ERNEST T. LUNDQUIST, OF CHICAGO, ILLINOIS, ASSIGNOR TO ILLINOIS MODERN MACHINE COMPANY7 OF CHICAGO, ILLINOIS.

BUTTON -MAKING MACHINE No. 91s,177.

To all whom it may concern:

Be it known that I, ERNnsT F. T. LUND- QUIs'r, a citizen of the United States of America, and a resident ol' Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Button-lvlalring Machines, oi which the following is a specification.

My invention relates to presses such as are commonly used in making buttons composed of a plurality of elements and has for its object improvement in the construction and operation of its various parts, and especially to the means for controlling the position oi the die on the upper head.

In the accompanying drawings Figure i is a side elevation oi the machine, Figs. 2 and 8 are sections on li'ne 2 3 of Fig. l showing i the parts in two positions; Fig. 4 is a perspective view of the die-controlling arm; and Fig. 5 is an enlarged section on line 5--5 of Fig. 4.

In the said drawings A is a base to which is secured a vertical pin B (Figs. 2 and 3) by means of a dowel A1 (Fig. l). At the upper end of the pin B is secured a head piece C by means of a second dowel A2. Pivoted on the pin B, between the base A and the head C, is a swinging die-holder D, upon the lateral arms D1 oi which are the lower dies E and El. Between the base A and head B is a second pin F secured to base and head by suitable dowel pins. This second pin F acts to strengthen or stiflen the connection between head and base, and also to limit the movement of die-holder D by engagement between it and the arms D1.

In guides in the head C is a reciprocating plunger G normally held in an elevated position by the spring G1. A cam-lever Il serves to depress the plunger G. Slidably mounted on the lower end of the plunger G is a die G2, the upward movement of which is limited by a collar G3 rigidly secured to the plunger G.

Pivoted in a hole in the plunger G is a controlling arm J, the lower' end J2 of which is adapted to swing into contact with the lower part of the plunger G between the collar G2 and the upper die G2. Vhen the arm J is in this position the die G2 is prevented from sliding on the plunger rod G, but when the arm J is moved away by being swung on its pivot, the die G2 is free to move up to the collar G3. At the upper end of the arm J isa small transverse cut J1 in which the upper.

end of the spring G1 rests. This cut has alat (see Fig. 5) surface against which the spring G1 presses, and this surface is so shaped or inclined relatively to the arm itself that the upward pressure of the spring G1 acts to hold the lower part J2 into contact with the plunger G. The engagement of the spring G1 with the notch or cut J1 prevents the arm J 'from slipping out oi its bearing in the plunger G. It will be apparent that by pressing the spring Gl downward slightly by hand the arm J may be freely removed.

The die-holder D and its arms are in the shape of a sector, and on one of the arms D1 is a vertical pin K, the upper end oi which is adapted to engage the tip J 2 at the eXtreme end of the arm J. Vllhen the die holder I) is swung into the position shown in Fig. 3 with the lower die E under the upper die G2, the pin K strikes the tip J3 to swing the arm J on its pivot and move the curved part J2 from between the die G2 and the collar G2. In this condition, when the cam-lever Il is moved to `force the die G2 against the lower die E, the upper die G2 will slide up on the stem or plunger G. I.lf/'hen the die-holder I) is swung into the position shown in Figs. l and 2 with die El under die G2 the pin K will be removed and the spring G1 will bring the part J 2 between die G2 and collar G3 and prevent such sliding of the die G2 when the plunger is depressed.

It will be observed that by pivoting the controlling arm J upon the plunger G the lower or controlling part is always in the proper vertical position to swing into the space between collar and die G2 irrespective of the vertical position oi the plunger G. This is a mattei' of considerable convenience in operation as compared to similar devices now used. It will also be observed that the lower die frame is pivoted to swing transversely on the upright standard which holds the head C and plunger G, and that in swinginfr on this pivot the amount oi movement is limited by another part of this standard. That part oi' the standard which consists of the pin F is so related to the arms D1 of the die-holder D, that when moved to one extreme one lower die is directly under the upper die, and when moved to the other eXtreme the other lower die is under the upper die. This is a superior form of construction both in convenience of operating and in the general appearance of themachine.

What I claim is:

l. In a machine of the character described, a base, a standard consisting of Aa pin secured to said base, a head secured to the upper part of the said pin, a vertically movable member supported by and guided in said head, a frame mounted upon said pin between the base and the head andarranged to swing about said pin as a center, a stop for limiting the movement of said frame, said stop constituting a .Supplementary part .of the standard, and -a plurality .of other members for cooperating with the vertically movable member' supported on said frame and an ranged by the movement of the frame on its pivot.

In a machine .0f the character described, a vertically reciprocating plunger, a spring operating to cause vSaid reciprocations in one direction, Aa die ,carried by said plunger and movable thereon, and a controlling member carried by said plunger and arranged to prevent said die sliding thereon, said controlling member being normally held in operative position by said spring.

3. In Aa v'machine of the .character described, a vertically reciprocating plunger, a spring operating to cause `said recipiocations in one direction, .a die carried by said plunger and movable thereon, a controlling member carried by seid plunger and arranged .t0 prevent Said die Sliding thereon, said controlling member beingnormally held in operative position by said spring, a plurality of other dies arranged to be brought successively beneath the first mentioned die, and means associated With the last mentioned dies for moving said controlling member out of operative 1position. Y

4. ,In a machine of the character described, a vertically reciprocating and sliding die, a member for controlling the sliding action of said die, and a spring operating to reciprocate said .die in .one direction and also operating to normally hold said controlling member in operative position.

5. In machine of the character described, a vertically reciprocating plunger, a die ar-V ranged to reciprocate with said plunger and to slide thereon, a spring for normally holding said plunger' `at its upper position, and a device pivoted on said plunger and operating to control the sliding of the `die on the plunger, said y device being provided with. a notch engaged by said spring whereby the spring acts to hold the device in operative position.

.6.. In a machine of the character described, a vertically reciprocating plunger, ya spring i'or normally holding said plunger in its upper position, a die carried by and slidabl'e on said plunger, and a device pivoted ,on said plunger and normally held by said spring in a position to prevent said die sliding on said plunger,
