To all whom it may concern:

Be it known that I, EMRY J. DUNKLEn,

v a citizen of the United States, and a resident of Hackensack, in the county of Ber.- gen and State of HenZJ ersey, have invented a new and Improved Cloth Renapping and Refinishing Machine, of which the following is a full, clear, and exact description.

This invention relates to a cloth finishing machine adapted to be used by tailors or renovators of garments, whereby those portions of a gannentwhich are shiny or have the'nap worn off can be re-napped, cut and pressed so as to have the appearance of a new fabric.

The general object of the invention is to provide a cloth or garment napping machine embodying a table on which the cloth or garment can be held in stretched condition for enabling the napper, cutter and presser to operate most effectively thereon, the table embodying a board or holder on which the article to be re-napped is laid,

and coacting spring-closed jaws for holding the article in smoother stretched condition.

A more specificobject of the invention is the provision of a table including novel means for closing the jaws by foot pressure and foot-operated releasing means whereby the jaws will spring open.

An additional object is the provision of a stand or table which forms a support. for

the motor by which the napper and cutter are operated, and also on the stand are switches for controlling the circuit for the cutter and na per and for varying the temperature of t e presser or ironer, and also on the table is arranged a shelf which forms a support for the various implements when not in use.

Additional objects of-the invention are to provide simple, novel and eflectivenapping and nap-cutting implements which are adapted to be connected one at a time with a motor through a flexible shaft.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth w1 th particularity in the following descrlptlon and claims appended hereto.

7 In the accompanying drawings, which illustrate certain embodiments of the inven-, tion and wherein similar characters of refclosed and the nap cutter in position for use;

Fig. 3 is a central vertical section taken longitudinally of themachine with the napper in position for use;

Fig. 4 is an enlarged transverse sectional new of the machine; 5 1s a diagrammatic view of the circu1t connections;

' Fig. 6 is a sectional view of the p'resser or lroner;

' Fig. 7 is a vertical section of the napper; Fig. 8 is a bottom plan view thereof; Fig. 9 is a bottom plan view of the cutter; and

Fig. 10 is a vertical transverse section thereof.

.The machine embodies a stand or table which is adapted to rest on the floor and carries the motor switches and implements necessary for the operation of the machine in performing'the three steps of napping jaws t cooperating with the board or holder,"

arms 5 for supporting the jaws, vertical slides or followers 6 for swinging the arms to open and close the jaws, a latch-member or foot presser bar 7 for moving the followers 6 downwardly, springs 8 for moving the followers 6 upwardly to open the jaws,

a releasing pedal 9 for releasing the foot latch member 7, and end frames B which support the cloth holder or board 3 onthe main frames A and shelf 1.

Each frame A embodies a pair of legs'lO, a bottom cross member 11, and a pair of in termediate horizontal cross members 12 between which latter the board forming the shelf 1 lies, with the .ends of the shelf extending beyond both frames A. The members 10 project upwardly above the shelf 1, and pivotally mounted therein are bear'-' ing members 13. Each bearing member 13 has an opening 14: therein through which the straight portion. 15 of a Jaw-carrying arm 5 slides. Each frame A has a centrally disposed member 16 provided with a vertical slot 17 and movable up and down in this slot are the ends of the latch bar 7, there being a notch 18 at the bottom of each slot 17 for permitting the latch bar 7 to be engaged therein for holding the jaws in closed position, as clearly shown in Fig. 4. The springs S are of the helical extension type and have their lower ends connected at 19 with the foot-actuated latch bar 7, and their upper ends are connected at 20 with the under side .of the shelf 1. The jaw-carrying arms 5 are arranged in pairs with an arm for one jaw opposite to the corresponding arm. of the other jaw, and the lower ends of the companion jaws are connected by a pivot 21 with the upper end of a slide or carrier 6, which latter moves through a vertical slot 22 in the shelf 1, as clearly shown in Fig. 3. The lower ends of the slides 6 are connected by links 23 with the ends of the foot-actu- At the rear of the mar ated latch bar 7. chine are cross bars 24 lying under the shelf 1 and extending from one frame A to the other, whereby the stand or table-is stiffened. Thefoot-actuated latch bar is released from the recesses 18 by upwardly extending arms 25 on the treadle bar 9 which has forwardly extending arms or members 26 by means of which'the operators foot can cause the treadle to be oscillated to swing the arms 25 into engagement with the latch bar 7 for re leasing the latter, this movement of the arms 25 being indicated by the full and dotted line positions shown in Fig. 4. When the latch bar 7 is thus released the springs 8 move theslides 6 upwardly so that the arms 5 and jaws 4 move from the full to the dotted-line position, Fig. 4. The releasing treadle is normally held out of engagement with the latch bar 7 by means of springs 27 which are connected with the arms 25 and with the cross bracing strips 24.

