App1 ication filed February. 28, 1922. Serial No. 539,952.

To all whom it may concern: p 1 I Be it known that I, GEORGE J. Ax'r, a citizen of the United States, ,and a resident of Nutley, .in the county of Essex and State of New Jersey, have inventeda new and Improved Attachment for HGDIIBQIS, of which the following; is afull, clear, and exact description, 7 :o

This invention relates to an attachment for hemmers. whereby'the material which is being hemmed can be very readily fed to the hem securing mechanism.

An objectof the invention is to provide a very simple and readily applicableattachment for V hemmers whereby the, operator can very quickly and easily advance the material being hemmed to the hcni securing mechanism and without any danger of injury to the fingers.

Another Ob ect resides 111 the provision of a very simple meanswhich can be readily" applied to and detached from any type of hemming mechanism with no necessity for altering the machine to which it is attached;

A further object resides in the particular construction and arrangement of parts' which are hereinafter described and claimed and shown in the accompanying drawings.

The invention is illustrated in the drawings, of which Figure 1 is a plan view of the attachment applied to a hemmer.

Fig. 2 is aside elevation.

Fig. 3 is an end view from the indicated in Fig. 2.

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may plane 33 be adopted without departing from the spirit of the invention.

Hitherto in operating hemming mechanisms difiiculty has been encountered in feeding the material through the scroll or device which folds the material and presents it to the hem securing apparatus. The reason forthis diificulty has been, especially in the case of scrolls adapted to form fine hems, that the material would become stuck in the scroll. Operators heretofore have used their fingers or a sharp instrument such as a hat pin or scissors, and the engagement'of these articles with the material, especially if it is fine material, would cause an impairment of the fabric.

to a sliding block 4. slidable in a groove of channelbetween flanges 5 and 6 formed in any desired manner on the plate 7. This plate 7 is attached by any suitable means,

such as screws 8 and 9, to the-.scroll-supporting bar 10. The plate 3 is provided'with a finger-engaging head or portion 11 and a knob This head 11 and knob 12 may be connected in any desired manner to the bloclrt. A spring 13 connected at one end 'tothe block tand at the other end to a pin 141 mounted ona rearwardly extended portion 15 of the plate 7 tends to hold the finger 1 in a withdrawn, retracted position.

This plate 7 and its co-operating parts, including the finger 1, is adapted to be readily attached to the scroll-supporting bar 10 from which the usual scroll16 is supported. This scroll is provided on its upper face with a slot 17 and the material, as it is fed inthe usual manner through the scroll, can be engaged through this slot. Thefinger or. plate 1 is disposed normally over the slot 17, and when the finger of the operator moves the headll forward, the plate 3 and the finger 1, being preferably of spring metal, are advanced and slightly depressed so as to cause the teeth to come into engagement with the fabric. The engagement of the teeth 2 with the fabric will enable the fabric to be very easily and quickly ad' vanced through the scroll to a point where the fabric is engaged bythe hem-securing mechanism which is located just beyond the end of the scroll 16. When the screws 8 and 9 are removed the plate 7, the block 4, the

plate 3 and the finger 1 with their co-operatplate having a channel thereon, a sliding block mounted in the channel, a sprint plate connected to the clock, and a dependent finger on said spring plate, said linger adapted when operated to engage the material in the scroll to feed it.

2. An attachinent i or hennners having a scroll. With a slot therein and a Support for the scroll, which comprises a plate attached to the support having a channel therein, a block slidahlc in said channel, a spring); plate connected to the hloclg. a dependent finger connected to said spring plate, and teeth on the lov 2r edge of the hnp'cr, aid finger extending into the slot and said teeth the material in the scroll when operated to feed the material.

An attachment for hennners har nc a scroll. With a slot therein and a support fior the scroll, which comprises a p ate ached to the-support having; channel therein, a block slidahlc in said channel, a spring plate Connected to the block. dependent finger connected to said spring plate, teeth on thelower' edge of said finger, said finger extending into the slot and said teeth engaging the materialin the scroll when operated to feed the material, and a spring vconnected at one end to the block normally tending to hold the block and the finger in a retracted position, the other end of the spring being connected to the plate.

An attachment for hennners having a scroll with a slot therein and a suppoit for the scroll, which comprises a plate attached to the support having a channel therein, a block slidable in said channel, a springplate connected to the block, a dependent finger connected to said spring plate, teeth on the lower edge of the linger, said finger extending into the slot and said teeth engaging the material in the scroll when operated to feed the material, a spring con- 'nected at one end to the block and normally ending); to hold it and the finger in a retracted position, and a fingei engaging head portion connected to the block and sprii'ig; plate whereby they may be advanced by the finger of the operator, the other end of the spring being connected to the plate;
