This invention relates to improvements inmachines for producing fancy Work designsv on cloth the particular work for vwhich this.

machine is intendedbeing of that type-known machine proper partly broken out. 55

'5 as punch work or hooked embroidery.-

At present, as far as I am aware,the only way in which such work can be done-is by means of punch needles held in the hand. As is well known to those .who have used such needles, the'production of a design thereby is a very slowaand laborious task. Y r The principal object of my invention there fore is to provide as 'a complete operating unit, a hoop over which the cloth to be Worked on isstretched, and an electric or hand oper-. ated machine "mounted in direct connection with the hoop and arrangedso that the needle of the machine can be quickly and easily moved over the entire area of the, cloth in. any 1203 direction without any disass'ociation of the machine relative to the hoop being had. By

means of this machine any design may be, worked'onthe goods'much quicker than is at present'possible, and with whichthe only physical effort necessary is that usedin guid- 7 ing the needle over the goods. j

A further object of the invention is to'provide adjustable means for enabling the depth of'the stitch and consequently the thickness of the mat or nap of the design, to bereadily altered to suit; and also to enable the distance between stitches'to be also readily adjusted.

7 Another object is to provide means for en-.

3 abling the machine to he tilted upwardly to one side withoutv disassociatingthe same from the hoop andthe work, "so as to cleartheneedle and adjacent parts a considerable dis tance from the work 'and so facilitate re- $03 threading operations. r

Other features of advantage and novelty will be apparent from a perusal of the following specifications. 7 Q

These and other objects I accomplish by 45 means of such structure and relative arrange'-' ment of parts as will fully appear by a perusal v of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the 5o several views: V

V Fig. 1 is aside elevation of the complete apparatus partly broken out. Fig. 2'is atop plan view of the same. Fig. 3 is an elevation of one side of the,

Fig. 4 isa fragmentary elevation of the machinelooking at another side.

Fig. 5 is a'similar view of the machine looking at the side thereof opposite to that shown in Fig. 3. I 3 v Fig. 6'is a fragmentary elevation of the apparatus showing the machine in the position occupied when tilted for rethreading operations.

Referring now characters of reference on the drawings, the numeral l-denotes a clamp for engagement With a supporting'table 2, saidclamp being formed on the lower end'of a rigid vertical post 3. Turnable in the-upper end of the 77v postisa spindle 4, ball bearings 5 being secured to the top of the spindleis an arm 74 6 depending from and turnably mounted on the outer end of which is a' rigid frame. Ball bearings 7 are disposed between the 7 frame, and the arm to promote ease of turn- I ing, and arejmounted in a housing 7a secured 8'0':- to said arm 6. v The frame -consists ofian upper horizontal tubular member 8 formed atone end with a downwardly depending extention 8a, the distance from the axis of turning of the'fra'me andthe'arm to the extension being less than the distance from said axis to p the spindle, so thatthe extension is free to pass'ins'ide the spindle and post. Atthei bottom ojf'the extension near the tablethe frame is formedwith a horizontal arm 812;

' of the frame member 8 opposite to the extension 8a, said stem being provided with holes 12 set 45 or thereabouts apart,,which'hcles C U more particularly toj'the-olr 60 i I of near thebottom.

are adapted to alternately receive a stop pin 13 which is attached to one end of a control lever 14 mounted on the member 8. The stem is thus normally held against rotation from one or the other of the two possible positions to which it may be turned. A pin 15 fixed in the stem' rides in an arcuate slot formed in the member 8 to limit rotation of the stem and prevent longitudinal movement thereof. The stem while separate from the frame actually forms a portion of the same, as will be evident. 7

Secured" to the outer end of thestemfis 18 a vertical tubular housing 17in whichis turnably mounted a sleeve'18, ballbearings 19 between the housing and sleeve facilitating the rotation of the latter. slidable through but turning with the sleeve'is a post 20 on which, above the member 1?, is fixed a collar 21.. The post tends to drop of its own weight so that the collar rides on the race 19a of the upper ball bearing, and is raised from such position when desired by a cam lever 22 which is pivoted onto the collar and is adapted to ride on said racewhen turned to a vertical position; These pa'rts are so disposed that when said leveroccupies such vertical position the post is then raised approximately position.

becoming entangled with the operator or the work, the wires 25 from'the motor lead to cured to the housing 17 anddep'ending about the strips 26"so as to enclose the same throughout their extent. Wires 30 from the pins lead through or alongside the supporting-structure of the machine to a polnt near the spindle 4, as shown in Fig. 1, then forming an extension cord which leads thence for connection to a light or outlet socket.

