Application filed October 30 1926. Serial No. 145,303.
The purpose of this invention is to provide an improved construction of a nature of a pedal operated press of the general character common for light die and press work such as button making, particularly adapted for accommodating the limbs of the operator in the swinging movement of the pedal, and providing a seat for the operator hinged to the press frame for swinging to adjust the pos1- tion of the seat to the operators convenience in view of the pedal movement, and at the same time rendering the seat stable in position as adjusted for thus-accommodating the operator. It consists in the elements and features of construction shown and described as indicated in the claims.
In the drawings Figure l is a plan view of a press and con nected operators stool embodying this invention.
Figure 2 is a side elevation of the same.
The structure shown in the drawings comprises a die press which is in general of familiar construction comprising the standard A upon which is mounted the press proper, B,
having the reciprocating head, Bfiactuated for working stroke by the lever, B which is connected for deriving its operating movement by means of a link B, which is connected for actuation by the pendulons pedal member, C. One characteristic of the invention consists in the form of this pendulous pedal member which, being fulcrumed at its upper end on the press standard, A, as indicated at c, is formed with a rearward bend at about one-third of its length downward from its fulcrum at a, as seen at C the pedal terminal or foot rest, G being upturned from the lower end of said pendulous member, and the operating link, 13?, being pivotally connected at its lower end to the pendulous pedal substantially opposite the bend, C where a forked lug is provided as seen at 0 It will be clear that the pendulous lever being fulcrumed ate and pivotally connected at c to the lower end of link, B is, in effect, a bell crank lever for transmitting the operating motion at right angles. The purpose of this bend in the pendulous pedal will be understood to be to accommodate the knee of the operator, so
that the operator may be positioned close to the press without being obliged to swing the knee aside to avoid collision with the pendulous pedal in the forward swinging movement, or as the only alternative, adjusting the seat at such distance back from the press as to compel the operator to bend over forwardly in order to be in a position to observe the work. 1
In conjunction with the press having this knee-bent pendulous pedal, it is desirable to mount the operators seat on the pedal frame a operator, tends to swing the operators seat back from the press and requires re-adjustment by the effort of the operator after each pedal stroke. This objection to the hinged and swinging seat is overcoine in the construction shown which comprises the swinging seat bracket, E, pivoted vertically for horizontally swinging to the fixed bracket, F, bolted in a fixed position to the press frame, A, the seat, G, having its spindle, G mounted for vertical adjustment in the end of the swinging bracket, E, said swingingbracket being provided with a leg, H, of proper length to rest upon the floor upon which the press frame stands. It will be recognized that with this construction the weight of the operator upon the seat tends to hold both the seat and the press frame firmly positioned on the floor against any tendency of movement of either the seat or the press, which might otherwise result from the operating stroke of the pedal by the thrust of the operators foot forward, that is, away from the seat.
In order to afiordsome range of adjustment to accommodate the length of'limb and other bodily proportions of the operator and permit variation according to the preferencev of the operator in respect to position of the are through which the operators foot resting on the pedal swings in actuating the press, the link, B is provided with a plurality of pivot holes, 10, at short distances apart, and the fork lug, 0 has also a plurality of pivot holes, 12, at short distances apart, and within limits any pivot hole, 10, may be re 'istered with any pivot hole, 12, for receiving the pivot bolt, thereby permitting a very considerable choice in Mi a...
as to position of the are in which'the pedal will sW1ng,-t-hat is, whether nearer to or farther from the seat. And similarly, to accommodate the length of limb of the operator, the seat bracket, E, is arranged for attaching the seat G adjustabl'y by means of a T-fitting, K, which has a horizontal stem for insertion through a horizontal socket or aperture in the bracket, E, the cross, K of this T-fitting being bored to receive the seat spindle, G and set screws, 20 and 21, being provided for respectively securing the stem of the seat at vertical adjustment in the T- fitting and securing the stem of the T at hori- 15 zontal adjustment in the bracket arm, E.
