MAG SAFETY RAZOR Application fled April 2, 1927. Serial No. 180,878.

I This invention relates to improvements in safety razors.

Prior safety razors have been of the construction to ermit the replacement of a used or unfit hide to be removed from the blade holding ortion of the razor. In carrying out suc operation, it has been necessary in the majority of prior safety razors to perform the same by manual handling of the replaced and replacing blades, whereas in certain other forms of prior razors, while the construction affords a mechanical means for substituting the replacing blade forthe replaced blade, the replaced blade is deliv- 1 5 ered in such manner that it can be caught only by permitting the blade to fall under gravity into a waste basket, or the like, and requires either manual handling to remove the same from danger to others, or if deposited in a special cabinet or the like for waste razor blades, as is the custom on Pullman sleepers the, razor blades are accumulated in haphazard manner and require special handling.

Pursuant ,to my invention, my razor embodies structural features whereby the blade to be replaced is substituted by the replacing hlade'wholly automatically and without requiring manual handling of either blade, and the replaced blade is automatically assembled ina clip or the like for positioning in an orderly manner, and preferably to locate the sharp edges of the blades out of contact with any portion of the hand when the clip or the hke containing the accumulated replaced blades is removed from operative relation with the remaining portion of the razor.

My invention is particularly ada ted to a form of razor comprising a mec anismfor replacing the blades by a so-called repeating operation, similar to the repeat-. mg mechanism of rifles, machine guns and the like, which form of razor is usually of the collapsible type, and the repeating operation carried out while the razor parts are in their collapsed position.

In the most preferred forms of my invention, the operation of substituting the replacing blade for the replaced blade, automatically locates the replaced blade in a clip, to position the sharp edge of the bladev awa from the exposed faces of the clip so t at when the clip with the accumulated replaced blades, is handled manually or otherwise the sharp edges of the blades are removed so that all danger of cutting is entirely obviated.

Further features and objects of this invention will be more fully understood from the following detail description and the accompanying drawings, in which s I Fig.1 is a central vertical sectional view of a collapsible form of razor provided with my invention; this view illustrates therazor in its collapsed form, a charging clip being supplied with a certain number 0 razor blades and a discharging clip partially filled with replaced razor blades;

Fig. 7 is a perspective view showing the 35 razor parts in position for shaving; and

Fig. 8 is a perspective view of a container for the discarded blades and clip.

Referring to the drawings, the casing 10 of the body portion of the ,razor may be 03 lindrical in contour and have its lower end open, to freely receive the cap 12 to provide movement axially of the casing 10 for the purpose of substituting amew razor- I blade for the razor blade inuse by repeating or equivalent operation, 'astis described more fully hereinafter. The cap 12 may be milled at its lower, enlarged rim'portion to facilitate manual grippin of the same. a

As appears in Fig. 5, t e outer or cylin- 1 0 line 4-4- tion.

drical face of the casing 10 may be corrugated to impart stiffness to the material and to facilitate holding the same manually.

It will be observed that the holder portion 14 for holding the blade. 15 in use for shaving, is in collapsed position, when this form of razor is in its charging posi- For effecting such collapsed position, the holder 14 is usually mounted on a pivot 16 on the extension 17 of the casing 10 of the body of the razor, and the bevel 18 is provided for limiting the movement of the holder 14 to collapsed position.

