HAT-PREVSSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 636,392,dated'l\lovember 7, 1899. Application filed May 2, 1899. Serial No. 'll5,348. lNo model.)

To all whom it may concern: Be it known that I, FRANK H. VAN HOUTEN, a citizen of the United States, and a resident of Fishkill-on-the-Hudson, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Hat-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 letters of reference marked thereon.

This invention relates particularly to improvements in presses such as are specially adapted for pressing hats in the manufacture of the same, and while designed especially for such use it is obvious that it may be usedfor like purposes in other lines of manufacture.

The object of the invention is to provide a simple, powerful, and easily manipulated press which may be set readily and quickly by the operator when the dies or forms are changed or the character of the goods operated upon is varied, to which end it consists in certain novel details of construction and;

combinations and arrangements of parts, all as will be now described, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a front elevation of a single machine embodying my present improvements. Fig. 2 is a vertical section, partly in elevation, taken from front to rear of the same. Fig. 3 is a view corresponding to Fig. 1, showing the handle or lever. in its reversed position with the platen raised. Fig. 4 is a detail section through the platen and showing the upper end of the spindle.

Like letters of reference in the several figures indicate the same parts.

, The machine illustrated in the accompanying drawings and in connection with which I have shownv my present improvements is a single machine having side frames A, with a top cross-piece B, a bottom cross-piece G, and an intermediate horizontal frame D, these parts being, however, so constructed as to adapt the frame for use as one of a series connected side by side, the side frames A in such instance forming the frame for adjacent machines, each, however, in its operation being preferably independent, and therefore in the present case I have deemed it expedient to illustrate only one.

a vertically-movable central spindle E, upon the upper end of which a platen F is supported, preferably in such manner as that the platen may have a slight rocking movement. The preferred manner of mounting is illustrated in Fig. 4, wherein it will be seen that the, platen itself is provided with a rounded socket f, and the upper end e of the spindle is correspondingly rounded to fit therein,

while immediately below such rounded porjtiouithe diameter of the spindle is reduced somewhat, as indicated at 6, thereby allowing the platen a limited rocking movement;

but should it be desired to employ a platen which Will not rock and at the same time be capable of rotation on the spindle the socket in the platen may be made somewhat deeper or the surrounding wall of the socket extended downwardly past the reduced portion of,

the spindle, as indicated in dotted lines at c in said figure.

The spindle E slides vertically in the bearings c d, and at its lower end, preferably above the bearing 0, it is threaded through a nut G, and to this nut the power mechanism for reciprocating the spindle or raisin or lowering the platen is applied, as well as the counterbalancing mechanism, when such is employed. The power mechanism in the presentinstance consists,primarily,of a forwardlyprojecting shaft H, mounted in a bearing I on the intermediate frame D and having at its outer end a socket h for the reception of a handle or lever H. At its inner end the shaft is provided with a crank-arm H and extending between the end of the crank-arm and the nut G and pivotally connected with each is a connecting-link H The half-rotation of the shaft, it will now be apparent,will swing the crank-arm H from its lowermost position to its highest position and will move the central spindle and platen correspondingly, and in the preferred construction the operating handle or lever is normally arranged to stand horizontal when the crankarm is in its lowermost position, being adapted to make a half-turn in swinging the crankarm to its upper position, and in the latter position the crank-arm is preferably carried slightly past its dead-center, where its motion or forward movement may be arrested by an adjustable stop, such as the set-screw K, where it will be held by the pressure of the platen and will not tend to return to its lowermost position until its movement is inaugurated through the medium of the operating handle or lever.

In addition to the bearings c and d, before referred to, the central frame and bottom cross-piece are also provided with bearings c and d, in which works a vertically-movable auxiliary spindle K. This auxiliary spindle K is also connected with the nut G, as shown clearly in Fig. 1, and at its upper end it carries or is connected with a clamp L, said clamp being adapted for engagement with the central spindle E. In the preferred arrangement the clamp takes the form of an open band or casting, which surrounds the spindle E, and at its two extremities is adapted to be drawn together by means of a screw and handwheel M, the arrangement being such that the central spindle may be firmly clamped, so as to prevent its rotation. The central spindle is also preferably provided with a hand-wheel N, by means of which when the clamp L is loose it may be adjusted vertically through the nut G, and thus give a variable range of movement for the accommodation of dies or forms of different shapes, and when so adjusted it will be locked in its adjusted position with relation to the nut by means of the clamp and hand-wheel L and M.

For convenience and ease of manipulation the central spindle and parts connected therewith are preferably counterbalanced by means of a counterweight 0, attached to one end of a flexible connection or chain 0,which chain after running over a pulley or guide 0 is connected to the nut G, as shown clearly in Fig. 2. y

In the operation of the machine it will be understood that the platen F cooperates with a form or stationary platen which is su pported by the top cross-piece 13, although I have not deemed it necessary to illustrate such cooperating platen, inasmuch as its shape and form are varied to suit the particular work being done, and it will also be obvious that the platen F illustrated may be changed or other platens substituted therefor adapted to cooperate with different styles or shapes of stationary platens.

The auxiliary spindle E in addition to holding the central spindle in its adjusted position, as before described, also prevents the rotation of the nut G upon the spindle under the influence of the connecting-link when the power is applied. Thus the parts are held in correct alinement throughout the whole sequence of movements, and any binding or distortion in the bearings is prevented.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is-
