6 Claims.

This invention relates to shaving clippers and its principal object is to provide a shaving clipper having manually operable means for imparting rapid reciprocating movement to a shaving cutter.

Another important object of the invention is to provide a shaving clipper having manually operable means for storing energy and means for transmitting the energy so stored to a reciprocating cutter.

Another object of the invention is the provision of a shaving clipper having means for converting force intermittently applied to a bandle into force continuously acting upon mechanism to impart relatively rapid reciprocating movement to a cutter.

And still another object is to provide an efiective manually operable shaving clipper of such form and compactness that it may be carried in a vest pocket or small purse or toilet kit.

Other objects and advantages will'be apparent from the following description, in which reference is had to the accompanying drawings illustrating a preferred embodiment of my invention and wherein similar reference numerals designate similar parts throughout the several views.

In the drawings:

Figure VI is a plan view similar to Figure IV but showing another modification of the operating mechanism;

Figure VII is an elevational view, partly in section, of the mechanism illustrated in Figure VI;

Figures VIII and IX are views similar respectively to Figures VI and VII but showing a further modification of the operating mechanism;

Figure X is an enlarged fragmentary sectional bottom plan view taken along the line X-X of Figure IX;

Figure X1 is a plan view, with parts of the upper casing member broken away and with the shaving head and cutter shown in section, illustrating still another formof the operating mechanism of my invention; and

Figure XII is an elevational view of the form of mechanism illustrated in Figure XI, the easin, shaving head, cutter and one of the gear elements being shown in section.

Referring to the drawings in detail and particularly to Figures 1, II and III thereof, the operating mechanism of my device is mounted within a casing consisting of a lower member I and a similar upper member 2. The casing may be made of stamped or die-cast metal or of a suitable molded plastic, and is small and flat so that it may be conveniently used and carried.

Rigidly interlocked'to the forward end of the casing members is a shaving head 3 which may be of any preferred form but which I have illustrated as terminating in a pair of

slotted plates

4 and 5 whose outer surfaces lies in planes that intersect at an angle, the edges of the slotted plates being slightly separated. Either the plate 4 or the plate 5 may be laid against and moved over the skin to be shaved; hence, the shaving clipper can be used either side out and manipulated by either the right or the left hand of the user. The apex of the angle at the intersection of the slotted plates lies at the end of the shaving clipper and may be moved up to and under the bows of spectacles, thus enabling persons who prefer to wear glasses while shaving to shave the areas adjacent the bows without displacing them. The arrangement of the plates with the apex of their intersection at the end of the shaving clipper also facilitates shaving adjacent the nose and ears.

The space encompassed by the shaving head with its terminal plates is tubular and diamond shaped in cross section, and mounted for sliding movement therein is a tubular cutter 6 the exterior shape of which conforms to the shape of the space within the head 3. The integral forward blades l and 8 of the cutter are slotted to cooperate with the

slotted plates

4 and 5, the edges of the teeth formed by the slots in the blades and plates acting in the well known manner, when the blades are reciprocated, to clip hairs which extend into the slots.

Rockably mounted on the trunnions I and "I having bearings in the casing members I and 2 is a lever II the forward end of which is received in a socket 12 formed in the rear side of the cutter 6, there being a light spring I! interposed between the end of the lever H and the cutter 6 to hold the slotted blades I and 8 with uniform pressure against the

slotted plates

4 and 5.

The rear end of the lever II is forked and receives an eccentric H which is fixed upon a shaft l5 journaled in bearings in the casing members l and 2. Also fixed upon the shaft [5 are a flywheel I6 and a pinion II, the pinion teeth 1 meshing with the teeth of a gear wheel III that is rotatably mounted upon a stud shaft is flxed to the casing member I.

Integral with the hub of the gear wheel I! is a pinion the teeth of which mesh with the teeth of an internal oval rack 2|. An oblong boss 22 depending from a plate 23 fixed to the rack engages the inner end of the stud shaft l9 and serves to keep the pinion 2|! and rack 2| in proper relationship. Extending from the rack 2| outwardly through a slot formed between the casing members I and 2 is a link 24 the outer end of which is pivoted to'ahandle 25. The handle 25 is fulcrumed on one of the screws 26 which secure the casing members together, and is yieldably forced outwardly by a spring 21 but may be manually pressed inwardly into the slot between the casing members. When the handle has been pressed into the slot it may be held therein by a hook 28 which may be engaged with and disengaged from the handle by means of a knurled sector 29 accessible at the end of the casing. When the handle is retained by the hook, the shaving clipper has the appearance illustrated in Figure I.

When the shaving clipper is to be used the handle is unhooked by turning the sector 29 and the spring 21 swings the handle outwardly. With either of the

shaving plates

4 or 5 laid against the skin to be shaved, the user presses the handle 25 inwardly, thus imparting rotative movement to the pinion 20 and the gear l8 which acts through the pinion II to spin the flywheel l6. As the handle 25 reaches the limit of its inward swing the end of the oval rack 2| rides around the pinion, and when the spring 21 swings the handle outwardly, rotative movement, in the same direction, continues to be imparted to the pinion 20, the gear I! and the flywheel IS. The energy stored in the flywheel acts through the gearing to cause the handle to swing out and in with a smooth. rhythmic motion.

By repeatedly pressing the handle at each inward swing, thus imparting movement directly to the pinion 20 and at the same time flexing the spring 21 so that it will react during the outward swing to continue imparting movement to the I pinion in the same direction, the user keeps the flywheel and the eccentric ll turning continuously at high speed. The eccentric rocks the lever II and thus reciprocates the shaving cutter 6. The high frequency reciprocation of the shaving cutter which results from the relatively low frequency swinging movement of the handle is sustained and steadied by the inertia of the flywheel, and the cutter 6 thus is caused to operate smoothly and eflectively.

