"Sleeve presses are usually providedwith two upstanding or vertical forms vI and 2 mountable upon carrier means asa carriage 3 which ha'sra rearward and forward movement to carry the forms l,2,into and out of" position between pairs of cooperating pressing elements located. in

spaced upright housings 5,. 6', 1, supportediby the machine frame, members of each pair'being'located' within the housing 6, and th'e opposin'g members of the "pairs being located in sidehousi'ngs 5, 1. There is a clamp mechanism for each form and these are rights and lefts. The clamp mechanism for the form I, at the left of Figure-3, is the left clamp mechanism. Theright and left mechanisms are practically the same in construction. It is apparent that a sleeve pressing machine may have but one sleeve-form and companion clamp mechanism, in which case" the sleeves of a shirt would be successively pressed on the one form. Each clamp mechanism includes a support II, a clamp carriage l2 movable along the support in a substantially horizontal path at the height of .the upper end portions of theform l or 2 about which the cuff C of the sleeve S is wrapped when the sleeve is dressed or sleeved on the form, the carriage l2 being movable outwardly to bring the clamp carried thereby into juxtaposition to grip the wit and being movable" with the form inwardly as the form is shifted into a position between the pressing elements, means operating to close the clamp as it comes into clamping relation to the form at the end of the outward movement of the carriage l2, Figures 1, 2 and 5, and to release the clamp at the end of the inward movement of the clamp carriage l2, Figure 2. Said means specifically comprises a motor for actuating the movable jaw of the clamp to cause it to grip the cuff, a member for'controlling the energizing and deenergizing of the motor, and a connection between the carriage l2 and the control member for operating the control member to energize the motor when the carriage l2 has been moved outward to bring the open clamp in juxtaposition to the upper end of the form, and release means operated by the return of the clamp carriage I2 inwardly to its normal position at the end of the inward movement of the form between the pressing elements to operate the control member to deenergize the motor and permit the clamp to be open during the pressing operation.

The support I I is here shown as a channel or a frame member formed with a slot l3 providing tracks along which run rollers I4 on the clamp carriage I2. The clamp carriage I2 is provided with the fixed jaw I5 of the clamp, and with a movable jaw I8 pivoted at H to the fixed jaw.

The power used for operating the clamp is preferably air and hence the motor is an air motor. The motor here shown is of the diaphragm type and includes a diaphragm I8 located in a chamber I3 acting on a sliding stem 20 which thrusts against a spring returned lever 2I pivoted at 22 at one end to a lug 23 on the diaphragm chamber and pivoted at its other end to an arm 24 on the movable jaw I6, the stem 20 thrusting against the lever 2I between the ends of the lever. Air is supplied to the pressure side of the diaphragm through a flexible pipe 25 connected to the diaphragm chamber on the pressure side of the diaphragm and to the casing 26 of a control member or two-way valve which is connected to a suitable source of air supply through an intake pipe 21. This valve is of the normally closed combined intake and exhaust type and as here shown the movable valve member includes an intake head 28 normally pressed against its seat by a spring 29, a normally open exhaust valve head 30 and a stem 3| connecting the heads. The valve isopened against the spring 29 by a connection between the clamp carriage I2 and :the movable valve member, this connection being shown as a link 32 connected at 33 at one, or its rear, end to a lever 34 which is pivoted at 35 to the casing of a diaphragm chamber 35, to be described, the link having a shoulder 31 at its other, or front, end arranged in the path of a coacting shoulder 38 on the carriage I2 and located to engage the shoulder 31 when the carriage I2 is pulled out manually by means of its handle 39 and approaches the limit of its outward movement wherein the open jaws are in juxtaposition to the cuiT wrapped around the upper end of the form.

