PRESSING APPARATUS.

Application filed. January 5, 1927. Serial No. 159,173.

The present invention relates to pressing machines, and particularly those of a wellknown character. The primary object is to provide novel mechanism, by which the pressing head can be elevated to a greater or less degree, as desired by the operator.

The preferred embodiment of the invention is illustrated in the accompanying drawing, wherein Figure 1 is a view partially in sectionand partially in elevation of the main features of a pressing machine,

Figure 2 upper portion of the toggle lever,

Figure 3 is a sectional view on the line of Figure 2.

In the embooiment disclosed, a suitable frame at is employed, provided with a bed or buck 5, over which is located a head 6 that is movable downwardly upon and ren'iovable upwardly from the bed 5. This head is carried by a swinging arm or lever 7 fulcrumed on the frame, as illustrated at 8, and counterweighted at 9.

The lever 7 and head 6 are actuated by a toggle mechanism, including an upstanding lever 10 fulcrunied at its lower end, and having its upper end reversely curved, this ourvature consisting of a rearwardly extendingportion 11, forming a recess 12 in its front side. Thelever terminates at its upper end in a rearwardly offset ear 13. A link 14, pivoted to the rear end of the arm or lever T, has a yoke 15 that embraces the till 13, and is pivoted thereto, a; shown at 16.

A yielding stop 17 is mounted on the frame, and is adapted to be received in the recessed portion 12 of the lever, this formation of the lever thus permitting the head to be elevated above the bed 5 to a relatively great height. The movement furthermore is permitted without interference on the part of the yoke 15 by reason of the offsetting of the car 13. An abutment element in the form of a plate 18 is mounted transversely on the rearwardly curved portion of the lever 11, and has an offset terminal 19 in line therewith. This plate is adjustable transversely of the lever and is adaptedto be held by bolts 20 that pass through openings in the plate and lever, either said plate or lever being provided with a series of is a "iew in elevation of the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size,shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:" v

1. In pressing apparatus, the combination with a bed and a head movable toward and from the same, a swinging arm supporting the head, operating means for the head, in-

cluding a toggle lever and a link connecting V the lever and arm, a stop for the toggle lever, said lever having arecessed portion that re ceives the stop, and an abutn'lent member adjustably mounted on the lever and pro-- jecting into the recessed portion thereof, said abutment member being adapted to engage the stop. I

2. In pressing apparz'ttus, the con'ibination with a bed and a headfmovable toward and from the same, a swinging arm supporting the head, an upstanding lever fulcrumed at its lower end and having a rearwardly curved upper portion forming a recess and a rearwardly offset terminal ear, a yoke embracing and pivoted to the ear and to the head carrying arm, a stop in advance of the lever and adapted to be received in the recess thereof, and an abutment plate adjustably mounted transversely on the rearwardly curved portion of the lever and adapted to be projected more or less into the recess and be engaged by the stop.

In testimony whereof, I affix my signature.

MORRIS RosENBLUM.
