SUSPENSION APPARATUS FOR ELECTRIC HAIR CLIPPERS.

Application filed:ctober 13, 1921. Serial No. 507,439.

To all whom it may concern: 7

Be it known that I, LEE ALBEREL CAN- NADAY, a citizen of the United States, and a resident of Fairburn, in the county of Campbell and State of Georgia, have invented certain new and useful Improvements in Suspension Apparatus forElectric Hair Clippers, of which the following is a specification. I

This invention relates to a suspension apparatus for electric hair clippers or the like.

The object of the invention. is to pro,-

vide an apparatus of the above character adapted to be secured to a ceiling or the,

like for movably suspending: an electric hair clipper or similar appliance, in such a manner that'one clipper may serve. several rangement of parts will" hereinafter appear in the detail description to follow.

The invention is illustrated by way of example'in the accompanying drawings, in which; 1

Figure 1 is a perspective view of the apparatus when fully assembledand suspended 4 from a ceiling,

Figure 2 is a detail vi'ewof'the clipper supporting hooks, J 7

Figure 3 is a side elevation ofthe carriage, V

Figure 5is a side elevation ofthespring motor for supporting cableythe housing therefor beingshownsin longitudinal; section, a

Figure 6 is an elevation of one end of the control drum of the spring motor, 7

Figure 7 is 'a vertical longitudinal sectional view of the control drum,

Figure 8 is a side elevation of the spring 55 winding plate,

as at 14t to provide the legs 15. each pair of extensions 13 occurrlnglat corthe drum the-re extends a shaft 25. the end of theshaft 25 associated with the cross member 23 there is fitted a collar 26 c Figure 9 is an inside elevation of one end of the spring motor housing,

Figure 10 is a view similar to Figure 6, but of the oppositeend of the drum.

, Referring to the drawingsmore particularly B indicates a pair of brackets which are secured to a, ceiling or the like indicated by the dotted line 10 Figure 1; T. a rod or track which supports the carriage G; and which in turn has secured thereto the spring motor M.

The brackets B are preferably L-shaped as shown and which may be secured to the ceiling 10 in any suitable manner. The ends of rod or track T extend through the free ends of the brackets B and each end has threaded thereon a wing nut 11 adapted to permit the rod to be removed and also for holding the rod against longitudinal movement.

The carriage 0- consists of a channel frame 12, the side flanges of which have formed at each endan extension 13 while the bridge portion is longitudinally recessed Between responding ends of the channel frame member 12 there is journaled a grooved wheel 16 adapted to run upon the rod or track T. Also between each pair of extensions 13 there is securedforward of the associated wheel 16, a thimble member 17 bythemeans of a bolt 18, each thimble supporting a bumper 19 of rubber or the like.v t

The spring motor M comprises a drum generally-indicated by ,the reference ,numeral 20 which has formed in its one end a recess 21 and has its other end hollow as at 22. The hollow endof the cylinder is formed with a cross plate 23 andthrough the cross plate 23 and solid portion 24 of Upon which is formed at its inner end with a radial flange 27. The drum 20 is formed with'the retaining flanges 28 and 29, the flange .28 being of the greatest thickness and offset upon its, inneredge as at 30, at

c which point the drum'has threaded thereis a circular plate 36 which is formed with a nipple 37 adapted to journal the associated end of the shaft 25. in the nipple 37 there is fitted a plug 38 having a squared end 39 adapted for receiving a key for rotating the plate 36. The plate 36 carries a pin lO which is adapted to be extended into a loop ll secured to the outer end of the spring 34-.

The drum 20 is mounted in a housing com prising a casing l2 which is preferably square in cross-section and which is formed with a longitudinal slot in the lower side thereof, through which the cable 33 may extend. Each end of the casing has titted thereon a cap as. and each cap is formed with an outwardly depressed portion l-l. in the depressed portion A of the cap adj acent the end cross member 23 of the drum there is fitted a bushing which journals the corresponding end of the shaft lhro-ugh the depression -14 of the other cap extends the nipple 37 of the plate 36 and between the plate 36 and associated rap leis interposed a ratchet 4:6, said ratchet being loosely fitted upon the nipple 37 and held against movement with respect to the shaft 25 by the screws 47. Upon the outer face of the plate 36 there is pivoted a pawl 48 which is pressed by the spring 4-9 for operatively engaging the ratchetl6 and limiting the plate to rotating in one direction.

Upon the inner face of the housing cap ll supporting the bushing a5 is pivoted a latch 50, the portion 51. of said latch h ving its and its forward edge beveled as at 58. The portion 51 of the latch is also covered with hard rubber or the like. The latch is adapted to cooperate with the pins extending from the adjacent end of the drum for holding the drum against rotation in a manner which will later be described.

Referring to Figures 1 and 2 the cable has its free end extended through one passage of a twin-sleeve 54- thcn through the inner edge formed with a notch v.2

swivel member55 of a snap hook 56, and

then extended into the remaining passage of the twin-sleeve for securing the same. The twin-sleeve is also formed at its upper end with a pair of ears 57 between which there is pivoted the shank of a hook 38.

The operation of the present apparatus is as follows: Assuming that the apparatus is suspended from a ceiling as shown in Figure 1, and that the track T extends over several barber chairs. The handle of an electric clipper is flexibly attached to the snap hook 56 and the clipper is hung upon the hook 58. A key is used to wind the spring 34 to such an extent that the drum 20 will rotate for winding the cable 33 so that the clippers suspended by the cable will be clear of the workmen therebeneath. When it is desired to use the clippers the same are grasped by the operator and pulled down to the proper level against the tension of the spring 3%. Upon the clippers being brought to the proper level the latch 50 will engage one of the pins 52 and hold the drum against rewlnding movement. lVhen the workmen are through with the clippers by pulling down upon the cable 33 and then quickly releasing the same the tension of the spring 3-: will carry the pins 52 over the notch 52 and rotate the drum in a reverse direction for rewinding the cable sufficiently to raise the clippers above the heads of the workmen and so retain the same. VFhen another barber wishes to use the clippers he grasps the same and moves the carriage C to proper position and then repeats the operation just described for lowering and raising the clippers.

lVhile l have shown and described the to be understood that T are well aware that the construction, combination and arrangement of parts may be changed by those skilled in the art without departing from tl e spirit of my invention as indicated by the appended claims.

I claim .1. In an apparatus of the character described, a casing, a shaft rotatably supported therein, a drum supported upon said shaft, a winding spring in one end of the drum having its inner end secured to the shaft, a plate rotatable upon said shaft and having the outer end of said spring secured thereto, means whereby said plate may be rotated for tensioning said spring without rotating said drum, and latch means for retaining the drum against rotation in a direction influenced by the tensioning of said spring.

2. In a device of the character described, a casing, a shaft rotatably mounted therein, a drum carried thereby, a winding spring Within the drum and having its inner end secured to said shaft, a plate rotatable upon the shaft and secured to the outer end of said sprin means whereby said plate may be manually rotated in a direction for tensioning said spring, pawl. and ratchet means between said plate and easing adapted to hold the plate against rotation in adirection for unwinding said winding spring, and latch means associated with said winding drum to hold the same against rotation under the influence of said spring.
