Application filed February 26, 1927.Serial No. 171,090.
This invention relates to a safety razor of the magazine type which is adapted to feed blades from a stack of blades and is of a construction that enables a quick and easy refilling of the magazine, the latter being done by inserting a clip which holds the blades in a stack and is withdrawn when the blades are all expended.
The invention relates particularly to the construction of the parts as will provide, first, a razor of substantially square form in cross-section; second, one that can be easily operated to expel a blade from the magazine into the shaving head; third, providing for a simple and effective means for holding the clip in position and combining therewith a spring to keep the blades in the stack compact and to force them in engagement with the feeding means; fourth, to provide a detachable means for holding the clip-holding means in position and which normally keeps in secure engagement with an abutment but which is quickly released when uncovered by a rearward movement or partial withdrawal of the blade-feeding slide; fifth, to provide a construction that is possible of economical construction as it is easily assembled, all the parts in themselves extremely simple. The rectangular form of the various parts, nesting one within the other, provide for the necessary accuracy and precision when feeding the blades into shaving position.
The invention is illustrated in the accompanying drawings in which Figure 1 is a front view of my improved razor with the shaving head folded, in which position it can receive a blade from the handle. Figure 2 is a similar view but mainly in central section showing the shaving head swung to shaving position. Figure 3 is a similar view showing the first step in releasing the clip-holding means. Figure 4 shows the clip-holding means released, and partly withdrawn and Figure 5 shows the said means ready for complete withdrawal, the feeding slide being returned to its innermost position. Figure 6 is a section on line 6—6 in Figure 2, the upper part being shown in elevation and Figure 7 is a similar view taken on line 7—7 in Figure 2. Figure 8 is an elevation of the right-hand side of Figure 1 and Figure 9 is a view of the rear of Figure 1. Figure 10 is a perspective view of the parts that are inside of the handle, these being shown slightly separated. Figure 11 is a section on line 11—11 in Figure 2 and Figure 12 is a perspective view of a clip of blades with the stack broken away to show the inside construction of the clip.
The razor comprises a handle 10 and a shaving head 11, the shaving head 11 being mounted on a post 12, being pivoted thereto as at 13 and slotted as at 14 so that it can receive the post when swung down to receive a blade so as to bring the various parts with their outside surfaces in substantial alignment to form a symmetrical and compact article when so folded. The handle 10 is usually made of square tubing into which the base 15 of the post 12 is forced and is slightly cut away on one edge to form the slot 16 through which a blade can pass. The shaving head receives a blade longitudinally, that is, the blade slides from the handle to one end of the shaving head 11 which clamps the blade when it is in place by means of a spring 17, the blade resting on the platform 18, the blade being shown at 19 with its cutting edge slightly in rear of the guard or fender 20.
These parts in the shaving head, with the exception of the spring 17, are of one piece, the fender 20 being in the form of a bar spaced from the platform 18 to provide a passage for lather and is open at the ends, being supported by the central rib 22 shown in dotted outline in Figure 1 and the bottom being shown in Figures 6 and 7, this rib being formed with inclined sides to facilitate washing it out by simply holding it in a stream of water, the material passing out freely on account of the open ends of this lather passage.
Inside the square tube is arranged the stack of blades and means for holding it and also means for propelling a blade at a time from the stack. Inside of the handle I place a guide which is formed of sheet metal, this guide being shown at 23 having the sides 24, and flanges 25 on which the clip 26 rests the bottom 27 of the guide having a spring lip 28 at its inner end which bears against the wall of the tube or handle and exerts a slight pressure toward the other wall, the function of which will be more apparent hereinafter. This guide 23 is held in place by a screw 29 or other suitable means. The slide 30 is rectangular, having two side walls and a top 31, the front end 32 of which is used to push the blades one at a time from the stack, this end 32 also acting to close the slit 16 in the handle when the slide is pushed all the way in. This keeps this end of the handle water-proof. The guide 23 and the slide 30 are assembled before they are inserted in the handle but when the guide 23 is fastened in position the slide is prevented from being pulled all the way out, the limiting being accomplished by indentations or ears 33 in the side walls of the slide case fitting in the slots 34 of the side walls of the guide 23. A suitable grip 35 at the end of the slide remains on the outside of the handle and is used for manipulating the slide and is usually slightly roughened so that it can be easily operated even if the hands are wet.
The clip 26 holds a stack of blades 26a, the blades passing out of the top to be fed forward by the slide and being pushed up from the bottom by a spring 43 which bears on the bottom 27 of the guide and engages the bottom of the stack in the clip as the clip is open at the bottom.
To manipulate the spring it is secured to a grip or handle consisting of a block 36 with a grip 37 on the end of it, the grip 37 fitting on the inside of the opening 38 in the end of the slide. This forms a tight and symmetrical closure when the parts are assembled. The spring has an extension 39 which acts as a means for detachably holding the spring in position so that the block 36 forms a holding means for the clip as it abuts thereon and holds it in position as shown in Figure 2 and Figure 7.
In the form shown the spring is provided with a hole 40 which snaps over a lug 41 bent up from the back edge of the guide 23, the end 39 being slightly bowed outward so that a click indicates that the parts are properly seated. The end 39 of the spring 43 is usually roughened as at 42 to provide an easy finger grip which is engaged by the finger nail when the parts are to be separated. Assuming that a clip is to be removed from the razor after its supply of blades is exhausted, it is only necessary to pull the slide out part way as shown in Figure 3. This uncovers the end of the extension 39 of the spring and it is pushed in and pulled back at the same time as shown in Figure 4. Then the slide 31 is pushed back into the handle again as shown in Figure 5 and then the spring 43 is pulled all the way out of the handle and it brings with it the clip 26. A new clip is then inserted through the opening in the end of the slide, passing in on the flanges 25 of the guide 23 and underneath the top plate 31 of the slide 30, the parts being held in a gentle spring contact by reason of the pressure of the spring lip 28 hereinbefore mentioned. The spring 43 is now replaced into the guide 23 by passing it through the open end of the slide and the end 39 of the spring snaps over the projection 41. It will be evident that when so held the slide 30 can be operated by pulling it back all the way and then pushing it in all the way which causes a new blade to be fed from the stack into the shaving head, this blade, of course, ejecting the one that is in the shaving head. The grip 35 conceals the catch or holding means indicated by the spring 39 and its roughened end 42 when the slide is in its normal or inner position.
There are no parts to be unscrewed for opening the end of the handle to receive the clip, therefore, saving time and furthermore the parts fit accurately and they are easily assembled and easily fitted into the inside of a square tube and a square handle, in turn, forms an article that does not turn in the hand when it is being used.
It will be evident that various modifications can be made in construction of the parts without departing from the scope of the invention.
