MACHINE FOR SHARPENING TAILORS WAX.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed July 3, 1911. Serial No. 636,638.

1 '0 all whom it may concern Be it known that we, Ran A. EDGERTON and SIMON DINovsKY, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improve ments in Machines for Sharpening Tailors lVax; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the referencenumerals marked thereon, which form part of this specification.

Our present invention relates to an improved machine for sharpening tailors wax.

Our object is to provide a machine that will have a device for holding the wax and bringing it into engagement with proper cutting members whereby the wax is safely conveniently and quickly sharpened.

A further object is to provide means whereby the wax after each stroke of the moving member will be fed into engagement with the guide-way so that another shaving may be removed by the cutters at the next stroke.

Another object is to provide automatic means for releasing the hold of the support and the pressure of the feed device after each stroke so that the wax may be removed from the machine without furth r movement by the operator and the machine will be in position to receive another piece of chalk.

A further object is to provide a feed pressure device that will adjust itself to pieces of wax of varying width. I

Fig. 4 is an end view of the sliding carriage and wax support. Fig. 5is aplan view of another form of a machine embodying our invention. Fig. 6 is a side elevation of the same. Fig. 7 is a vertical cross sectional view on line 7-7 of Fig. 6. Fig. 8 is an end view of the bracket and its attached wax support.

Referring to the drawings in a more particulardescription and referring first to the form of machine illustrated in Figs. l1, there is shown a platform 10 preferably forming the top of a box 11 in Which may be placed an open-topped drawer 12 into which the shavings of wax may fall through the central opening 13 in the platform 10. Above the latform opening 13 and supported by brldges 1d are placed two parallel and longitudinally arranged guides 15 havmg their opposing faces slanting toward each other at the bottom to form a V-shaped guide-way 16 to receive the wax 18 and of substantially the angle of the wax when sharpened. Suitably mounted in each of these guides 15 and slightly projecting therefrom into the guide-way 16 are cutting members'17 of any desired form and having their cutting edges so shaped and so placed with reference to each other as to shave the wax 18' t0 the desired angle.

Slidingly mounted upon the

guides

15, 15, 1s a carriage 19 retained on said guides by overhanging sides 19 engaging the outer sides of the guides and by flanges 19 engaging the bottom of said guides but of such projecting length as not to come into contact with the bridges 14. From the top of said carriage rises a longitudinally arranged upright 20 having its end 20 toward the right as viewed in Figs. 1 and 2 extended downwardly in a V-shaped pointinto the guide-way 16 and forming a contact support for one end of the piece of wax 18 and adapted to support substantially that entire end of the wax as it is shoved toward the right past the cutters 17 by a movement of the carriage 19.

Pivot-ally mounted upon the upright 20 at 21 is an arm 22 extending to the right of the upright 20 to a point about midway of the piece of wax 1S, and having at that end a V-shaped finger 23 overhanging the guideway 16 and the wax 18 therein and adapted to press down upon the top of the wax under the tension of a spring 24 suitably mounted upon the upright 20. The left hand end 22" of the arm 22 projects beyond the pivot 21 and the upright 20 and, as the carriage is moved to the extreme left end of the guides 15, this end 22 comes into camming engagement with the under side of a fixed slanting arm 25 secured to the guides 15, and is thereby depressed causing the other end of the arm with its finger 23 to be raised from the wax as indicated in dotted lines in Fig. 2. Centrally and horizontally pivoted upon the carriage 19 at 26 is another arm 27 having one end 27 reaching past the wax and then turned in at right angles across the guide-way 16 just beyond the farther end of the wax. A spring 28 upon the carriage 19 is tensioned to keep the end 27 across the guide-way. The object of this arm is to have the end 27 draw the wax back past the cutters 17 on the backward stroke of the carriage and to keep it in close contact with the support 20 so that there will be substantially no lost motion when the next forward stroke is taken. In order to release this holding arm from contact with the wax so that it may be easily removed when sharpened, the end 27 is withdrawn from position across the guideway 16 at the end of each return. stroke by the other end 27 of the arm being brought into camming engagement with a projection 29 at the left end of the guides 15 so that the arm 27 is moved to the position indicated in dotted lines in Fig. 1. At the inner end of the camming edge 27 there is provided a recess 27 allowing the end 27 to spring out part way and engage the projection 29 and hold the carriage in the extreme left position against the tension of both springs 24: and 28. In this position it will be obvious that the finger 23 and the end 27 pf arm 27 are out of engagement with the wax so that the wax already sharpened may be removed without further movement of the machine by the operator and a new piece may be inserted preparatory to sharpening. It will be understood that after each sharpening and in fact after each return stroke the machine will be brought to this locked position.

