CLIPPER.

SPECI-FlCATION forming part of Letters Patent No. 621,674, dated March .Q1-,51899.

Application filed May 2, 1898. Serial No. 679,446. (No model.)

To all whom t may concern.

Be it known that I, EDWARD S. HoToHKIss, a citizen of the United States, residing at Bridgeport, county of Fairfield, and State of v Connecticut, have invented certain new and useful Improvements in Clippers, fully described and represented in the following specication and the accompanying drawings, forming a part of the same.

The object of the present invention is to provide an improved construction of clipper.

The invention relates especially7 to improvements by which a toilet hair-clipper is provided that is simple in construction while easy and efficient in operation and so arranged that adjustment of the parts is convenient and that the clipper may readily be assembled and disassembled for ren ewal of parts or other purposes.

As a full understanding of the invention can best be given by a detailed description of a construction embodying the same, such a description will now be given in connection with the accompanying drawings, showing a toilet hair-clipper embodying all the features of the invention in the preferred form and a modified construction, and .the features forming the invention will then be specifically pointed out in the claims.

In said drawings, Figure l is a plan View of 'the clipper in its preferred form. Fig.` 2 is a side view of the same with-the handles broken away. Fig. 3 is a section on the line 3 of Fig. 1. Fig. 4 is a section on the line 4 of Fig. 3. Fig. 5 is a section on the line 5 of Fig. 4. Fig. 6 is a section on the line 6 of Fig. 3. Fig. 7 is a section similar to Fig. 3, showing a modified construction embodying certain features of the invention.

Referring now to the construction shown in plate, so as to hold this handle against turning on the pressure-bolt F, which in the construction now being described passes freely through asleeve 10, projecting upwardly from the body of the stationary handle C, and is screwed down into the bottom comb-plate A. The movable handle D is provided with the usual operating-arm 11, carrying a stud which enters the usual slot in the top of the movable comb-plate B for moving the latter, and the usual guide or stop pins 12, carried by the cap E and passing through slots in the rear edge of the movable plate and holes in the bottom plate A, are shown, the cap thus being held in proper position on the bottom plate. The body ofthe movable handle D is preferably milled out on the under side, as

shown, to form a circular groove, the inner wall of which forms a sleeve 13, inclosing the stationary sleeve 10, and thus forming a long bearing for the movable handle, and within the groove formed partially in the body porv stationary part of the construction, preferably to the stationary handle, as shown, the ends of the spring being simply passed through openings in the .respective handles or otherwise secured thereto, as usual in this class of constructions. It will be understood, however, that it is not essential to the present invention that the spring be inclosed, although this is preferable. Vhen thet'wo handles are assembled with the stationary plate, therefore, the sleeve 13 incloses the sleeve l0 and the latter forms a bearing for the movable handle and the two handles are secured to the bottom stationary plate A by the pressure-bolt F, which in the construction now being described is screwed into the plate A until the fixed collar 2 on the pressure-bolt is seated upon the top of the sleeve 10 of the stationary handle, this sleeve l0 projecting slightly above the movable handle, so as to avoid pressure of the collar 2 upon-the movable handle and permit the latter to move freely. These parts are then held firmly together by the pressure-bolt F, and the twisting of the handle C upon the bottom plate is IOO prevented by studs 1 passing through the openings in the latter on the opposite sides of the pressure-bolt.

In the construction shown, in which the opening in the plate 13 for the stud on operating-arm 11 is closed at the rear, the movable comb-plate B is put in place before the handles are thus secured to the stationary plate A; but if this opening extends through the rear edge of the plate B,as is also common, it will be understood that the movable plate B may be slipped into place after the handles and bottom plate are thus assembled.

The cap E rests upon bearing-surfaceslll, formed on the stationary handle rearward of the pressure-bolt F, so as to secure the required leverage for the pressure of its front Aedge upon the top of the movable comb-plate B, an antifriction ball-bearing device being preferably employed, which ball-bearing device will be fully described hereinafter and formsapart of the presentinvention,although it will be understood that other features of the invention may be employed with the front edge of the cap E bearing directly upon the top of the comb-plate B or with an antifriction-bearin g of any other suitable form. The cap E is pressed downward, so as to secure the desired spring-pressure upon the movable comb-plate B, by a spring-washer nut upon the upper end of the pressure-bolt F, which may be of any suitable form. I have devised, however, an improved spring-washer nut, which is preferably used. In this nut construction the bearing-piece 15, or lower part of the nut, moves freely up and down on the screw portion of the bolt F above the cap E, and between the bearing-piece l5 and the nut proper,16,above it is inserted a spring-washer 3, the nut 16 pressing against the upper side of the spring-washer 3, so as to secure the spring-pressure desired. I preferably usea hub on the nut bearing on the washer and seat the washer within a recess in the top of the bearing-piece l5, as shown; but these features may be omitted. The upper edge of the bearing-piece 15 and the lower edge of the rim of nut 16 are provided with flanges 4, projecting, respectively, outwardly and inwardly from the portions on which they are formed, so as to overlap and thus hold the two parts of the spring-washer nut together, while at `the same time permitting movement of the parts on each other longitudinally of the pressure-bolt F. This construction provides a very simple and efficient spring-washer pressure-nut construction, in which there are no loose parts to be displaced or lost.

