SAMUEL WV. MOMUNN, OF CHICAGO, ILLINOIS.
CAR-TRUCK.
SPECIFICATION forming part of Letters Patent No. 693,984, dated February 25, 1902. Application filed .Tnly 27, 1901. Serial No.69,894. (No model.)
Be it known that I, SAMUEL W. MCMUNN, a citizen of the United States of America,.and a resident of Chicago, in the county ofCook and State of Illinois, have invented Icertain new and useful Improvements in Car-Trucks, of which the following is a specification.
This invention relates to cartrucks, and more especially to that type of trucks in which means is provided to admit of an independent lateral movement of theaxles with relation to the truck-frame proper, an example of which is found in the subject-matter of my prior Letters Patent, No.'646,583,'dated April 3, 1900. 1 v
The present improvement has for its object to provide a simple, durable, and efficient intermediate connection between the'pedestal portions of the truck-frameA and the bearingboXes of the axles adapted to permit the free and independent vertical as Well as lateral movements of the wheels to compensate for track irregularities and in a very effective manner lessen excessive lateral strain upon the wheel-anges, with the consequent wear and liability to fracture of the same,and which, in addition, is adapted to return the parts to a normal position after an independent lateral movement in either direction, as above mentioned, has taken place, all as will hereinafter more fully appear and be more particularly pointed out in the claims. I'attain such ob.- jects by the constructionand arrangement of `parts illustrated in the accompanying drawings," in Which- Figure l is a side elevation of a portion of a car-truck havingvthe present improvement applied; Fig. 2, a detail ltransverse sectional elevation at line as x, Fig. l; Fig. 3, a similar view at line x 0c', Fig. 1.
Similar numerals of reference indicate like parts in the different views.
Referring to the drawings, l representsk a portion of the side frame 'or pedestal portion of a structural-iron carl-truck provided with the usual open-bottomed recess in which the axle-box 2 is contained and in which said box is adapted to have the required free vertical and lateral movements with relation to the truck-frame, but is held from independent longitudinal movement, as usual in the present type of car-trucks.
3 is an intermediate spring, by means of which the particular end of the truck shown in the drawings is yieldingly supported upon the aXle-boX. Such spring will usually be of the spiral form shown; but any other usual and suitable type of 'spring may be used instead, where the circumstances indicate,with out departing from the spirit of this part of the present invention. At its lower end said spring is maintained in proper position against lateral displacement by ,a receivingsocket therefor formed by anannular rim 4: on the top surface of the axle-box 2, as shown in Fig. 3.
5 is a cap-piece formed on its under side with a receiving-socket for the upper end of the spring 3, which socket will usually be formed by a depending rim 6 on said cappiece. The upper surface of the cap-piece 5 will in the present improvement have a flat form to afford a bearing for the suspensionlink by which the truck-frame is supported on said cap, as hereinafter described.
7 is a pivot-rodsecured in sockets at the lower end of vertically-arranged side bars 8 of the aXle-boX-receiving recess of the truck or pedestal and preferably by means of half or semi circular sockets formed in the adjacent or meeting faces of the two angle-iron members, which constitute the side bars 8 in the construction illustrated in the drawings.
9 is a suspension-link, which in the present improvement comprises a duplex formation in which two counterpart vertical members are connected at top by ahorizontal member l0, having a widened form in a transverse direction for purpose hereinafter set forth, while the lower ends of such vertical members are provided with pivot-eyesll, adapted to engage the pivot-rod 7, so `as to Vhave piv-A otal movement thereon. It is preferable to make said'suspension-link of a single piece of bar metal punched and bent into the required shape. Y It is, however, within the scope of the presentinvention to form the same of a built-up construction where the circumstances may soindicate.
It is a material part of the present improvement to form the horizontal member l0 of the suspension-link 9 of a widened form in a transverse direction, in that with such formation and with the same resting upon the flat IOO upper surface of the cap-piece 5 any independent lateral movement of the axle-box in one direction or the other from its normal position will cause a rocking of the said portion or member 10 upon one or the other of its edges to-cause a corresponding compression of the spring 3, so that With a ceasing of the lateral tendency of the axle-box which caused such movement of the suspension-link the spring will exert its force or resiliency to force the parts back to the normal position, with the Ysaid laterally-widened horizontal member l0 lying flat upon the upper flat surface of the cap-piece 5.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is#
l. The combination with a car-truck, and an aXle-boX, of a supporting-spring, a cappiece fitting the upper end of the spring, and suspension-links pivotally connecting said cap-piece with the truck, and having a laterally-widened bearing on said cap-piece, substantially as set forth.
2. In combination with a car-truck, and an axle-box, of a supporting-spring, a cap-piece fitting the upper end of the spring, a pivotrod secured to the truck'frame beneath the axle-box, and suspension-links pivotally counected to said rod, and having .a laterallywidened horizontal member which bears upon the cap-piece, substantially as set forth.
3. The combination with a car-truck, and an axle-box, of a supporting-spring, a cappiece fitting the upper end of the spring, and a suspension member comprising two vertical links integrally connected together at top by a laterally-widened horizontal member, the said member connecting the cap-piece to the truck in a pivotal manner, substantially as set forth.
4. The combination with a car-truck, and an axle-box, of a supporting-spring, a cappiece tting the upper end of the spring, a pi vot-rod secured to the truck-frame beneath the axle-box, and a suspension member comprising two vertical links integrally connected together by a laterally-widened horizontal member Which bears upon the cap-piece, the lower ends of the vertical links having pivotal connection with the pivotrod, substantially as set forth.
Signed at Chicago, Illinois, this 17th day of July, 1901.
