Application le. November 17, 19255. Serial No. .69,689.1v
My invention a relates to power Y driven saws especially adapted for use by butchers-in cutting the bones occurring in meat.
Therprincipalrobject of' my invention is to provide a simple'l and easily portable power driven saw; to takethe place ofl the usual hand' saws'vcommonlylus'ed by butchers. rA asaw which ring: the oth-erfree;toghold: the Work inthe same manner as isfdone whenusing a hand saw: Astill furtherxobject. is to.v providev suitable guards for the saw,A suchguards `having the. double function ofproviding a rest' to steady the saw andj'off inclosing Ato .prevent bone; chipsA troni' getting upon and into: the meat, and 'tof preventV the sawfrom cuttinginto f or tearing: the meat.. rlhe guards also 'protect .the operator: -from injury through contactwithy thesaw. i
These and other.obfectsxandx advantages of: the .invention will be.v apparent;.-,fronr the following speci lication, which shouldy be 1 rea-d with theunderst-anding that the'` form, proandarrangement ofthe several parts of' the: devicemay; be-varied, within the limits'o the claims. hereto appended, without departing` from the spirit of the invention.. ask expressedin said claims@l It is alsot to be understood although v'especially' adapted: for .Inea saws, may beembodied'in saws for other` purposes, without-'material' change.- f `With this in view a preferred embodiment/of: myinvention will now be described fully with reference to t-he accompanying drawings, whereinvzf# f Fig, 1 is a partly broken 'front elevation kof myv meat saw.l
Fig is a1 centrallvertlical section-tl'iei'eof, the driving motor andcable being:V shownin elevation.
Eig isa plan View, themotor and; drive shaft being omittedr lnj the drawings, the vreterence numeral 1 designates -a' circular saw, which issecured, as by means of screwsy 1", Fig;-1tora hub-2, and said hub` is fixed'upon orl for-.medi integrally with a. shaft 3, Fig.
ably mounted in a journali members. This .Eig 1.

proximate ycenter of saidplate.
The plate 8 formstheback otra-guard or .housing forthe saw 1,1 the:l front off' said housing: beingv formed: byl a; secondqxplate 9 which; isfconnected` with said bac'kplate 8 at. its top, asi shown at 10, and abouthalf way- 1down-itssides, as. indicated atv 11 in l The lower portionsv of' thepplates 8; and@ are separated by a narrow space 12, lig;. 2;just wide 'eiioughftozallow the saw 1 .to protrude. through it; when said saw .is ymoved downwardly in; the guideslot 7j, as
shown by dottedilinesiin Fig; 1. .The yplates 8. andl 9:1 are inclin'edV withf respect .to each other, as; show-ny iniFigzQ, their lower` portions being. clbsely adjacent .toA the. sides` of the saw,andl their: upperportions being spaced therefrom.l Af segmental flange; or rim,l 8f may loe-'secured tothe lower portion of, the-plate 8,. as shown in Fig-2.
y They journal member 4r is norinallypietained; at.` thefupper` limit off its. travelvin the slot 7 byanUeshapedispringgl; Figs-1 andf, oney endot` which'is connected with a pin 14 secured to. the top; of' said journal member,
1and-the.4 otherend' connected with.` apin 15 projecting `from the back plate;v 8. :Handle portionsv 16 are preferably formed upon,- the twoyl'egszof the spring; 13, by whichzit may bef grasped conveniently --iiiz` one" hand vfrs a:*preiferred'` means" for drivingV the saw. l, I have slio'wirI invFig.. 2 a portable 'motor 17, connected with the shaft' 3 by'av flexible di'ive'shat or cable 18:of well known form; The motor 17Iv may bel supported in any; desiredffinanner. For eXa-mple, .I Vhave shown 'itas providedy with :a-.strap or loop- 19 slungy `lover- .thef armi or shou'lder'- of the operator,y or-liungupon any other,l convenient 'support-iy A switchis injdicafted at QO for controllingi; the-motor- It ispintendedthat devicewill be used, in #inea-tl v cuttinggexactly as the Abutchers hand lsaw isf used;- at present; i.` e'. the meat itself will be cut with a knifedown to and around the bone, and my saw then used for cutting through vthe bone. This is illustrated in vli`ig-2, where 21 designates the uncut portion of themeat, 22 is the bone, and
The operator, holdingmy device .in one hand by'grasping th'ehandle portions 16 of the spring`18, rests the lower edges ofthe plates 8 and 9 upon the top of the bone 22 between the uncut portion21 and the partially cut slice 23, the front plate 9 resting againstsaid uncut portion, and then, by compressing o rV squeezing together-the handles 16, moves the Y saw 1 downwardly against and through the'-bone,`the housing vformed by the plates 8 and 9 remaining in its originalpositionwith its bottom edge resting upon the bone.' Vhen thejsaw has passed through the bone,.the spring 13 returns Qit upwardly to its original position lin whichit is f ully inclosed by" said housing. g By making the plate 9 andthe bottom flange 8 of the plate `8 of very thin, vstiff metal, such as hard steel, the thickness of thee-ntire lower edge 'of thedevice is small enough to allow it -to rest'upon'the bone at the bottom ofthe knife cut, and the thinness of said plate 9 also enables the. saw to cut the bone so clo'sejto the planefof the cut surface of the meat that therenis no appreciable difference. "The inclined? relation of the plates 8 and r9 permits ample clearance for the hub 2 and thefupperportionof the saw, besides 'ad'dingt'o thef'stiffness ofthe housing. Moreover, the inclining of the front plate`9 with respect to the saw causes said saw to undercut at a slight, angle, so that at the lower sidefof the bone the cut surface thereof will .not protrudebeyond'the meat by even so and.' their top edges being more widely A 1.' Ar sawing device oomprisingarotating saw; a housing therefor form'edof a pair of spaced plates between which the saw is po-v sitioned, thev bottom edges of said plates lying closely adjacent to the sides of the saw and being adapted' to rest upon the work,-
