ICE HARVESTING OR CUTTING lVlACHINE.

SPECIFICATION forming part of `Letters Patent No. 433,953,.dated August 12, 1890.

Application iiled May 2, 1890. Serial No. 350,346. (No model.)

To all whom it may concern:

Be it known that we, JAMES M. MOODY andv SIDNEY B. MOODY, citizens of the United States, residing at Harwich, inthe county of Barnstable and State of Massachusetts, have invented a new and useful Ice Harvesting or Cutting Machine, of which the following is a specification.

This invention has relation to ice harvesting or cutting machines; and the objects in View are to provide a machine so constructed the claims.

-Referring to the drawings, Figure 1 is a vperspective of an ice-cutting machine constructed in accordance with our invention. Fig. 2 is a bottom plan view. Fig. 3 is acentral longitudinal section looking toward the traction-wheel. Fig. e is a front elevation. Fig. 5 is a detail in perspective of one of the depending supporting standards or knees and the gage. Fig. 6 is a detail in perspective of the portion of the periphery of the tractionwheel. Fig. 7 is a detail in perspective of the saw-elevating yoke and the gears for operating the same.

' Like numerals of reference indicate like parts in all the gures of the drawings.

1 designates the platform of the machine, upon which is located the seat 2 for the operator. The platform is provided with a depending surrounding frame 3, to which there is connected removably the mechanism-supporting frame 4 of rectangular or oblong shape. rlhe frame 3 is provided with a series of hooks 5, pivoted thereto, which take into eyes or keepers 6, projecting from the frame 4. The lower frame 4 is provided with a longitudinally-disposed beam 7, and upon the under sides of the beam 7 and the two side bars of the frame 4 there is located a pair of `aligning bearing-boxes 8, in which is mounted for free movement a shaft or axle 9. In rear of the boxes 8 there is mounted upon the un- Mounted loosely'upon the axle or shaft 9 is a traction-wheel 1l, provided at ono side with a driving-gear l2, also loose upon the shaft, and beyond said drive-gear there is keyed to the shaft a pinion 13.

Between the opposite bar of the frame and the beam 7 upon the shaft or axle 9 there is loosely mounted a pair of hangers 14, in the free ends of which is journaled a shaft or arbor 15, upon which is fixed the ice-cutting saw 16 and a pinion 17. Opposite the pinion 17 upon the shaft 9 there is mounted a large gear 1S, whichengages and drives the pinion, said gear being fixed or rigid upon the shaft or axle 9.

In the boxes 10 there is mounted a short transverse shaft 19, fixed .upon which is a small pinion 20 and a large gear 2l, said smallpinion meshing with the drive-gear 12 and the large gear 21 meshing with the small pinion 18, before mentioned. The periphery of the traction-wheel is provided With a series of radiating teeth 22, the rear walls of which arebeveled, as at 23, and between the teeth the periphery of said wheel is oppositely inclined, as at 24, so that no accumulations of snow, ice, or slush can occur.

To the under side of the front and rear end bars, at their opposite ends, are secured L- shaped knees or depending standards 25, braced by diagonal braces 26, and provided upon their upper sides near their ends with bearing-eyes 27. Those knees or standards at that side of the frame in which is located the ice saw or cutter are longer and project farther from the machine than do those at that side of the machine at which is located .the traction-wheel, and said longer standards are provided at their lower extremities with shoes or runners 28. Vlien in motion, one side of the machine is supported by the traction-wheel and the opposite side by the said shoes or runners 2S. Upon the outer facesof the depending portions of the L-shaped standards are located vertically-opposite pairs of headed studs 29, and mounted upon the studs for vertical reciprocation are guide or gage plates 30, vertically slotted, as at 3l, to receive the shanks of the studs.

extended at one side, as at 32, at one side of the machine, and at the opposite sido extended in an opposite direction, and in said exten- IOO The plates are foot of the operator from his seat.

sions' or projectonsare pivoted, as at 33, the lower ends of connecting-rods 34. 'Mounted in the bearing-eyes before mentioned, upon each pair of laterally-opposite standards, is a crank-shaft 35, each-of said shafts terminating at its ends at the ends of the standards in oppositely-disposed cranks 36, which have their ends pivotally connected to the upper ends of the connecting-rods, so that when one pair of cranks at one side of the machine is depressed the opposite pair at the opposite side is elevated, and with them the guideplates of the standards. 'Each of the crankshafts is provided between its bearings and at one side of the machine with similarly upwardly-disposed crank portions 40, said portions being connected by a longitudinally-disposed rod 41, which may be operated by the The shaft or arbor 15, upon which is mounted the ice-cutting tool, is loosely journaled at its ends in an inverted-U-shaped yoke 42, the upper end of the yoke projectingthrough an opening 43 in the platform of the machine and pivotally connected, as at 44, to a hand-lever 45, which is pivoted at its front end in a bearing-eye 4G, and is provided at its opposite or free end with a keeper 47, loosely embracing a toothed and curved standard 48, secured to the platform. The lever has also pivoted thereto a pivoted locking-bolt 49, whereby the operating-lever may be raised and lowered and adjusted at any desired position, and during said raising and lowering will raise and lower the ice-sawing 'tool and its supporting hangers.

' In operation the machine is drawn along by horse or other power, and the mechanism for cutting the ice operated by the rotations of the traction-wheel. The traction-wheel is Vloose upon the shaft and the pinion 13 and gear 18 rotated by reason of the train of gearing described much more rapidly, which lspeed is further increased by transmission to thepinion 17 and the saw-arbor, so that an exceedingly slow rotation of the tractionwheel causes an exceedingly rapid rotation of the saw 16. The depth of cut of the saw 1G is conveniently regulated by the raising and lowering of the operating-lever before mentioned, and also said saw may be raised entirelyfrom contact with the ice, as when the machine is traveling from one eld of ice to another. After the first cut has been made the lower curved ends of the guideplates of those standards having the shoes or runners are projected by the operator through the medium of the crank-shafts to points below said standards, and are entered into the sawkerf just formed, and the machine proceeds back to the startingpoint, and after such 'point is reached is turned for a new cut and the crank-shafts oscillated to withdraw the guide-plates last in action and project the opposite pair of guide-plates beyond the lower ends of the opposite pair of standards, so Vthat they will take into the kerf formed upon u A the return tr1p and ride 1n the samedurlng theV formation ofa new cut. In this manner itis apparent that each successive cutis precisely parallel with the remaining cuts and in cross-sawing exactly square cakes of ice are produced.

It will be observed that the machine at all times rests upon the traction-wheel and the two runners, which runners, being located at a distance from the side of the machine, serve to throw the major portion of the weight of the machine upon the traction-wheel.

From the above description it will be apparent that we have provided a most rapid and accurate ice-cutting machine, of simple and cheap construction, and capable of producing uniformly-proportioned cakes of ice,

' whereby the latter may be snugly stored with a great saving of room.

Having thus described our invention, what we claim is l.
