INJECTOR AND BLADE DISPOSAL DEVICE FOR RAZORS Filed om. 1s, 1949 2 sheetsfsheet 1 Patented June 30, 1953 UNITED STATES PATENT OFFICE INJECTOR AND BLADE DISPOSAL DEVICE .FOR RAZORS Joseph C. Fennelly, Ross, Calif., assigner, b y mesne assignments, of one-half to H. Struve This invention relates Ato improvements in .an injector and blade removing device for 'injector type razors and refers more particularly to the hook or gripping attachment by which used blades are withdrawn from the razor into a disposal compartment of the injector housing.
This application is a continuation-impart of a previous application Serial No. 714,722, led Deceinber '7, 1946, now Patent No. 2,608,755.
An injector containing a magazine of new blades has heretofore been employed to change the blade or" a razor by aixing the injector to the head and reciprocating a slide in the injector simultaneously ejecting the old blade by introduction of a new unused blade, the disposal of the rejected blade requiring manual handling.
In my prior application there was disclosed an injector for this type of razor having a magazine compartment and a blade disposal compartment with a slide for introducing the new blade and a hook arrangement for extracting the used blades. The injector-extractor there disclosed was operably attached to the head of the razor in the conventional manner, that is, by inserting a wedge between the guard portion and top blade holding portion of the head.
The novelty in the instant invention lies principally in the design of the extractor hook, the use of springs on top of the magazine to assure positive operation of the extractor and the use of a lateral wedge to keep the blade in a proper position in the razor head so it may be engaged by the extractor attachment.
An object, therefore, of the invention is to provide an injector-extractor for razors Vhaving magazine and blade disposal compartments with a slide equipped with an extractor attachment anda depressing element on the extractor for automatically holding it in an inoperable position during the injection of the blade into the razor.
Another object is to provide an injectorextractor mechanism with magazine and blade disposal compartments and a magazine equipped with depressing springs which assure more Vpositive operation during the blade extraction.
A further object is to provide an injection and extraction device utilizing a wedge for attachment to the razor head, said wedge equipped with means for laterally moving the blade in the `razor head upon insertion of the wedge so the extraction member of the slide readily engages the blade.
Other `and further objects will appear from the description which follows.
In .the accompanying drawings which form a part of. the specication and are to be Vread in conjunction therewith and in which like reference numerals indicate like parts in the vvarious views,
Fig. 1 Vis a perspective side view of a blade injector-extractor mechanism embodying vthe invention,
Fig. 2 is an enlarged side sectional view of the injector-extractor shown attached to the head of the razor with a blade withdrawn from rthe razor and about to be deposited in the disposal compartment,
Fig. 3 is a sectional viewrta'ken along the line 3-3 in Fig. 2 in the direction of the arrows,
Fig. 4 is a view similar to Fig. 2 with the injector-extractor slide advanced from its vretracted position to move the bottom blade from the magazine compartment into the head of the razor.
Fig. 5 is a similar View to Fig. 4 with the slide advanced to its extreme forward position where the new blade is lodged in the head of the razor,
Fig. 6 is a View such as that shown in Fig. 5 with the extractor hook in engagement with an aperture in the blade at the beginning of the extraction operation,
Fig. 7 is a like view showing the manner of withdrawing the blade from the razor head by retraction of the slide and depicts the intermediate operation between Fig. 6 and Fig. 2,
Fig. 8 is a perspective detail of the blade holding magazine, and
Fig. 9 is a detail of the slide mechanism.
Referring to the drawings, and particularly Figs. 2 and 4 there is shown diagrammatically, a razor of the injector type, the head of the razor designated by the numeral I0 and the handle by the numeral I I. The injector-extractor shown attached `to the razor head in the various views consists of a housing I2 divided centrally into an upper magazine compartment I2a and a lower blad-e,l disposal compartment I2b. From the forward end of the housing and at one edge extends a wedge I3. IIfhis wedge is adapted to be inserted between the guard and blade holding portions of the razor head when the injector-extractor is put to use to inject or eject a blade. At the rear of the housing isremovably tted a closure I2c hinged on a pin I4 in the lower portion and secured by means of a pin I 4a in the upper portion. This provision for opening the rear of the blade may be eliminated, if desired.
The sides of the housing are slotted as shown at l5 and in these slots is reciprocated a slide I6 shown disassembled from the housing in Fig. 9. Attached to the sides of the slide on the outside f the housing are knobs, handles or wings such as the triangular shaped members I6a shown best in Figs. 1 and 9 for moving the slide back and forth. The base or floor portion of the slide has a raised portion in the form of an inverted trough |61), the forward end abutting the rear end of the lower blade of the magazine during the injection operation. Pivoted as by a rivet Il to the under side of the slide in the inverted trough I6b is a exible extractor I8. Beneath and at the free end of the extractor is a hook Ia and on top of the extractor and above the hook are cams or depressing elements 18h.
