ICE-SAW.

Specification of Letters Patent.

. Application filed May 29, 1914.; Serial No. 841,917.

To all whom it may concern Be it knownthat I, WALTER F. MOORE, a

' citizen of the United States of America, re-

siding at Fayetteville, in the county of Lincoln and State of Tennessee, have invented certain new and useful Improvements in Ice- Saws, of which the following is a specifica tion, reference being had therein to the accompanying drawing.

This invention relates to an, ice saw and has special reference to a saw which is adapted to be carried by the body of a wagon for cutting ice into desired quantities when the same is being removed from the wagon body.

Another object of this invention is the production of a saw for the purpose specified which is adapted to be operated by the rotation of the supporting wheels and which is so formed as to be easily shifted so as to remain inoperative when desired.

With these and other objects in view this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings :-Figure 1 is a side elevation of a wagon showing the saw carried, thereby in a position for use. Fig. 2 is a bottom plan view. of the rear portion of a wagon showing the saw in position. Fig. 3 is a'rear elevation of a wagon the saw being shown in position for .use. Fig. 4 is a longitudinal section through the rear portion of a wagon showing the man- Fig. 5 1s a.

ner in which the saw operates. section taken on the line 5-4) of Fig. 1. Fig. 6 is a perspective vlew of the operating lever which is adapted to shift the saw;

Fig. 7 is a section taken on the line 7- 7 of.

Fig. 2. Fig. 8 is a detailed perspective view of a portion of the wagon body showing the ice supported thereby. Fig.9 is a section taken on the line 9-9 of Fig. 5. Fig. 10 is a section taken on the line 10 10 of Fig. 1.

Referring to the accompanying drawings by numerals 1 designates the bottom of the wagon having the sides 2 and 3, this body which is formed by the bottom 1 and sides 2 and 3 is supported by the usual wheels 4 and 5. The bottom'1 is provided adjacent its rear portion with alongitudinally ex-.

tcnding slot 6 through which the circular saw 7 normally extends. This saw 7 is keyed to the shaft 8 which passes through the sleeve 9. Upon each end of the sleeve 9 there is threaded a hollow collar 10 in which there is provided a plurality of bearing rollers 11 so as to cause the shaft 8 to freely rotate since these roller bearings 11 will carry the greater portion of the weight of the saw and the shaft. The sleeve 9 passes through the yokes 12 and these yokes 12 curve slightly toward their lower portions as clearly disclosed in Fig. 7. The upper portions of these yokes are provided with the lateral projections 13 through which the securing members ll pass for fixedly securing the yokes in engagement with the bottom 1 of the wagon. j

For the purpose of supporting the sleeve 9 and shaft 8 adjacent the under surfaceof the bottom 1 of the wagon, the keys 15 may be passed transversely through the yokes 12 so as to allow the sleeve 9 to rest thereon when the saw is in use. "To the end of the shaft 8 opposite to that upon which the circular saw 7 is supported there is provided a pinion 1.6 which is held fixedly upon the shaft.

This pinion is adapted to be engaged by the internal gear wheel 17 which is secured to one of the rear wheels 5 by means of the U- shaped bolts 18 passing around the spokes 19 of the wheel 5 and throughthe internal gear wheel 17 at which time the retaining nuts 20 are placed thereon. This wheel 17 is provided. with the teeth formed upon its inner periphery andis provided with the integral lugs 21 for holding the same in spaced relation to the spokes 19.

It will be seen from the foregoing description that as the wagon is in motion and the rear wheels are rotated the internal gear wheel 17 will drive the pinion 16 which will in turn impart rotary motion to the circular saw 7 by means of the shaft 8. The ice which is in the body of the wagon may be pushed into engagement with the circular saw 7 and since the same is rotated the ice may be cut into blocks of any desired size and quantity. It may be desirable, however,

to place the circular saw in an inoperative Patented Oct. 27, 1914.

position and therefore the arm 22 having a hollow head 23 may be positioned upon the sleeve 9. This arm 22 is adapted to pass upwardly through the slot 2d so as to allow the upper end thereof to receive a pivot pin 25.

adapted to be engaged by the lug 80 of the catch 31. By the use of this device when it is desired to lower the saw and at the same time disengage the pinion 16 and the internal vgear wheel 17 the pins 15 are first withdrawn. The rack catch may be operated so as to allow the lever 27 to swing upon the bracket 26 thereby causing the arm 22 to move downwardly through the slot 24 and in this manner lower the sleeve 9 and shaft 8. Since the yokes 12 are curved the sleeve 9 will move away from the internal gear wheel 17 and thereby cause the pinion 16 and internal gear wheel 17 to become disengaged. Then this has been accomplished the saw will be down below the wagon bottom 1 as disclosed in Fig. 1 so that the inner surface of the wagon bottom 1 will be sufficiently even.

In order to convey the ice to the saw, the wagon bottom is provided with the tracks 32 upon which the groove rollers 33 are mounted. These groove rollers are connected to and support the rectangular frame 34 which comprises the carriage. This frame 34 is provided at one end with a I transverse slot 35 through which the circular saw 7 is adapted to pass as the carriage is moved toward the saw and the ice which is positioned upon the carriage is being out into the desired sizes. It will also be noted that the saw will be held in its correct cen* tral position so as to extend through the slot 6 formed in the bottom 1, since the collars 10 ride upon the outer faces of the yokes 12 as clearly disclosed in Fig. 5.

From the foregoing description it will be seen that a simple and efficient means has been produced for cutting the ice carried by the wagon body into the desired quantities and sizes and which is so formed as to be easily shifted to an inoperative position when it is not desired to use the same.
