Specification of Letters Patent.

tember 8, 1920. Serial No. 408,991.

To all whom it may concern:

Be it known that I, HARRY BENSON CRANAGE, residin at 20 Vicarage avenue, Kirkstall Lane, Kirkstall, Leeds, in the county of York, England, engineer, have invented new and useful Improvements in the Feeding Motion for Pressing and Other Machines, of which the following is a specification.

This invention relates to improvements in a feeding motion which is particularly applicable to ironing machines employed for pressing the seams of garments in which the seam is first opened and afterward pressed, but it may also be used on, or combined with, other machines where an intermittent underfeed is required. The apparatus was originally included in application for Patent No. 1,356,044, granted October 19, 1920, of which the present case is a division.

In the patent referred to are described and illustrated machines having a top feed and in which the feeding and pressing mechanisms are both separately and directly actuated by cams and levers directly from the driving shaft of the machine.

The object of the present invention is to provide an under-feed which is arranged to operate within the work support and to be separately and independently actuated from the driving shaft of the machine by means of shafts and gearing.

In the drawings hereunto annexed the in vention is shown applied to an ironing machine for pressing the seams of garments,- but it may, as stated above, be also em ployed upon other machines,in which Figure l is an elevation of a machine with vertical framework with the under feeding device arranged within the work support and actuated by means of vertical and horizontal shafts connected together by gearing;

Like parts in all the views are marked with similar letters of reference.

a is the standard of the machine which forms part of, or is fixed to, a square or other shaped base plate 6. The standard a is made of any suitable size and shape and it is provided with two vertical arms a a which project in an upward direction from the stem portion a and a suitable'space a is provided between the two arms for the reception of the work to be operated upon. The arms are made of different lengths, that is to say, arm a is shorter in length than the rear arm of. The upper portion of the arm a is arranged to form a vertical circular bearing for the reception of a spindle 0 upon which the hollow work support 6 is mounted. The work support 6 may be of any suitable and desired shape, as, for example, rectangular, as shown in the drawings.

At a suitable distance from the top of the vertical bearing on one or opposite sides is or are provided a slot hole or slot holes 7 of any suitable length to permit of a limited vertical movement of the work support. Through the slot holes 7 and spindle 0 is passed a pin or projection g which prevents the spindle from turning in its bearing. The vertical hole in the bearing is made of such a length as to permit of a coiled spring it being inserted therein. Below the bottom of thespindle c and in the lower portion of the bearing is formed a second vertical hole 2' through which the lower reduced portion 03 of the spindle 0 is made to pass, and the spindle is connected to a treadle for raising and lowering the work support e as will be presently described.

The rear arm a of the framework is bifurcated at its top a for receiving the operative mechanism consisting of a driving shaft 3', fast and loose pulleys 7c, Z'mounted thereon and a cam m arranged to operate upon a roll a carried in the bifurcated end of an adjusting spindle 0 and retained in position by a spring 79 arranged to work in the rear end of a double ended lever g pivoted at r to the bifurcations a of arm a The front portion 9 of the double ended lever has jointed thereto a pressing iron s'by lugs 26 and pin or spindle u. The pressing iron is made hollow and may be heated by as, electricity, steam or oil. In the drawihgs it is shown asbeing heated by gas which is conveyed thereto from any suitable source of supply through pipes '0.

The machine is provided with belt shipping apparatus comprising a fork w fixed to lever 00 mounted upon the pin or spindle g in the brackets, and connected by a rod 1 to lever 52 mounted upon shaft or spindle 3 upon which is also mounted a treadle 4 for operative purposes.

The rear end of lever q is retained with its end in contact with cam m by means of spring 5.