The form of my device illustrated in Figures IV and V differs from that above described in that a link and crank mechanism is substitu ed for the oval internal rack and pinion mechanism of Figures II and III and that two handles instead of one are connected to the gearing. The casing members la and 2a, the shaving head Ia,

, the shaving cutter 6a, the lever Ila, the eccentric Ila and the pinion "a are similar to the corresponding parts of the form of my device already described with reference to Figures 1, II and III. The gear wheel lea is made heavy so that it may serve also as a flywheel, and is provided with a pair of cranks 230 which are connected by means of links 2411 to handles 25a, the handles being yieldably forced outwardly by springs 21d. For carrying compactness, the handles may be pressed into slots between the casing members and held in place by the hook 28a. Since the handles are so connected that they move outwardly and inwardly together, the hook 28a need be engaged with only one handle.

In operation the form of shaving clipper shown in Figures IV and V functions in a manner similar to the form shown in Figures I, II and III, except that the user presses the two handles inwardly instead of pressing only one.

When the operator presses the handles 25a he not only turns the gear wheel lBa, but, at the same time, he flexes the springs 210. so that they will react when the momentum of the gear wheel l8a has carried the links 24a beyond center," to force the handles outwardly, thus continuing to urge the gear wheel l8a to turn in the same direction.

The modification depicted in Figures VI and VII differs from that of Figures IV and V in that the pinion shaft I 512 carries a flywheel I 6b and in that the gear wheel I8!) is turned by one link 24b and one handle 25b. Since the shaving clipper can be used with either side out, the forms with only one handle may be reversed for convenient operation either in the right hand or the left hand of the user.

The mechanism illustrated in Figs. VI and VII functions to urge the gear wheel I 8b and the flywheel 16b to turn, without change of direction, during both the inward and the outward swing of the handle 25b. During the inward swing the force exerted upon the handle by the operator's hand pushes upon the link 24b to turn the gear wheel I81), and during the outward swing the spring at the handle pivot reacts to cause the handle to pull upon the link 24b and thus continue the turning movement of the gear wheel lib.

In the form shown in Figures VIII, IX and X the gear wheel llc is integral with a drum 300, to the inside wall of which is attached the outer end of a spiral spring Ilc, the inner end of the spiral spring being attached to a rotatable shaft 320. Fixed upon the shaft 32c is a ratchet wheel 33c-which is engaged by a spring pressed pawl 340 that is pivoted upon the casing member lo and acts to prevent the ratchet wheel 33c and shaft 32c from being turned backwardly by the spiral spring. The ratchet wheel 330 is engaged also by a spring pressed pawl 35c pivoted on a flange "c which is fixed to a pinion 31c mounted for free rotation on a bushing surrounding the shaft 320. The teeth of the pinion 31c mesh with the teeth of a rack formed upon a link c which is pivoted at its outer end to a handle 250. The handle He is swingably mounted at its forward end upon one of the screws which hold the casing members together, and is yieldably urged outwardly by a spring 210. The teeth of the gear wheel I80 mesh with the teeth of a pinion llc upon the shaft of which a flywheel IE is fixed, the structure and function of the flywheel I 60 being similar to the structure and function of the flywheels in the previously described modifications.

When the user presses the handle 25c inwardly it acts through the link 24c, the rack, the pinion, pawl 35c and ratchet-wheel 33c to'tum the shaft 320 and wind up the spiral spring. When the pressure is relieved the spring 210 swings the handle outwardly but the pawl 34c prevents the spiral spring from unwinding from its inner end by turning the shaft 320. By alternately pressing and releasing the handle 250, the user keeps the spiral spring partially wound even while it is unwinding at its outer end in turning the gear i8c and pinion He. The spiral spring thus spins the flywheel and imparts a steady, rapid reciprocating movement to the shaving cutter as long as the spring remains partially wound.

In the form of my invention embodied in the shaving clipper illustrated in Figures XI and XII, the handle 25d constitutes a winding key which is fixed upon a shaft 326.. Also fixed to the shaft 32d is a ratchet wheel 33d engaged by a pawl 36d to prevent the shaft 3211 from being turned backwardly by the action of a spiral spring 3id, the inner end of which is attached to the shaft. The outer end of the spiral'spring 3ld is attached to the inner wall of a drum 36d which is fixed upon a gear wheel 18d.

The teeth of the gear wheel i8d mesh with the teeth of the pinion i'id fixed upon a shaft iEd to which is fixed also a flywheel Hid. The spinning movement of the shaft i511 resulting from the action of the spiral spring M11 is transmitted, through a short gear train to an eccentric Md and a rocking lever Nd, to the reciprocating shaving cutter.

In order to prevent the mechanism from operating before the shaving head has been applied to the skin, a brake 40d, carried by one arm of a bell crank lever did, is held in frictional engagement with the flywheel ltd by means of a retractile spring 62d. The other arm of the bell crank lever carries a button 63d which is located outside the casing and is supported by the bell crank lever through an arcuate slot in the casing member. The retractile spring is so anchored to the casing and connected to the bell crank lever that when the button is at one end of the slot the brake is held in contact with the flywheel and when the button is pushed quite to the other end of the arcuate slot the brake is held by the spring out of contact with the flywheel. In using this form of the shaving clipper of my invention, the button is slipped to the left end of the slot to set the brake and the key is turned to wind up the spiral spring. The shaving head then is applied to the skin to be shaved and the brake released. The spring of course is rewound whenever the mechanism runs down.

It will be apparent from the foregoing description that I have provided a simple and compact shaving clipper which may be carried in the user's vest pocket or in a small purse or toilet kit and which may be used during railway, highway or air travel, and under almost all circumstances, whether or not water, light or electric current is available.
