Application filed June 30, 1904. Serial No. 214,803.

Be it known that I, IRA BOYD, a citizen of the United States, residing at Pondhill, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Ice- Cutting Machine, of which the following is a specification.

The invention relates to improvements in ice-cutting machines.

The object of the present invention is to improve the construction of ice-cutting machines and to provide a simple and eiiicient one adapted to carry its motive power and capable of rapidly cutting ice into cakes of the desired size.

A further object of the invention is to provide an ice-cutting machine of this character adapted to accurately cut ice into strips of the desired width and capable of automatically breaking the strips into cakes of the desired size, thereby obviating the necessity of sawing a strip of ice transversely to divide it into cakes.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being under stood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims maybe resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of an ice-cutting machine constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a supporting-frame consisting of a suitable platform mounted upon wheels and carrying the ice-cutting mechanism. The frame is provided at opposite sides with suitable bearings 2 for the reception of a rear axle 3, which is provided with propelling orl traction wheels 4, having spurs or rojections at its periphery for engaging t e ice. The rear axle is located slightly in rear of the center of the machine, and the front of the frameis supported by front wheels 5, arranged on the journals of a front axle 6. The

A front axle is pivotally connected with the frame by a king-bolt or vertical pivot 7, which carries a sprocket-wheel 8, and the latter is connected with a sprocket-pinion 9 of a steering-shaft 10, whereby the axle is turned to change the direction of the machine. The vertical steering-shaft extends through a 'fixed tube or sleeve 11 and is provided at its upper end with a handle-bar 12 or other suitable means for partially rotating it. It is locked in its adjusted position by means of a dog or pawl 13, pivotally mounted on the upper portion of the steering-shaft and arranged to engage the teeth of a horizontal ratchet-wheel 14. The horizontal ratchetwheel 14 is fixed to the upper end of the tube or sleeve. When the steering-shaft is partially rotated, motion is communicated to the axle through the sprocket-gearing, and the machine may be readily turned in either direction. The front wheels are also provided at their peripheries with spurs or projections for engaging the ice to prevent them from slipping. The vertical tube or sleeve extends through the platform and depends from the same, as clearly shown in Figs. 1 and 3.

Mounted upon the rear portion of the frame in suitable bearings is a transverse drive-shaft 15, which is driven by an engine 16 or other suitable motor and is connected with the same by a belt 17 but anyrother form of gearing, either sprocket or spur, or any other means may be employed for communicating motion from the engine to the drive-shaft. The belt 17 is arranged on suitable pulleys 18 and 19 of the engine and drive-shaft, respectively. The drive-shaft is connected with the rear axle by a train of spur-gearing; but any other form of gearing may be employed for this purpose. pinion 19a is keyed or otherwise fixed to the drive-shaft and meshes with a gear-wheel 2() of a counter-shaft 21, which carries a pinion 22. The pinion 22 meshes with a gear-wheel 23, which is keyed or otherwise fixed to the rear axle. The number and diameter of the .gears may be varied to drive the machine at A spur- IOO IIO

side sills or beams of the main or supporting frame. The rotary or circular saw 28 is fixed to the outer end of the saw arbor or shaft, which carries a sprocket-pinion 29 at its inner end, and the sprocket-wheel 29 is connected by a sprocket chain 30 with a sprocket-wheel 31 of the drive-shaft. The sprocket-gearing, which communicates motion from the drive-shaft of the saw-arbor, permits the saw-carrying frame to oscilliate to raise and lower the saw; but any other form of gearing may be employed for communicating motion from the drive-shaft to the saw-arbor. As the machine advances the saw, which is operated simultaneously with the traction or propelling wheels, cuts a kerf in the ice, as will be readily apparent, and the saw is adapted tobe adjusted vertically to suit the thickness of the ice. Also saws of various diameters may be employed.