Fixed to and depending from the post 20 is a block 31 in which is mounted a horizontal This shaft shaft 32 parallel to the motor 24. has a pulley 33 thereon which is driven from the motor pulley 34 by a belt 35.

arranged to detachably support a hollow needle 37 of a character suitable for this work, and having a hole 38 in one side there- At its upper end the bar 7 is attached to one end 'of a connecting rod 39, the other end of whichis pivoted onto a crank 40. This crank projects from and is radially adjustable in the shaft 32, so that the one half inch from its lowered- Secu'red to the post on one side of the same: below the housing is a'bracket 23 on which is mounted an electric motor 24 of thetype' commonly used for sewing machines.- To enable the current to be readily conveyed to the motor without the possibility ofthe wires.

Slidablet in the block is a needle supporting bar 36,

with this wheel is a ratchet wheel 43 (see Fig. which is engaged by a pawl 44 depending from a vertical stem 45 slidably mounted on the bracket 41.; At its upper end this stem is connected to one end of a lever 46 which is pivoted intermediate its ends onto the block 31 (see Fig. 3); the end of the lever opposite to its connection with said stem passing under the shaft 32 and being pressed thereagainst by a spring 47. Said lever end is positioned to be engaged, once with every revolution of the shaft 32 and when the needle is raised to the top of its stroke, by a radial adjustable pin or cam 48 mounted in the shaft 32. This engagement of said end of the lever causes the opposite end thereof to be raised, pulling up on the pawl 44 and causing the ratchet wheel and consequently the feed wheel to be rotated. The extent to which the lever is moved, and consequently the extent towhich the wheel will be rotated depends on the distance of the pin 48 from the shaft, as will be evident. Since the for ward'movement of the needle is governed by therotation of the wheel, it will be seen that the rate of feed, or the spacing of the needle between its projections through the cloth, maybe adjustedaccordin to requirements.

A bowl or cup 49to support a ball of thread is supported from the bracket 23 to one side of the block 41; the thread 50 passing from the ball through a hole in the side of the cup and thence through guide eyes 51 down through the needle from the top thereof and out through the bottom hole 38 therein as shown in Fig. 3. A presser foot F is disposed at about the same level as the bottom of the 7 feed wheel, and is located between the wheel and the needle just behind the latter relative to the direction of movement thereof. The ring 9 is disposed so as to be concentric with the needle and is of suflicient diameter to avoid contact with the wheel 42..

In order to support the cloth. to be worked on in proper relationship to the needle the post 3is provided with a socket 52 projecting radially therefrom. This socket receives a stem '53 projecting radially from a hoop structure which comprises a plurality of relatively slidable segments 54 connected together to form 'aunitary structure by bands 55. The segments are supported from thetable 2 by feet 56. The different segments are expanded or contracted so as to alter the diameter ofthe hoop by means of screws 5'? dis- Ill) posed inside the hoop area and threaded through lug-s 58 projecting inwardly of the segments near their adjacent ends. On the I outside of the hoop rubber or similar pads 59- the holding socket, the cloth 61 to be worked on is stretched over the hoop and bent down over the sides to engage the pads, and the band 60 is then applied over the cloth. The hoop screws 57 are then tightened up to stretch the hoop segments and placethe cloth under the necessary tension. The hoop is then connected to the socket 52 and work may be commenced. v

Owing to the numerous swivel connections between the machine and the fixed supporting post 3, it will be evident that the needle may be easily moved to any position on the cloth. When thus moving the machine to a starting position it is held raised by raising the post 20 by manipulation of the lever 22 so that the forward wheel and other parts are held clear of the cloth. When the needle is located at the starting point, said post 20 is lowered so that the feed wheel and presser foot firmly engage the cloth, depressing the'same inside the ring 9 owing to the weight of the machine parts, and as plainly shown in certain of the views of the drawings. The motor is then started up and it is only necessary for the operator to guide the machine along the outline of the design imprinted on the cloth, since the needle will be reciprocated and will feed forward of itself as long as the motor is in operation. When it is desired to cause the needle to travel in a reverse direction, it is only necessary to rotate the post 20 through a half turn without disturbing the hoopor cloth.

As is the case with work of this character done by hand the thread initially assumes the form of loops depending from the under side of the cloth, as shown in Fig. 3, the length of the loops and the spacing depending on the stroke allowed the needle and the extent of feed of the feed Wheelboth of which may be controlled at will as previously explained. To complete the work the loops are cut through by shears to present the desired matlike or thick nap surface after the cloth has been removed from the hoop. Since the clothtension ring 9 is mounted on the same frame on which the machine is mounted, any movement of the machine causes a like movementof the ring, so that the latter is always concentric with the needle and always follows up'the travel of the latter across the cloth. When it is desired to rethread the machine it is tilted to one side as'shown in Fig. 6 by release of thepin 13 and manual movement of the machine to the desired position, when the pin 18is again permittedto drop into the other one'of the holes 12 which will then be alined with said pin. This holds the machine in the tilted position as long as may be desired. This operation raises the needle some distance abovethe'work without disturbingithe latter, so that threading operations may be very quickly and easily accom- Plished. I