The cloth holder or board 3 is comparatively long and narrow so that it is possible to insert the same into a coat sleeve or trousers leg. The frames B which support the holder 3 are formed in any suitable manner, as, for instance, by metal strips 28 which have their lower ends fastened to the bottom bars 11 of the frames li and have their upper ends connected together by cross pieces 29, the intermediate portions of the metal-strips 28 being fastenedto the ends of the main shelf 1. Braces 30 are employed between the shelf 1 and the portions of the strips 28 between the shelf 1 and the cloth holding board 3. As shown in Figs. 1 and 3, the left end of the cloth holder 3 is connected by a hinge 31 with the left end frame B, and the other end of the board 3 simply rests on the right end frame B. By being mounted in this manner the cloth or garment-holding boar 3 can be raised as indicated by dotted lines Fig. 1, for permitting coat sleeves or trousers legs to be placed on the board. The jaws 4 are adapted to cooperate with the side faces of the board 3 and they are so positioned that when closed they lie below the top surface of the board so as not to interfere with the implementsto be used on the cloth for re-napping the same. The jaws are provided with pins or teeth 32 which pass through the cloth and enter the board 3 so as to keep the cloth stretched while being treated.

The removable shelf 2 is made in two sections on and b connected together by a hinge 33, and the outer ends of the sections are provided with notches or recesses 34 to engage the braces 30 or strips 28 to hold the shelf against lateral displacement, the said shelf resting on the upper ends of the frame A and lying between the pairs of opposite arms 5. On this shelf the napper, cutter and presser are adapted to be laid when not in use.

, The shelf 1 forms a support for the electric motor M and the switches 35 and 36 for the motor and the presser or 'ironer, respectively. The motor M has a flexible shaft 37 connected with the shaft of the armature, and attached to the rotatable element 38 of the flexible shaft 37 is a socket or chuck 39 for connection with the shaft of the napper or cutter.

In the diagram shown in Fig. 5 the motor M is connected with the wires 39 and 40 of the supply circuit, one side of the motor circuit including the two-point switch 35 for opening or closing the motor circuit and for closing and opening the presser or ironer circuit C. In the circuit of the presser C is the. switch 36 having means for connecting either one or both of the heating windings 41 and 42 in circuit to obtain a low, medium or high heat.

The presser or ironer C embodies oller 43', Fig. 6, which is journaledin a yoke 44 that has a handle 45. Within the roller and in close proximity to the metallic shell 46 thereof are the windings 41 and which heat the shell 46 to the desired temperature for pressing or ironing the cloth. The wires 47, 48 and 49 extend from the switch 36 to the presser or ironer C through the handle thereof.

The napper shown in Figs. 7 and comprises a casing D which has a flat bottom 50 formed with a rectangular opening 5 which extend parallel wires 52 so as to en-- gage the cloth and keep the same in proper condition for napping. In the casing is a roll 53 which has spirally wound on its circumference a leather or other strip 54 which carries a plurality of steel wire teeth of such length that the extremities of the teeth projecting downwardly pass out of the opening 51 just far enough to act on t .e cloth over which the napper-is passed, so as to raise a new nap. The teeth 55 are arranged close together and the roll or brush rotates at a high speed so that a uniform na can be produced by the passing of the evice over a worn surface of a piece of cloth. The shaft 56 of the nappingbrush has an extended end 57 shaped to interlock in the socket or chuck 39 of the flexible shaft of the casing engages.

After' the cloth is napped it is necessary to trim the fibers so that the nap will be of uniform length and to correspond with the nap of the cloth where it is not worn away. This trimming of the nap is done by the cutter shown in Figs. 9 and 10. This cutter E comprises a casing to which is rigidly fastened a yoke 60 having a handle 61, and in the casing is a rotary cutting element including a shaft 62, cruciform members 63 and helical cutting blades 64 having their cutting edges arranged at the same radial distance from the shaft 62. The shaft has an extension 65 at one end shaped to interlock in the socket 39 of the flexible shaft 37 of the motor. The casing has a serrated or toothed plate 66 which cotiperates with a cutter bar 67 to form a base which rides on the cloth as the cutter is in operation. The tips of the teeth or serrations 68 are slightly spaced from the sharp edge 69 of the cutter, and in this space the cutting blades 64 suc cessively operate on the nap to sever the same by the coaction of the blades 64 and cutting bar 67. The cutting bar 67 can be adjusted back and forth by means of setscrews 70 threaded inthe rigid base bar 71 of the casing, and clamping screws 72 pass through slots 73 in the cutting bar 67 and screw into the heads 74 of the casing, whereb the bar 67 is rigidly clamped in place. 'l he blades 64 are adjustable on the arms of the frames or carriers 63 by means of clamping screws 75 which pass through the ends of the blades and screw into the arms of the carriers or frames 63. The blades are adjustable radially by the use of set screws 76 threaded in the carrier 63 in such position 'that the inner edgm of the blades bear against the outer ends of the gage or set screws. In this manner the blades can be accurately positioned with respect to the cutter bar. After the cloth has been renapped and the nap cut to proper length the cloth is finished by passing the heated roller, presser or ironer C thereover.

posed of hin If desired, the flexible shaft 37 may be indirectly connected with the motor M through a speed-reducing transmission consisting of a pulley 80, Fig. 3, on the shaft 81 of the motor, a belt 82 passing around the pulley, anda pulley 83 driven by the belt and connected with the rotary element of the flexible shaft 37 through a universal coupling 84 of any approved construction, as shown in Fig. 4.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of-operation will be readily understood by those skilled in' the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.