Most of the herein described parts,with the exception of the work support and feeding device,are of a similar construction to those described in the aforesaid Patent No. 1,356,0-1 1. In this arrangement the feed is below the work and inclosed within the work support a, and the requisite motion is imparted to the feeding device by means of two vertical and one horizontal shafts and gearing. The feeding device is arranged on similar lines to that of the feeding foot of a sewing machine and it is arranged to work within the hollow work support 6. The up er surface 6 of the work support is provic ed with a rectangular opening 6 in which the upper surface of the feeding device 7 is arranged to reciprocate. The feeding device is provided with two rows of serrations 8, but the number of these rows may be increased or diminished as circumstances re quire. Two of the sides of the said feeding device are provided with headed or other projecting studs 9 which are screwed therein and upon which are mounted dies or blocks 10 arranged to work in inclined slots 11, 11, shown at Figs. 1 and 3. The inclined slots are formed in two opposite sides of the work support 6. In the undersurface of the feeding device 7 is formed a recess 12 in which is arranged to work a cam 13 having a flange 14 on its lower edge. The cam 13 i keyed or otherwise fixed upon the upper end of the vertical shaft 15 which is carried in bearings formed respectively in the spindle c and in the boss Mi -which is Inountet in a bearing 17 formed for its reception in the arm a of the standard 0J,- of the miter wheel 18 which gears with a wheel 19 mounted upon the horizontal shaft 20 and having a gear wheel 21 meshing with wheel22 carried in a bearing or bracket 23 fixed to the standard a. Wheel 22 is fixed upon vertical shaft 24, the upper end of which is carried by a bearing formed for its reception in a bracket 25 and upon the end of the said shaft is mounted a gear wheel 26 arranged to mesh with a wheel 27 mounted upon the driving shaft j. The boss 16 is provided with a ring- 28 so as to permit of it rotating "freely within the bearing 17 in which it is mounted and'the shaft is provided with a spline or key so as to permit of it rotating withthe gear wheel 18 and at the same time to permit of the work support 0 and spindle 0 being raised or lowered. by treadle 4: as and when required. The treadle a is connected by a rod 29 to a plate 30 fixed at a suitable distance from the lower end of the reduced portion (Z of the spindle 0.

A work table 31 is fixedto the web a, of the standard a for preventing the work operated upon falling upon the floor and becoming soiled.

The action of the machine is as follows The iron 8 having been raised and the work having been placed on the upper surface e of the work support 6 and the iron having been heated to the required temperature the belt is thrown by the shipping fork w 011 to the fast pulley is by which motion is imparted to the driving shaft j, cam m, arm 9 for operating the lever and bringing the iron 8 into contact with the work upon the support 0. At the same time motion will be transmitted from the driving shaft j through gearing 26, 27, shaft 2 1-, gearing 21 and 22 to the shaft 20 which is arranged at-an angle,-as shown at Fig. 2,-gearing 18 and 19, shaft 15 to the cocentric 13 which thereby imparts the requisite reciprocating motion to the feeding device 7 and by means of the dies or blocks 10, 10 being attached to the side of the feeding device and mounted in the inclined slots 11, 11 a risin and falling motion is imparted to the feeding device as well as a reciprocating motion for feeding the seam or garment operated upon.

The seam of the garment is opened by the nose of the heated pressing iron 8 during the feeding of the apparatus along the top 6 of the work support,- as shown at Fig. 1,-in the direction from left hand to right hand. After the heated pressing iron has descended on to the open seam for pressing purposes, and a portion of the seam has been pressed, the pressure is slightly relieved by cam m permitting the spring 5 to raise the iron 3 a little to permit of the serrations 8 of the feeding device,-the serrations 8 will then have been raised by the movement of the dies or blocks 10 in the inclined slots 11 so as to project above the level or top e of the work support c,being moved by the eccentric 13 acting against the right hand inner wall of the recess 12 in the feeding device 7,-that is, toward the driving shaft j,-for feeding the seam against the nose of the heated iron. By retaining the seam against the flatundersurface of the heated iron .9 during the feeding movement the seam is opened by the nose of the iron; when the iron 8: again descends another portion of the seam will be pressed. During thepressing operation the feeding device 7 descends within the recess or cavity 6 in the work support e this descent being caused by the downward movement of the dies or blocks 10 in iaoneee the inclined slots 11, and it is also moved in an outward direction,to the left,-and raised again into a feeding position. This cycle of operation is continued until the seam has been pressed.

What I claim is 1. In a machine for the purpose described, the combination with a work support, a pressing member adapted to cooperate therewith, and means for positively moving the pressing member relative to the support, of a feed plate carried by the support, connections between the means for actuating the pressing member and said plate for reciprocating the latter, and means for automatically moving the feed plate relative to the work support and toward and from the pressing member as it reciprocates.
