CHARLES F. PHILLIPS, OF ST. PAUL, MINNESOTA.

COLLAR-EDGING MACHINE.

Application filed November 11, 1918.

Z '0 all whom it may concern.

Be it known that 1, CHARLES F. PHILLIPS, a citizen of the United States, residing at St. Paul, 391 E. 6th St, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Collai Edging Machines, of which the following is a specification.

' This invention relates to improvements in collar edging machines and particularly to the type wherein the collar is held firmly on a form and the edging device is caused to roll over the edge of the collar.

One of the objects of the invention is to provide improved means for polishing the inner face adjacent the upper edge of the collar to render it smooth without polishing the top of the collar. A further object of the invention is to provide ironing means whereby the seam on the inner face ofthe neckband of the collar adjacent the upper edge thereof may be subjected to frictional action while the top of the edge is sub jected to a rolling action.

A further object of the invention is to provide improved means for edging collars without subjecting the collar to undue heavy pressure as is customarily the case.

The invention consists in the construction, combination and arrangement of parts hereinafter described and claimed.-

device and comprises a base 1 upon which are rigidly mounted collar supporting forms 2. The forms comprise cylindrical members axially vertically disposed and have a round ed upper edge 3. Rotatable in the frame and centrally disposed relative to said cylindrical members, is the shaft 4 carrying rigidly at its lower end the worm gear 5 and at its upper end the edging mechanism B.

Journaled at each of its ends in the frame A is a power driven shaft 6 rigidly carrying a pulley 7 whereby said shaft may be driven from any suitable source of power such as the motor 0.

In Fig. 1 is shown a pair of edging devices, the cylindrical members 2 being suitably separated on the top of the base 1, the two cylindrical members alining with the shaft 6 so that the worms 8 rotatable thereon mesh with the teeth of said worm gears 5 to drive the shafts 4: in a manner hereinafter to be explained. Since the actuating mecha nism for each of the edgers is similar, a single complete device will hereinafter be described, it being understood that any number of edging devices may be mounted on an extended base and driven from a single shaft such as 6, each edging device having its corresponding wormthereon. Slidably mounted on the shaft 6 by means of the feather 11 is the clutch member 12, having a median groove 13 and a laterally projecting pin 14 adapted to engage a similar pin 15 projecting laterally from the end of the worm, whereby, when the clutch 12 is slid toward said worm the engagement of the pins 14: and 15 will cause the worm to turn crank is adapted to movably fit with its outer end into the groove 15 of the clutch member so that when the bell crank is manually moved the clutch member will be slid along the shaft 6.

Integral with the clutch moving arm and projecting downwardly therefrom is a lug on the side of which is secured a spring arm 20. Pivotally mounted on the upper face of the gear 5 is the double ended tripping dog 21 adapted to engage said spring arm, as in dicated in Figs. 11 and 12, wherein (Fig. 12) the block is shown engaging the arm to push it outwardly, to move the clutchmember 12 out of engagement with the worm S.

In Fig. 11 the dog is shown in the position it assumes just after passing the arm, it being evident that in the next revolution of the wheel 5 the dog will assume the position shown in Fig. 12 as it will be engaged by he arm 2-0 to turn it from the position shown in solid lines (Fig. 11) to the position shown in dotted lines, same figure. Thus the clutch member is actuated each alternate revolution of the gear 5. The edging mechanism 13 comprises an extension member 22, set-screwed on the upper endof the shaft fi- Said extension member being formed with a pair of outwardly extended bosses disposed in horizontal alinement to constitute pivots 23. The upper portion of the extension member is formed with a stalling box, adapted to receive the gas supply pipe 23, the latter being surrounded by the threaded gland 24 which screws into said stalling box and is adapted to compress a packing surrounding said pipe to render it tight against leakage.

The extension member is also provided with a side gas outlet 25 which is in open communication with the pipe 23, so that gas may pass thcrethrough.

Mounted in the pivots 23 so as to swing in a vertical plane and extending upwardly and outwardly over the cylindrical form 2 is the housing D. The housing D comprises an open work circular casing 26, having a centrally mounted spindle 27 whereon is rotatably mounted the edging wheel 28.

