1905. Serial No. 255,154.

To all whom it may concern:

Be it known that I, FRANK I. ELLIs, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Pipe Orushmg and Shearing Machine, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation of my improved machine, and Fig. 2 is a vertical longitudinal section looking toward the rear.

My invention relates to the crushing and cutting off of pipes, tubes, or similar articles. Heretofore inthis work the pipe has been crushed down in one machine and then taken to another machine and sheared into lengths.

My invention is designed to provide a single machine which will perform both these operations, the shearing or cutting operation preferably taking place simultaneously with the crushing down of another portion of the pipe or tube.

In the drawings, 2 2 represent the end housings of the machine, having open windows and provided in their upper portions with bearings for the main shaft 3. This shaft is provided with cranks 4 4, which act upon the pitmen 5, pivotally connected to a cross-head 6, moving between the side guides 7 7. To the lower part of the cross-head is secured the crushing-head 8, which is preferably flat on its lower face through a major portion of its length, with the end portions curved upwardly, as shown at 9. This crushing-head coacts with the fiat bed-plate 10, on which the pipe rests when shoved through the end windows, this bed-plate being removably bolted in position.

At the outer side of one of the end housings is the vertical slide or plunger 11, actuated by eccentric 12 on the main shaft and carrying at its lower end the upper shearblade 13, which coacts with the stationary shear-blade 14, removably secured to the foundation and preferably to the bed-plate by the bolts 15, extending into a recess in the bed-plate. The up er shear is preferably inclined longitudina ly, as shown in Fig. 1, and the blades pass each other in the ordinary manner. To counterbalance the shearblade, I preferably employ a weight 16 on lever 17, fulcrumed at 18 and linked to the shear-blade plunger at 19.

Theshaft 3 may be driven by any desirable connections, and I have shown an electric motor 20, supported on an extension 21, extending between the housings at the back side and having a pinion 22 on its shaft. The pinion 22 engages a toothed wheel 23 on shaft, carrying a pinion 24 at its other end. The pinion 24 engages a toothed wheel 25 on the shaft 26, having at its other end a pinion 27, engaging the gear-wheel 28, which is loosely mounted on the main shaft and may be connected therewith by clutch 29. In using the device the pipe is shoved in through the housing-window to the proper distance, and a portion of its length is then crushed down by the reciprocating head 8. The head then moves up and the pipe is shoved along a further portion of its length, the crushed portion passing underneath the upper shear-blade. As the crushing-plunger descends and crushes another portion of the pipe the shear at the same time outs olf the previously-crusheddown portion.

The advantages of my invention result from the reduction in labor and the handling of the pipe, the saving in time, and the combining in a single machine of both operations. The power may be furnished by a hydraulic, steam, or pneumatic cylinder, and many changes may be made in the form and arrangement of the shear, the crushing-head, the driving mechanism, and the other parts without departing from my invention.

I claim 1. A machine for the purpose described, having end housings, a crank-shaft ournaled in said housings, a crushing-head arranged to reciprocate within the housings and operated by said shaft, and shear mechtially as described.

2. A machine for the purpose described, having end housings, and side guides within the housings, a reciprocating crushing-head working in said guides, a fixed bed-plate below the head, shear mechanism, and means for operating the crushing-head, and shear mechanism simultaneously to shear one portion of a pipe while another portion is being i crushed down; substantially as described.

anism also operated by said shaft; substan- 3. A machine for crushing and shearing pipe, having end housings provided with open windows, a crank-shaft journaled in said housings, a cross-head mounted to reoiprocate Within said housings, operating connections between the cross-head and the said shaft, a vertical slide or plunger at the outer side of one of the housings, a shear-blade carried thereby, a fixed cooperating shear-blade, means for actuating the slide or plunger from the said shaft, and a fixed bed-plate arranged to coact with the crusher-head; substantially as described.

4. In a machine of the character described,

a pair of end housings, a flat bed-plate between said housings, a orushing-head arranged to reciprocate between said housings and having a flat lower face with upwardlycurved ends, and shear mechanism outside of one of said housings at right angles to the crushing-head substantially as described.

In testimony whereof I have hereunto set my hand.

FRANK 1. ELLIS.