The repeater mechanism for replacing a new blade for a used blade, may be of any desired arrangement. In the drawings, I have indicated one form of such repeater mechanism, associated with a clip 20 for stacking therein a number of new blades 21. Such form of clip 20 is usually formed of a strip of metal or like material which is bent to U-form to have three sides and one open side, the side opposite such open side being provided with an opening 22, of a width to freely receive therethrough the resilient tongue 23 of a holder for retaining the cli 20 within the barrel of the casing 10. ne end 24 of the clip 20 is fiat on its face and has an outwardly turned edge 25 extending in alignment with the edges of the open side, to serve as a guide face for guiding the slide 26 functioning in the repeater operation to move the lowermost new blade denoted 21a in Fig. 1 from the clip 20 into the holder 14 of the razor. The opposite end 27 of the clip 20 is preferably provided with a suitable positioning means, as in the form of a circular lug 28 adapted to be received and retained within a corresponding depression 29 in the extension 17 of the casing 10. Such guide face 25 and positioning lug 28 automatically 10- Y cate the open side of the clip 20 a predetermined distance above the inner face 30 of the casing 10, by reason of the engagement of the slide 26 with guide flange 25 and the lower edge of the end 27 as the slide 26 is moved to its inward position as illustrated in Fig. 1.

Such slide 26 .is secured at its outer end 31 to the inner face of the cap 12, to enable the slide 26 to be reciprocated in its repeater operation frorn inward position to outward position by 'manual reciprocation of the cap 12. Preferably, the slide 26 is of a U-cross sectional shape comprising a bottom portion 26a, see Fig. 2, and two opposite side or flange portions 266, one of which appears in Fig. 2. When the slide 26 is at its extreme inward position as is illustrated in Fig. 1, its forward or inner end 26 projects through the slot. 32 in the extension 17 of the casing 10, and its opposite sides or flange ortions 265 are disposed on opposite sides 0? the clip 20, and the for- 26, as well as to act when closed as a seal against the entry of dust or other foreign substances .within' the casing 10.

The aforesaid holder, comprising the resilient tongue 23, further includes a body portion 35, which may be in the form of a strip, and is provided with a lug 36 adapted to be received within the recess 37 on the inner face of the casing 10; to the body portion 35 is secured an inwardly turned strip portion 38, welded or otherwise suitably secured to the body portion 35, to locate its downwardly turned end 39, see Figs. 1 and 2, in engagement with the flat face of the end 24 of the clip 20, to thereby hold the clip 20 against displacement during the stage of reciprocating the plunger 26.

Such holder 35 further comprises the loop or thumb portion 38 to facilitate manual grasping of the same for the insertion and removal of the holder 35 within the casing 10. It will be observed that the loop or thumb portion 38 extends exteriorly of the charging opening 11 of the casing 10 when the positioning and retaining lug 36 of the holder 35 is located in its recess 37. As is shown in Fig. 1, the interior of the cap 12 is of sufiicient length to freely receive such loop or thumb portion 38 of the holder 35.

It will be further observed that when the holder 35 is being withdrawn from within the casing 10, the edge of its resilient tongue 23 is brought in contact with the inner face of the side 24 of the clip 20 and pushes the clip with any new blades contained therein, exteriorly of the casing 10.

The inner face 30 of the casing 10 is preferably squared to serve as a guide for the reciprocated slide 26 and its side or flanges 26a in its repeater movement.

The operation of the aforesaid parts of the razor will be largely understood from the hereinabove described construction. It will be noted that when the razor is in its shaving position, as indicated in Fig. 7, and it is desired to replace the used blade 15, the holder 14 is rotated about its pivot to locate the blade retaining opening of the holder 14 substantially in alignment with open side of the clip 2015 a positionon the guide face 25, whereupon the resilient tongue 23 of the holder 35 by pressure upon the stack of new blades 21 forces the lowermost new blade 21a, see Fig. 2, to a position slightly below the .open side of the clip 30 of the casing 10 in advance of the inward end 26 of the slide 26 and in alignment with the slot 32, whereby upon manually pushing the cap 12 and therewith the slide 26 inwardly of the casing 10, the forward end 26' of the slide 26 encounters the ,posterior edge of such lowermost new blade 21w, forces such new blade 21m from its position below the open end of the clip 20 through the slot 32 in the extension 17, thence into contact with the posterior edge 15a of the theretofore used blade 15, and upon further inward movementof the slide 26, such used blade 15 is moved fully through the blade retaining opening in the holder 14 and thence into the space 40 of the hollow upper casing 41.

