Themain object of the invention is to produce a device of this character which would be simple in construction, have only a few parts, easily replaced, and which would, for these reasons, be available to a larger number of users because of the low cost of manufacture. It is, at the same time, an object of the present invention to accomplish the aforesaid improvements in structure and reduction in cost of manufacture without in. any way detracting from the eilciency of the device. Among other objects may be mentioned a novel and simple way of securing the shear plate, i. e., the plate in which the stationary shearing teeth are located, to the cutting head lof the ailiance; greatly"`facilitated means of egress of e clipped hair from the cutting head, with the concomitant avoidance of all clogging therein; and a simplied, rugged driving mechanism. Other objects of the invention will become apparent from the specification which follows.
-In the drawing, Fig. l is a plan view of a characteristic embodiment of the invention, after removing one half of the housing for the mechanism. Fig.`2 is a. view of the same device looking at one end of the head, the lower portion of the structure being broken on'. Fig. 3 is an enlarged cross section of the head taken along the line 3 3 of`Fig. l. Fig. 4 isa similarly enlarged top view of the device, partly in section with the cutter removed. Fig. 5 is a cross section of the same device taken along the line afs-5 of Fig. 4.

Figs. 12-13 are details showing fractional top views of the shear plate,` with flaring ends of the slots, the slots in Fig. l2 being separated by a solid strip,
and going all the way across in Fig. 13. Fig. 14
isa cross section o a modied head. Fig.' 15 is a ldiagrammatical view of a modified driving mechanism. t l
Referring to the gures in detail, l is a housing and 2 a head removably attached to the housing i, as by means of a. screw 6. 'I'he head 2 comprises a block l which ts into a recess 3 of the housing l and is secured against longitudinal displacementby-a rib d lodged in a recess 5 of the block l. At each end of the block l are standards 8, on either side of a. longitudinal grove 9 55 4has longitudinal lips it extended at their ends into legs is which rest on the block l, in the groove t, between the standards t. The lower portions 2t of the legs l@ spread outwardly against the walls of the recesses it and, in the assembly, are forced in between the standards 8, edectively securing the legs l@ and the entire shear plate i5 in position. The slots ll oi the shear plate l5 extend into the lips it, but terminate short ci their outer edges. The slots ci the shear plate may be separated by a solid strip, as in Fig. 3, or may go all the way across, as in Fig. 6.
The driving mechanism is an oscillator of standard type for an A. C. supply. It consists of an electromagnet 2t secured tothe housing i. as by means of screws 25, and an armature bar 2, one end of which, tl, is pivoted in a socket 23 on a bracket 2S secured to the housing l 4by screws 36, and the other end, 23, is lodged in a hole in the cutter 2l. The oscillation of the armature bar 26 is edected by the intermittent attraction of the electrommet 2t and repulsion due to the action of a spring Si, the resiliency of which is such as to prevent the armature bar from making actual contact with the pole of the electromag net, thus avoiding the noise and vibration caused by repeated impacts. Means for adjusting the travel of the armature bar comprise a standard screw and slot arrangement 33 on a. bracket 32 ofthe housing i.
The block l is provided with a hole il for the passage of the amature bar Re. and two additional holes l2l for housing the resilient means i3 for urging the cutter t! onto the shear plate l5. The side walls it of the block l are tapered, the upper edges extending slightly beyond the lips it of the shear plate l 5, but leaving an open space between the lips I3 and the walls it. This arrangement aords the` clipped hair a readyv egress from the head 2, through the open space between the walls ld and lips-lt, and down the incline of the walls i5.
From the terminals 34, te, connected 'to a supply of alternating current, leads 3S, 31, complete l the electrical circuit. However, the lead 36, connected to the terminal 3.6,
presently explained.
has an intermediate 'y binding post se, the purpose of, which will be- When the current supply is from a direct current source, an interrupter is added to the mechanism. Buch an interrupter is diagrammatically illustrated in Fig. 15. It is mounted on a bracket 33 which is secured to thehousing I by means of the same screws 25 which secure the electromagnet 24 thereto. The bracket 33 has a ange 46 carryinga contact member 4I. A cooperating contact member 42 is carried by a nat spring 43, one end of which is secured to the bracket 36, as by a screw 44. The other end of the spring, denoted by the numeral 45, passes through an openlng 46 in the armature bar 26, under an acute angle therewith. 'I'he binding post 36 of Fig. 1
is indicated in Fig. 15 in dotted line. The lead 36 is now connected to the spring 43 at 44. In the ligure, the contact members 4|, 42, are shown in contact. The path of the current is from the terminal 34, over the lead 36, spring 43, and contact members 4I-42, to the electromagnet 24, and from the electromagnet 24 over the lead 31 back to the terminal 35. The larmature bar 26 is attracted by the electromagnet 24, whereupon, owing to the inclination of the end 45 of the spring 43, in the opening 46 of the armature bar 26, the contact member 42 will be raised out of contact with the contact member 4I thus breaking the circuit.
It will be observed that all one has to do to adapt the type of device shown in Fig. 1 to the one illustrated in'lig. 15, is to provide the armature y bar 26 with the opening 46, which may be done in all cases, whether the opening is to be used, or not. The interrupter can then be added to the mechanism whenever desired, without changing the standard mechanism. To change the type of device from one adapted for use with an A. C., to one adapted for use with a D. C., all one needs to do is to screw the bracket 3u, with its auxiliary parts, onto the plate carrying the electromagnet 24, using the same screws and screw holes, disconnect the lead 36 from the binding post 33, and A connect it to the spring 43 at 44.
When the shear plate I5 is of the form shown in Figs. 10, 11, the teeth of the cutter 2I will, of course, be bounded by a correspondingly curved surface.
It is usual to make the open ends of the slots I1 flaring, at the same time beveling or rounding the ends of the teeth of the shear plate I5, as illustrated in Figs. 12 and 13, to facilitate the entry of hair into the cutting mechanism.
The upper portions 5f the standards 3 are rounded and extend sufciently far from the ends of the shear plate I5 to protect the skin from possible injury by the corners of the shear plate.
When current isl supplied to the device in the manner above indicated, the end 23 of the armature bar 26 will cause the cutter 2l to have a reciprocating motion, as is well understood in iitting in between said standards, legs at the ends of said shear plate having outwardly naring portions, said standards being provided with recesses to receive said ilaring leg portions, longitudinal lips on said shear plate overhanging the side walls of said block and spaced therefrom to permit egress of the clipped hair, teeth formed by transverse slots in said shear plate extending into said lips .but terminating short of their outer edges, a cutter movable in said block under said shear plate having teeth in sliding contact with the teeth of said shear plate, and means for moving said cutter relatively to said shear plate.

It is believed that the structure of the device and its operation are so simple as to require no further explanation.
