Oct. 29, 1957 N. s. BRODY 2,810,953



Application October 3, 1955, Serial No. 538,178 3 Claims. (Cl. 30-30) My invention relates to an improved hair trimmer which is provided with a curved spring tension clip and an attachable curved handle. Said clip employs in its assembly a small, curved comb and, additionally, a double edge safety-razor blade, said latter being thin and resilient and having a central longitudinal perforation like most of the conventional double edge safety razor blades. One of the outstanding features of my invention is, that no springs are employed to provide the clamping tension to hold said safety-razor blades in their place whetrinserted into said clip; instead, the clamping tension is provided by the resiliency of said safety-razor blades themselves. A second outstanding feature of my invention is had in the curved condition of bottom sections of two clamping parts comprising said spring tension clip of my invention, and also in the curvature of said attachable handle, both of which correspond with the curvatures of the back of the head, nape and neck and thus make for better and more efficient application of the assembled clip hair trimmer of my invention. A third novel feature of my invention is had in the attachable handle which is, alternatively, attached to either side of. said assembled clip; thus said latter need not be readjusted when shifted from one side of the back of the head to the other side.

In the accompanying drawings Fig. 1 shows a face view of my invention fully assembled. Fig. 2 shows the reverse side of said tension clip by itself, presenting a perspective view of same. Fig. 3 shows the middle, bottom clamping section of the upper part of said clip on its inner side; here to, it can be seen how said safetyrazor blade is inserted and clampingly held by said straight side of said rigid tooth centrally positioned between said two severed sides of said longer clamping part of said clip. Fig. 4 shows a face view section of the stamped out sheet of metal of said upper clip part presenting an enlarged view of said rigid tooth prior to the forming of same into a vertical position. Fig. 5 shows said rigid tooth in the process of being formed. Fig. 6 shows a view of my invention as one would see it on looking down from above Fig. 1, thus showing the curvatures of said blade clamping parts and of said handle.

To present the details of my invention: in Fig. 1, 1 indicates the upper clamping part of said spring tension clip; 2 indicates the bottom clamping part of said clip; 3, 3 indicate the two groups of oppositely positioned arched bands, pierced and formed in the horizontal mid section of said upper part of said clip; said two groups of raised, arched bands are to receive, alternatively, said attachable handle at the one side or at the other side of said assembled clip hair trimmer for the operating of same; said two groups of bands begin with a larger semi circle and taper to a smaller arched band thus providing a snug grip on the tapering tongue of said handle; 4 indicates the holes in back of or underneath said raised, arched bands; 5, 5 indicate the two curved and severed 2,81%,953 Patented Oct. 29, 1957 bottom sections flanking said centrally extending rigid tooth not shown here; 6 indicates the upper and attached section of said tooth where it had been formed; 7 indicates the longer cut out, while 8 indicates the shorter cut out of said mid-section at the two sides of said tooth extending behind said razor blade; 9, 9 indicate the hinge sections of said bottom clamping part of said clip which receive said hinge sections of said upper part of said clip; 10 indicates the riveted ends of a rod which holds the several parts comprising said spring tension clip, including a coil spring, together in their mechanical assembly; 11 indicates the upper, solid side of said curved combwhich is especially made to fit said curved clip of my invention; 12 indicates the side guard teeth of said comb, while 13 indicates the teeth of said comb; 14 indicates the inwardly projecting prongs, as shown in Fig. 2; 15 indicates the safety-razor blade; 16 indicates the perforation at the center of said blade where it is clampingly held, after being inserted as shown in Fig. 3; 17 indicates the curved attachable handle as it would be held at the one side of the back of the head and affording the operator an unobstructed view at the opposite side of said head or neck when making use of two mirrors, the one to look into and having the other mirror at the side or at the back of the head; 18 indicates the larger end of said handle, while 19 indicates the narrow portion of said curved handle at the attachable end; 20 indicates the shoulder at this end, while 21 indicates the tapered tongue extending from this end of said handle, said latter being received, alternatively, and held by said two groups of arched and tapering band-loops as shown; 22, 22 indicate two cut out sections showing the depth of said han dle. In Fig. 2, 29-A indicates the elongated, rigid tooth itself; 23 indicates the stem end of the coil spring at this one side of said'clip; 24 indicates the coil spring of said clip, in the cut out; 25 indicates the cut out in said inwardly curved bottom midcenter of said bottom part of said clip, thus also severing it into two sections, this condition being needed to receive said upper vertically extending section of said rigid tooth and thus to permit the closing of said clip when said latter is not assembled as shown in this Figure 2; here too it can be seen that said severed and inverted bottom edge 26, 26 is arched inwardly to fit correspondingly, with the outwardly curvedupper part of said clip; 14, 14 shows the two inwardly formed prongs extending at the sides of said upper clamping part of said clip, said prongs serving to engage the end perforations of said double edged safety-razor blades thus checking their side movements when said blades are used in the assembly of said clip; 27 indicates the arched edge of said tooth while 28 indicates the straight edge of said tooth, said arched side being positioned between teeth of said comb to keep said clip in a straight position when moved up or down upon said comb for longer or shorter hair trimming; here too, in this figure should be particularly noticed the dissimilarity in the length of the two clamping parts of said clip of my invention. In Fig. 3, 29 indicates in the enlarged assembled section of said upper part of said clip the pointed end of said rigid tooth and showing that it terminates beyond said edge of said razor blade when fully inserted; here too can be seen the procedure of inserting said blades: thus the point of said tooth 29, being inserted through the midcenter perforation of said blade 16, 16, makes its way easily between blade sections 15-A and 15-B. In Fig. 4, 30 shows the enlarged rigid tooth in its flat stamped, or blanked condition before it is formed. In Fig. 5, 31 shows said tooth in the process of being formed into a vertical and somewhat lower position. Fig. 6 shows a view of my invention as one would see it on looking down from above Fig. 1, thus showing the curvatures of said blade clamping parts and of said handle.

Having described my invention I claim:

1. In a curved spring tension clip and attachable curved handle hair trimmer; said. clip in its assembly making, use of a double edged safetynabor blade, and a curved; small comb especially made to fit said clip; said clip comprising two dissimilar clamping parts the upper part being considerably longer than the bottom part, and said upper part having a longitudinal concaved condition, said bottom and; shorter clamping part having and being in a .convexedcondition, so that'when said bottom clamping sections of said two clamping parts come together they fitloppositely into one curve; said condition of saidcurved' clip and'said'curvedhandle,corresponding with the curvature of the back of. the head; nape and neclc and; thus making for better andeffic'ient-hair trimming;saidcurved upper part of saidcli'p having a cut out, severed section positionedi atits: bottom end; said out out having an elongated, rigid tooth extending through the. center and beyondthe two severed sides it is flanked by; saidelbngated;
