Description
UNITED STATES PATENT OFFICEo HENRYBODENSTEIN, OF STAATSBURG, NEWV YORK 'INSERTED TOOTH FASTENIN FOR ICE-PLOWS.
SPECIFICATION forming part of Letters Patent No. 365,570, dated June 28, 1887. Application filed March 1d, 1887. Serial No. 231,402. (No model.)
To all whom it may concern:
Be it known that I, HENRY BODENSTEIN, of Staatsburg, in the county of Dutchess and State of New York, have invented a new and Improved Inserted Tooth Fastening for Ice- Plows, of which the following is a full, clear, and exact description. 1
My invention relates to an improved in serted tooth fastening for ice-plows, andhas for its object to provide a fastening that will accommodate itself to thevarious inclinations of the inserted teeth of an ice-plow and hold the same firmly and rigidly in position, yet admitting of ready adjustment.
The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of a part of an ice-plow to which my improvement has been applied, parts being broken away;and Fig. 2 is a plan view thereof. Fig. 3 is a transverse vertical section through line a: w of Fig. 1, and Figs. 4 and 5 are perspective viewsof the wedges. Fig. 6 is a transverse vertical section of a modification.
A representsthe plow-beam, which is made in two parts, placed at such a distance apart as to receive between them the plowplate sections B, and which are secured to each other and to the said plate-sections B by bolts 0.
The forward edges of the plate-sections B are concaved upon the arcs of circles and beveled to receive the grooves B, formed upon the convexed edges of the teeth D so as to hold the said teeth from lateral movement. The forward edge of each tooth D is concaved, and
against it rests the rear edge of a stop-plate,
F, whichis made of such a thickness as to fit between the parts of the beam A. The rear edge surface of the stop-plate is provided with a centrally-concaved recess, f, whereby two end bearing-surfaces, ff, are produced, the faces of which have an inclination outward, enabling the said plate to obtain a clear and even purchase upon the concave surface of any tooth inserted, even though they vary in width. The outer or opposite edge, 9, of the stop-plate is made convex, and at the lower end, upon one side or both, a projection, g, is formed, to prevent the plate from dropping out from the beam when loosened and the plow reversed. The top of the plate F is pro vided with an integral T-head, g which not only serves'as a means for adjusting the plate in position, but also prevents the same from dropping through the frame from the top. The lower end of the side projection, g, is beveled,so that it will not offer an obstruction to the ice-chips. The said projection may,however, be dispensed with, and a set-screw, Z), or rivet, as shown in Fig. 3, entered into the plate, thepoint entering a longitudinal groove, a, in the opposing beam-section.
H is a wedge-key, which is made straight upon its rear edge, h, the said straight edge being adapted to bearagainst the convex surface of the stop-pin. The forward edge of the wedge, which is made wider at the bottom than at the top, is provided with a central concaved recess, h, whereby two bearing-surfaces, 10k, are produced, having a slight inclination inward to adapt them to the con vexity of the section-plates B. One side edge is provided with a bevel, is", so that the least surface will be presented to the ice-chips, and the upper end of. the wedge k is reduced and threaded, adapted to receive a conical washer, m, and nut m.
In operation the stop-plate is placed be tween the plow-plates with the convex surface to the front. When the-plowis assembled the teeth are then placed in position, a stop plate facing each tooth. The wedge-key is then entered to a connection of its perpendicular edge with the convex edge of the plate, and the nuts are thereupon screwed down until the wedge-keys have driven the stop-platesin close contact with the teeth and the teeth in rigid contact with the plate-sections. B.
it will be observed that,due to the peculiar formation of the stop-plate and wedge-key,an even and positive bearing-surface of the same upon each other and upon the teeth and plate- I