Preferably, such upper casing 41 is provided with suitable means for receiving the replaced or theretofore used blades 15, as the same are successively replaced. As one such receiving means, and also to afford stacking of the used or replaced blades, I illustrate a holder 42, see Figs. 2 and 6, which may be in the form of a clip having a three side and one open side 43 construction similar to the aforesaid clip 20, see Fig. 6, but further provided with a self-contained spring finger 44, the free end of which extends through the slot 45' in one side of the clip 42, to engage and hold the replaced razor blades as the same are accumulated in the clip 42. The opposite end 46 of such spring finger 44 is referably integral with the body portion of the clip 42. Such clip 42, or other holding means, is preferably dis osed within the upper" casing 41 in coordinated relation with the path of ejection of each used blade, to successively receive such used blades 15 and stack the same one upon another, as is indicated at 47 in Fig. 6, and also preferably to position the sharp edges 48 of such blades 47 against an imperforate side of the clip 42, which may be disposed opposite to the open side 43 of the clip 42, also as is illustrated in Fig. 6.

It will be observed, as appears in Fig. 2 in full line outline, that each replaced or used blade 15 as it is pushed by the replacing blade 21a from the holder 14', the anterior portion 15b of such blade encounters the spring tongue 44 of the clip 42 and displaces the same against its tension, and

upon the full release of the displaced or used blade 15 from the holder 14, the

tension of the spring 44 moves the'samefrom its full line outlined position to its dot 20 to rest on the inner face or bottom to locate each such blade 15'into proper v stacked relation in the clip 42, and in align- Inzent with any previously stacked blades 4 Such clip 42 may be held resiliently in position by means of the spring50, which may be secured by the rivet 51 in predetermined position "within the upper casing 41. The interior of the upper casing 41 is preferably machined square to snugly receive the clip 42, and the edge 51-of the upper casing 41 is provided with suitable locking means to properly align and lock the upper casing 41 relative to the body casing 10, as by means of the pin 52 and bayonet slot 53, two of which may be employed at non-diametrical positions.

A fresh. charge of new razor blades in a clip 20 or equivalent is had by removing the holding means 35 to withdraw the wholly or partially depleted clip 20, and substitute therefor a clip having the fresh charge of razor blades.

The upper casing 41 is provided at its upper end with a cap 54, which may be screw the hands. The clip 42 containing the used or discarded blades may be-placed in a tube container 55, see Fig. 8, having a cap cover 56, such as is now usually employed for the carriage of a chargingclip containing new blades, or in any other suitable container for storage in a valise or otherwise, or for shipment to a razor-blade manufacturer or to a re-sharpener for re-sharpening, or other disposition of the same, under all of which circumstances the used blades are handledwithout danger of cutting.

It will also be noted that the user of my razor or my improved attachment to existing razors may readily ascertain the number of blades 21, contained in the charging clip 20, which is normally concealed in the handle casing 10, by removing the cap 52 of the upper casing 41, counting the number of discarded blades 47 in the discharge clip 42 and subtracting such number from the usual total of twenty, or other number of blades originally placed in the charging clip 20.

I prefer to supply the blades in a charging clip of the construction of the aforesaid clip 20, or equivalent, the razor edges of the clip of the construction of the aforesaid clip 42, or equivalent about the open side of the clip 20 as a guard clip, whereby upon charging such clip 20 and the contained .new blades in the handle casing 10, such It will also be clear that the upper casing 41 may be associated with the lower casing 10, to position the opening 51 of the upper casing 41 about the cap 12 or lower portion of the casing 10, to be employed as an extension of the handle of the razor when in shaving position.

My clip or equivalent collecting means for accumulating the discarded razor blades may be em loyed with other forms of razor constructions, and assembled to be associated with the blade holding portion of the razor to receive the discarded or replaced blades from the blade holding portion without requiring manual handling of the replacing and replaced blades.

Whereas I have'described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.
