This invention relates to pressing machines particularly machines for pressing articles as shirts, especially where it is necessary when ironing the front of the shirt or other work to stretch the same and hold it in its stretched position by pulling and holding the tail of the shirt. t

The invention has for its object a particu-' larly simple and efiicient work or tail holder to clamp the shirt tail in stretched position and hold it until the ironing head closes down on the shirt.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth'and claimed.

In'describing this invention reference is had to the accompanyingdrawings and to the combinations and constructions hereinafter set forth and claimed.

Figure 1 is a side elevation of a tail holder embodying my invention showing the same applied to one form of standard pressing machine.

Figure 2 is an elevation of this tail holder carrier including a flexible member as a tape which is carried by such movement into and out of position overthe face of the buck of the machine, the carrier also preferably having a vertical movement when the tape is over the buck, and means for effecting the vertical movement of the carrier to carry the tape toward the buck when the tape is in operative position and to .move the tape away from the buck during the initial part of the opening movement of the carrier or tail holder. The

vertical movement is such that the tape moves. away from the tail of the shirt and also applies itself to the tail of the shirtso as not 1 designates the lower pressing element or ried'at the front end of a yoke or lever 6 pivoted-at 7 between its ends to an upright.

8, risingfrom the frame or the rear leg thereof. The lever 6 is actuated through any suitable means here shown as a toggle including links 9, 10,-the link 9 being pivoted at 11 to the rear arm of the yoke 6 and the link 10 being pivoted in any suitable manner to the 'frame and actuated in any well known man- The actuation of the head 2 forms no ner. part of this invention and is so faras this 'tail holding means is concerned the head may be operated in any manner, either by the operator or by motor means. .The tail holder comprises a carrier which is here shown as pivotally connected to the frameto swing into and out of operative po s move vertically, and a flexible member as a metal tape arranged to be moved into and I out of position across the face of the buck.

The carrier as here shown ismounted to swing forwardly and .rearwardly and comprises front and rear carrier- frame arms 16 and 17 pivoted at 18 in a bearing 19 at one ition and also to end of a compound-motion support to be presently described. The bearing 19 may be 10-. cated below the buck and the arms 16 and I 17 diverge upwardly from its axis, the rear arm being arranged in the rear of the buck and the front arm having a vertical portion arranged to clear the end of the buck, and

a horizontal portion 20 movable over the face of the' buck during a forward'and rearward movement of the carrier. 21 is the flex ible member or metal tape connected at its at its rear end to the arm 17.

The support for the carrier is here shown as an arm 22-pivoted at one end at 23 to the frame and carrying the bearing 19 atits other end, the lever being movable downwardly against the action of a returning spring 24. The arm 22 carrie the c mpound-motion bearing motion.

Means is provided for moving the carrier I vertically and also for swinging the tape 21 toward and from the buck or the work theretically down against the tension of the spring 24 and tolet thecarrier rise abruptly to carry the tape of! the work during-the initial part of therearwardly, swinging movement of the carrier frame 16-17. The cam 25 is also provided with a seat 27 arranged to receive the follower, whi h is a roller, when the car rier has comple its vertical movement toward the buck. The rearward movement of the carrier is limited by a stop 17 on the frame.

In 0 e'ration after the shirt has been placed on the uck and the tail pulled to stretch the shirt front on the buck, the carrier 16 is pulled forwardly by hand thus moving the tape 21 over thebuck and the work thereon,

the tape or band 21 being spaced apart from the work until thefollower 26 rides down the abrupt cam 25, such movement brin ing the tape 21 squarely down onto the wor on the buck without wrinkling the work. The press head 2is then brought down to press the work and then caused to rise to open the press. The operator then pushes rearwardlyon'the carrier, first causin it to rise vertically and carry the tape 21 o the work and then rearwardly out of the way. v

The example of construction shown is to disclose the principle of the invention wherein a clamp tape orband 21 is carried on a suitable frame 1617 which swings said tape back and forth over the end of the buck and up and downin'relation to the work. The pivot 18 may be placed atany convenient position on the frame {Jr-8 of the ironing press. In the position shown under the iron jaws 1 and 2, the carrier-frame 16--17 quickly swings the clamp tape 21'over the righthand end of the lower press j'aw 1, clearing and not wrinkling the shirt or *other work thereon smoothed out in ironing position by the operator, and then the tape or band 21 goes down on the work and buck to hold the work in smoothed stretched-out condition so the operator may remove his hands and bring the ironing head down on the work to iron or-press it. a

The radius arm 22 is merely one example of pivot means to attain the vertical action of the clamp band 21; and the illustrated embodiment of the invention portrays-a car rier frame 16-17 having its'upper ends .spacedapart' a"distance greater than the I9 capable of vertical and rotary width of the buck, so that the, band 21 may frame 1617 is so arran ed as to neverinterfere with the work on t e buck and merely swings the clamp band'into and out of workholding position. It is significant that the be longer than the width of the buck. The

press head to de- Other forms of construction to swing the clamp tape or band'21 to and from the work may be utilized without departing from the spirit'of the invention, and the device fills a need felt for a work holder, to improve and speed up the ironing operations.

What I claim is 1 a head movable-toward and from the buck, a work holder carried by the frame and including a pivoted carrier swingable forwardly and rearwardly and having spaced apart members, a tape connecting the members, the front member, being shaped to pass over the face of the buck and to clear the end of the buck when moved into and out of operative position, and means for automatically mov ing the carrier to move the tape toward and from,the buck.