Assuming that the wax to be sharpened has been inserted in the guideway close to the support 2O the operation of the machine will be as follows: The initial forward movement of the carriage by means of the operator manually operating the handle 30 at the top of the upright 20, will cause the projection 2) to ride over the rearward sloping side of the locking recess 27. As the carriage is farther advanced toward the right the arm 22 will be released from its camming engagement with arm 25 and under the tension of spring 24 the finger 23 will press the wax 1S firmly down into the guideway 16. At the same time the arm 27 will have been released from engagement with projection 29 and under the influence of spring 2 1 the end 27 will have passed around the forward or right end of the wax, steadying the wax during forward movement of the carriage and in position to draw back the wax with the carriage upon the return stroke. A further forward movement of the carriage carries the wax past the cutting members 17 which preferably being several in number on each side of the wax will take off several thin shavings therefrom. A stop 31 upon the guide 15 arrests the forward movement of the carriage after the entire wax has been moved past the cutting members. Upon the backward stroke the wax is carried back past the cutting members by means of the end 27 of arm 27 and at the end of the return movement the finger 23 and arm 27 are locked out of engagement with the wax. Successive forward and backward strokes are made until by the feed of the wax by the spring pressed finger 23 and successive shaving of the wax by the cutters, the desired edge is produced upon the wax.

It will be understood that the shavings of wax will be saved to melt over into new forms and that this saving will be encouraged. by providing a machine which will so quickly and effectively sharpen the wax without danger of the person cutting his fingers.

Within the drawer 12, may be mounted a swinging partition 32 operated by a handle 33 projecting without the drawer. By means of this swinging partition the shavings of wax may be kept separate from the shavings of chalk sometimes used by tailors. It will be understood that the operation of our machine would be the same with wax, chalk or any other similar material and that we have used the term wax as including any such material.

Referring now to the form of machine illustrated in Figs. 58, it will be seen that, instead of stationary guides holding the out ters against which is carried the wax by a carriage slidingly mounted. on said guides, the wax support is stationary and the guides and cutters are moved past the wax. As the details of this construction and the principle of operation thereof are so near alike, a detailed description of the parts is not deemed necessary except where they vary from the first described form.

Upon the cent-rally slotted platform 10 are provided metal tracks 3 1 having upturned ends and 36 at right and left ends respectively viewed in Figs. 5and 6. Slidingly mounted on these rails 34L- by means of legs 37 and rollers 40 are the guides 15 having the V-shaped guide-way 16, cutting members 17 and slanting arm 25 and projection 29 as heretofore described. Fixed to the platform 10 is a bracket 38 projecting over the guide-way 16 and affording support for the upright 20 and its supporting front edge 20 and to which bracket is pivotally secured the arm 27 and spring 28 as and for the purposes already described, while to the support 20 is pivoted the arm 22 with its operating spring 21 and forked finger 23 as already described. Fixed to the guides 15 is a handle 39 by which the operator will shove the cutter holding guides back and forth past the fixed bracket 38 holding the wax. It will be obvious that the motion to the left will now be the cutting stroke and the motion to the right will bethe return stroke but it will be apparent that the resulting operation will be equivalent except that themachine will be brought to locked position with arms 2% and 27 released at the end of the forward movement instead of at the end of the return movement. The spring tensioned feed will be operative as before to feed the wax into the guideway as needed. The upturned ends 35 and 36 of the track 3% serve as backward and forward stops limiting the movement of the sliding guides by contact with the rollers 40.

It will be noticed that the V-shaped guideway 16 is not closed at the bottom but open by reason of the guides 15 being slightly spaced apart, and this arrangement permits any shavings of the wax that get into the guideway to fall through the open bottom or be easily shoved therethrough at either stroke instead of clogging up and breaking the wax. Ordinarily most of the shavings will fall from the cutting members without lodging in the guideway which is cut away near the cutting members for that purpose, as indicated in Figs. 3 and 7.
