR RAILWAY-TRUCKS.

Specification of Letters Intent.

Application filed June 27, 1911.

To all whom, it may concern Be it known that I, Annual C. MURPHY, a citizen of the United States, and resident of the city and county of New York and State of New York, have invented an Improvement in Columns for Railway-Trucks, of which the following is a specification.

My invention has reference to columns for car trucks and consists of certain improvements which are fully set forth in the following speeification and shown in the accompanymg drawings which form a part thereof.

The object of my invention is to provide an eflicient construction of steel column for trucks which ma be made in an economical manner from ro led steel channel bars. By my improvement, I provide a most satisfactory guide for the bolster and a strong and eilicient means of attachment for the column to thetop and bottom arch barsof the truck frame.

My invention consists of a column formed of a single piece of channel shaped steel bar in which portions of each of the flanges near the ends of the bar are removed and the flanges at said ends bent outwardly and downward] in the reverse direction to their normal position, and the said bar having its ends, so formed, bent backward over the ends of the remainin portions of the normal flanges, whereby t ere is provided a vertical channel bar iide section with top and bottom horizontal or lateral extensions res ctively provided with upwardly and d d ivnwardly extending flanges to form top and bottom sockets for the reception of the to and bottom arch bars of the truck frame.

y invention further consists in the column, above described, combined with a plate welded to one of the flanges of the vertical w--w of Fig. 2; and Fig. 5 is a pore 9" view of the preferred man of inc 0 portion of the structure and said late provided with a bralte carryin brac ret.

My invention also compre ends details of construction, which, together with the feature above described, will be more fully understood by reference to the drawings, in which:

Figure 1 is a perspective view of the column structure embodying my invention; Fi 2 is a side elevation of the same; Fig. 3 1s a front view of the same; Fig. 4 is a cross sectional vicw-of the same on line ective annel bar immediately preceding the bending over of the end portions thereof to form the top and bottom extensions therein.

The entire column, other than the portion thereof which is intended to support the brake device, is formed of one integral piece of channel bar prepared; as a preliminary operation, in the form illustrated in Fig. 5, in which, 2 represents the sha e of a steel channel bar or beam and which is maintained at the middle portion of the bar. Portions of the flanges are cut away correspondin to the parts 5, and the flanges at each end portion 3 of the beam or bar are bent outward and downward, as indicated at 4, to provide flanges to the body of the bar directed oppositely to the normal flanges at the middle of the bar. This bar, so formed, is further provided with the two large holes 6, 6, for the column bolts and said holes are in the portion of the bar which corresponds to the arts in whichthe flanges are cut away and once intermediate of the parts 2 and 3. The end ortions of the body are further rovide with the smaller rivet holes 7 an in addition thereto, rivet holes 8 may be rovided in the body near one end of the mid le portion 2. When the bar is repared in this manner, itis then heated an bent in the form illustrated in Fi 1 and 4, in which the end portions 3, which are beyond the normal flanges of the channel bar are bent over in the direction of said flanges and so that these bent portions of the body may rest upon the ends of the flan es, as clearly illustrated in Figs. 1 and 2. he end portions 3, with the oppositely directed flanges 4, will then project beyond the main portion of the bar and its flanges as clearly indicated in Fig. 2, said flanges 4 of the ovcrhangin end parts 3, respectively projecting upwardly and downwardly and formingsockets 10 for receiving the usual top and bottom arch bars of the side frame of the railwa truck.

The vertica part of the channel bar forms vertical guides 9 with clearly defined rectan- "ular corners and unobstructed sides for the Bolster guides. The holes 7 in the overhanging portions 3 are intended to provide means for riveting the said arts to the upper and lower arch bars. he holes 8 near the bottom of the vertical portion 9 of the column are for riveting the column of the channel beam which supports the bolster fvert-ic'al flanges of the part 2 the vertical portion of the col .w fectly smooth guiding surface. It is evi- "springs. It is evident that these various rivet holes may be madein any suitable place or in any suitable number to meet the requirements in Commercial practice.

11 is the brake-bracketw and is secured to a plate 12 by rivets' 13; said plate 12 being welded atl i to the inner part of one of the constituting umn so that the outer ,portion thereof is left with a pen dent; however, that' this plate 12 may be secured to the column or to the flange thereof in any suitable manner, in place of welding. The upper part of-the' plate'12 is preferably made to fit close against the under side of the upper portion 3 and is'also preferably of a width suflicient'jto extend out to the endof the said part3, as'indicated in Fig. 4:, though this particular proportion is notessential.

While I prefer to remove the flan es at theplaces 5 for a length substantiall to the depth of the flange on the in of'the bar or'beam,1s0 as to avoi the flanges 4 extend over' the vertical of the column in the'finished Figs. 1 and 2) the width of portions ofvthe'flang e may be aried, without departing from the spirit/of the inven tion, that is to say, said p0 ions removedin part having port-ion ticle (see' e removed a maybe greater or less, as desired.

The general construction of my invention embodies a reasonably sm vertical'guiding portion of the column and clearl "formed sockets for top and bot-torn arch a rs without the necessity of m'achining, and hence, is economical in construction -and the boltedunion" of the column with 40- the arch bars may-be so close as not to be liable to work loose byjarring.