The magazine for the blades, probably best shown in Fig. 8, is a container I9 whose front end wall I9a has a lower slot-like opening near its bottom to permit transfer of blades from the magazine to the razor and a top |92) having a front extension I9c and a doubled back tongue or tail plate extension I9d. The blade magazine I8 is limited in its downward movement at the forward end by abutment of extension |90 with the stop or shoulder member 20 afxed to the inside forward wall of the upper compartment I2a of the housing.
Tongue ISd i'lts in a slot in the end closure I2C of the housing and serves as a pivot for the magazine as it moves during the injection and extraction of the blades as shown in Figs. 5, 6 and '7. Above the magazine and between its top and the top of the housing is placed a strip spring 2| which imposes constant downward pressure on the magazine and keeps it properly located within the housing for the discharge of new blades from the magazine to the razor and withdrawal of used blades from the razor to the disposal compartment I2b. Within the magazine are shown the new unused blades 23 held under spring pressure against the bottom by a strip spring 22. These blades have a small perforation or slot 23a near the rear ends and sharpened edges. The perforations or apertures are positioned to be engaged by the hook portion I8a prior to removal of the blade from the razor as hereinafter described. Y
Formed in the top edge of the wedge or key I3 by which the injector-extractor housing is attached to the razor is a tongue or cam plate, I3a. This tongue contacts the rear edge of the blade in the head and moves the blade forwardly to assure engagement of hook I8a with aperture 23a in the blade.
In operation a stack of new and unused blades are supplied to the magazine and the magazine inserted in the upper compartment of housing I2. The rear closure I2c is applied to the housing and slide IB retracted to a position shown in Fig. 2. The wedge I3 is then inserted into the head I0 of the razor and the slide is advanced until the inverted trough portion IGZ) abuts the rear end of the lower blade in the magazine. At this time the camming surface or depressing elements I8b on top of the extractor contact the lower surface of the blade and keep the hook Ia depressed in an inoperable position as shown in Fig. 4. Continued advancement of the slide as indicated in Fig. 4 feeds the blade from the magazine into the head of the razor until the slide reaches the position shown in Fig. 5 where the extractor hook is still depressed beneath the new blade. The housing is then removed from the razor and the razor is ready for use.
When it is desired to remove a used blade from the razor, wedge I3 is again inserted into the razor head and with the slide in its forward position, as shown in Fig. 6, the extractor hook will assume a raised position since cams I8b are outside of the housing and free of the depressing influence of the blades in the magazine. Hook ISa will now ride over the top of the blade in the razor head and engage aperture 23a in the manner shown in Fig. 6. The sequence of the extraction operations starting with Fig. 6 is continued in the showing in Fig. '7 at which time the blade is partially withdrawn from the razor. Note that as the slide is retracted cam members I8b conta-ct the bottom of the new blades lifting the front end of the magazine to permit easy access of the used blade into the disposal compartment. Continued retraction of the slide brings the used blade into a position shown in Fig. 2 when the slide is completely retracted and the used blade has been withdrawn completely into the disposal compartment of the housing. Forward movement of the slide from the position shown in Fig. 2 will disengage the used blade from the extractor hook and deposit the blade in the disposal compartment as shown in Fig. 4. This sequence of operations may be performed in injecting and extracting blades from the razor until the magazine of new blades has been exhausted. When the new blade magazine has been exhausted and the used blades deposited in the disposal compartment the housing may be replaced with a new injector-extractor containing a magazine of new blades.
Thus, it will be seen that there has been devised an improved type of injector-extractor magazine by which there may be positively injected a new blade into the head of a razor and an old blade withdrawn into a disposal compartment without manual handling of the individual blades during extraction of the blade from the razor head or subsequent disposal of the used blade. The design of the extractor hook, the depressing cams which hold the hook in an inoperable position while the blade is inserted in the razor and the spring mechanism above the magazine for imposing a constant downward pressure thereupon serve to effect more positive operation of the extractor. The lateral cam or wedge mechanism I3a which moves the blade forwardly in the head, likewise operates to assure engagement of the extractor hook with the blade aperture.
From the foregoing it will be seen that the invention is well adapted to attain the ends and objects hereinbefore set forth together with such other advantages which are obvious and which are inherent to the structure. As many possible embodiments may be made of the invention without departing from the scope thereof it is understood that all matter herein set forth or shown in the drawings is to be interpreted as illustrative and not in a limiting sense.
