JOHN B. SHOPE AND ERNEST ALBERT CLOUSNITZER, OF KENEDY, TEXAS.

ICE-SCORING MACHINE.

Application filed December 30, 1924. Serial No. 758,864.

To all whom it may concern:

Be it known that we, JOHN B. SHOPE and ERNEST ALBERT CLoUsNrrznR, citizens of the United States, residing at Kenedy, in the county of Karnes and State of Texas, have invented certain new and useful Improvements in Ice-Scoring Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to ice scoring machines and it is an object of the invention to provide a machine of this general character whereby the standard block of ice may be out or scored into smaller blocks, leaving the standard block en masse for distribution.

Another object of the invention is to provide a machine of this general character comprising a frame supported for movement in. a direction lengthwise and transversely of the block to be scored, the requisite transverse movement being prevented during the period the machine is eifecting the lengthwise scoring of the block.

A further object of the invention is to provide a machine of this general character comprising a body structure supported for movement lengthwise of a trackway, said body structure being also capable of swinging movement in a direction transverse to the trackway, together with means for holding said body structure against swinging movement toward the work during the period the structure is travelling along the trackway.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved ice scoring machine whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as willbe hereinafter more fully set forth.

The novel features of ourinvention will hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in side elevation illustrating an ice scoring machine constructed in accordance with invention Figure 2 is a sectional view taken substan-- tially on the line 22 of Figure 1;

Figure 3 is a view partly in top plan and partly in section of the structure as herein disclosed, the section being taken substantially on the line 33 of Figure 2;

Figure 4 is a fragmentary view partly in elevation and'partly in section showing the machine operating to produce scores in the opposite side faces of an ice block;

Figure 5 is a view in perspective of a block after being scored by our improved machine.

As disclosed in the accompanying drawings, 1 denotes an elongated trackway comprising a pipe or kindred tubular member supported at requisite elevation by the hangers 2. Riding on the trackway 1 are the trolley pulleys or wheels 3, each rotatably supported upon a member 4 interposed between and operatively connected with upper parallel portions 5 of

end members

6 and 7.

Each pair of

end members

6 and 7 converge upwardly at predetermined angle. The member 6 is substantially straight from an embodiment of our .its portion 5 to its opposite or lower end while the lower portion 7 of the member 7 is angularly disposed and arranged substarr tially in parallelism with the portions 5 hereinbefore referred to but outwardly on set with respect thereto.

The portion 7 of one pair of

members

6 and 7 and the opposed portion of the mem her 6 are connected by the vertically spaced beams 8 herein disclosed as of a channel type, while the opposite end members have the lower part of the member 6 and the portion 7 of the member 7 connected by the brace member 9. Both of the members 7 are connected by a pair of vertically spaced parallel members 10 herein disclosed as angle irons while the members 6 are connec ed by a brace member 11 also herein disclosed as an angle iron, said member 11 be ing in parallelism with and substantially coplanar with the upper brace member .10. Supported by the end portions of the beams 8 adjacent to the portion 7 of the member 7 through the medium of the outstanding depending arms 23.

arms 12 is a block 1 1 of requisite dimensions, the central portion of which being provided with the upstanding bearings 15 on the shaft16, said shaft extending in a direction lengthwise of the beams 8.

Disposed vertically through the opposite end portions ofthe bloclr 1 1 are the shafts 17 the upper end portion of each of which being provided with a gear 18 meshing with a gear 19 carried by the shaft 16 whereby the shafts 17 are caused to rotate in unison but in reversed directions. The lower end portions of the shafts 17 have fixed thereto the circular saws 20 of desired radii. V

The applied gears 18 hold the shafts l'? against downward movement while the coacting gears 19 hold said shafts against upward movement but to further hold said shafts 17 against upward movement I mount upon each of said shafts a collar 21 which contacts with the block 14 from below. Disposed around the outer periphery of each o'fthe saws 20 and suitably spaced therefrom is an arcuate guard plate 22 maintained 'in desired fixed position by the i The arms 23 of the outer guard 22 are secured to the block 14: and the adjacent portion 7, while the arms 23 for the inner guard 22, as herein disclosed, are secured to the block 14 and to the 'lower beam 8. The guards 22 serve to prevent the operator coming in direct contact with the sawsduring a working opera tion. r

The inner gear 18 also has meshing therewith a gear 24; carried by the outer end por tion of the shaft 25 substantially perpendicularly related to the shaft 16. This shaft 25 is rotatably mounted in the upstanding bearings 26 arranged on the plate 27, said plate being supported upon the block 14:, the upper beam 8 and extending inwardly of said beam.

