\VILLIAM H. PEARSON, OF BOSTON, MASSACHUSETTS.
DEVlCE FOR LOOKING TRUCKS TO CAR-=BODIES.
SPECIFICATION forming part of Letters Patent No. 644,091, dated February 27, 1900.
Application filed May 31, 1899. Serial No. 718,909. (No model.)
To all 2071,0711 it may concern:
Be it known that LWILLIAM H. PEARSON, of Boston, in the county of Suffolk and State of Massachusettshave invented certain new and useful Improvements in Devices for Locking Trucks to Oar-Bodies; and I do hereby 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. I
My invention relates to an improvement in devices for locking trucks to car-bodies, the object of the invention being to provide simple and efficient means for supporting cartrucks in their normal position relative to the car-body during the process of lifting the latter from a derailed position to the tracks.
WVith this end in view my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter more fully described, and pointed out in the claims.
In the accompanying drawings, Figure 1 represents a view of myinvention applied in its operative position. Fig. 2 is a detached view of same, and Fig. 3 is a detached view of one of the cams.
A represents a frame, preferably of elongated U shape, the side members 1 l of which are parallel and are separated sufficiently for the free passage of a king-bolt 2 between them. The frame A is sufficiently long to extend well under the truck-transoms 3, and the side members 1 1 thereof are separated for v ment by nuts 6, secured onto the ends of the bolts or by locking pins 7 passed through holes in the bolts, said locking-pins being connected to the adjacent members of the frame A by suitable chains 8, whereby their loss or accidental displacement is prevented. The adjacent ends of cams 4t 4 are each provided with a V-shaped serrated jaw 9, located eccentric to the axis of said cams, between which the king-bolt 2, carried by the car-body, is to be gripped. The serrated faces or jaws 9 of the cams are so constructed that the weight of the free or longer ends of said cams or a downward pull or pressure thereon tends to clamp the king-bolt firmly, and it will also be seen that an upward pull on the king-bolt, as would be the case when jacks are put under the car-body and the latter lifted, also tightens the cams against the king-bolt, so that in applying my device to a car it will be simply necessary toplace the frame A under the transoms, with'the cams thereon engaging the king-bolt and turn the cams sufficiently to engage the king-bolt.
The device above described is adapted to rest when in its operative position against the bottom face of the truck-transoms, as before described, and in such a position as to receive and lock between its serrated jaws 9 9 the depending end of king-bolt 2, and as the latter is secured at its upper end to the framework of the car-body it will be apparent that the entire truck will be supported during the operation of moving a car from a derailed position to the tracks and in such manner that said truck will be free to swing as occasion may require. 7
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. Anattachmentforsupportingcar-trucks from king-bolts, consisting of a frame and means mounted therein and adapted to engage the king-bolt for locking said frame to the king-bolt below the truck-transoms.
2. An attachment for supporting car-trucks from king-bolts, consisting of a frame adapted to rest against the bottom face of the trucktransoms, and means carried by said frame and adapted to engage the kin g-bolt for looking said frame thereto.
3. An attachment for supporting car trucks from king-bolts, consisting ofa frame, and a pair of cams pivotally mounted therein and adapted to lock said frame to the king-bolt.
t. An attachment for supporting car-trucks by king-bolts, consisting of a slotted frame, and a pair of cams pivotally mounted in said frame, said cams being provided with serrated jaws for the purpose of engaging the king-bolt.
5. An attachment for supporting car-trucks by king-bolts, consisting of a slotted frame, a pair of cams removably mounted in said slotted frame, and means for preventing the accidental displacement of said cams, substantially as and for the purpose described.
In testimony whereof I have signed this specification in the presence of two subscrib- :0 ing Witnesses.
WILLIAM H. PEARSON.
