HAIR RETAINER FOR SHAVEBS Filed Jan. 9, 1942 Hm Zanam' deZ Patented Mar. 30, 1943 HAIR RETAINER FOR SHAVERS Harry Landsledel; Wilton, Conm, assignor to Remington Rand Ina, Buffalo, N. Y., a corporation of Delaware Application January 9, 1942, Serial No. 426,136

13 Claims. I (01. 30-415) This invention relates to hair retainers for attachment to electric dry shavers and the like.

Many of the electric dry shavers, hair clippers and the like now being used commercially employ cutter structures having one or more shaver heads provided with an outer stationary cutter head structure and an inner movable cutter cooperating therewith in the shaving or hair cutting operation. These constructions have the ends of the cutter members open so that hair removed by the cutters in operation is discharged into the center of the cutters and then outwardly through the open ends.

The present invention is designed to provide a hair retainer to engage opposite ends of the cutter head-structures of the conventional shavers now being used for the purpose of retaining the hair against discharge from the open ends of the shaver heads. The retainers are constructed for ready attachment and detachment from the shaver in order that cuttings may be readily removed after use of the shavers. The retainer is constructed in unit form independent of the shaver to be readily attachable and detachable therefrom and yet is constructed so that it is easily applied and readily retained in position on the shaver to catch and retain cuttings in the normal use of the shaver.

In providing for convenient attachment and removal of the hair retainer from a shaver, the retainer provided by the invention has a pair of end members resiliently connected together to form the retainer and has a lever arrangement provided for use in operating the retainer to readily disengage the positioning means of the retainer from its cooperative engagement with the shaver when the retainer is .to be removed. The connecting means for the end members is designed to be operative to normally retain the end members in engaged relation on opposite ends of the head construction of a shaver through its own inherent operative construction independent of direct connection with the shaver by normally drawing the end members toward each other in maintaining engagement of the end members on opposite ends of a shaver head.

The retainer is constructed for ready removal by manual operation of suitable lever means that will disengage the positioning means for the end members from cooperative engagement with a shaver head and through the formation and construction of the end members the lever operation may be augmented by the structure of the end members to obtain a slip action or snap action in the manual operation of the levers to project the retainer bodily away from the shaver.

In the drawing the invention is illustrated as applied to a multiple head shaver wherein:

' Figure 1 shows one end portion of a shaver with the invention applied thereto, the scale being substantially enlarged and portions being broken away and shown in cross section for convenience in illustration.

Figure 2 is an end elevation of the shaver with the hair retainer mounted thereon as shown in Figure 1. I 1 a Figure 3 is a plan view of the shaver as shown in Figs. 1 and 2 with one end portion broken away and shown in cross section substantially on the line 3-3 of Fig. 2.

Figure 4 is a view similar to Fig, 1 showing one end portion of a shaver head in cross section and the retainer of the invention applied thereto and in a position partly removed from engagement with the shaver head illustrating the operation of the retainer in the detaching and projecting operation obtained in removing the retainer from the shaver, the illustration in cross section being.

taken substantially along the line 4 4 of Fig. 3.

Figure 51s a side elevation of an end member of the hair retainer showing the inner shaver head engaging face thereof.

The present invention is illustrated for application to a multiple head type of shaver and particularly with reference to a structure employing two shaver heads. The shaver includes the handle I normally housing the power driving unit or other suitable means for actuating the hair clipping or shaving mechanism. At one end the handle carries clipping devices or shaver heads 2,. two being shown mounted in spaced relation and projecting in the same direction from the handle as clearly illustrated in Figs. 1 and 3. The handle is provided with spaced channels 3 for receiving the base portions of the shaver head in a manner used in connection with conventional shavers. The sides of the handle terminate at the end carrying shaver head 2 so as to be substantially flush or coincident with the ends of head 2.

The hair retainer provided by this invention .is constructed to show its structural features and operation when applied to a multiple head shaver using two heads. It is to be understood, however, that applicant's retainer may beconstructed with the features of construction hereinafter described so as to be applicable to either a single head shaver or a multiple head shaver having more than two heads.