The lower portions of the members 6 are provided with the inwardly disposed bearings 28 which r otatably support a shaft 29, said shaft 29 being in driving connection with. the shaft 25 in the well-known manher through the medium of the sprocket chain 30. hifounted upon the shaft 29 in requisite spaced relation are the circular saws 31 the same, in the present embodi ment of ourinventioii, being each of a radius materially greater than the radius of a saw 20. 7

Supported by the upper member 10 and the member 11 at a point substantially midway of the pairs of

end members

6 and 7 is a substantially Ll-shaped frame F the intermediate or base portion 32 of which ea tending a desired distance outwardly of the member 11 and provided at its central part with an outstanding trunnion 33 upon which is mounted for free rotation a roller 34. This roller 34 is adapted to have contact from above upon a suitably supported beam 35 positioned a desired distance below the track 1 and to one side thereof. The structure of our improved machine is such that the weight of the machine when sup ported upon the track 1 maintains the roller- 34 in contact with the beam 35 so that normally the machine, while free to move lengthwise of the track 1, is held against lateral or swinging movement with the track 1 as the fulcrum point.

The roller 34 as herein disclosed has direct contact with a metal strip or track 36 suitably affiXed to'the upper edge or face of the beam 35 preferably immediately adjacent its inner longitudinal margin.

The side members 37 of the frame F provide trackways fora base 38 upon which is mounted a motor M preferably of an electrical" type. As the operating circuit for this motor M forms no part of the present invention it-is believed that a detailed de scription and illustration thereof is unnecessary. v y

The side members '37 at opposite sides of the base 88 are connected by the cross members 39, said members 39 being spaced apart a desired distance in excess of the length of the base 38 so thatsaidbase together with the motor mounted thereon may be longitudinally adjusted with respect to the frame F so that the motor maybe positioned to the best advantage and particularly to permit the weight of the motor to assist in the requisite balancing of the machine to cause the roller 34 to be normally maintained in requisite contact with the beam 35 or more particularly the track 36 arranged thereon. The base 38, as herein disclosed is fixedly maintained in its desired adjustment by the screws 40 threaded through the cross members 39 and having contact with the opposite ends of the base 38.

The drive shaft 41 of the motor M is in driven connection in a well-known manner through the medium of the sprocket chain 42 with the shaft 29 and as the shaft 25 is in driven connection with the shaft 29 it will be at once readily understood that the requisite operation of both sets of

saws

20 and 31 is effected from the single motor VI. l

Our improved apparatus as herein disclosed, is particularly adapted for use in scoring blocks of ice to facilitate distribution and is especially adapted for use in connection with a standard ice block of three hundred pounds andoperates to score the standard block into smaller blocks approximating fifty pounds each as is indicated by the scorelines a and b in Figure 5 of the upon the chute C with the machine in advance of the chute. With the

saws

20 and 31 in rotation, the machine is moved along the trackway 1 which causes the saws 20 to score the opposite sides of the block B at substantially the vertical center thereof and preferably, in practice, to a depth of approximately two and one-half inches leaving the central portion of the block uncut as is indicated in Figure 4 of the accompanying drawings.

The relative assembly of the

saws

20 and 31 is such that after the ice block has been entirely scored along its sides, as at a, the saws 31 will be so positioned that upon swinging movement of the body structure the saws 31 will make the requisite transverse cuts or scores 7) completely through the block, it being understood that each of the saws 31 is of sufficient diameter to effect such cutting. hen the body structure is in this position, the roller 34 is positioned directly above the downwardly inclined notch 43 which is positioned. immediately adjacent the inner end of the metal track 36 so that the body structure may be readily swung or moved laterally. This notch 43 is of a width substantially the same as the diameter of the roller 34 and the inner face of the beam 35 at each side of the notch 43 is provided with the outstanding stop and guide blocks 44. These blocks operate to prevent movement of the body structure lengthwise of the trackway 1 in either direction during this swinging or lateral movement and also assures such lateral or swinging movement to be in a fixed path of travel as the blocks 44 are spaced apart a distance equal to the width of the notch 43 or in other words, have their inner faces flush with the side walls of the notch.

After one block has been properly scored, the body structure is moved back out of the way so that the operation may be repeated on a second block and so on.

By first positioning on the chute a spacer block larger size blocks may be properly cut or scored.

From the foregoing description it is thought to be obvious that an ice scoring machine constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason we do not. wish to be understood as limiting ourselves to the precise arrange-- me-nt and formation of the several parts ierein shown in carrying out our invention 4 in practice except as hereinafter claimed.
