SAFETY-RAZOR To all lwhom it may concern.'
Be it known that I, JOHN BRUECKER, a citizen of the United States,l residing at Fort Wayne, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare that the following is a full, clear,.and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to improvements in safety razors. v
It is well known that the safety razors now in use are liable to cut the face of the operator in use, and frequently do so when operated by a lack of care or a want of skill.
The object of my present invention is to provide a safety razor of simple construction, convenient and reliable in use and having its cutting mechanism so arranged as to make any cutting of the face therewith impossible under ordinary conditions.
My invention consists of a barrel or cylinder containing in its forward end the cutting mechanism and connected at its rear end with a suitable water wheel or pump driven by any suitable motive agent.
T e principal novel features of my inven ion reside in the cutting or shaving mechanism and the coperating safety mechanism.
Similar reference numerals refer to similar parts throughout the several views of the drawing in which- Figure 1 is a plan or front end view showing in dotted outline the relative arrangement of the discharge from the pump, the means for safe guarding the cutting mechanism and the means for securing the same in position. Fig. 2 is a plan view of the detachable plate having a series of vertical openings through which the beard is drawn by suction into the path of the cuttin mechanism. Fig. 3 is an enlarged detail plan of the rotary cutting mechanism. Fig. 4 is a view in elevation of my invention partly in vertical section to show the relative arrangement of the cutting mechanism and its coperating parts. Fig. 5 is a fragmentary transverse section of the upper end of the barrel with the guard plate in position therein. Fig. 6 is a side view of Fig. 3. Fig. 7 is an enlarged detail of the inlet wa- Specification of Letters Patent.

ter valve having` a suitable pressure' gage thereon. F 1g. 8 1s an enlarged fragmentary view of the means for securing the safety plate in position. Fig. 9 is a vertical central section of the same. Fig. 10 is a longitudinal section of Fig. 7. Fig. llis a detail of the meansfor securing the plate shown in Figs. 8 and 1 in position. Fig. 12 is a plan view of the pump; and Fig. 13 is a transverse section of the same. Fig. 14 is-a detail plan of the valve for regulating the quantity of water to be admitted into the barrel. Fig. 15 is a side elevation of Fig. 14
partly in vertical section.
Referring for the present to Fig. 4 the barrel' 1 of suitable dimensions and open at radial discharge channels 9 opening into the main discharge passage 6.
A vertical driving shaft 10 has the water wheel 7 secured thereon. To the protruding lower end of the shaft 10 which has a bearing in the screw-plug l2 is connected in any suitable manner an electric motor or other actuating means. The upper end of the shaft 10 passes loosely through a central opening in the annular plate 13 which is fixed to the sides of the barrel 1 and has a plurality of vertical openings 14 for the passage of the pump actuating jet of water. On the upper end of the shaft 10 is 'snugly mounted the cylinder l5 having a diametric longitudinal slot 16 in its lower 'end and having its closed upper end provided with a plurality of fixed or integral radial cutting blades 17, Figs. 3, 4 and 6, preferably 3 in number. described is secured against rotation on its shaft by the pin 18 which passes through the shaft 10 and the slot 16.
The upper end of the barrel '1 is closed by the safety plate 18 which has a series of vertical openings 19 whose outer edges are beveled as shown and one-half of whose perimeter is beveled as shown at 20 and is adapted to snugly fit within a coperating semiannular recess in the inner face of the barrel 1 as shown at 21 in Fig. 5. The other portion of the perimeter of the plate 18 being adapted to rest upon the upper edge of the barrel and having a beveled section 22 to be The cutting mechanism thus los engaged by a lip on the retaining plate hereafter described.
The barrel 1 at a suitable point near its upper end and below the plate 13 has a radial opening into which is fixed a lateral pocket 23 in which is fixed an externally protruding spring catch consisting of two or more sections 24 adapted to be temporarily compressed but whichare normally spread apart as shown to form a holding engagement.
A curved plate 25 having upon its upper end and inner edge a lip 26 adapted to'engage the beveled face 22 of the plate 18 and provided with a lateral opening in which is fixed a thimble 27, Figs. 8 and 9 having an annular shoulder 28 adapted to engage the catch sections 24, is adapted when placed in position on the barrel to firmly secure the safety plate 18 in position against any possibility of derangement in use, as the shoulder 28 engages the catch sections 24.
At any suitable point in the side of the barrel 1 and forward of the plate 13 is a lateral opening having a centrally apertured concave disk 29 fixed therein in which disk is fixed the inner end of a tube 30 having mounted therein a plunger 31 provided upon its inner end with a ball valve 32 secured against displacement by the hood 33 and normally held to its seat by the spring 34. The tube 30 has a lateral opening in which is arranged any suitable pressure gage 35 of Well understood construction, Figs. 7 and 10.
lrVater is supplied to the pipe 30 by means of the pipe 36 from any suitable source of supply. The pipe 36 is rigidly secured in position by the clip 37. At a suitable point on the pipe 36 is arranged a regulating valve 38 having a thumb-nut 39 and a. radial pin 40 adapted to slide freely in a curved slot 41 in the valve casing 42, to limit the rotary movement of the valve in its seat. The valve 38 has a diametric opening 43 vadapted to register with the longitudinal opening 44 in the valve casing where the valve is open in the usual manner. The pin 40 also enables the operator to see at a glance the extent to which the valve is opened at any time.
The operation of my invention thus described briefly stated is as follows: When the shaft 10 is rotated by any motive agent y'water of the interior of the barrel 1 and consequently upon the surface of the skin when placed ,in Contact With the outer face of the plate 18', thereby automatically drawing the short hairs upon the surface of the skin through the openings` 19 and into the path of the'revolving blades 17 of the out# tingmechanism, whereby they are safely -cut off Without any danger of contact of the blades with the skin. The beveled upperl edges of the openings 19 are adapted to receive by suction the skin of the face and thereby facilitate reception of the Qhair by the openings 19.
The blades 17 are slightly inclined to the axis of the head 15 as shown in Fig. 6, and their upper edges are firmly held in Contact with the inner face of the plate 18 by means of the coiled spring 45 which is mounted within the head 15 and on the shaft 10 and bears at its lower end on the pin 18 whereby the blades are self sharpening in ya well understood manner. The openings 19 in 'the plate 18 have their sides beveled as shown in Fig. 2 to facilitate the suction action upon the surface of the skin to be operated upon.
Having thus described my invention and the manner of operating the same what I desire to secure by Letters Patent is:
In ai device of the class described, a barrel; a safety-plate removably attached upon the top of the barrel and having numerous circular openings therein, each of which is eccentrically counter-sunk upon the exterior side of the plate; a rotary cutting memberl bearing against the safety-plate upon the inner side thereof; mean.; to drive the rotary member and a mechanism for creating suction within the barrel, there being an inlet leading into the upper Dart of the barrel.
