A llonley Patented Oct. 27,V 1931 UNITED STATES JAMES A. YOUNG .AND FRED BRYAN, OF SCIO, OREGON MEAT vSAW f Application filed June 17,

The present invention relates to a meatsaw and has for its prime object to provide a power driven saw in this nature which is eX- ceedingly simple in its construction, light,

5 strong and durable, compact and convenient in its arrangement of parts, easy to manipulate, thoroughly efiicient and reliable in use and operation, easy to assemble and disassemble and saw blade from the remaining portion l1`0 of the mechanism, and otherwise well adapt- 20 saw structure embodyingthe features of our invention,

Figure 2 is a sectional view through one end thereof, I

Figure 3 is a detail section taken substan- .25 tially on the line 3 3 of Figure 2,

Figure 4 is a perspective View of one of the saw blade attaching blocks.

Figure 5 is a transverse section taken substantially on the line 5-5 of Figure 1,

Figure 6 is a similar view taken substantially on the line 6-6 of Figure 1, and

Figure 7 is a perspective view of the externally screw threaded sleeve to which one end of the cable is attached.

Referring to the drawings in detail it will be seenthat the letter F denotes generally an elongated frame which in the present instance this frame F comprises an elongated straight hollow upper rail 5 which merges at 40 its ends into arcuate channel end rails 6 which in turn merge into bottom rail segments 7 terminating in spaced relation to each other and of channel construction having inwardly directed flanges 8.

Braces 9 extend between the terminals of 193.0. Serialf No. 461,770.

the sections 7 and intermedia-te portions of f the rail 5. A housing 10 is formed on oneend portion of the rail 5 and has a double spiral grooved rotor 11 journalled therein with an extension l2' adapted to be connected to a 50 power driven cable shaft or the like.' Afblock 14 is slidable insaid end` portionfof the rail 5l and has afpin 15 projecting into the groove of the rotor 11 so that when the rotor 11 is mption the block 14 reciprocatessbackand .55 ort f Cables 16a are connected with the block'14 and trained over. keys or pulleys ljournalled lin the end rails 6 as clearly illustrated in- Figure 2. On-,the ends of the cables are externally threaded sleeves 18 adapted to bere'- ceived in blocks 19 mountedfor reciprocation in the rail sections 7.

These` blocks 19 have reduced extensions 20 from the ends of which rise spaced panal. lel ears 21. rBlocks 22 have reduced ends split to form spaced,parallely furcations. 23 yhaving notches 24 in intermediate portions of their upper edges.y The reduced portion 23 is pivotally mounted as at 25 betweenthe ears 2,1 and ,theblock 22 is adapted t-o be locked ony the portion 20 by a screw 26. Numeral27 denotes a meat saw blade, the ends of whichv have laterally extending `pins 28 to be received in the notches 24 and then W the blocks 23 are swun-gdownwardly and locked on the reduced portions 20' and. the sawy is ready for operation causing recipro-k cation back and forth of the saw blade..l

A bowed spring 30 is anchored as at 31 Re on: one end rail 6 andprojects through one brace 9y and terminates in. abutment with the upper edge of the saw blade 27. y

It is thought that the construction, operation, utility and advantagesof this inven- Si tion. will now be quite apparent to those skilled in this art without a more detailed description thereof.

merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It is apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed 0r sacriicing any of its advantages.

Having thus described our invention, what we claim as new is:

l. A saw structure of the type embodying an elongated frame having an upper hollow elongated straight rail merging at its ends into arcuate end-rail channeled construction which in turn merge into inwardly directed bottom channeled rail sections terminating in spaced relation to each other, a plurality of guide pulleys journalled along the curve of the end rails, cables in the rails trained over the pulleys, a saw between the ends of the cables, and means in the form of a rotor disposed longitudinally upon the upper rail and having a double spiral groove therein for receiving a pin projecting from a block slidably disposed thereunder in the upper rail to which the said cable is secured, whereby to reciprocate a saw blade slidably maintained between the mentioned bottom channeled sections,

2. A saw structure of the type described embodying an elongated frame composed of an upper hollow elongated straight rail hav- Ving at its end arcuate end rails of channeled construction which in turn merge into inwardly directed bottom channeled rail sections terminating in spaced relation to each other and parallel to the upper rail, a plurality of guide pulleys journalled in the end rails, and spaced apart, cables in the rails trained over the pulleys, a saw between 'the ends of the cables, and means mounted on the upper rail in the form of a rotor having a double spiral groove therein for receiving a pin from a block slidable in the upper rail and under the rotor, having said cables attached thereto whereby to reciprocate the saw.

3. A saw structure of the type described vcomprising a frame consisting of a straight elongated tubular body having on each end a merging dependent outwardly opened arcuate channel, on the lower inward end of which extends inwardly and parallel to the tubular body a tubular bearing extension, a saw blade having a bearing block on each end slidable in one of said tubular eXtensions a plurality of arcuately spaced guide pulleys in each of said arcuate channels, a cable led over the pulleysl in each channel from each of said bearing blocks, and means for 4moving said cables to `reciprocate the saw, comprising, a cylindrical housing In testimony whereof We afiix our signatures.
