HUGO LUENSE, or CHICAGO, ILLINOIS.
ELEGTRICALLY-AOTUATED HAIR AND WOOL CLIPPER.
Specification of Letters Patent.
Patented Feb. 2, 1909.
Application filed March 5, 1908. Serial No. 419,271.
To all whom it may concern:
Be it known that I, HUGO LUENSE, a subject of the Emperor of Germany, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electrically-Actuated Hair and Wool Clippers, of which the followin is a specification.
his invention relates to improvements in electrically actuated hair and wool clippers and among the salient objects of'the invention are to 1provide an extremely compact and powerful e ectric motor to which the cli ping lad-es are directly attachedwithout t e intervention of the usual flexible shaft, thus forming a hand tool; to provide a motor construction which exposes the Windingslargely to the outer air and thereby prevents overheating; to provide a construction which may 'be quick y taken to piecesforinspeotion, adjustment or repair; to provide certain features of adjustment of those parts most susceptible to wear; to provide an improved hooded or protected illuminating attachment which throws a beam of light upon the cutter, thus enabling the device to be used in dark stables and the like, and in general to pro vide an improved device of the character referred to.
To the above ends the invention consists in the matters hereinafter described and more particularly pointed out in the appended claims.
The invention will be readily understood from the following description, reference being had to the accompanying drawings, in which' Figure 1 is a view chiefly in longitudinal vertical section, certain internal parts being, however, shown in elevation; Fig. 2 is a transverse sectional view taken approximately on line 22 of Fig. 1, and looking in direction of the arrows. Fig. 3 is a crosssectional view taken on line 3-3 of Fig. 1, and looking in the direction of the arrow. Fig. 4 is a top plan View of the device. Fig. 5 is a sectional view taken on the interior line 55 of Fig. 1, and looking in the direction of the arrow. Fig. 6 is a diagrammatic view showing the circuit connections. Fig. 7 is a detail view of one of the brush tubes. Fig. 8 is a transverse sectional view taken through the two cutter plates.
Referring to the drawings, 1 and 2 desi nate respectively upper and lower po e plates of iron extending transversely and between which are interposed and suitably secured the core pieces 3, 3 which support the field windingsd. To the rear edges of the plates 1 and 2 is secured by suitable tap screws a hollow casting 5 refer-ably made of aluminum so as to be lig t, and to the forward edges of the same plates is similarly secured a second hollow casting 6, also preferably of aluminum.
W ithin and across the rear end of the hollow casting5 is arranged to extend avertically disposed supporting bar or web 7, through which is formed an aperture 8 to receive a sleeve or bushing 9 within which, in turn, is journaled an armature shaft 10 of the armature. Just in the rear, '21. 0., outside of the support 7, is mounted upon the bushing 9 an insulating support 11 w ich carries a pair of diametrically opposite longitudinally disp osed brush tubes 12 (see detail 3).
he outer end of each tube is closed an contains a coiled expansion spring which acts against a carbon brush or pencil 13 mounted within the tube and held yieldingly in hearing with the commutator tube 14 of the armature. The support 11 is ca able of rotary adjustment to give the brus proper adjustment.
The front casting 6 is provided with a relatively thick front end wall 15 provided with two apertures adapted to receive slightly eccentric journal bushings 16 and 17, respectively. These bushings are driven into their seats tight enough to hold them against movement, but, nevertheless, may be forced out and rotated sli htly to change the relations of the journal caring apertures to each other. The bushing 16 receives the front end of the armature. shaft 10, as shown clearly in Fig. 1, while the lower bushing receives a short shaft 18 carrying at its outer end an eccentric wrist 19. The armature shaft carries a gear 20 which meshes with the corresponding gear 21 on the shaft 18.
The eccentric wrist 19 engages a vertical eccentric slot 22 (see Fig. 5), formed within a casing 23, which is rigid with the upper side of the reciprocating cutter blade 24; the arrangement being such that rotation of the shaft 18 imparts a short reci rocatory movement to the cutter blade. he fixed cutter blade 25 is rigidly secured to the lower side of the casting 6 by means of suitable screws (not shown) and the reciprocating late is confined and guided by means of gui e studs 26 rigidly mounted in the lower cutter blade extendin up through suitable slots in the movable blade and through overlying clamping plates 27. These 0 ampingplates are held in yielding bearing with the movable blade by means of coiled s rings 28 interposed between the upper si es of the plates and the thumb nuts of the respective studs 26. Antifriction rollers are interposed between the reciprocating plate and the overbeing detachably united with the motor frame by means of a screw 36, being provided at its opposite end with a screw clamp 37 whereby the conductor cord may be clamped so as to prevent pulls which may come upon the cord from being transmitted to the con nections of the conductors with the motor and lamp.
The circuit connections are clearly shown in the diagram Fig. 6, as well as being indicated in the other figures of the drawings.
