To all whom it may concern:

Be it known that I, DANIEL M. COOPER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Pressing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the referencenumerals marked thereon.

The present invention relates to pressing machines of the type in which a pair of members are movable relatively one toward and from the other for the purpose of pressing material between them, and an object of provide a construction by which a very great pressure may be obtained without the use of motive power.

Another object of the invention is to provide a pressure applying mechanism which is durable in use, simple in operation and inexpensive to manufacture.

'Still another object is to improve that type of pressing machine in which a work support is mounted to move into and out of vertical alinement with the pressing head, a novel means being provided for stopping the work supportwhen it is alined with the head, and novel means being also employed for releasing the work support after the pressing operation.

To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the .claims at the end of the specification.

In the drawings: Figure 1 is a front. elevation of the machine constructed in accord-- ance with this invention, parts being broken away, and other parts being illpstrated in section; Fig. 2 is an end elevation with parts broken away and parts in section; Fig. 3 is a section on the line a-aof Fi 2; Fig. 4 is a vertical sect-ion of the base'o the machine showing the mechanism for effecting the relative movement betweenv the work support and the presser head, and Fig. 5 is a detail view of the locking device which holds the work support in vertical alinement with the presser head.

The invention is, in this instance. em-

bodied in a-pressing machine for pressing or ironing wash goods, such for instance as shirt bosoms or other similar flat work, but it will be understood that the improvements are capable of being embodied in. any press ing machine operating upon a similar principle.

The present embodiment comprises a 1101- low base 1 having integral arms 2 extended outwardly from its upper end and supporting upright rods 3 whose upper ends carry a frame 4 having arranged on its under side a presser head 5 which in this instance is heated by any suitable means.

Mounted to turn'upon one of the upright members 3 is a supporting member having one or more supporting arms 6 near the outer end of each of which is provided a vertical hearing or guide 7. In this guide works a depending portion 8 on the work support 9 which in this instance is padded as at 10. The work support is prevented from turning in the guide 7 by a parallel guide member 11 working in the guide sleeve 12 on the arm 6, a spring 13, if desirable, acting between the work support and its supporting arm 6 to prevent any binding action in the guide 7, due to an unequal distribution of weight on the work support. The pressure applying mechanism or mechanism for effecting the relative movement between the work support and the presser head comprises preferably a toggle consistwithin the hollow pedestal or base 1. The upper toggle member'14 of this toggle is pivoted at lfi preferably to the swinging member 17 that is pivoted at 18 at one side of the longitudinal axis of the toggle and cooperates with that portion 8 of the work support depending through the bearing 7.

By connecting the upper end of the toggle to the swinging member greater strength and life for the machine is obtained and the cost of a great deal of machine work eliminated. The pivoted member 17 may have guided thereon an adjustable wedge piece 19 which increases the effective length ,of the toggle and is adjusted by any suitable means, as by the screw 20 turning in the wedge piece and engaging threads in the pivoted member.

The toga'le is straightened by any suitable ing of

link members

14 and 15 arranged means but it is preferred to employ a manually operable lever 21 pivoted to the frame of the machine at 22 independently of the toggle and having a link 23 pivoted thereto and to the joint 24 of the toggle. It is apparent that when this lever is moved in one direction it will straighten the toggle and cause the pivoted member to swing upwardly and force the work support toward the presser head 5. Of'course, on the movement of the lever in the other direction the joint of the toggle will be broken and the work support will lower under its own weight. The lever 21 is held in both positions by a dog 47 slidably arranged on the lever, controlled by a hand piece 47 a and adapted to enter

notches

48 and 49 on a j gle joint. 25

rack or segment 50. This segment also carries a stop 51 to limit the outward movement of the lever 21 and toggle. The inward movement of the toggle is limited by

