HARRY O. STALDER, OF PORTSMOUTH, OHIO.
CAR-TRUCK BVO`LSTER.
SPECIFICATION forming part of Letters Patent No. 661,777, dated November 13, 1900.
'i Application iiled August 16, 1900- Serial No. 27,094. (No model.)
To @ZZ whom, t may concern:
Be it known that I, HARRY C. STALDER, a citizen of the United States, residing at Portsmouth, in the county of Scioto and State of Ohio, have invented certain new and useful Improvements in Oar-Truck Bolsters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which. it appertains to make and use the same.
My invention relates to improvements in car-truck bolsters, and has for its object to provide an I-beam bolster which is simple in construction and yet rigid, strong, and durable and adapted to eifectually withstand strains and wear.
The invention consists of certain features of construction and combination of parts, which will be more fully hereinafter described and claimed.
In the accompanying drawings, Figure lis a side elevation of a car-truck bolster embodying my invention. Fig. 2 is a top plan view of the saine, parts being shown in section. Fig. 3 is a vertical longitudinal section. Fig.- Il is an end elevation.
The numeral l in the drawings represents a pair of I-beams placed opposite each other and forming the sides of the bolster, said beams being rigidly connected at top and bottom by plates 2 and 3, riveted or otherwise secured thereto and to each other, and which effectually serve to prevent the beams from becoming displaced or spreading to the slightest extent under strain.
4 represents the center plate of the bolster, and 5 represents braces securely riveted to the I-beams and forming rigid supports for said center plate and the top plates 2.
5 represents guide-plates secured to the outer sides of the I-beams in line with notches in the top and bottom flanges of the same, and forming therewith guides forY the columns 6.
7 designates a springplank or bar beneath the bottom plates 3, and 8 springs seated on said plank or bar and at their upper end in pockets 9, fixed to the I-beams. These pockets consist of inverted stirrups or plates having lateral end flanges 10, secured to the baseflanges of the I-beams and rigidly united to U shaped braces Il, also secured to the I-beams, and holding said stirrups firmly against displacement or buckling under strain. This construction eifectually compensates for the removal of the metal at `the points where the springs are applied and insures a firm connection of the I-beams at said points.
It will be readily seen from the foregoing description, taken in connection with the accompanying drawings, that the bolster is not only exceedingly simple of construction and embodies a minimum number of parts, but is also durable and of maximum strength, as the parts are not only rigidly united but effectually braced. It is, furthermore, comparatively inexpensive of production and capable of withstanding the strain and shocks to which such devices are subjected in use in an eicient manner, and may be conveniently built and repaired whenever required.
Having fully described my invention, what is claimed, and desired to be secured by Letters Patent, is-
A car-truck bolster comprising I-beams forming the sides thereof, top and bottom plates connecting said beams, a spring plank or bar beneath the bottom plate, an inverted- ,U-shaped stirrup or plate connected to the I-beams, a brace connecting the upper end of said stirrup to the beams, and springs resting on the plank or bar and seated in said stirrup, substantially as set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing Witmesses HARRY O. STALDER.
