Definitions

  • the object of the present invention is to elim inate these drawbacks.
  • the dry shaving apparatus which is provided with an oblong hollow outer cutter secured to a handle and with pivotally displaceable flaps for closing th'e lateral openings of the shearing head as well as with an inner cutter which is arranged in the outer cutter and is longitudinally reciproca ble, is distinguished in that the closure flaps are asso ciated with means which permit of opening and closing the closure flaps in an easy manner with one hand only by the person using the apparatus.
  • This means is, advantageously, so arranged that with the same fingers as used for actuating said means also the fa'stening'device for the shearing head can be controlled or that said means operates with the shearing head fastening device directly in order to either open by the same fln ger movements onlythe closure flaps as desired or by slight additional movements of the fingers open the shearing liead fastening device at the same time, for the purpose of removing the shearing head from the handle.
  • FIG. 1 shows apartial elevation of the dry shaving apparatus inclusive of the shearing head as seen from the side of the apparatus;
  • Fig. 2 shows a crosssection of the shearing head
  • Fig. 3 shows a cross-section of the shearing head closure on theline III-III in Fig. 1;
  • Fig. 4 exemplifies another embodiment in a perspective view of the upper part of the dry 'shaving apparatus inclusive of the shearing head;
  • Fig. 5 shows a partial elevation of a further embodiment;
  • Fig. 6 shows a sectional elevation of still another embodiment
  • Fig. 7 is an elevation similar to'Fig. 6 with the flaps and pivotal finger pieces in position for removing the shearing head;
  • Fig. 8 is an interior view of a pivotal finger' piece and the associated closure flap
  • Fig. 9 is a perspective view of a latch of the shearing head fastening device
  • Figs. 10 and 11 illustrate a still further embodiment in two similar sectional elevational views with parts in two different operating positions
  • r Fig. 12 is a perspective view of a latch for the shearing head fastening device.
  • the numeral l designates the handle of the dry shaving apparatus to which is s'ecuredby means of bolts 2 an oblong hollow outer cutter through the intermediary of a fastening device.
  • Two such bolts each having a groove-3 and a convexed end 4 are arranged in the shearing head in symmetrical relation thereto.
  • This device includes fastening sleeves 5 each carrying a recess 6 and an associated latch l the outer end of which is bent over so as to form a control button 8 which buttons project out of the handle on the narrower sides thereof.
  • the latches I surround the fastening sleeves 5 (Fig. 3) by engaging in the recesses 6 thereof and are: pressed outward by the action of compression springs 9.
  • the outer cutter is composed of a shell Ill and a bottom piece ll. These two parts form together a tubular oblong body which is open at both of its ends. In the interior of said. body is guided in a groove II in the bottom piece ll an inner cutter 12 having a headed top l3.
  • outer cutter is provided with gaps l4 between the cutting teeth in a manner known per se.
  • the outer surface of the outer cutter and the headed top of the inner cutter are arcuately convex as regards the longitudinal direction and have a V-shaped transverse cross section.
  • the inner cutter oscillates in an are described about a centre C.
  • a cover plate I5 is arranged which is provided withhinges I6 that are positioned at the narrower sides of the handle in symmetrical relation to each other.
  • hinges flaps l1 are connected for pivoting movement thereabout, which flaps in their normal position shut in the inner cutter at both narrower handle sides by action of springs i8 for allowing this cutter to function as a hair catch so that the hair cuttings are retained in the interior of the handle.
  • the flaps l1 are provided with lever arms I! that are provided with pivots at 20.
  • Stirrup shaped finger pieces. 22 are held at one end by these pivots and at the other end in grooves 2
  • the finger pieces are pushed outward by the springs l8 so as to act upon the lever arms I9 of the flaps I1 by means of the pivots 20 and blowing them out.
  • the embodiment shown in Fig. 4 differs from the preceding embodiment by being devoid of a finger piece for Joint actuation of the flaps l1 and the latch control buttons 8.
  • the lever arm l9 which by action of a spring I8 is forced outwardly has such a length as to permit of being actuated for. pivotally displacing the flaps i1 by the respective fingers directly.
  • Such an arm is positioned on both sides so close by the latches 8 that joint control of the two latches is possible with corresponding finger parts; 1
  • a further possible modification might consist in making the lever arms It of the finger pieces I! in such lengths that in depressing said arms these can bear against the latch controlbuttons 8 directly.
  • Fig. 5 shows a further modification which, instead of flaps II, as shown in Figs. 1 or 4, has arranged at both narrow. sides of the shearing head a sliding latch 25 which is retained .in a guide 26 of the cover plate l5, The latches 25 are provided with lobes 21 having oblique faces 28. In the position of the control latches as shown the respective shearing head opening is closed. If then the latch is pushed downwardly into the dotted line position as indicated by the ⁇ is uncovered. In further displacingthe control latch the oblique face 28- on the lobe 21 forces the control head 8 on the latch inwardly whereby the shearing head locking device is released.
  • a fifth embodiment as shown in Figs. 6 to 9, means are provided by control of which the flaps are moved into an open position appropriate for removing the hair cuttings without the possibility of influencing the shearing head fastening device, this influencing being feasible in another position of the flaps.
  • the pivotal closure flaps are advantageously mounted for rotation in the pivotal finger pieces for con- 0 trolling the same, in which way the manufacture of the control means for the closure fiapsis simplified and cheapened.
  • the mounting of the control means is so carried into efiect that in slots which 5 have inner open ends and are arranged in the side walls of trough shaped pivotal finger pieces a .bent of! lower art of the closure flap is inserted.
  • the outer cutter iii, the gaps, it between the cutting teeth, the connecting bolts 2 inclusive of thegrooves 8 and the convexed ends 4' thereof, the fastening sleeves 5 inclusive of the recesses 6 thereof, and the instant inner cutter which is however not shownin the drawing are of the same construction as in the pre ding embodiments.
  • the cover plate It of the handle I is provided at its longitudinal ends with apertures at which constitute twov stop shoulders 81 and '82.
  • the latches or slides cooperating with the grooves 3 have two terminalupstanding projections 33 and are forced outwardly by coiled wire springs 34'.
  • the pivotal closure fiaps l I are rotatably mounted in the finger pieces 22'- for Said pieces are of trough like form.
  • the slide 1" is provided with longitudinally reciprocable relation to the oblong hollow portion of said outer cutter, pivotal closure flaps arranged on said shearing head at the sides of said handle adjacent to the longitudinal a hand as used in shaving with the apparatus, and
  • a depending ledge 42 instead of projections 33" and the side walls of the pivotal finger piece ll' are provided with recesses 43 into which the ledge 42 engages when the pivotal finger piece is forced inwardly into the position shown.
  • Fig. 11 for the purpose of opening the closure flap ll.
  • Fig. 10 shows the closure flap Il' in closed position. If it is desired to remove the shearing head the closure flaps Il' are furtherpivotallydisplacedas in the preceding embodiment. By this'means the spring 39 being pushed inward by the part 38101 the flap l1 cooperates with the ledge 42 so as to displace the slide 1" inwardly.
