HORACE WARE, OF MARBLEHEAD, ASSIGNOR TO HIMSELF ANl) THOMAS G. WARDWELL, OF METHUEN, MASSACHUSETTS.

ICE-GROOVING PLOW.

SPECIFICATION forming part of Letters Patent No. 231,201, dated August 1'?, 1880.

Application filed March 8, 1880.

To all whom 'it may concern:

Be it known that I, HORACE WARE, of Marblehead, in the county of Essex and State of Massachusetts, have invented a new and 5 useful Improvement in Ice-Grooving Plows;

and 1 do hereby declare the same to be described in the following specification, and rep resented in the accompanyingdrawing7 which is a perspective view of an ice-grooving plow ro provided with my invention, in the carrying out of which I combine with a common icegrooving plow a-nd its reversible gage or guide an intermediate cutter-carrier at'ixed to .the arms of' the guide and furnished with chisels 15 or cutters extending in opposite directions from it, (the said carrier,) each set being for the purpose of marking or scoring the ice between the gage and main plow and parallel to the path of movement of the gage while the zo plow may be in operation.

Generally speaking, such intermediate scoring of the ice is effected by a separate plow, and is accomplished for the purpose of marking the ice where it is to be split by wedges to 2 5 convert it into blocks or pieces of half the width it has preparatory to being stored in an ice-house.

In the drawing, A represents an ice-grooving plow of ordinary construction as provided 3o with a reversible guide or gage, B, which is connected to the plow by two arms, C C, that are hinged to the said plow .in manner to ena- (Model.)

ble the gage or guide to be turned over and used on either side of the plow, as occasion may require. Extending between these arms, 3 5 and attached to them at their middles, is the auxiliary cutter carrier or bar D, provided with two sets of ice cutters or chisels, E E and F F, one of which sets projects upward from and the other downward from the carrier, in 4o manner as represented. Each set of such cutters or chisels is to score the ice or form in it a shallow groove while the plow may be making in it another or much deeper groove, the gage or guide being supposed to be extended 45 into a groove previously made in the ice, and serving with said gage to guide the plow in its proper direction to cause it to cut in a path parallel to the guide-groove.

From the above it will be seen that the aux- 5o iliary groove made in the ice by either set of cutters E E or F F will be formed midway between the groove into which the guide B may extend and the groove made by the plow A.

I claim-- The combination of the ice-groovin g plow A and its reversible guide B, connected to it by arms C U, with the intermediate bar D and its cutters E F, all being substantially as and for the purpose or purposes specified.

HORACE WARE.
