Renewed September 13, 1937 32 Claims.

This invention relates to certain improvements in shaving or hair clipping devices of the character generally shown in the patent tofichick, 421,757,978, granted May 13, 1930. Shaving devices of this general character employ an outer shaving head which is channel-shaped in cross section and transversely slotted and within said shaving head is disposed a cutter or shearing member which is reciprocated by an electric motor or other means so as to clip off or shear ofi hairs that protrude through the slots of the head.

Devices of this kind as placed upon the market are open to the objection that there are two relatively sharp corners on each side of the shaving head and two'relatively sharp corners at the extremities of the shaving head. These corners, when the instrument is pressed against the face or other part, are annoying and uncomiortable, particularly inasmuch as the device must be pressed firmly against the face in order that it shall cut properly and make a clean shave. In devices of this kind, the channelshaped head is held in place against accidental detachment by means of a set screw passing through a channel-shaped recess in the handle, which recess contains the head. Due to the very rapid vibrations given to the cutter within the head, this set screw often becomes loosened and in that case, the head is'liable to fall out, carrying with it the cutter, and the cutter and head may drop against somevery-hard object as, for instance, a washstand, floor or the like, and damage the cutter head or the cutter itself, thus rendering the instrument impossible for use until these parts have been replaced or duplicated at considerable expense.

-The general object of the present invention is to avoid the objections heretofore referred to by forming the lateral edges of the channelshaped head with rounded beads at the longitudinal corners of the head, which rounded beads at their outer portions merge into the transverse ly straight surface of the channeled head, thus presenting a curved surface for engagement with the cheek instead of the right angular corner which is present in this instrument asfound upon the market. 1

another object of this invention in this con-,- nection is to form these beads with slots that are enlarged towards their outerends so that the hairs may beguided into place, thus facilitating the cutting operation.

A further object is to provide guards mounted upon the handle of the device and which extend across both .ends of the channel-shaped head, v which will hold the channel-shaped head in position without the necessity and in this connection, to

of using a set screw, provide a clip which will engage these guards and hold them closed until the clip is removed.

A still further object is to perform this function by the provision of two guards hinged to the handle or body of the device, which guards may be turned up to a position against the open ends of the channel-shaped memberor head to thereby hold the channeled head and cutter from accidental detachment and when in position, these guardsand open accidently,

has a positive engagement with will not permit the guards to A still further object is to so form the ex-- ing drawing wherein- Figure l is a side elevation of a shaver to which my improvements are applicable, Figure 1 showing these improvements applied;

Figure 2 is a very greatly enlarged end view of the upper portion of the handle showing a guard closed and held in place by the clip;

Figure 3 is a side elevation of the cutter carrying end of the handle, showing the manner in which the guards are pivoted to this handle and how these guards engage with the channeled member to hold itin place;

Figure 4 is a top plan view of the structure shown in Figure l;

Figure 5 is an elevation of the cutter carrying end of the handle but with the guard turned outward, the pivoted head portion of the guard being shown in section;

Figure 6 is a greatly enlarged fragmentary vertical section through the end of the channeled member and of the cutter;

Figure 7 is a fragmentary side elevation of the ,structure shown in Figure 6;

Figure 8 is a section through one of the guards on the line 88 of Figure 3.

Referring to this drawing, l0 designates a handle which is formed at its cutter carrying end with a transverse open-ended channel ll. Disposed within the channel II isa head I2, which,

is held from movement by means which will be later described. That portion of the head which projects beyond the extremity of the handle has inwardly and upwardly inclined side faces l3 provide a clip which,

partly in section terminating in beads M which extend along the channeled head. The outer end of this head is formed with transversely extending slots It, as shown in Figure 7, these slots being very close together and defining a transversely extendinil series of knives, as they may be: called, it. The head 12 is formed with a longitudinally extending passage or channel ll within which is disposed a reciprocating cutter shown in Figure 5 and desig nated l8. This cutter fits this channel and at its upper end the cutter is formed with a plurality of transversely extending slots defining ,a plurality of transversely extending cutting knives l9, as shown in Figure 6. So far, I have described, except for the beads II, the ordinary and common construction of a shaver of this particular type. The cutter is is rapidly reciprocated longitudinally of the channeled head i2 by an electric motor contained within the handle ID. This forms no part of my invention, and as it is well known, I have not attempted to illustrate it. p

In shavers of this type, the channeled head i2 is normally held in place by a set screw passing through the upper end of the handle [0. As before stated, this set screw, due to the rapid vibrations of the cutter, is very likely to be Jarred loose and if loose permits the channeled head and the cutter to drop out of the handle. In order to avoid this, I have provided at each end of the channel II a guard, as shown in Figure 3. These guards are designated 20. 'Each guard at its lower end has an inwardly curved arm or equivalent element 2i, which extends into a recess 22 formed in the handle or body "I, and each guard is pivoted to the body by means of a transversely extending pivot pin 23. Thus each guard may be turned down into a position at right angles to the longitudinal axis of the handle or into the position shown in Figure 3, where the guards are juxtaposed to the open ends of the channel ii and the open ends of the .channel ll. Each of these guards at its outer end is rounded, as at 24, so that its outer face extends longitudinally of the guard and inward towards and merges into the flat upper face of the channeled head l2.