The sides of the yoke pierce the sides of the oscillatory saw-carrying frame and are provided with nuts 32 for engaging the same. The adjusting-lever, which extends longitudinally of the machine, is located at one side thereof, being fulcrumed on a post or support 33, which extends upward from the supporting-frame. The rear end of the adjusting-lever is provided with an eye or bearing 34, and the front arm operates in an opening 35 of a post 86, preferably composed of two side pieces spaced apart and suitably connected. The post is provided at intervals with perforations 37 for the reception of a pin 38, which also pierces the adjusting-lever, whereby the saw is secured in its adjustment. After the machine has cut one kerf in the ice the machine is returned toits startingoint, and a rotary guide-wheel 39, which is ocated at a point beyond the plane of the saw, is arranged in the kerf for guiding the `machine, whereby cakes of ice may be accurately cut the desired width. The guide is adjustable both laterally of the machine and vertically, and it is supported by an open frame 40 of approximately rectan ular form, provided at opposite sides with s ots 4l for the reception of bolts 42 or other suitable fastening devices, which also pass through slots 43 of horizontal bars 44. The bars 44, which are disposed transversely of the machine, are secured at their inner ends to the front axle, at the front and rear faces thereof, and are angularly bent to clear the adjacent front wheel. The slots, which may be of any desired length, permit the frame 40 to be moved outward and inward, and the bolts form pivots when adjusting the guide-wheel vertically, as they permit the frame 40 to swing upward and downward. The guidecarrying frame is supported or braced by a chain 45, arranged at a slight angle to the front side of the frame 40 and having one of its outer links engaging a hook 46 of the said frame 40. The chain is secured at its inner versely for that purpose.

portion to the supporting-frame by a bolt having a removable nut 47. The bolt of the su porting-frame passes through one of the lins, and its nut 47 engages the same. By means of the fastenin devices of the supporting-frame and the ook of the guide-carrying frame the chain may be varied in length to suit the position of the guide-carrying frame 40.

The ice is weakened by a blade 48 to enable it to be easily and accurately broken into cakes, and this blade is secured to a vertically-movable ice-breaking frame 49, which is automatically operated by the means hereinafter described to break into cakes the strip of ice cut by the machine, thereby obviating the necessity of sawing the ice trans- The verticallymovable ice-breaking frame is substantially U-shaped to form a yoke, which is provided at its bottom with a horizontal bar 50, extending in advance and in rear of the frame. The blade 48 is arranged transversely of the machine at the front end of the bar 50, which is disposed longitudinally of the machine and which is provided at its rear end with a block or piece 51, forming an ice-engaging head and adapted to engage and break the ice in rear of the saw. The transverse blade 48,

which extends across the strip to be broken,

is provided with a lower cutting edge, and it is adapted to weaken the ice, and thereby assist in breaking the same. The verticallymovable ice-breaker is guided by a vertical rod 52, depending from the laterally-extending bar 58 of the supporting-frame and piercing the yoke or frame 49 and the bar 50. The lower portion of the guide-rod is supported by a brace 54, on which is seated a cushioning-spring 55, adapted to cushion the ice-breaker. The coiled spring is interposed between the brace 54 and the top of the yoke.

The icebreaker is provided at the top of the yoke with eyes, into which are linked corresponding eyes of the arms of a forked lever 56, fulcrumed between its ends on a suitable support 57 and connected at its inner end to the rear end of a longitudinally-disposed operating-lever 57` The operating-lever, which is fulcrumed between its ends on a suitable support 58, has its front end arranged adjacent to one of the traction-wheels 4, which is provided with tappets 59, adapted to engage and oscillate the longitudinal lever. l/Vhen the front end of the longitudinal lever 57 is raised, the outer arm of the transverse lever 56 will also be raised, and the ice-breaker will be permitted to drop and break the ice as soon as the tappet releases or disengages itself from the longitudinal lever 57. The

traction or propelling wheels may be of any desired number, and any number of tappets may be employed to cause cakes of the desired size to be broken off by the machine.

Having thus fully described my invention,
