' To all whom it may consem:

Be it known that I, WILLIikIlI A. SAUN- nilns, a citizen of the United States, residing at Jamaica Plain, in the county of Sufiolk and State of -Massachusetts, have invented new and useful Improvements in Carcass-Splitting Machines, of which the following is a specification.

' This invention relates to improvements in sawing machines and particularly to a machine for sawing or, in other words, splitting carcasses ofhogs or steers, and has for its object to provide a rapid, efficient and'conveniently operated machine for sawchine of this class in which there shall be practically no time lost in the operation of the machine, as would be the case if a s1nthat by employing a plurality of saws act-- ing successively the return motion of the saw which would be necessary with the use of a single saw, is obviated.

To these ends, the invention consists in the novel features of construction and in the. combination and arrangement ofparts set forth in the followingspecification and particularly pointed out in the claims.

Referring, to the drawings: Figure 1 is a plan of a carcass splitting machine em.- bodying my invention. Fig. 2 is a front elevation oftheinachine. Fig. 3 is a side elevation viewed from the right hand, side I of Fig. 2. Fig. 4 is a sectional view taken on line 44 of Fig. 2, looking toward the left. Fig. 5 is anenlargeddetailsectional View of one of the saws and its arbor taken on line 55 of Fig. 2, looking toward the left.

Like numerals refer to like parts throughout the several views of the drawings In the drawings, 5- is a saw carrier whichmay be. mounted to move upon a suitablesupport and which ,is preferably journaled .upon a pair of supports 6 and 7 which are preferably provided, respectively, bosses 8 and 9 projecting into hubs or trun nions .10 and 11, respectively,provided on the saw carrier 5. J ournaled on the saw carrier 5 is a saw or a plurality of saws, preferably the latter, and in the present instance'there are shown twosaws 12 and 13 secured to arbors 14 and 15,.respectively, journaled in suitable bearings on the saw carrier These saws are mounted in one and the same vertical plane so that by rotating the carrier 5. the saws may be caused to operate successively upon the successive carcasses as the same are placed in position to be operated upon. The carcasses may be placed on any suitable support, but for this purpose there is preferably employed a rotating support 16 mounted to rotate about a vertical axis and having a plurality of wings 17 forming compartments 18, so to speak, in which the carcasses may be placed andheld during the splitting operation, one of the carcasses being shown in such position in Figs, 1 and 2. VVhile one of the carcasses is being operated upon by the saw, others may be hung in the next succeeding compartment 18 of the rotating support 16 ready to be brought with preferably into position to be operated upon by the saws simply by rotating the support 16 the required'distance.

In order that the rotating support may be firmly held against rotation during the splitting operation, there is preferably. em-

ployed' a means to lock the same in a series of predetermined positions, such means preferably consisting of a locking plate 19 provided with a series of notches '20 corresponding in number 'to the compartments 18, which notches are arranged to receive a locking key 21 provided on a lever 22; The,

lever 22 is mounted on a pivot 23 on a suit-' able support 24 and is so arranged that by. lifting the outer end of said lever the key 21 may be withdrawn from the particular .notch 20 in which it islocated, thus permitting the holder 16 to be rotated the required amount and locked.

The saws 12 and 13 are driven by any suitable nieans such, for example, as belts 25 and 26, respectively, passing around pulleys 27 and 28 secured to the arbors 14 and 15, respectively, said belts being driven by pulleys 29 and 30,. respectively, secured to a driving shaft 31 journaled in suitable bear;

34 is journaled concentric wit-h the axis of the supports 6 and 7 and the idler pulley so arranged with relation to the idler pulley 34 that a substantially uniform tension of the belt 32 is maintained during the swinging of the supports 6 and 7 to and fro.