It will thus be seen that the lateral corners of the channeled head l2 are rounded by reason of the provision of the beads ll, while the ends of the channeled head are rounded off by means of the curved surfaces 24 of the guards and the four junctions of these curved surfaces are also rounded. Each end of the head i2 is provided with a lip 25, having a sloping upper surface, as shown in Figures 3 and 5, and just above the pivot 23, each of the guards 20 is formed with a recess 26 and a lug 21 which forms the outer wall of the recess and which overhangs the corresponding lip 25, so that when the guards are in the position shown in Figure 3, they not only prevent any longitudinal movement of the head l2 within the channel II, but they prevent any outward movement of the head i2 out of the channel ll. Thus the head l2 with the cutter is held firmly in place by the guards against any accidential detachment, as shown most clearly in Figure 3;

The guards 20 are held in the position shown in Figures 2 and, 3 by means of a clip 28, the

ends of which clip are angularly bent at 29 to extend across the outer face of each guard. The clip near its extremities has each of its arms formed with a depressed portion 30, as shownin Figure 8, the corresponding guard i2 having therein a recess 3i to receive this depressed portion of the clip so that when the clip is in place,

the ends of the'channel II.

it positively locks into the guards and prevents any accidental detachment of the clip. Preferably the handle adiacent its cutter carrying end will be provided with a transversely extending groove 12, as shown in Figure 2, into which the body of the clip is received so as to prevent the clip from being accidently pushed outward or upward in Figure 2. The extremity of the clip is outwardly bent, as at 33, so as to form means whereby the clip may be readily sprung outward to release it from its engagement with the guards and permit its withdrawal from the guards.- Preferably each guard is formed with a groove 34 which extends inward from one side edge of the guard to the recess 3|, as shown in Figure 8, so as to permit the clip to be readily pushed into place, or in other words, guide the portion 30 of the clip into position.

It will be seen that when the clip is in place,

' it isheld from any accidental detachment and that it holds the guards 20 in the position shown in Figure 3 and in turn these guards prevent any possible accidental detachment of the head l2 or the cutter which reciprocates within the head.

Another feature of my invention consists in forming the slots I5 in the beads ll-wider at their outer ends than at their inner ends, as shown in Figures 6 and 7, so that as the instrument is passed over the face, the hairs will be guided into position in these slots l5. It will be understood that Figure 7 is very much exaggerated and that the spaces between the slots are shown as relatively wide, whereas, as a matter of fact, the slots are very close together.

It will be seen with this construction that I have entirely eliminated the shapedged corners which in the ordinary shaver of this type form an obstructionto the free passage of the shaver over the face, particularly over those portions of the face wherein the flesh is depressed for any reason. The beads i4 extend, as before stated, longitudinally along the entire lateral faces of the head ii at the outer end thereof while the rounded ends of the guards 24 elimihate the right angular corners at the extremities of the head l2. Thus smooth rounded surfaces are presented at the side edges and and edges of the head i2, permitting the razor to glide easily and smoothly over the face. Furthermore, these guards 20 act to lock the head I! in its channel Ii and prevent any accidental detachment oi this head either by falling out of the channel longitudinallyof the handle or dropping out of i The clip 28 interlocks inthe recesses 30 with the guards so that this clip cannot be accidently withdrawn or fall off. The clip must be positively pushed out in order to free the guards; then the guards may be turned down to a position at right angles to the longitudinal axis of the handle and the head l2 with the cutter within it may be readily withdrawn. It will be seen that each guard, as shown in Figure 2, is provided with an opening 35, which is coincident with the ends of the channel I'I, so that by blowing through this It will be seen that I have secured the fol lowing advantages by my construction:

First, comfort for the person whose beard is being clipped or shaved;

Second, security against interruption of the mechanical functioning of the clipping machine;

Third, security against damage to fragile and expensive parts;

Fourth, ease in disassembling for cleaning and ease in reassembling the parts, and

Fifth, neatness in construction and appearance.

I am aware of the fact that certain shaving devices of this same general character have 15 transversely rounded shearing heads and transversely rounded cutters operating within the shearing heads. These transversely rounded shearing heads, of course, do not present sharp longitudinal. corners but, nevertheless, they have sharp end corners and, hence, the provision of the guards on suchshaving devices as last described, is desirable and does away with these sharp corners.

While I have described both guards 20 as being hinged or pivoted by means of the pivot-pins 23, I do not wish to be limited to this as it is obvious that one of these guards, or both of them, might be permanently fixed in closed position and rigidly attached to the handle. If one guard were permanently fixed, the head l2 might still be secured in its position in the handle by the means which I have already described. If both guards were permanently fixed, however, the lugs 27 and the lips 25 would be eliminated and separate means provided for holding the head 12 in position. However, I prefer to make both of these guards pivoted guards and to secure the head in place by the means which I have described.
