ELECTRIC SHAVER WITH SELECTIVE DEPRESSION OF THE VERTICALLY ADJUSTABLE SHEAR PLATE Filed March 8 1965 2 Sheets-Sheet 2 HENRICUS J.DR|ESSEN AGENT United States Patent 3,233,323 ELECTRIC SHAVER WITH fiELECTIVE DEPRES- SION OF THE VERTICALLY ADJUSTABLE SHEAR PLATE Henricus Josef Driessen, Drachten, Netherlands, assignor to North American Philips Company, Inc., New York, N.Y., a corporation of Delaware Filed Mar. 8, 1963, Ser. No. 263,979 Claims priority, application6 Netherlands, Mar. 20, 1962,
,177 4 Claims. (Cl. 30-432) This invention relates to a dry-shaving apparatus, the shear plate of which, in particular a shear cap, can be depressed against spring action until in a stop position, in which the plate, in a position parallel to a supporting surface of the apparatus on the skin, still partially projects above that supporting surface or lies substantially level therewith.
In such known devices the pressure of the shear cap on the kin is at first determined by the pressure of the spring which forces the shear cap outwards. After reaching the stop, the user may, if desired, increase the said pressure in accordance with the force with which he pushes the shaving apparatus against the skin. However, this appears to be insufficient to meet the needs of the individual users and thereby to avoid entirely for every type of user the danger of pinching of the skin.
As a matter of fact, the shear action is influenced by the difference in height between the shear cap :and the stretching edge, that is to say the above-mentioned supporting surface. If in the stop position the stretching edge is low with respect to the shear cap, the run-in, i.e. the possibility of the hair to enter the cutting area through the slots in the side wall of the shear cap, is large because the skin is stretched on the shear cap. However, with some users this results in irritation.
If the stretching edge is located substantially \as high as the shear cap, the run-in is small because the stretching edge holds the skin flat. With some razor users this prevents the possibility of readily shaving out.
Both individually and for various parts of the skin, the most favourable height is different.
The object of the invention is to provide a device which can better be adapted to the various conditions and uses, which device is characterized in that the stop member is adjustably provided for various depths of depression of the shear plate.
As a result of this it is achieved that the users are capable of adjusting, according to their individual needs, the distance through which the shear cap can be depressed against increasing spring pressure and determining themselves the position of the height of the cap with respect to the stretching edge in the position of the firmly engaging cap.
It should be noted that the function of the present device is to provide a vertically adjustable shear plate in which the shear plate may be selectively adjusted within a certain predetermined range of stops and full pressure may be applied. upon the shear plate in the stop position without additionally loading the shaver motor.
A favourable embodiment of the invention is that the stop member is adjustably provided in its height below a supporting edge of the shear plate. As a result of this, as stated above, the advantage is achieved that the user is capable of exerting pressure on the shear plate also in the stop position without additionally loading the motor of the shaving apparatus.
In order that the invention may readily be carried. into effect, certain embodiments thereof will now be described more fully, by way of example, with reference to the accompanying drawings, in which ice in which for the sake of clarity the shear plates are not shown.
FIG. 5 is a perspective view of the embodiment shown in FIG. 4.
FIGS. 6a and 6b are perspective views of the inner circumference of the shaving head mounts separated from the housing structure shown in FIG. 5.
FIG. 6c is a perspective view of the finger-operated lever 27.
FIG. 6d is a perspective view of the shear plate inner frame.
FIG. 7 is a bottom plan View of the shaver head frame member of this embodiment in which the parts shown in FIG. 6 are omitted.
FIG. 8 is a top plan view of a shear cap which is used in the second embodiment.
FIG. 9 shows a cross-section of a third embodiment.
FIG. 10 shows a cross-section of a fourth embodiment.
In FIG. 1, the housing 1 comprise a shaving head 2 which can be removed in known manner to expose openings 1A and 1B therein and comprises itself two shear plates 3 closing said openings 1A and 1B.
These shear plates 3 can be depressed against spring action because they rest in a manner corresponding to that shown in FIG. 9 on the driven blades 42 which are under spring action by means of springs 30. For the sake of clarity these blades are not shown in FIGS. 1 and 2. Below the shear plate 3 which is provided with asupporting edge or rim 4 there is located a stop ring 5 as clearly and individually seen in FIG. 3. This ring is provided with a series of upright teeth 6, the tips of which form the stop surface for the supporting edge 4 of the shear cap 3. In FIG. 1 the plate is shown in the stop position. It should be apparent that the stop ring 5 is a means for adjusting the shear plate of a dry shaver to various heights relative to the housing 1. This is accomplished by rotating a lever 11, hereinafter described.
