STATES raiser HARVEY C. MASLAND, OF ?HILADELPI IIA, PENNSYLVANIA.
SURGICAL SAW Application filed April 26, 1922.
To all LU/Z0772, it may concern:
Be it known that I, HARVEY C. MnsLANn, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Surgical Saw, of which the following is a specification.
My invention consists of a surgical saw embodying a rotatable member which is adapted to be operated by a suitable shaft in the handle of-the device, and a sliding member engageable with said rotatable member adapted to receive therefrom reciprocating motions which latter are imparted to a saw or saw blade which is at tached suitably with said sliding member.
It consists also of details of construction as will be hereinafter set forth.
The invention is satisfactorily illustrated in the accompanying.drawing, but the important instrumentalities thereof. may be varied, and so it is to beunderstood that, the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the invention.
Figure 1 represents a partial side elevation and partial longitudinal section of a surgical saw embodying my invention.
Figure 2 represents a transverse section on line 2-2 Figure 1.
Figure 3 represents a side elevation of a detached member of they device.
Figure 1- represents a longitudinal section of the member shown in Figure 3.
Figure 5 represents a transverse section of a portion on line 55 Figure 1.
Figure 6 represents a transverse section on line 66 Figure 1.
Figure 7 represents a transverse section on line 7-7 Figure 1, on an enlarged scale.
Figure 8 represents a longitudinal section of another embodiment of the invention as a preferred form thereof.
Figure 9 represents a view of a portion of Figure 8 on an enlarged scale.
Figure 10 represents a longitudinal section of the stock shown in Figure 8, as removed therefrom.
Figure 11 represents a transverse section on line 1111 Figure 8.
Figure 12 represents atransverse section of a modification of the construction shown in Figure 11.
Similar numerals of reference indicate corresponding parts in the figures.
Serial No. 556,684.
Referring to the drawings.
tool, the same having therein a bore 2 in which is mounted the driving shaft 3 which is adapted to receive power from any suitable source by means say of a flexible shaft not necessarily shown.
To the forward end of the shaft 8 is screwed or otherwise secured the cylindrical shaped stock 41 which is adapted to be rotated by said shaft, said stock having in its periphery the spiral groove 5 which extends continuously around' the same.
Freely surrounding said stock is the sleeve 6 to whose forward end is secured the longitudinally extending yoke 7 whose legs 8 and crown 9 freely encircle the portions of the stock forward of said sleeve. 7
To the rear end of said stock are the longitudinally extending legs 10 which are litted freelyin longitudinally extending openilngs 11 in the forward portion of the han- Connected with the sleeve 6by the screw 12 is the roller 13 which latter occupies a position on the inner circumference of said sleeve and enters freely the spiral groove 5 of the stock 1, the shank of said screw forming the bearings for said roller.
Connected with the crown 9 of the yoke 7 is the arm 1% to which is attached the saw 15,said arm and heel end of the saw being encircled by the clamp 16 which is provided with the set screwl17, the latter being adapted to tighten against the adjacent face of said arm, whereby the saw is firmly secured in position on said arm and consequently on the yoke 7.
The stock .4- has on its terminal the milled rim. 18 whereby said stock may be conveniently tightly screwed to the operating shaft in assembling parts of the device, and con veniently unscrewed therefrom in disassembling said parts.
Figures 8, 9, 11 and 12 show a preferred form of my invention. In this case the arm 14 is connected with the front wall of a cylinder 19 on whose inner circiunference is the roller 13 which is mounted on the screw stud 20 which in Figures 8, 9 and 10 is at the top of said cylinder, while in Figure 12, said roller is carried by a similar stud 20 at'the bottom of said cylinder.
To the lower side of said cylinder 19 is connected the dovetailed neck 21 which is slidably fitted in the dovetailed groove 21 in the upper; side of the bracket 22, the latter being connected with the side of the handle by the screw 22* and extends forward therefrom beneath the cylinder 19 and assists to sustain the, same. In this construction, the milled rim 18 is on the rear end of the stock 4 for the same purpose as hereinbefore described. V
The operation isl' as follows 7 Power is applied to the shaft 3 and trans mitted to the stock 4:, whereby the latter is rotated. Owing to the spiral groove 5 and roller 13 therein longitudinal sliding motions are imparted by said stock to said roller to the sleeve 6 and yoke 7, and consequently to the saw, the latter thus receiving its reciprocations. The legs 10 carried by the sleeve 6 move in and out of the openings 11 in the handle 1, while being supported thereon and thus the saw is operated true. The same result is produced by the cylinder 19 which receives longitudinally sliding motionsby means of the rotary stock 4 through the media of the spiral groove 5 in said stock, and the roller 13- on the cylinder, the latter being guided in its motions by the bracket 22.
I In assembling the instrument, the stock is screwed on the driving shaft until the legs 10 properlyoccupy the openings 11 and the stock is tightly screwed to the drivin shaft or where the cylinder 19 is employe Letters Patent, is
the stock is screwed tightly on the driving shaft and said cylinder adjusted on the bracket, the latter being properly seated on the handle and secured thereto by the screw 22*. c
Having thus described my invention what I claim as new and desire to secure by 1. A devicetof the character stated comprising in combination, a handle, a driven shaft arranged axially thereof and projected forwardly therefrom which projected end is screw-threaded, a stock adjustably fitted to said screw-threaded portion, which stock is provided witha cam-groove, a mem: ber provided with a roller for cooperative relation with said cam-groove, an arm fixed to said member, a clamp fitted over said 2. A device of the character stated Coin,- v

Y 7 I j 3. A device of the character stated comprising in combination, a handle,a driven shaft arranged axially thereof and projected forwardly therefrom which projected end is screw-threaded, a stock adjustably fitted to said screw-threaded portion, which stock is provided with a cam-groove, a member provided with a roller for cooperative relation with said cam-groovaan' arm fixed to said member, a clamp: having a squared opening fitted over said arm, a saw fitted within said clamp and against said arm,
end a set-screw for securing said clamp, arm and saw in fixed relat1on.