The valve operating lever 34 carries a suitable spring pressed buffer plunger head H which thrusts against the stem 42 of the exhaust valve head 30. When the clamp carriage I2 is pulled outwardly to the limit of its outward movement, the shoulder 38 on the carriage I2 encounters the shoulder 31 on the link 32 and thus operates the movable valve member of the control valve to close the exhaust valve head 30 and open .the intake valve head 28, permitting air to flow from the intake pipe 21 through the flexible pipe 25 to the pressure side of the diaphragm chamber I9, thus closing the movable jaw I6 against the action of the returning spring 43. The valve is locked in its operated position by a diaphragm 44 in the diaphragm chamber 36 and connected to the interior of the control valvecasing 26 by an air duct 45. The diaphragm. 44 acts on a sliding stem 45 coacting with the lever 34 through an adjusting screw 41. Thus, when the control valve is operated to open its intake head 28 and close its exhaust head 30, air at the same time leaks through the duct 45 to the pressure side of the diaphragm chamber 36, actuating the diaphragm 44 to press the stem 46 against the set screw 41 and thus lock the intake and exhaust valve heads 28 and 30 in their operated position.

There is a connection for releasing the locking of the valve by exhausting the air from the pressure side of the diaphragm chamber 36, this being operated when the carriage I2 reaches the limit of its inward movement by reason of being clamped to the form, and the form being moved into position between the pressing elements. As shown, a release valve 50 is provided which is connected by a pipe 5| to exhaust the air from the pressure side of the diaphragm chamber 36 faster than the air leaks into the diaphragm through the duct 45. The release valve may be operated by a manual 52, Figures 1 and 7. It is normally operated however-automatically by a cam, as 53, Figures 1 and 6, movable with one of the carriages 3, I2, as the clamp carriage I2, the cam 53 coacting with a latch lever 54 which normally holds the exhaust or release valve head 55 closed, the cam 53 acting to move the latch lever 54 about its pivot 56 to unlatch the lever 54 and cause the lever 54 to press against the stem of the exhaust valve 55 and open it against a spring 51. The cam 53 on the carriage I2 is located to release the latch lever 54 as the forms approach the limit of their inward movement between the pressing elements.

It is desirable to release the clamps from the cuffs during the pressing operation to prevent pulling strains on the cuffs during the pressing operation. The manual 52 for this exhaust valve is connected to the latch lever 54 to operate it manually.

In operation,- after the sleeves are dressed or sleeved on the forms I, 2, with the cuffs atthe upper ends of the forms, the operator brings together the edges of the cuffs one by one and pulls out the corresponding clamp carriage I2 for the cuff clamp by means of the handle 39, this operation being performed on each cuff separately. When both handles are pulled out and both cuffs clamped, the operator, through a suitable control mechanism, energizes shift mechanism which moves the carrier means 3 for the forms into position between the pressing elements. The cufi clamps being clamped to the. cuffs thus move rearwardly and when they approach their rearward position, operate the release valves to open the cuff clamps.

This cuff clamp mechanism is particularly useful with forms I, 2, embodying an expander to adjust the forms to sleeves of various widths, or to stretch the sleeves widthwise before the forms are shifted between the pressing elements. The forms are usually of flat elliptical shape in cross section, and the expander extends from within the form through one edge of the elliptical formation. As the expander expands the sleeve, the cuff clamp is clamped on the cuff so that the sleeve adjacent the cuff is held from distortion and wrinkling during the widthwise tightening of the sleeve, and also the liability of straining and distorting the sleeve along the slash extending from the ends of the cuff and into the sleeve. or straining the gusset at the inner end of the slash, is avoided.

60, Figure 1, designates the expander in each sleeve, this being here shown as being pivoted at BI between its upper and lower ends to an upright spring arm 62 of an angle lever pivoted at its angle, the other arm 64 of the angle lever extending forwardly and having a handle 65 at its front end. The spring arm 62 extends into and lengthwise of the hollow form from the lower end thereof and has a follow-up action on the expander. The expander per se forms no part of this invention. It is however usually operated automatically by the machine power system as the form is shifting from its outer position to between the pressing elements. The cuff clamp remains closed on the cuff until the form reaches pressing position between the pressing elements. Hence, the cuff clamp is closed on the cuff before the expander is operated. The cuff clamp is released when the form reaches pressing position between the pressing elements.
