' ICE-SCORING MACHINE.

Application filed August 13, 1924, Seriallio. 731,834.

To all toil-om it may concern:

Be it known that we, J ()SEPH :STRIHENSON' YAGER and L nn STARLING, citizens of the United States, and residents of Greenville, in the county of Washington and State of Mississippi, have invented certain new and useful Improvements in Ice-Scoring Machines, of which the following is a specification.

This invention relates to ice scoring machines and has for its object the provision of a device which is adapted to provide a horizontal out and vertical cuts upon opposite faces of a block of ice whereby the ice may be readily chopped in the usual manner for producing blocks of ice of uniform dimensions.

A further object of the invention is the provision of an ice scoring machine having a movable carrier and carrying saws for causing vertical scores on a block of ice and in which thecarriage automatically and through its own weight is caused to descend for-causing the saws to score the ice.

A further object of the invention is the provision of a device having a movable carriage carrying; vertical scoring implements and stationary horizontal scoring iinpl inents adapted to cause horizontal scores in advance of the vertical scores and which are caused to be operated when the carriage is at its most elevated position.

This invention will be best understood from a consideration of the following detailed description, in view of the acoompanying drawing forming a part of the specification; nevertheless it is to he understood hat the invention is not confined to the disclosure,r,being susceptible of such changes and modifications which shall define no material departure'fi'oin the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure l is a side elevation of the ice scoring machine.

Figure 2 is an end elevation of the same.

Figure 3 is an end elevation of the ice scoring machine where the ice enters the same.

Figure l is a view in perspective of the scoring device with the supporting frameworlr eliminated.

Figure 5 shows a block 03"; ice which has been scored by the machine. I

Referring; more particularly to the drawing made of sections and io ings, 1 represents a base niei'nber which is provided with a track 2- adap d to receive the ice with rollers 5 for Hg in moving the block oi ice readily through the sewing machine lvl'ounted upon the base member 1 are four columns l formed of hollow piptogether by the usual couplings. The columns or standards are connected intermediate their ends by means of cross bars 5, t), 7 and. 8. The parallel cross bars 5 are l rovided with Tjoints 9 whi adapted to support cross bars 10. l 'he cross bars 10 are connected to couplings 11 into which are screwed the vertical guides 12. The lower ends of the vertical guides are screwed into couplings 13 which are supported by transverse bars 14: and 15. The bars lat connect the couplings 13 while the outer ends of the bars 15 are screwed into couplings 16 car ried by the cross bars 8. The transverse bars, as are the standards 4-, are made from standard piping. A hand wheel 1'? drives a shaft- 18 which. is mounted in bearings upon the f ame carried by the standard 4. The shaft 18 car- 'ies a gear 19 which meshes with a rack 20 rigidly connected to the frame of a movable carriage which carries the cutters that produce the vertical'slots. V

lhe movable carriage comprises a table 21 upon which is mounted a motor 22 having electrical connections through the wires 23 with. the house current. Depending from the table 21 and-mounted in sockets 524; se-

,cured to the bottom of the table are four legs of standard pipe construction and braced near their-upper ends by means of transverse rods lhe lower ends of these pipes are b aced by means of rods 27. Can ricd by the lower ends of the legs are bearings 28. In each pair of bearings is mounted a shaft 29 carrying a drive pulley 80. Upon the outer ends of the shafts are provided cutters 31 for producing pairs of vertical cuts in a block of ice. These shafts are driven by pulleys 33 rigid with the horizontal shatts'34.

The motor 22 t rough ashatt 35 drives a pulley 36 around whichia belt 37 is entrained. This belt is carried around the pulleys 38 and 89., each one of which being rigid with a shaft 84-. The belt is further entrained about a pulley or fly wheel {U mounted in bearings carried by the vol-ti cally movable carriage.

the post 4 is providednvith a pair of spaced grooved wheels 46 adapted to support cables 47 which are connected at their lower ends pto a weight lb. The other ends of the cables are connected as shown at 49 to the lower ends of the legs :25 of the movable carriage. It will be noted that a shaft 45, a pair of grooved wheels 46 and movable weight 48 are located upon opposite sides of the scoring machine.

p The rack 20 is secured by means of an angle bar 50 to the cross bars 26 connected to the legs 25 of the movable carriage. A pair of spaced guides 51 are secured to the transverse bars 14 and adapted to receive and guide a block of ice through the scoring machine when said block ot ice is riding upon rollers ofthe track 2.

