ICE KEBFIIN'G OB SCORING MACHINE.

Application filed January 19. 1922. Serial No. 580,888.

To all whom it may Be it known that I, THEODORE A. Sammie- HUHN, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented'a new and useful Ice Kerfing or Scoring .Machine, of which the following is a specification.

This invention relates to ice kerfing machines especially adapted for kerfing or scoring large blocks of artificial ice in order that the same may be easily separated into smaller blocks of predetermine size.

The objects of the invention are to provide a machine of this character adapted to receive the blocks of ice in the standing 0- sition in which.they are usually, hand ed upon the floor and to place the same upon the machine in a fiat position, means being rovided for continuously carrying the block of ice through the machine and kerfing the same longitudinally and transversely upon the upper and lower fiat sides.

Other objects are to rovide a machine of this character which 1s compact and entirely above the floor, occupyinga minimum amount of floor space, bein only sufiiciently high to provide means for erfing the upper surface of the blocks of ice and to provide a single driving means for all of the mechanism.

The above and other objects may be attained by providing a machine as illustrated in the accompanying drawings, in which means are provided for receiving the cakes of ice in an upright position and depositing them upon a conveyer in a flat position, means being rovided for kerfing the upper and lower si es of the cake as it is carried through the machine upon the conveyer, means being provided at the delivery end of the conveyer for delivering the ice upon a second conveyer traveling at right angles to the first conveyer, kerfing means being located adjacent to the second conveyer for kerfing the upper and lower sides ofthe block of ice at right angles to the kerfs first provided therein, the block of ice being deivered' from the machine and deposited u on the floor in the upright position as be ore placing onthe machine.

The invention thus set forth in general terms is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of a machine embodying the invention, the upper portion each of the machine being removed for the purpose of illustration;

Fig. 2, a section on the line 2-2, Fig. 1;

Fig. 5, a section on the line-55, Fig. 1; and i Fig. 6, a section on the line 6-6, Fig. 5.

- Similar numerals of reference indicate corresponding parts throughout the drawings.

The usual block of artificial ice is proportioned as illustrated in the drawings, being comparatively narrow and for the'purpose of convenience in handling, the, blocks are generally placed in an upright position upon the floor in order that they may be easily slid over the floor of the ice house.

The machine embodying this invention is designed to-receive the blocks of ice in this upright position and deposit them upon the conveyer in a flat position in which osition they are carried through the machine, being kerfed both longitudinally and transversely upon the upper and lower flat sides and delivered from the machine in an upright position upon the floor.

Referring to the construction illustrated in the drawin s, the entire machine is car ried upon a ase plate 1 which may be formed of one or more sections, as desired, and which is mounted directly upon the floor and entirely above-floor level. At the loading end of the machine is provided a tiltingl frame comprising a pair of arms 2,

aving the depending, outwardly inclined portion 3 terminating in the horizontal portion 4, these arms being spaced and mounted upon the rockin shaft 5.

. Suitable bearings 6 an 7 are provided for the shaft 5, the bearing 6 being carried by the end frame 8 which is spaced from the adjacent end of the base plate, the bearing 7 being carried b a similar frame 8' located adjacent to the ase plate, a gear segment 9 is fixed upon the shaft 5 and meshes with a similar segment 10 mounted upon the shaft 11 which is journaled in bearings 12 carried by .the frames 8 and 8 and which extends to the forward end of the machine whereit is journaled in the bearin s 13 carried. u on the frame members 14, upli-. cates of rames 8, located at the otherside of the base plate.

The shaft 83 is connected as by the silent drive chain 86 with the shaft 87 journaled in

bearings

88 and 89, mounted upon the base plate. A. sprocket or gear 90 is carried by the shaft 87 and is connected as by the silent drive chain 91 or gearing with the sprocket or gear 92 mounted upon the shaft of the motor 93' which is located upon the base plate. A bevel pinion 94 upon the shaft 87 meshes with the-pinion 49 upon the shaft 46.

Standards 95, similar to the standards 50, are mounted upon the base plate upon opsite sides of the conveyer chains 74. l Bearin 96 are carried in the lower portions 0 these standards and journaled therein is a shaft 97 provided at its inner extremity with a bevel pinion- 98 meshing with the pinion 99 upon the shaft 87. Circular saws 100 are adjustably mounted upon the shaft 97 and arranged to cut transverse kerfs in the under surface of the block of ice as indicated at C in 'Fi 2. Y

The shaft 97 is provide at its outer end with a bevel pinion 101 meshing with a pinion 102 upon the vertical shaft 103, said shaft being journaled in bearings 10% mounted upon the adjacent standard 95. A. bevel pinion 105 is fixed at the upper end of the shaft103 and meshes with the pinion 100 upon the saw shaft 107 which is journaled in bearings 108 providedin the capped portions of the standards 95. Circular saws 109 are adjustablyvmounted upon the shaft 107 and arran ed to cut transverse kerfs in the up er sur ace of the block of ice shown at C in ig. 2.

The 0 eration of the machine is as follows: re erring to Fig. 3, a block of ice as indicated at A is placed upon the rocking frame 4 in an upright POSltIOII; This frame being located close to the floor, it will be seen that the block may; be easily placed thereon in this position, as it is customary to handle the block in an upright position upon the floor.

The frame 4' is then rocked upon the shaft 5 by means of the lever 24:, the arms 18 being thus raised at'their free ends and the block of ice is received thereon from the frame 4, the block being deposited upon the arms 18 in the flat position. The stops 20 will be engaged by the block as it is slid upon thelnclined arms. 18 and when the lever 24 is returned to the normal position, the arms 18 will be lowered tothe position shown in Fig. 3, and the block will rest thereon in the position shown at B in Fig. 3.

As the arms 18 are lowered to the normal position, the block B will rest upon the rollers 16 as best shown in Fig. 2, the forward end of the block bein in proximity to the conveyer 34. The bloc of ice may be easily moved forward upon the rollers 16 until the forward portion thereof is engaged by the conveyer 34, the wood-en blocks 35 thereon frictionallfy engaging the under sur face of the block 0 cc and carrying the same forwardly through the machine and between the

saws

55 and 55, kerfing the block of ice longitudinally to a depth of about two and one-half or three inches.

The block of ice will be deposited upon the rollers 17 as it passes from the conveyer 34 and will be stopped by engagement with the guide 111, assuming the position indicated at C in Figs. 2 and 5.

As each new block of ice is placed upon the receiving end of the machine, the operation of the rocking frame 4 will, through the shaft 11 and the pinion and segment bestillustrated in Fig. 5, move the pusher rods 63 in the direction of the arrow upon Fig. 5,

severing into smaller blocks by the use of' the usual ice hatchet or pick without danger of splitting in uneven sizes.

It will be understood, of course, that any desired arrangement of saws may be provided for kerfing the blocks of ice at different places upon the surfaces thereof in order to cut the same into various sizes of smaller blocks.