A rotary motion is imparted to the carrier 5 by suitable means preferably consisting a worm gear 39 secured to the hub 10 of said carrier and meshing with a worm 40 secured to a shaft 41 journa-led in suit able bearings on the support 6, said shaft being'preferably driven from the driving shaft3l by suitable driving connect-ions preferably consisting of a belt 42 passing around a pulley 43 secured to the shaft 31, around two idler pulleys 44 and 45 journaled on the support 6, and around a pulley 46 secured to the worm shaft 41.

It will be understood that by the mechanism just described be rotated at a' high rate of speed and the carrier 5 may be revolved slowly by the use of the worm and worm gear driven by the driving shaft 31 so that the saws are brought successively, into operation by the rotation of the carrier the arrow a, Fig. 2.

The supports 6 and 7 are preferably mounted in such a manner as toenable the operator to move the same laterally so as ally supported upon a frame 47 mental gears 54 an to changethe path of the saw from the circular path which it would otherwise have to a path which .will'follow the shape of the backbone of the carcass and for the supports 6 and 7 are preferably pivothaving two side members 48 and 49. Preferably the side members 48 and 49 are provided, respectively, with bosses 50 and 51 constituting pivots projecting into hubs 52 and .53, respectively, provided on the side members 48 and 49,

Suitable means are provided for moving the supports 6 and 7 laterally'during the operation of the saws. and for this purpose there is preferably 55 secured to said supports,- respeotively, and meshing into pinions 56 and 57, respectively, secured to shafts 58 and 59, respectively, jounraled in suitable bearings on the side members 48 and 49-of the frame'47. In order that the pinioins 56 and 57 maybe driven'in unison, I provide suitable driving connections between the the saws 12 and 13 may" 5 in the direction of.

' carcass into the this purpose.

. of the rotary rovided a pair of segshafts 58 and 59 and in the present instance for this purpose, I provide a shaft 60- journaled in the side members 48 and 49 and passing through the bosses. 50 and 51, this shaft being connected to the shafts 58 and 59 by suitable gearingprefera-bly consisting of two miter gears 61and 62 secured to the shaft 60 and meshing with miter gears 63 and 64, respectively. The gears 63 and 64 are secured to vertical shafts 65- and 66, respectively, journaled on the side members 48 and 49 and having secured thereto at their upper ends miter gears 67 and 68 meshing with miter gears 69 and 70 secured to the shafts 58 and 59, respectively.

Secured to the shaft 58 is a suitable hand wheel 71 conveniently arranged so that the operator may stand in a convenient position to view the action of the saws upon the carcass and may control the path of each saw by rotating said hand wheel in the proper direction, thus swinging the supports 6 and 7 to and fro according to the path which it is desired the saw shall take. The lateral movement of the supports 6 and 7 is limited y a pair of studs 72 and 73 secured to said supports, respectively, and projecting through slots 74 and 75 provided in the side members 48 and 49, said studs also serving to prevent any lateral springing of the supports 6 and 7, as will be evident by an inspection of Fig. 4.

Having specifically described the I will now operation.

The carcass to be split isplaced in one of the compartments of the rotatable supports 16 and said support is rotated to bring the proper position to be operated upon by one of the saws. While this positioning of the carcass is taking place, it will be understood that the saw carrier 5 is proceed to despribe its general in a vertical or nearly vertical position so that by the time the carcass has been properly positioned ready to be operated upon,

one of the saws will swing'around into such a position that the operator may cause it to begin its cutting operation by manipulating the hand wheel so as to advance the saw into the Work and as the saw descends by reason motion of the carrier 5, the hand wheel is manipulated in the proper manner to carry the saw into ,the correct path to:-'cut through the backbone of the carcass. By the time that this has taken place, the saw has descended pretty well. toward the floor and while the motion of the saw carrier continues the rotatable support 16 is rotated a partial rotation, bringing another carcass previously placed in the machine, 1

next succeeding compartment into the proper position to be operated upon by the-next saw in the same manner in which the previous carcass was operated upon by the other saw.

Havingthus' described my invention,

to secure is:
