JO N R. snow, or CHARLOTTE, MICHIGAN ICE SCORING MACHINE Application filed December 26, 1929. Serial No. 416,535.

The main objects of this invention are:

First, to provide an ice scoring machine which is automatic in operation, oflarge capacity, and at the same time comparatively simple in structure.

Second, to provide an ice scoring machine in which the driving means for the elevator is automatically controlled by the deliveryof the work to the elevator.

Third, to provide in an ice scoring machine an improved elevator drive and control means.

Fourth, to provide in an ice scoring machine an improved safety means whereby the machine is automatically stopped in the event of failure of the operating means.

7 Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing, in which:.

Fig. 1 is a side elevation of my improved ice scoring machine.

Fig. 2 is a transverse section on line 22 of Fig. 1.

F Fig. 3 is a transverse section online 3-3 of In the embodiment illustrated the frame 1 is built up of structural steel and is of a suitable character to support the various parts, but as the details of. this frame are not made the subject matter of this application they are not described herein except as the other parts are related thereto.

The elevator guide rods 2 are mounted in the frame in an inclined position, that is, they are inclined relative to a vertical plane. The entire frame structure in the embodiment illustrated is supported in inclined position by varying the length of the

legs

3, 4 and 5. This permits the other parts of the frame to be easily assembled.

The elevator 6 is slidably mounted on these guide rods, the platform proper of the elevator beingmounted on the slides-7 carried by the rods so that the elevator reciprocates' or travels in an inclined path. The elevator 5 lifting cables 8 are provided with winding drums 9 carried by a sleeve 10 on the elevator driving shaft 11.

A clutch designated generally by the numeral 12 is provided for connecting the sleeve to the shaft, and the bell crank 13 is provided for the shifting of this clutch. This lever is connected by a link 14 to an arm 15 on the rockshaft 16 disposed at the rear end of the machine. This rockshaft 16 has anarm 17 projecting forwardly to support the clutch actuating member 18 which is positioned to act as a bumper for the blocks of ice as they are delivered on to the elevator. The upper end of this actuating member is supported by a link 19.

With this arrangement the work, or blocks of ice, sliding on to the inclined elevator platform engages the clutch actuating member-18 which actuates the rockshaft and, through the connection described, engages the clutch, thereby starting the winding drums to lift the elevator. i

The work is delivered from the elevator on an inclined chute 20 having a trip 21 associated therewith to be engaged by the work discharged upon the chute by the elevator. This chute is disposed so that when the inclined platform of the elevator comes'into alinement therewith the work slides upon the chute and, engaging the trip 21, actuates the rockshaft 16. The trip is connected to an arm 22 on the rockshaft by means of the link 23. f

This actuation of the rockshaft releases the clutch 12 allowing the elevator to fall or return to its initial or receiving position. The upper end of the actuating member 18 terminates adjacent the plane of the chute .20 so thatthe clutch is-held in engagement until the work is discharged upon the chute.

As the work is lifted by the elevator it is acted upon by the saws 24 mounted in suitably spaced relation upon the shafts 25 disposed at each side of the path of the elevator. These saws are arranged in a plane below the discharging position of the elevator.

The work is delivered to the elevator by thev feed chute 26 which isdisposed in an inclined position so that the work arranged thereon slides down the same and on to the elevator platform. As the work travels along this feed chute it is acted upon by the saws 27 mounted on the vertically disposed shafts 28 at each side of the feed chute. The shafts 28 are provided with beveled gears 29 at their 7 upper ends while the shafts 25 are provided with beveled gears 30.

The transmission shaft 31 is disposed transversely of the machine and provided with beveled gears 32 which mesh with both the saw shaft gears 29 and 30.

One of the saw shafts 25 is provided with an extension 33 the front end of which is supported in a bearing 3 and connected bythe universal joint 35 to the driving shaft 36 geare'd'to the motor 37. The shaft 11 is provided with the beveled gear 38 at its forward end meshing withthe beveled gear 39 on the transmission shaft 40, which is connected to the saw shaft having the extension 33 by worm gearing arranged within the housing 41.

To prevent breakage in theevent of failure of operation of the clutch control mechanism, such as might result from clogging, I provide a safety switch control mechanism for the motor designated generally by the numeral 42 and provided with a trip lever 43 projecting into the path of the elevator to be engaged thereby in the event of an abnormal travel or stroke of the elevator. The electrical connections for the control member to the motor are not illustrated as these will be readily understood.

My improved ice scoring machine is of large capacity, is automatic in operation, it only being necessary to deliver the work to the feed chute, and at the same time is comparatively simple and economical in structure.

-I have not attempted to illustrate or describe certain embodiments or modifications which I contemplate as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