It will be seen from Figure 2 that the legs 25 of the movable carriage are inserted within the vertical hollow guides 12 pro- \iding a hearing for the legs 25 of the 1novable carriage for guiding the movable car riage vertically when the same is operated.

A. block 5- is secured to one .of' the posts 4 adjacent the discharge end of the scoring machine upon which are pivotally mounted in spaced relation a pair of rods or stops 54 and The outer free ends of the rods are movable in slots formed in a plate 56, which is secured to an opposite standard 4 of the rigid t'rame. Rod 51- is connected by means of a link 57 to an operating pedal 58 while rod is connected by means of a link 59 to an o erating pedal (30. These rods are. adapted, when moved in the position shown by the position of the bar 55 in Figure 2, to maintain the block of ice against movement during the vertical scoring.

Referring more particularly to Figure 3 it will be seen that. the vertical shafts 43 are mounted in U-shaped casings (it which are Sll1)1')(.)lt0(,l on the stationary frame by means ot clamps 62. A coil spring 64 is located on each of the shafts 43 between a pulley 4:2 and a block (35 carried by the upper end of each of the casings (S1. Brackets 66 connected with the transverserods 7 of the stationary frame are connected with the upper ends of the casings (it for aiding in' supporting the same rigidly with resp ct to the stationary frame.

liars (57 have. their inner ends secured to the table 21 aiid have their outer ends provided with rollers 68 adapted to engage the shaft housings 61 when the carriage is moved tor scormg purposes.

The operation of our device is as follows;

wardly. \Vhen the table has been moved to its most elevated position the cone pulleys 41 will be moved into engagement with the cone pulleys 42. The springs 70 mounted upon the upper end of the shaft 433 permit the pulleys 42 a slight upward movement and the springs cushion the shocks of the engagement of the pulleys 41 with the pulleys 42. The motor 22 may bein operation or the current may be turned on to operate the motor and since the pulleys 42 are rotated through connection with the motor the pulleys 41 are likewise rotated, revolving shaft 43 and the cutters 44. As the block of ice 52 is moved through the scoring machine the cutters 4A produce a horizontal cut 71.

The block of ice 52 is maintained within a predetermined position within the scoring machine by either of the stops 54 or 55, it being only necessary to depress either of the foot pedals 58 or 60 to lower either of said rods for restricting movement of the block of ice. The block of ice is held by stop 55 to produce the scoring shown in Figure 5. In order to vary such scoring the block thus scored is released by stop 55 and removed to stop 5- and retained thereby after the cutters have been operated. lVhen the cutters are operatively lowered other scorings will be produced on said blocks spaced from the previous scoring. It must be borne in mind that the stops 54 and 55 are so spaced in actual practice. that they will produce cuts or scorings so spaced that they will represent a definite number of pounds which are less than the number of pounds designated by the scorings on the blocks of ice when said ice has been held by stop 55. As soon as the block of ice is positioned within the scoring machine the hand wheel 17 is released and the movable carriage through its own weight and against the resistance of the weight. 48, will descend slowly and since the motor drives the cutters 31 through the belts 3:2, the cutters 31 will produce the vertical scores 72.

It will be seen from Figure 5 that the block of ice normally is so scored that six smaller blocks of 50 pounds each will be provided for. Other scores may be produced by a different arrangement of the position of the block of ice in the scorii g machine. As soon as th carriage begins to. descend the pulleys 41 will be moved out of engagement with the pulleys 42 and the horizontal scoring cutters 44 will remain inactive.