cooperating stops

52 and 53 formed on the

members

14 and 15 in proximity to the tog- ,Ironiug machines of the press type are usually controlled or operated by girls, and the latter have not sufficient strengt to effeet a proper pressing of the goods with a single toggle. In this invention in order to obtain greater pressure, there has been combined with a toggle, a swinging member 25 pivotally supported at its lower end, as at 26, and having its upper end .pivotally connected as at 27 with the lower end of the lower toggle member 15 so as to form a toggle with said lower toggle member. This toggle preferably breaks in a direction opposite to that of the toggle formed by the

members

14 and 15 so that each toggle may operate without affecting the other. It is preferred to make the lower link or member 25 of less length than either the member 14 or the member 15 so that greater power may be obtained from the lower togglc. The latter is straightened preferably by an arm 28 rigid with the lower end of the member 25, being extended forwardly than the rock shaft 26 that forms the pivot of the member 25 and provided with a trundle 29 at its outer end. Stops 54 and 5.1 formed on the members 15 and 25 may limit the inward movement of the lower toggle and an arm 30 may be extended from the rock shaft 26 rearwardly to cooperate with the yielding stop 31 on'the frame inorder to limit the outward movement of said lower toggle. The shaft 26 may also have a weighted arm 100 extended rearwardly therefrom to counterbalance the treadle lever.

'lo effect the breaking of the toggle joint 27 the base 1 has pivotally mounted thereon at. 3; a lever treadle 33 whose rear end 34 cooperates with the arm 28 in advance of the rock shaft 30 so that when the forward end of the treadle 33 is depressed the latter will cooperate with arm 28 at its rearward end to elevate the said arm 28 and throw the upper end of the member 25 to the rear, thus breaking the lower toggle.

It is desirable to lock the work supportin vertical alinement with the presser 5 during the movement of the work support toward the presser and to this end a locking plunger 35 may be guided on the pedestal or base frame 1 and is pressed upwardly by a helical spring 36. Its upper end 37 is adapted to enter a notch 38 in the arm 6 and in order to guide the locking plunger to the notch an inclined surface 39 is provided On the arm and leads to the notch on one side thereof, while on the opposite side of the notch is arranged a stop 40 which contacts with the end of the plunger and prevents the arm 6 from passing the plunger when the latter is projected. Of course, the plunger ma be drawn out of the notch 38 and passed beneath the stop 40 and to this end the lower end of the plunger 35 .is engaged by an arm 41 on the rock shaft 42 which also carries an arm 43 connected by a link 44 with the rear end 34 of the treadle 33, lost motion being permitted betweenthe treadle and the link 44 by means of a slot 45 in the link receiving apin 46 on the treadle. lVith this arrangement, the lever of the treadle 33 may be depressed to break the lower toggle without affecting the locking device forthe work support, but

a further movement of the treadle may be employed for operating the locking device and thus an additional controlling device for the locking device is not necessary.

In operation, the work is placed upon the work support 9 preferably while the latter is out of alinement with the presser 5. The work support isthen moved into vertical alinement with the presser and is automatically stopped and locked in this position by v the spring-pressed locking plunger 35. Theoperative now moves the lever 21 toward the machine and the movement straightens the toggle formed by the

members

14 and 15 and causes the work to be placed under an initial pressure. A pressure now placed upon the treadle lever 28 will straighten the toggle formed by the members 15 and 25 and give a very great pressure upon the work. After the work has been subjected to the desired pressure, the treadle 33 is slightly depressed to break the joint 27 and the lever 21 then moved in a direction away from the machine, thus breaking the joint 24. A further depression of the treadle 33 releases the work support and permits the latter to be shifted transversely of its line of movement toward the presser 5.

A machine constructed in accordance with little effort or energy being exerted by the operative. The movement to and from pressing position is quickly obtained and the parts for accomplishing it are few and not 5 liable to breakage. The positioning of the work support in vertical alinement with the presser Sis automatically effected and thelocking thereof is also obtained by an automatic operation. The locking device is controlled by a member which also controls another part of the machine, thus making unnecessary the provision of an additional controlling element, and the release of the work support by the locking device cannot be effected except upon the reduction of pressure upon the work.