The retainer comprises a pair of end members 4 that are of duplicate structure but reversed in position with respect to one another so that one sideof each end member is constructed to engage the end 01' a shaver head-or heads. this side of one end member facingthe corresponding side of the other. The end member has the shaver head engaging side or face constructed as illustrated rather clearly in Fig. 5 with a shaver head engaging section 6 for each shaver head. Two sections 6 are provided in the structure illustrated by the drawing, spaced apart the proper distance to flt the spacing of the two heads 2 illustrated in the drawing. The outer edges of sections 8 are formed to flt the outer contour of shaver heads 2 at the outer side edges and at the outer free ends of the shaver head provided with the shaving sections for engagement with the skin to be shaved. The sections 6 are joined by a central web I having a recess 8 adapted to receive the looped end 9 of a coil spring ID, A retaining pin H has a driving fit in a bore formed in web I in transversely extending relation to recess 8 and so positioned that pin II when driven into the bore in web I will extend through loop 9 of coil spring ID as shown in Figs. 1 and 3 for attaching the end of coil spring ID to end member 4. The opposite ends of coil spring H] are attached to the two end members used for engaging with opposite ends of the shaver-heads as illustrated, so that the twd end members are directly connected together for a limited pivotal movement relative to coil spring in connected relation. Coil spring ill is so constructed that in its untensioned position it will support end members a at a spaced distance apart that is less than the distance between the opposite ends ofthe shaver heads to which the end members are to be applied.

Each end member 4 has each shaver head engaging section 6 thereof provided with a flange or projecting portion !2 extending perpendicular to the inner face of section 6 for slidably interfitting in the end of a shaver head 2 in a manner illustrated in Fig. 3. This projection of flange l2 cooperates with the face of each section 8 to form a seat for receiving the open end of the stationary cutter of a shaver head. When this flange i2 is engaged in a shaver head in the manner illustrated in Fig. 3, the end member is seated in cooperative relation with theshaver head so that it cannot be disengaged therefrom by sidewise movement but only by movement in a direction perpendicular to the end of the shaver head in a manner that will be hereinafter described.

Flange i2 may be made in continuous form to engage the inside edge of the open end of a shaver head or it may be made in sections having portions spaced apart somewhat in the manner as illustrated in Fig. 5. It will be noted in Fig. that a substantial portion of the flange ii for each section 6 is continuous, particularly the top and inside portions thereof while at the outside edges, each section of this flange is discontinued at [3 and another section thereof provided in the form of projection M. It is to be under stood that this flange may be made to engage either the inner or outer faces of the shaver head, it beingunderstood that when the flanges are engaged with the inner faces of the stationary member it will not interfere with the operation of the movable cutter-member. Constructions may also be found-desirable for use with some type of shavers wherein sections of the flange may engage the outer edges of the sta,

tionary part of the shaver head construction and other portions may engage the inner edges, it

being obvious that such variations in arrangement may be made to suit different types and designs of shaver head structures and still provide the positioning means to retain the end members against lateral movement when engaged with the shaver heads.

It is also desirable in constructing hair retainers to have them readily attachable and detachable irom the shaver and shaver head construction thereof. For this purpose the present invention incorporates a projecting portion ii on each end member to provide alever operable when it is desired to remove the retainer from the shaver. This lever structure is arranged so that when the end members are retained in position on opposite ends of a shaver head by spring III as illustrated in Fig. 1, the lever will be spaced away from the adjacent end portions of the shaver. In cross section the levers ii are constructed as shown in Figs. 1 and 4 so as to be rather thick at the juncture between the lever end and the end member where the lever joins section 6. From this juncture the outer face of the end member is tapered toward the free end of the lever as indicated at l6 to provide a. cam surface while the lower end portion of each section 6 provides a fulcrum or pivot ii for the lever ii to secure the operation that will now be described.

With the hair retainer applied to a shaver in the manner illustrated in Fig. 1, the connecting means in the form of spring I is tensioned to draw end members 4 toward each other and retain them in clamped or engaged relation on opposite ends of shaver heads 2 with positioning means or flanges l2 cooperating to retain the end members against lateral sliding movement or disengagement from the shaver head.