Integral with the casing and extending downwardly and inwardly and journalcd on the pivots 23 are the arms 29. The arms 29 are symmetrically disposed about a radial line relative to the cylindrical. forms 2, the open work casing being joined to the arms at their outer ends, in a manner to bring the longitudinal axis of tliespindle 27 at an acute angle with said radial line, as shown by dot and dash lines in Fig. 2, so that when the extension member 22 is rotated counter-clockwise (Fig. 2) or to the left said axis of the spindle will incline in the direction of rotation.

Threaded in the car 29 on the extension member 22 is the adjusting thumb screw 30, having a collar on its stem below the threaded portion thereof adapted to compress a coil spring 31, the spring surroui'lding said stem below said collar and being anchored on the housing by means of stud 82, the end of the stem and said stud being separated by a space,\ whereby, when said adjusting screw is actuated a varying down.- Ward pressure may he brought to bear on the housing thereby rendering change ,for the purpose of avoiding the tab Z) Wi wheel is slanted upwardly from ogpcsite sides to form the apex 35, which is rounded and adapted to engage, when said wheel is rolled, the cam 35, arranged within the form 2, whereby the housing D'may be raised bodily from the upper edge of the form customarily is formed to extend beyond tne finished edge of the collar, such as 7;

(Fig. 6).

The collar (4 as indicated in the drawi is placed with its fold over the upper 11g of the form 2, the neckband thereof bei withm the form and the outer portion of the collar, overhanging the outer wall. in

order to hold the collar in proper relative position, relative to said cam 35 a flat spring 36 secured on the outer wall of the form 2 is provided.

As shown in Fig. 6 the outer portion of the collar is caused to abut against the stop E37 of the spring, the spring gently impinglng upon the collar to hold it in place. Thus, as the edging device is rotated the edging wheel will ride over the cam 35 and over the tab 5 of the collar, and then roll over the upper edge of the collar as shown, always under the influence of the pressure of the spring 31. In order to avoid undue shifting of collars of unusual shape and which may be projected outwardly to an unusual degree, a wiping flange 38 is provided on the housing, whereby anyv outward projecting collar portion may be engaged to push it inwardly without disturbing the position of the collar.

Fig. 7 represents a cross section of a collar illustrating for clarity in exaggerated form, the customary construction of a double fold collar showing the plies as they are assembled and stitched together. It will be noted upon inspection of the drawing, that the ply 0 forming the inner wall of the neck band, is doubledupon itself inwardly, adjacent the upper folded edge of the collar. This forms a ridge close to the finished edge of the collar, which in poorly laundried collars frequently stands out, forming sharp 1."ough edge as indicated in Fig. 8 at (Z. This is very annoying to the wearer, in that it cuts and abrades the shin.

Further when the heated iron is dragged v of the collar becomes polished. This is very objectionable where a dull finishis now required. In order to iron out any possible roughness at the point (Z without also polishing the top edge of the collar, applicant tilts his edging wheel inwardly so that the flange 34 clears the outer face of the collar, and to effect a wiping movementfrom below upward over the projection d, so as to wipe it into flush relationship with the outer ply 9 of the collar as shown in Figs. 9 and 10.

applicant disposes his edging wheel at an angle to a radial line cutting the center of the form 2, whereby the point of contact of the wheel with the collar is shifted behind the radial line relative to the direction of travel. Obviously, that half of the wheel forward of a vertical line cutting the axis of rotation is traveling leftward, counterclockwise and downward, and that other half of the wheel is traveling upward. The point of contact, as at a0 is within the upwardly moving half of the wheel as indicated in Fig. 2. Thus there is a frictional upward engagement between the wheel and collar, as the housing is rotated about the shaft 4, polishing and rounding the collar at (Z as indicated in Fig. 10, the frictional action changing to a rolling action before the top or visible portion of the collar is reached. It is to be remembered. that collars before being subjected to the edging process are moistened along the upper edge, which softens the fabric rendering it pliable so that the edge (Z may easily be pressed into flush relationship with the top part of the collar.
