EMBROIDERY-FRAME.

Application filed July 2-5,

To all 'w/mmit may concern:

lie it known that I. EVILLIAM KoLLnn, a citizen of the United States, residing at .lhite Plains, in the county of l l estchester and Eitutc of New York, have invented cer- '21 new and useful Irv n-cements in Embroidery rumes, 0; h the following is a full, cl ar, and exact specification.

This iITFQDtlOIl relates to embroider frames. and has for its object to provide improved means for accurately fixing each one of series ct similar patterns on as many pieces of cloth, each carried by a separate frame adapted to be nsced in turn below the needles i an embroidery machine, whereby all oi the pieces of cloth may be emln'oidered alike and so that the embroidery will accurately cover the desired design or pattern printed on each of said pieces of cloth.

The invention contemplates the provision of a plurality of cloth cl ping and holding frames, eecli comprising upper and lower frame members bet ween which the cloth is adapted to be clamped, a. table over which said frames are adapted to be successively moved on a track or gnideway, :lmorable member carrying design or pattern locating points adjustable thereon and adapted to he brought into register with the pattern or desi n on each of cloth monntec the cloth in each the pattern locating I i means for clamping said piece of cloth its fro -e after proper" adjustment accord said point to insure the proper location the design or pattern wits respect to freme when placed in the embroidery machine.

.ihe invention will be hereinafter decrioed n detail in connection with too 218- eying drawings, which constitute part i. i specifi ation, and then more spe ciinlly defined in the claims at the end of points. r

Each frame, as shown in Figs. 7 and 8, comprises upper and lower clamping parts of substantially the same shape, the lower cated at 12 in Fig. 6.

part 5 having side bars and

transverse bars

6 and 7, respectively, in the form of channels 10 communicating with one another, Fig. 7 and the upper part 50 having corresponding side bars 8 and transverse bars 9 having continuous ribs 11 to fit in said channels 10 of the lower part for clampinga piece of cloth to be embroidered, as indi- In order to insure a tight gripping action on the cloth between said rib and channel, the upper part carrying the rib may be covered with a layer of rubber 13, Fig. 11, or other suitable material which will also prevent injury to the cloth. a

As shown in Figs. 1 and 2, the lower part or clamping member 5 of each frame has downwardly oifset rearward extensions 14c to its side bars 6, said extensions being provided with upwardly extending arms 15 to the upper ends of which the upper clamping member 50 is hinged at 16 by extensions 17 of its side bars 8 which extend beyond the hinges 16 and have their extremities connected to the extremities of the extensions 14: of the lower clamping member by springs 18 which automatically raise the upper clamping member away from the lower member when released at their front ends as will be later explained.

In Figs. 3 and 1 a modified form of connection between the rear ends of the clampbrought together.

ing parts of the frame is shown in which the extensions of the-side bars of said parts do not extend beyond the hinge 19 and a bowed spring is interposed between said extensions in advance of the hinge of each pair of extensions, as best seen at 20 in Fig. 3. These bowed springs 20 have the same action as the springs 18 of the other form of the device just described, that is, they automatically raise the upper clamping member away from the lower clamping member of the frame when said members are released at their front ends.

The two clamping members of each frame may be latched together at their front ends by means of a hook-shaped latch 21 hinged at 22 to the front end of the upper clamping member 50 and adapted to have its lower hooked end take under the front end of the lower clamping member 5 as shown in Figs. 1, 3, 5 and 9. Said latch has an outstanding lug 23 against which a spring 2d carried by the upper clamping member bears for auto matically moving the latch into locking position when the members of the frame are The latch also carries a rigid pin or arm 25 extending substantially horizontally therefrom, when said latch is in vertical locking position, for operating the same as will be hereinafter explained.

At one point'on thetable a rearwardly extendingbracket 26 is secured and to said bracket the pattern positioning member 27 is hinged, said member extending forwardly 7 across the table above the frames 3 and adapted to rest on blocks for spacing it above the member 50. As shown in Figs. 1 and 2, the member 27 is hinged at 28 to an upstanding arm 29 on the bracket 26 through an intermediary horizontal link 30 which is in turn hinged at opposite ends to a downwardly extending stud 31 on the member 27 and a vertical link 32 which is also pivoted to the member 27 at 33 and to a treadle 34 at 35. The rear'extremities of the member 27 and bracket 26 are connected by a spring 36 which automatically raises the member 27 and holds it above the embroidery frames except when the treadle is pressed down, said treadle operating through the

links

32 and 30 to swing the member 27 clownward over said frame. Lateral swinging of the member 27 is prevented by a guide arm or bracket 37 on the rear end portion of said member engaging a slot 38 in a standard 39 attached to the bracket 26.

