ICE-CUTTING MACHINE.

Specification of Letters Patent.

Patented Feb. 1 1, 191.1.

Application filed April 9, 1910. Serial No. 554,423.

To all whom it may concern:

Be it known that I, JAY S. LAMBERT, a l

citizen of the United States, residing at Marshalltown, in the county of Marshall and State of Iowa, have invented new and useful Improvements in Ice-Cutting Machines, of which the following is a specification.

This .invention relates to an ice cutting machine of that type including an engine driven saw or cutter.

The invention has for one of its objects to provide an extremely simple, eflicient and practical cutting machine which has a large cutting capacity and can be readily operated by one man.

With such objects in View, and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention;-Figure 1 is a side view of the machine. Fig. 2 is a plan view thereof. Fig. 3 is a detail view of one of the devices for guiding the movement of the machine.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, 1 designates the side beams of the bed or body of the ma F chine, which beams are supported on cross pieces 2 that have secured to them, the runners 3. On the bed is mounted an internal combustion engine A of any approved type which serves to drive the rotary cutter or saw 4:. This saw is secured to an arbor or shaft 5, which has its ends journaled in bearings 6 mounted on a forwardly extending swinging frame composed of side bars 7 that are held in spaced relation by a cross r piece 8 and braces 9 between the cross piece and side bars. The rear end of the frame swings on an axis co-inciding with the engine shaft 10 and if desired, the ends of the shaft 10 may form the pivots or pintles on which the said frame swings. On the saw shaft or arbor 5 is a sprocket wheel 11 around which passes a sprocket chain 12 that also passes around the sprocket wheel 13 on the engine shaft so that the saw will be driven. 'The members 7 form the distance bars between the saw and engine so that the saw can be swung up and down without changing the tension of the sprocket chain. Secured to the bed of the machine are upwardly and rearwardly extending handle bars 1 1 that carry a transverse grip bar or handle 15, whereby the machine can be pushed forward and this handle device is supported rigidly on the bed by standards 16. There are brackets 17 on the handle bars that carry bearings 18 in which the ends of the engine shaft rotate, and these bearings hold the side bars of the saw-carrying frame against lateral movement.

frame, the lever 19 is provided, which is fulcrumed at an intermediate point 20 between two horizontally extending bars 21 secured at their rear ends to a cross piece 22 forward ends on upright members 23 rising from the bed of the machine. The forward end of the lever is disposed centrally of the saw-carrying frame and between this end of the lever and the front ends of the bars 7 of the said frame are connecting rods or links 24. The rear end of the lever is formed into a handle located adjacent the push handle so that the operator can raise and lower the saw-carrying frame as the occasion requires. The lever is held in any position of adjustment by a latch device 25, which engages a notched sector bar 26 secured to the members 21 and extending upwardly therefrom, the sector bar being curved around the pivot as a center.

The movement of the machine can be guided by devices 27 extending laterally from the bed of the machine so as to ride in the preceding cut. These devices are strips of metal extending horizontally from the bed and bent downwardly at their outer ends to engage in the preceding saw cut made by the machine, and these devices can be adjusted for varying the width of the strips of ice to be cut and for this purpose they are provided with spaced apertures in any of which a hook 28 on the bed can be engaged, the said devices are supported in outstanding position by means of the hooks 28 and by engaging additional hooks 29, as shown in Fig. 3.

In operating the device, the saw frame is first lowered by shifting the lever 19 to engage the saw with the ice and when the de- To raise and lower the saw carrying on the handle of the machine and at their" sired depth of the cut is reached, the lever is locked against movement by the latch 25 engaging the notched sector 26. The operator stands behind the machine and pushes the same forwardly by gripping the handle 15. The teeth of the saw are so arranged that they tend to draw the machine forwardly rather than retard its movement so that it takes very little effort 011 the part of the operator to push the machine even when making a ten inch cut. When it is desired to reverse the machine, it is merely necessary to pull downwardly on the lever 19 so as to raise the saw out of the cut, it being, of course, necessary to remove the guides 27 before the machine can be turned. it will thus be seen that the machine can be easily and quickly operated Without any special skill on the part of the attendant.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are within the scope of the claims.

What I claim as new and desire to secure by Letters Patent is 1. A machine of the class described, comprising a runner supported body, an engine mounted thereon and having its shaft eX- tending transversely to the body, spaced bars having their rear ends mounted on the ends of the engine shaft, a saw shaft on the front ends of the said bars, a saw on the last mentioned shaft, a centrally disposed longitudinally extending lever, links connected with the forward ends'of the lever and ext-ending downwardly and outwardly to connect with the forward ends of the said side bars, a push handle connected with the body, a bar extending from the engine and having its rear end fastened to the push handle, an upright on the front end of the body having its upper end connected with the front end of the said bar, and means for fulcruming the lever on the said bar and means on the 'bar for holding the lever in different positions of adjustment.

2. A machine of the class described comprising a runner supported body, a swingin g saw carrying frame extending forwardly from the body, a saw on the frame, anenglue on the body for driving the saw, a handie for pushing the machine, guiding devices projecting laterally from the sides of the body, said devices being in the form of L- shaped members, each having a plurality of spaced apertures, and a pair of hooks for supporting each device, one hook being engai ed in one of the apertures of the device and the other forming a rest for the device.

in testimony whereof I aflix my signature in presence of two witnesses.
