This invention relates to an ice' scoring'machine, as described? in the present specification and illustrated in the accompanying drawings which form part of same.

The invention consists essentially of the novel: features pointed out broadly'and spe cifically in the claims for novelty following a description containing an explanation in detail of an acceptableform of the inveni.

The objects of the invention are to build an ice scoring machine of simple,-durable and economical construction; to effect all 'aossible economy ofspace by making avery compactand complete machine; to make the operation in such a machine as simple and reliable as possible; and generally, to improve upon existing'icescoring' machines.

In the drawings, Figure 1 is a'front elevation of the machine.

Figure 2 is a section on line 2"2 in. Figure 1. v g I I Figure 3 is a fragmentary side elevation of the sprocket chain showing the special-link and bridge.

Figure i is a top plan view of'Figure 3.

Figure 5 is a fragmentary view showing the ice block feeding or shifting means.

Like numerals of reference indicate corre sponding parts in the various figures.

Referring to the drawings, 10- is the frame of the machine; the frame is madc'of two end upright members 11, preferably castings, rigidly secured in their spaced lrelation'by spacers '12. and 18, and by the longitudinal members or beams 14: which are positionedin the axis of the machine. 17 17 and 18 are sprockets rotating in the end members 11, each of the sprock-ets 17 rotating with the gear 19' meshing with the gear 20 rigidly mounted on the horizontally-arranged shaft 21: the shaft 21 rotates in suitable bearings 21*. 22 are sprocket chainswound around,

the sprockets, as best shown in Figures 1 and 2; the sprockets are'dlsposed in a rectangular arrangement, as best shown in Figure 2. so that the sprocket chains travel in a substantially rectangular path.

23 is a motor mounted on th-e'bracket 24 and rotating the horizontally-arranged shaft 25, on one endof which is rigidly mounted the pulley 26. 27 is a pulley rigidly mounted on one end of theshaft 21;, and 28 is a belt wound around the pulleys 27 and 26. '29 are the scoring saws or elements rigidly n ountecl' on tli shaft in. any Suitable way.

By operating the motor, the saws are rotated, thesliaft 21 also rotated, turning the gears and the sprockets 17 and therefore propelling the sprocket chains 22 man endless course or path around the sprockets.

Pivotally suspended from the sprocket chainsQQ' are the elevators, cradles or carriers 30 by which the ice block is carried; each elevator rises vertically to bring one face of the block in contact with the revolving saws, thus scoring that face, and later descends to bringthe opposite or unscored face of the block in contact with the saws to.

score the last-mentioned,face of-sa-id block; The elevator is formed substantially as shown, having the spaced longitudinally-arranged members 31 secu-redto the-tension members or supporting arms 32 bymeans of the bolts 32. Each ofthe arms 32 is formed withsuitable eye 33topivotal'ly connect the armto the stud or pin 34 of the sprocket chain, specially-formed link 35'.

The link'35 rigidly carries the bridge member 36' which is approximately twice as long the distance between the upper sprockets 17 and 17 thus forming a bridge between these sprockets and, taking the load or weight of the: elevator and ice off the chains when the links 35 are in any position between sprockets, or in other words, when the elevator' is travelling horizontally between the sprockets 17] and 17 37 are cross members rigidly carried by the members 31 and spaced at a distance less than thel'ength of the ice block; near each end of the cross members are sharp pins or points, 38, forming 'supports for the ice, and therefore digging into the ice block and preventing it from slipping.

The elevators are disposed along the chains so as to balance, as much as possible, the weight of one with that of the other.

40 are; bars vertically arranged by bolting same to the bars 12",ancl 13at a distance apart less than the length of the block of ice,

these bars formingslides or guides for the block as it travels upwardly and downwardl, durin the scoring 6 eration or in other words, constraining the movement of the block during scoring to two planes parallel, with the chains 2'2.

: 411 are af pairv ofu shaped irons suitably secured to the beamslhforming stops checkmg the motion ofthe, ice block as it is pushed or fed'into the machine rior to scoring, and I a f rm ng g des wit the guides t0,

46 are horizontallyarranged bars bolted to the U-irons 41 and laid at right angles to the axis of the machine, one end of the bars being -bent downwardly and inwardly as at 47; 43 is a plate supported by the angle irons 42 which are secured to the end castings 11 of the frame 10, this plate forn'iing a table for the ice block as it is slid endwise into the feeding position, and also forming with the bars 46 the means ofsupporting the block before it is engaged andlifted by the rising cradle 30 forthe first scoring operation. The plate 43 and bars 46 are spaced from one another to provide a clearance 48 for the passage of the bars ill of the cradle 30. Bars 5-.l.haing the turned down ends 54 are carried by the floor and spaced opposite the bars 46, thus guiding the cradle bars 31 into the clearance 48. An angle 44 having the turned out end is preferably provided on the plate or table 43, so as to guide the ice when slid into feeding position in front of the machine; 50 is a suitable stop for arresting the motion of the block when pushed in over the table, this stop also determining the position of the block from which. it is to be fed into the machine.

53 is a suitable table secured to the frame. as with angles 55; a suitable slide is provided to elevate the block from the cradle, after scoring, and allowing it to slide down onto the table 53, this slide and table forming the ice delivery means of themachine. The slide may be formed with metal-shod wooden wedge-shaped blocks 56 and 57 secured to the bars 46 and plate 53, respectively, these blocks being spaced to provide a clear ance 58 for the passage of the cradle bars 31 as the cradle travels downwardly. 51 and 52 are guide bars vertically arranged and secured in position in any suitable way; in the drawings, the bars 51 are shown bolted to the cross bar 51 which is rigidly secured to one of the beams 14, 60 being an angle brace securing the lower ends of the bars 51 to the longitudinally-arranged bar 61 carried by the U-bar 41; the guide bars 52 are shown secured to cleats 62 carried by the braces 13 and also suitably fastened at the beyond the angle 44 of the table 43, slots 68 being provided through the angle 44 to form a passage for the ends of the arms as these are swung outwardly into operative position; the operative position of the arms 67 or lever 63, is determined by the engagement of the arms with the angle 44, or in any other suitable way.

recesses As the chains describe a substantially reetangular path, rising and loweringin vertical parallel planes, it follows that the clearances 4S and 58 must be verticallybelow the pivotal point of the cradle on the chain.

Operation: As already explained, the operation of the motor rotates the saws 29 while rotatingthc shaft 21 and propelling the chains 22. As the chains are'propelled, in the direction of the arrow (Figure 2), the cradle describes a rectangular path. The iniscored ice block is pushed upon the table 43, sliding against the angle 44 until it is arrested by the stop 50. The lever 63 is then pulled away from the machine. the arms 67 slidahly engaging one face of the block and sliding same over thetable 43 and onto'the bars 46 until it comes in contact with the irons 41. The block is now in a position to be engaged or lifted by the cradle as it travels up through the passage 48. One face of the block is scored as the cradle travels upwardly; as the cradle travels horizontally between the sprockets 17 and 17", the bridges 36 take the weight ofthe cradle and ice. off the chains and transfer same to the sprockets; as the cradle descends, the other or unscored face of the block is scored, and as the cradle passes through the. clearance 58, the block becomes supported by the slide and tinally slides out of the machine onto the ta.- ble 53. I i

If thetables 43 and are made level with the floor, a trough is made into'the floor below the machine frame to provideclearance for the passage of the cradle as it swings under the machine.

It is to be understood that the invention is not confined to the particular construction shown. nor to the use of two cradles. Similarly, the invention is not confined to the use of a table 53, or of a table 43, since the ice could be slid over the floor and into the machine and discharged at the delivery side onto the floor.