The hinge structure for the member 27 as shown in Figs. 3 and 4 is similar to that just described except that the rear end of the member 27 is curved downward at .40 and connected directly to the horizontal link 30, thus dispensing with the lug 31 of Fig. 1, and the spring 41 for raising said member is connected to said curved end of the latter at the point of hinge connection thereof with said link. In this form of the invention the guide arm or bracket 42 for preventing lateral swinging of the member 27 is connected to the bracket 26 and the slotted standard with which said arm engages is secured to the member 27 as shown at 43.

The member 27 has a slot 4 1 in the portion thereof disposed directly over the middle portion of the frame positioned below it on the tracks of. the table, and in said slot there are adjustably secured 'a plurality of pattern positioning points or devices 15. As best shown in Fig. 10, two of these positioning points are preferably carried by each of a plurality of clamping bolts 16 fitted to slide in the slot 44 and adapted to be clamped in adjusted positions therein by a nut 17 on the lower end of each bolt cooperating with a thumbhead 4-:8 on the upper end of said sign or pattern tobe embroidered on the cloth mounted on the frames, which design or pattern is marked on the cloth before the same is placed on the frames as already eX- plained. 5

The front end of the member 27 extends forwar ly beyondthe frame 3 a d said. ex-

around the bolts and be slot 53 a bolt 54 tending portion has a slot 52' therein through which t e end of the pin or arm 25 for oper ating the latch for the frames may extend, as best shown in Fig. 5. Another slot is formed in said front end of the member 27 in advance of the slot- 52, and through said extends for connecting a slide 55 thereto. Said slide has an upstand ing finger piece 56 at its front end for moving it forward, and to its rear end a spring 57 is attached for automatically moving the slide rearward when the finger is removed from said finger piece. The rear position of said slide may be determined by a block 58 secured to the member 27 and by the bolt 54. engaging the rear end of the slot The slide 55 has a slot 59 therein adapted to register with the slot 52 in the member 27 when the slide is moved forward but which does not fully aiine with said slot 52 in normal msition of the slide as shown in solid lines in Fig. 5, the end of the arm 25 extending beyondihe front. end of said slot 59 in such normal position of the slide.

in the operation of the invention the frames 3, having the cloth 12 mounted thereon with the design or pattern 60, F 2, top frame, adjusted thereon as best centered according to the eye of the operator, are advanced along the track on the table to come successively below the positioning points 45 carriedby the member 27. As each frame is brought to a position below the member 27, as the middle frame in Fig. 2, the latch there of is released by raising the arm 25, whereupon the upper meml er of said frame will be ralsed away from the lower member thereof by the spring at the rear end of the frame, as already explained, leaving the cloth 12 free for accurate adjustment to register the design or pattern 60 with the points &5. During this adjustment of the cloth in the frame, the member 27 is supported above the upper member of the frame by the sprin at the rear end of said member 27 already described. After the adjustment has been made, the member 27 is moved downward by pressing upon the treadle 34. As the member 27 descends, the arm 25 on the latch 21 is engaged with the slide 55, as indicated in dotted lines in Fig. 5 and in solid lines in Fig. 9. Said latch is thus held in retracted position until the upper member 50 of the embroidery frame is engaged with the lower member 5 t iereof. Before the foot of the operator is removed from the treadle, the slide is moved by the finger piece 56 and against the tension of the spring 57 to release the arm 25, whereupon the spring 24; throws said rm to the horizontal position shown in solid lines in Figs. 1, 3 and 5, and engages the latch 21 with the lower member 5 of the embroidery frame, thereby locking the upper member 50 thereto.

It will be observed that by the means herein shown and described a great number of frames may be quickly and accurately adjusted so as to insure the proper stitching or cmbroidering of the patterns alike. Heretofore it has been necessary to adjust the cloth with the patterns centered merely by the eye, which was not accurate, or with a rule which consumed considerable time. It will also be noted that the number of the positioning points may be varied to suit requirements, so that any design or pattern, no matter how simple or complicated, may be adjusted by the present device both accurately and quickly.

it should be noted that in addition to the guides 37 and'39 at the rear end of the member 2'7, the front end of said member may carry a. transverse bar 61, Figs. 2, and 9, with turned down end portions 62 to fit between upstanding lugs (38 on the front end of the upper member 50 of each frame. Said lugs 63 are preferably beveled on their inner faces, as at 64, for guiding the end portions 62 of the bar 61 on the member 27 into proper position between them. This centering device also insures the proper positioning of the frames below the member 27, so that the positioning of the pattern in each frame will correspond exactly with the positioning of the pattern in the other frames.

As indicated in Fig. 1 at 65, if the piece of cloth to be embroidered is of considerable length, as may sometimes happen, especially where several designs are to be successively embroidered on the same piece, the extra length of the cloth which is not clamped in the frame may be rolled up and supported between the

extensions

14 and 17 of the side bars of the frame where it is out of the way and maintained in good condition during the adjustment of the design or pattern.