The space between the teeth prevents the accumulation of parts of hair or dirt on the stop edge which might easily occur if a flat stop ring were used.
In order to obtain the adjustability of the height of the stop ring 5, the lower side of said ring is provided with 'a number of slightly inclined parts 7 which cooperatef with corresponding inclined surfiaces 8 on the part of the housing on which the ring 5 rests. In the lowest position with respect to the housing 1. The stop surface consequentiy can be adjusted continually between a lowest position and a position which is higher by twice the height of the inclined parts 7.
The two stop rings are coupled together because one of them is provided with a fork 9 and the other with a pin 10 located between the limbs of the fork 9. One of the stop rings i connected to a lever 11 which can be operated from outside the housing.
The second embodiment is shown in FIGS. 4 to 8. In this embodiment a shaving head 12 is provided in nor-. mal manner at the top side with apertures which are bounded by stretching edges 13 and edges of engagement 14 for the shear plates 15 which are provided with a number of radially projecting supporting abutments 16. A
A number of step-shaped recesses 19 are provided in the cylinder wall 17. Each step-shaped recess 19 forms a number of steps 20 and each step forms a surface of engagement for the abutments 16 of the shear plate 15. The abutments 16 are located. in the shaving head 12 in grooves 21 which are provided in the inner edge of the stretching edges and extend from the edge of engagement 14 downwards so that, when the cylinder 17 is rotated, the shear cap is not rotated but is-only capable of performing an up and down movement the depth of which is restricted by the surfaces of the various steps 20. Grooves 22 are provided on the inside of the cylinder wall1l7 and the thickened lower edge 18 joining the stepshaped recesses 19, the mutual distance of said grooves corresponding to that of the abutments 16, so that the shear plate can be removed downwards and cleaned. The stop cylinder 17 is journalled in the shaving head 12 by the edge 18 and enclosed by a shear plate 23. This plate is also provided with grooves 24 corresponding to the grooves21 and 22.
The stop cylinders are coupled together by a fork 25 on the one cylinder and an abutment 26 on the other, the cylinders being rotated by mesansof a lever 27 projecting outside the shaving head. This is clearly seen in FIGS. 4, 6a, 6b and 60.
In the third embodiment (FIG. 9) in a manner corresponding to that of FIG. 1 a shaving head 2 comprising shear plates 3 with supporting edges 4 is provided on the housing 1. The stop surfaces for the supporting edges 4 are constituted by the tips of two series of upright teeth 6.
These series are provided on a common base plate 28 which with an edge bent downwards rests on a number of strip-shaped wedges 30 which can be moved back and forth by means of an arm 31. As a result of this, the stop surfaces become located in a higher or lower position with respect to the housing and the depth of depression of the shear plates 3 is adjusted. Instead of separate wedges, for example also strips having a step-shaped or inclined cross-section provided in the longitudinal direction below the edge 29 may be used which can be inserted more or less inwards, for example by means of a tape-shaped member provided around the housing 1.
In FIG. 9 the position is shown in which the shear plates 3 engage the shaving head as a result of the spring action which is exerted on the driven blades 32.
In a fourth embodiment (FIG. 10) a driven blade 34 is in normal manner provided below the shear plate 33 which blade is coupled to a driving shaft 35 which consists of two parts, the driving shaft 13-5 and the elongated shaft 235, the driving shaft 135 being depressible in known manner through a certain distance against spring action in the form of spring 41 with respect to the elongated shaft 235. This driving shaft 35 together with the toothed wheel 36 are adjustable in height because the elongated shaft 235 rests on a step 37 of a step-shaped wedge 38, which may be moved back and forth by means of an arm 39. As a result of this, the depth of depression of the shear plate 33 is adjustable in its height. For a similar shaving apparatu having two separate cutting members, the arm 39 may be coupled to a wedge 38 below each of the cutting members. In this device the tilt- Q. ability of the shear plate 33 is obtained in known manner by means of the multiple-bent shaft 40 which is also maintained in the stop position.
