Title: Improvements in or relating to a hair or other brushes
IPC: A46B7/02
Filed: 1955-08-25
Abstract: 794,594. Brushes, handles. BAUDOUIN, J. Aug. 25, 1955 [Aug. 25, 1954; July 19, 1955], No. 24453/55. Classes 19 and 61. A brush is provided with a perforated plate through which the bristles may pass and with resilient means for urging the brush base to a retracted position with respect to the plate, the arrangement being such that by a simple movement of the hand the bristles may be moved to a projected position for use. The movement of the plate along the bristles may serve to clear hair or other matter from the brush. Fig. 2 shows a brush comprising a base plate 1 carrying bristles 2 a perforated plate 4 having a rim 8 and an elastic cover 7d. When the brush is pressed against the object to be brushed the bristles project through the perforated plate and on ceasing brushing the bristles return, the movement being cushioned by the necessity to draw air through the perforations. In Fig. 6 the brush is arranged telescopically inside the perforated member 4 and urged to a retracted position by a spring. In Fig. 7 the two parts of the brush are connected by a spring 7c, 7d forming a handle and which when pressed together by the hand cause the bristles to emerge through the perforations. Fig. 13 shows a further embodiment in which the brush 1 is normally retained within the body of the brush by a bow spring 10. By operating the handle 34 the bristles are moved forward into the position of use and the members 29 and 33 are such that the bristles are locked in position. Upon releasing the lock by pressing the opposite end of the handle the bristles return to the original retracted position. Fig. 12 shows a brush in which the bristles are supported on a spring 10 secured to the ends of two transverse arms 13, 14 located in slots in the sides 22 of the perforated member and spaced by a spacer 18, the whole being enclosed in an elastic member 24 and being such that the brush in its normal position is within the holder. Pressure applied to the sides of the brush causes the brushing element to move forward to the position shown whereupon a ball 16 rolls beneath the spacer to lock the brush element in position. To retract the brush element pressure is applied to the sides of the brush which is then tilted so that the ball rolls away and permits the brush element to return to the retracted position. The bristles may be silk filaments, bristle, horse hair, wire, vegetable fibre or a synthetic material such as a super-polyamide.

Filed: 1932-09-02
Abstract: 406,703. Selective perforating-machines. CREED & CO., Ltd., and GRIFFITH, R. G., Telegraph House, Croydon. Sept. 2, 1932, No. 24497. [Class 31 (ii).] In a keyboard apparatus for the transmission of current impulses to a line or the perforation of tape in accordance with the code elements of a signal, a series of permutation bars is set for the case-shift signal combination on depression of a shift lever, which, on release, effects the setting of the bars for the reshift signal. The keyboard mechanism is arranged so that, in the extreme positions of the case-shift lever, the permutation bars are free to be moved by the depression of any of the signal keys. On depression of the shift key lever 6, which is always out of engagement with the bars 1 ... 5, a tooth 14 on a T-shaped lever 12, pivoted on an extension of the shift lever, engages a tooth 16 on a pivoted actuating bar 8, which engages inclined cam faces on the bars 1 ... 5 to effect their setting for the shift signal. Before the lever has completed its normal downward movement, an extension 18 of the T-lever engages a stationary pin 20 through which the tooth 14 is rocked out of engagement with the bar 8 which under the action of a spring 23 moves out of operative relation with respect to the bars 1 ... 5. Simultaneously, a tooth 15 moves into an actuating position with respect to a projection 17 on the reshift actuating bar 9. On the release of the key lever 6, the bar 9 engages inclined notches in the underside of the bars 1 ... 5 and effects their setting for the reshift signal. When the key-lever approaches the limit of its upward travel, the extension 18 engages the pin 19 rocking the tooth 15 out of engagement with the projection 17, then allowing the bar 9 to be moved by the spring 23 out of engagement with the bars 1 ... 5. Simultaneously, the tooth 14 is rocked into an engaging position with respect to the tooth 16 on the bar 8. The shift-lever 6 may be operated and locked, or solely locked subsequent to its independent actuation, by a locking lever 7 carrying a pin 24 co-operating with a slot in one arm of a pivoted member 25, which engages a pin 26 to lock the shift-lever 6 in the depressed position. To remove the shift-lock, the key lever 6 is further depressed and the pin 26 rides on an inclined surface 27 to remove the member 25 out of engagement with the pin 24, whereupon the lever 7 returns to its normal position in which it permits the lever 6, on release, to return to its normal position. Specification 388,785, [Group XL], is referred to.
