SPECIFICATION forming part of Letters Patent No. 478,731, dated July 12, 1892.

Application filed March 11 1892.

To all whom it may concern.-

Be it known that we, JOSEPH B. BANCROFT and ALONZO E. RHOADES, of Hopedale, county of IVorcester, State of Massachusetts, have invented an Improvement in Beam-Trucks, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

Wound beams, the product of warping-machlnes, frequently weigh several hundred pounds, and two or three men are required to take the said beams from their journals and put them on the usual truck to be taken to the next machine where the beam is to be used.

In our studiesto devise a practical means by which one man or a boy may remove one of these large wound beams from a warpingmachine and transfer it to a suitable point to be used we have made a truck and provided it with lifting-arms and actuating devices therefor, whereby the arms when made to engage the beam-journals may be actuated to gradually lift the beam from its bearings and deposit the same on the truck.

Figure 1 represents an end View of a warping-machine having a full beam ready to be removed, said figure also showing the truck. Fig. 2 is a right-hand end view of the parts shown in Fig. 1, and Fig. 3is a diagram showing some of the different positions assumed by the lifting-arms.

In the drawings, letA represent part of the frame-work of a warping-machine of usual construction; 13, the beam-rotating drum; 0, arms pivoted at D and having bearings for the reception of the shaft E of the beam F on which the warp is wound, the said parts being all as common.

The drawings show the warp-beam as full, ready to be removed.

We have provided a truck G, having suitable wheels 9 g g g, the former being at the ends of the truck and thelatter opposite each other between one and the other end of the truck. The truck is provided with a shaft H, providedrwith two like cranks I, to which are attached lifting-arms J, suitably forked or notched to engage the ends of the shaft or $erial No. 424,486- (No model.)

beam to be handled, the notches of the arms being located at any desired distance from their ends. On the shaft H is a worm-Wheel h, engaged by a worm h on a worm-shaft 71?, provided with a suitable handle or projection 713, by which to rotate the said worm-shaft. The truck is shown as provided with a fulcrum m for each lifting-arm and with a back-stop n for said arms.

Assuming the beam as having been filled,

3. Then in the further rotation of the crankshaft the arms will slide upwardly on the fulcrum and at the same time lift the shaft, and the arms G will swing upwardly about their pivots D until the open mouth of the bearings of the arms G come into a position to relieve the shaft E, and then the lifting-arms, acted upon at their lower ends by the cranks,

will be rocked on the fulcrum into the dotted-f,

line position marked 3, Fig. 3, and then the lifting-arms will be moved or permitted to turn about their pivots c, and carrying the beam come to rest against the back-stop n in the position marked 4, and then in the further rotation of the crankshaft into the position marked 5, the beam will be deposited on the truck ready to be taken away. The truck having the lifting-arms and operative devices therefor enables one man or a boy to do the work of two or three men.

It is not intended to limit this invention to o the exact mechanical devices employed to actuate the lifting-arms or to control the same duringtheir movements. Having described our invention, what we claim, and desire to secure by Letters Patent, 5

1. In a beam-truck, lifting-arms adapted to engage the journals of the beam to be lifted, combined with actuating devices for said lifting-arms, substantially as described.

2. The truck, its crank-shaft, and connected lifting-arms, combined with devices to rotate the crank-shaft, substantially as described.

3. The truck, its crank-shaft, and connected 5 lifting-arms, combined with devices to rotate the crank -shaft and with the fulcra over which the lifting-arms slide, substantially as described.

4. 'lhetruck, its crank-shaft, and connected [0 lifting-arms, combined with devices to rotate the crank-shaft and with the fulcra over which the lifting-arms slide, and a backstop for the arms, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of I5 two subscribing witnesses.
