HERBERT R. KEITHLEY, OF BUFFALO, NEW YORK.
CAR-TRUCK.
SI-ECIFICATION forming part of Letters Patent No. 700,425, dated May 20, 1902. Application filed November 27, 1901. derial No. 83,857. (No model.)
To all whgm it may concern;
Be it knownthat I, HERBERT R. KEITHLEY,
' a citizen of the United Statcs, residing at Buf falo, in the county of Erie and State of New York, have invented-new and useful Improvements in Car-Trucks, of which the following is a specification.
This. invention relates more particularly to the frame construction of diamond car-trucks. My invention has for its object to reduce the number .of parts of the truck-frame to a mini mum and to so construct the connected frame members as to increase their riveting area or surfaces, thereby correspondingly increasing Fig. 1. i
The upper arch-bar is preferably constructed webs, as most clearlyshown in Fig. 2.
5o. tions of the lower arch-bar.
Like letters of reference refer to like parts in both figures. v
A is the upper arch-bar, and .B the lower arch-bar, of each side. frame of the truck.
of pressed steel and composed of a'longit'ndinal top plate "ct, two vertical webs a,- extending downwardly from opposite edges of said top plate,- and horizontal fianges'a projecting outwardly from the lower edges of said webs and flanges also preferably extend around the ends of the upper arch-bar, as shown at a Fig. 2. 1 r
In the construction shown in the drawings the crown on the central portion of the upper arch-bar is deeper than its end portions a which latter are horizontal, and the portions thereof between thedeep middle portion and the shallow end portions gradually increase in depth toward the middle portion, as shown in Fig. 1.
The lower inverted arch-bar B may consist of an ordinary solid bar, and its horizontal end portions are secured to the under side of the corresponding portions of the upper archbar by vertical rivets, which pass through the flanges a of theupper bar and the end por- Fig. 2 is an end view of the samej These,
0 represents the usual axle-boxes.
D is the pedestal tie-bar, and E vertical tiebolts passing through the contiguous ends of the two arch-bars and the pedestal tie-bar.
F is the transom, which is preferably constructed of a single blank of pressed steel and composed of a liorizontal'bottom plate f and parallel webs f, extendingupwardly from opposite edges of said plate and each provided at its upper edge with an outwardly-extending flange f The webs f are preferably cons nected together at the ends of the transom by" tie-plates g, which connect; both flanges of the transom and both, flanges of the upper arch-bar, theseplates being secured to said flanges by bolts or rivets h. The end portions of the transom are arranged between the upper and lowerarch-barsof the side frames and are rigidly secured to the lower arch-bars.
by bolts or rivets i, which pass through said bars and the bottom plate" f of the transom,
t, which pass through the tie-plates g, of the transom and the lateral flanges a of the upper arch-bar.
In diamond car-trucks of the ordinary 'con ,struction the horizontal end portions of the and to the upper arch-bars by'bolts or rivets I upper and lower arch-bars are connected together at each end by but two vertical bolts, which receive all of the. shearing strains. Under heavy loads these bolts gradually become bent from such shearing strains, causing a permanent set or downward deflection affords a similar large riveting area for con- 7 nection to the side frames, andby forming the same in asingle piece its strength and stiffness are increased and the number of parts is reduced.
J is the bolster, which is supported on the transom by springs K, arranged within the transom at the ends of the bolster and resting upon plates 70, which in turnrest upon the bottom plate of the transom. The bolster is composed of parallel side Webs j, which have outwardly-extending bottom flanges j and inwardly-extending top flanges 7' a bottom tie-plate, which is arranged beneath and secured to the bottom flanges j by rivets, and a top tie-plate, which connects the side webs and is secured to the inwardly-extending top flanges by rivets. The bolster is preferably provided at each end with a pair of bent guideplates j which are riveted to the side webs above the outwardly extending bottom flanges. These guide-plates bear on the inner sides of the transom-webs and guide the bolster in its movement therein.
I claim as my invention- 1. A side frame for diamond ear-trucks having a lower arch-bar, and an upper arch-bar formed from a single piece of metal, and composed of a longitudinal top plate and vertical webs extending downwardly from the edges of said plate and provided at their lower edges with outwardly-extending flanges which are riveted to the end portions of the lower archbar, substantially as set forth.
2. A side frame fordiamond car-trucks having a lower arch-bar, and an upper arch-bar formed from a single piece of metal, and composed of a longitudinal top plate and vertical webs extending downwardly from the edges of said plate and provided at their lower edges with outwardly-extending flanges which extend around the ends of the bar and which are riveted to the end portions of the lower arch-bar, substantially as set forth.
3. Aside frame for diamond car-trucks having a lower arch-bar, and an upper arch-bar formed from a single piece of metal and having its middle portion constructed of greater depth than its end portions, and composed of a longitudinal top plate and vertical webs extending downwardly from the edges of said plate and provided at their lower edges with outwardly-extending flanges which are riveted to the end portions of the lower arch-bar, substantially as set forth.
4:. The combination with the side frames of a car-truck each having an upper arch-bar or compression member formed from a single piece of metal and composed of a longitudinal top plate and vertical webs extending downwardly from the edges of said plate and provided at their lower edges with outwardly-extending flanges, of a transom composed of a bottom plate, parallel webs extending upwardly from the edges of said plate and formed integral therewith and provided at their upper edges with outwardly-extending flanges, substantially as set forth.
5. The combination with the side frames of a car-truck each having an upper arch-bar or compression member formed from a single piece of metal and composed of a longitudinal top plate and vertical webs extending downwardly from the edges of said plate andprovided at their lower edges with outwardlyextending flanges, of a transom composed of a bottom plate, parallel webs extending upwardly from the edges of said plate and formed integral therewith and provided at their upper edges with outwardly-extending flanges, and plates which are bolted or riveted to the flanges of the transom-webs and to the flanges of said upper arch-bars, substantially as set forth.
Witness my hand this 18th day of November, 1901.