In removing the retainer from a shaver, it may be obtained by manual operation by engaging the end of a finger in the manner illustrated in dot and dash lines of Fig. 4 with the inclined cam surface l6 of lever l5. If desired, the thumb and forefinger may be used to simultaneously engage the end of each finger with one of the inclined surfaces I6 of the end members at each end of the shaver head. By manually pressing the lever toward the shaver, either one or both levers of the end members, each end member will be caused to rock on fulcrum H with the end of the lever moving toward the shaver. As soon'as this rocking movement assumes a position where flange i2 is moved out beyond the free end of shaver head 2, the inclination of the cam surface IB is such that by having a smooth outer face on the end members. a slipping action may take place so that the end members will slip out from under the end of the fingers or finger being used, as the case may be. This slipping action will occur in pressing the fingers toward the shaver while the end members will slip sideways or along the face of the sides of the shaver and the ends of the shaver heads in a direction outa or 7 heads.

ated so that this projecting action is not necessarily obtainedbut the rocking oi the end members may be obtained as illustrated in Big. 4, and the retainer removed by laterally sliding the retainers on the shaver into a disengaged relation Q with flange or positioning means it, formed-to when the retainer is engaged on the shaver. It should also be understood that where the retainer is constructed for use-on only a single headed shaver that two springs ill or the like of any suitable shape, may be used in connected relation to the end members so as to lie on opposite sides of the shaver head when applied to a single headed shaver. On av multiple headed shaver, however, it is not necessary touse the resilient connecting means on the outer sides of the heads since a co-action is obtained between the sections provide a pocket or socket I! to, receive cuttings removed by the-shaver headsin their operation, I

In this connection it has been found with con-. ventional shavers oi the character illustrated in the drawing. that a reciprocating inner cutter will elect cuttings through the open ends thereof and outwardly beyond the open ends of the head As a result, pockets ill will receive these vcuttings and upon the removal of the end members from a shaver the cuttings may be conveniently removed from the retainer anddumped into a waste basket or disposed of in any suitable manner.

It will also be understood that the end members may be operated in removing them from the shaver by lifting up lever I5 so as to move it away from the shaver. This operation can be obtained by engaging a finger nail under the end of lever i5v and then lifting it up until the end of the ilnger may be engaged thereunder whereupon the lever may be grasped between the thumb and forefinger if desired and the entire end member removed from engagement with the shaver and shaver as shown in Fig. 1 and then by manually stretching spring i0 until the other end is engaged over the opposite side of the shaver when it may be released and slidably moved on the side of the shaver until positioning means I! is seated in interengaged relation with the shaver head.

It is conceivable that other ways of applying and detaching the retainer constructed as illustrated in the drawing and described above upon a shaver head may be obtained due to the fact that spring I0 is sufficiently flexible to permit almost any manual manipulation of the end members to space them apart in various relations to one another and at a distance greater than the length of the shaver head in engaging and disengaging the end members in position on a shaver. The above methods are explained to illustrate various ways of conveniently attaching and detaching the retainer of the present invention on' a shaver head.

It is to be understood that more than one resilient' means or spring l0 may be used to connect the end members. For example, where more than two .shaver heads are used, additional springs ID or other suitable connecting means that can be elongated and shortened as desired, may be used in the manner illustrated in'the drawing, so that the connecting means will lie in the space between two spaced shaver heads 1 to: engsginsennsnav rheso whereby both sections are effectively retainediin engagement with the shaver heads in the-manner iiiustrated in the drawing by the tension of the spring in the'applied position of theretainer on a shaver.

The exterior shape of the end members is illustrated as being rounded which will obviously ellminatesharp corners at those portions that may be engaged with the surface of the skin or likely to become engaged therewith during the use of theshaver. The shape of the end members may be varied from that shown in the drawv .ing'to any desired extent in order to conveniently lit and cooperate with shaver constructions of a hair retaining and catching unit wherein no special means is required to be operated to secure the attachment anddetac'hment of the unit to the shaver.

It is to be further understood that end members 4 may .be made of metal, plastic, wood or other suitable material now well-known in the artand that the connecting means Ill may be made from; coil spring wire of the character illustrated in the drawing or may be made in any suitable shape, size or form and of any suitable material to secure the operation of the end members in the manner described, the drawing illustration only one form of application of the invention.
