HENRY BODENSTEIN, OF ARLINGTON, MASSACHUSETTS.

ICE-CUTTER.

SPECIFICATION forming part of Letters Patent N 0. 729,122, dated May 26, 1903.

Application filed July 17, 1901.

To aZZ whom it may concern:

Be it known that I, HENRY BODENSTEIN, a citizen of the United States, residing at Ar-' lington, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Ice-Cutters, of which the following is a specification.

My invention relates to improvements in ice cutters or plows, and refers particularly to an improved construction of tooth to be used on the cutter or plow.

One object of my invention is the provision of a tooth which can be easily and readily applied and used upon the form of plows or cutters in general use.

Another object of myinvention is the provision of a tooth which can be easily sharpened and which will receive the force or strain imposed in cutting in a proper manner without damage to the tooth.

Another object of myinvention is the provision of a tooth which can be easily sharpened, which will perform the operation of cutting in a perfect manner, which can be adjusted to the work, and which will be simple, inexpensive,and durable in construction and thoroughly efficient and practical for the purposes intended.

To attain the desired objects, my invention consists of a tooth for ice cutters or plows embodying novel features of construction, substantially as disclosed herein.

Figure 1 represents a side view of an ice plow or cutter, the blades being provided or equipped with my improved tooth. Fig. 2 represents a side view of a portion of one of the blades provided with my tooth, the view being on an enlarged scale. Fig. 3 represents a similar View of a slightly-modified construction. Fig. 4 represents a detail view of the parts detached. Fig. 5 represents a sectional view of a modified form of fastening, and Fig. 6 is a sectional view of a tongue-and-groove connection.

In the drawings, Adesignates' the frame of a plow or cutter provided with the handles B at one end and with a suitable draft attachment O at the other end, and secured to the frame and depending therefrom are the blades or cutters D of the plow. The blades are formed with the heel E and with the adjacent kerf or recess F, forming the inclined Serial No. 68,601. (No model.)

edge G along the lower face of the blade. The said inclined face is provided with teeth or serrations H, and above the same on each side of the blade is formed a groove or channel J, and this construction allows the application of my improved form of tooth. The purpose of the heel on each cutter is to form a stopor abutment for the cutter when the heel contacts with the ice, and thus the heel prevents thedetachable teeth from striking the ice or from going too deep into the ice.

My tooth consists of the bottom wall K, formed at its forward portion with the cutting edge K, and the side walls K which are formed at their upper end with the flanges or guides K which fit snugly in the grooves or channels of the blades and are adapted to be held at any desired adjustment with reference to the blades by the pin or stud L, which passes through the side walls of the tooth and has its upper face formed with serrations L, which engage the serrations of the blade and, as is evident, secure the tooth perfectly to the blade and at any desired adjustment with reference to the blade. Fig. 6 I have shown the tooth and blade as connected by a tongue-and-groove connection.

I claim 7 1. In an ice-cutter, the combination with the blades having the lower downwardly and forwardly inclined serrated edges and the groove on each face parallel with said edge, of the teeth embracing said serrated edges and having inward-extending flanges fitting in said grooves and means passing through the teeth and engaging the serrations of the blades to hold the teeth at the proper adj ustment on the blades.

2. In an ice-cutter, the blades formed with the depending heel portion, the lower serrated edge and the grooves on each side above the serrated edge,the teeth fitting on the'lower edge of the blade and having the flanges fitting the grooves, and the toothed pin passing through the side walls of the teeth and engaging the serrations on the blade to hold the teeth at the desired adjustment, said transverse pin having a smooth face fitting the tooth and a serrated edge engaging the blade proper.

3. In an ice cutter or plow, the combination of a frame, handles carried by the frame,

andaseries of blades or cutters secured in the frameysaid cutters being each formed with a heel portion and a contiguous inclined lower face, a series of teeth on said lower face and a groove or channel on each side of the blade parallel with the teeth,a detachable tooth having a forward cutting edge and provided with flanges fitting in the grooves of the blade for adjusting the tooth on the blade, and means for holding the teeth at the desired adj ust- Io ment.

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

HENRY BODENSTEIN.