In the construction now being described, in which the pressure-bolt holds the handles on the stationary plate independently of the pressure of the cap, I preferably provide the cap E with a downwardly-projecting hub 5 on its under side, having an angular opening which fits'over a corresponding angular collar 6 on the pressure-bolt F, so that by the seating of this hub upon the, collar G the bolt is held positively against rotation as the friction-nut is turned down and the proper adju stment of the parts assured. It will be seen that in this construction the single bolt F secures all the parts together and forms the pressure-bolt, and this bolt passes through the bearing of the movable handle, so that the latter oscillates about it. A very efficient and durable construction is thus secured and the assembling and disassembling of the parts is convenient. i

Referring now to the ball-bearin g construction, which is preferably used, the cap E is pro-- vided on the under side of its forward or pressure edg'e with a groove or channel c, extending longitudinally of the comb-plates--that is, in the line of movement of the movable comb-plate-this channel preferably being formed by thickening the edge of the cap suitably and milling the channel through the edge. This channel is open on its under side and receives a ball-carriage 17, provided on its under side with pins 7, enteringholes in the top of the movable comb-plate B, so that the ball-carriage 17 moves with the comb-plate B. This ball-carriage 17 is provided with end blocks 8 and a center block 9, which form'between them runways for the balls I), these runways extending in the line of movement of the movable comb-plate and being of such length as to secure the proper action of the balls h as the carriage moves in the channel of the cap with the movable comb-plate.

The ball-carriage 17 is preferably secured to the cap E, so as to form a single part therewith for convenience in assemblingand disassembling of all parts and especially to avoid misplacement or loss of the balls. I secure this result, while at the same time permitting the free movement of the ball-carriage 17 in the channel of the cap, by providing a groove in the center block 9 of the carriage, which is entered by a screw c', which is tapped through the rear wall of the channel in the cap, so that this screw holds the ball-carriage 17 and the balls b in the cap when the latter is removed. The ball-carriage and balls may be readily detached from the cap by removing the screw c. It will be seen that in this construction the bottom plate of the ball-carriage 17 forms a bearing-plate which supports the pressure of the cap E, transmitted through the balls h, so that there Ais no wear upon the top of the movable comb-plate B, with the result that in case of wear on account of the ball action the movable comb-plate need not be renewed, but it is necessary only to renew the ball-carriage 17- or its bottom plate. The ball-carriage 17, movin gin the groove or channel e, also serves to guide the comb-plate in `its movement, the blocks S 9 forming with groove or channel c a guiding tongue-andgroove connection between the movable comb- Aplate and the pressure-plate formed by the edge of the cap E. This feature of a guiding tongue-and-groove connection between a clipper pressure-plate and the movable comb- ICO IIO

plate may be used without balls or other antifriction-bearings, and is thus claimed.

In Fig. 7 I have shown a construction employing a modified arrangement of the pressure-bolt and other parts of the construction. This construction is the same as previously described except that the pressure-bolt F is passed upward through the bottom plate A and sleeve l0, being provided with a head seated in a recess in the under side of the bottom plate A, and the handles are secured together and to the bottom plateAby anut 19, screwed downward upon the pressure-bolt F, which is screw-threaded inside the capE for this purpose, this nut I9 thus performing the functions of the collar 2 on the pressure-bolt F of the construction previously described.

In both constructions shown in the drawings and above described it willl be seen that the stationary handle is pressed upon the stationary plate Aby the cap E pressing upon the bearing-surfaces 14. This is not absolutely essential in these constructions, in which the handles are held upon the stationary plate by means independent of the pressure-cap; but in such constructions in which the handles are held upon the stationary plate independently of the pressure-cap the latter may be arranged to bear upon any other suitable tixed part of the clipper. In constructions in which the pressure-cap bears upon the stationary handle, as in the constructions shown, the parts may be held together by the single bolt F acting through the pressurecap, and while it is preferablel to employ a collar or nut on the bolt F, by which the movable and stationary handles are held on the stationary comb-plate independently of the pressure-cap, as in the constructions shown, and this feature forms an important part of the invention, it is possible to omit this feature and secure fairly good results, the pressure' of the cap E on the surfaces 14 of the stationary handle then holding the parts together, and the invention includes certain combinations in such constructions. If the collar or nut on bolt F be thus omitted, it will be understood that the cap E will not press upon the hub portion of the stationary handle, but will be separated from it a short distance, so as to permit the movable handle to move freely, but prevent the movable handle from working upward during operation.

i It will be understood that other modifications maybe made in the constructions shown -without departing from the invention as defined by the claims, and I am not'to be limited to the exact form or arrangement of any of the parts in the constructions illustrated.
