Application filed January 17, 1914.

To all whom it may concern:

Be it known that we, Oscar: ll. W'nsrnniiisnn and l VILLIAM P. Jones, citizens of the United States, residing at St. Louis, State of ltlissouri, have invented certain new and useful Improvements in Presses, of which the following is a full, clear, and exact deseription, reference being had to the zceompanying drawings, forming a part hereof.

Our invention has relation to improvements in presses; and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

lln the drawings, l igure 1 is a face elevation of the press; Fig. 2 is a vertica ti n vcrse section thereof on the line 2-2 of Fig. 1; F 3 is an enlarged cross-section on the line 33 of Fig. 1; l is a vertical sectional detail taken through the loop or strap forming the passage-way in which the lockinp; member is hinged, the parts being in normal or righted position, and the lever arms of the locking members being shown dotted; Fig. a similar section with parts turned upside down; and Fig. 6 is a pen spective of the locking member detached.

The invention is primarily directed to devices employed for pressing a number of shoe out-soles with their complement of slips or layers which constiti'lte the linings therefor, the slips being first applied to the soles with a layer of cement or suitable adhesive, and then placed into a press and squeezed to secure a firm adhesion between said soles and slips. The invention however, is not restricted in its application, and may be used on any character of stock or material to be compressed.

The object of the invention is to construct a press which may be quickly adjusted to the stock operated on, and the final pressure he quickly imposed thereon after the adjust ment, as will fully appear from a detailed description of the invention, which as follows Referring to the drawings, 1 represents a ll-shaped member the arms whereof are pro vided with loops or straps 2, and forming; with said arms suitable passages for the traverse oi the arms of a complementary telescoping ll-shaped member 1, the outer faces of the arms of said complementary member being provided with transverse corrugations a. Mounted rotatably in the side Suecillcation of Letters Patent.

walls of the straps 2, about axes disposed parallel to the longitudinal axes of the corrugations (L are rocker-rods el; terminating in outer lever arms i, the weight of which normally tends to cause the arms to drop when the press is held in such position as to make the member 1 the bottom member. The cross-section of the rod i (with the exception of its terminals) is sul'istantially that of a semi circle, the rod being thus provided with semi-cylindrical walls tern'iihatingin a hat face 112. l heu the press is held or set up to malce the member 1 the bottom illfllllllel, the arms at will drop substantially as shown in Figs. 1, 1-, causing the faces m to dispose themselves in downwardly and inwardly inclined planes, said sloping; faces being thus brought into locking engagement with the adjacent portions of the corrugated formations, and thereby supporting the member 1 in any position to which it may have been moved in the passage-imys formed by the straps 2-. The members i l, l, act as bent levers, the long and weighted leverarms st extending outwardly from the axes of rotation of the rods l, and the short lever-arms being those portions of the rods at which are disposed on the opposite sides or said axes. The member 1 may therefore be regarded as being; supported from the short lever-arms oi the IllQll'llJQlS 1-, it. 11 we exert material pressure on the member 1 so as to cause a depression of the said short lever arms, the long arnr will swing upward (see dotted position Fig. i) causing the faces m to dispose themselves substantially parallel to the adjacent faces of the arms of the member 1, thereby escaping locking engagement with the rounded faces oi the corrugations and allowing the member 1 to be driven toward the member 1, and thus contracting the press it convenient points on the straps 2 are located arresting pegs or pins 5 in such position that when the press is turned upside down make the member 1 the upper member) the arms 1" will drop so as to be arrested by the pegs 5 when the faces m of the rockerreds lassume [)tllflllQllSln with the adjacent faces of the arms of the member 1'. With the faces in in this position it obvious that the member 1 may be readily withdrawn out of the sockets or passageways termed by the straps 2, or pulled outwardly so as to expand the press to any desired de- (so as to gree. Coupled to the upper cross-bar of the member 1 is a follower plate 6, the connection being effected by means of staples 7 which allow the follower a limited play to and from said crossbar. Operating through the cross-bar and engaging the followerplate is a press-screw 8 provided with a hand-wheel 9. Normally the screw 8 is unscrewed so as to permit the follower-plate to be lifted against the cross-bar, the latter being subsequently driven against the stock S inserted between the telescoping members 1, l, of the press, as more fully described in the description of the operation of the device, which is substantially as follows:

Let us assume that the members 1, 1, are expanded or dilated to admit a certain quantity of stock S between them. The stock is then placed between the members 1, 1, and the member 1 (normally the top member) is pushed down upon the stock until the follower plate 6 which bears against the crossbar of the member 1 is in firm contact with the adjacent end of the stock. As previously pointed out, the contraction of the members 1, 1, is readily accomplished, the necessary pressure being brought to bear against the member 1 to overcome the leverage of the weighted long lever arms 4: and bring the faces on of the short arms out of locking engagement with the corrugations a. When the follower 6 is well against the end of the stock, the final pressure is brought on the stock by a turn or two of the screw 8 which drives the follower plate onto the stock, the latter being thus firmly gripped between the follower plate and the cross-bar of the bottom member 1. When the stock has set or the work of compression has been accomplished, the press is turned upside down, allowing the arms 4 to drop against the pins 5 thereby bringing the faces m out of locking engagement with the corrugations a, when the press may be readily adjusted to allow the stock to be removed. The crossbar of the bottom member 1 is provided with a suitable platform P for the support of the stock, the follower 6 being provided with a late P coextensive therewith so as to distribute the pressure evenly through the stock. The member t acts as a locking cam for an upright position of the assembled sections 1, 1, (Fig. 1) preventing separation of the sections by the grip of the cam on the corrugations a of the section 1, but allowing the sections to be pushed toward one another (Fig. l). With an inverted position of the sections, this cam swings out of engagement with the corrugations a, the weighted lever arm a rotating the cam to the position indicated in Fig. 5, the arrest of the lever 1 at the proper point being accomplished by the pin 5.

Having described our invention, What we claim is 1. In combination with a pair of members connected telescopically with one another, a cam operating to grip one of the members and prevent movement between the members in one direction for a given position of the assembled members, and for releasing said members for an inverted position of the members.

2. In combination with a pair of U- shaped members having arms in telescoping relation, the outer faces of the arms of one member being provided with transverse corrugations, a cam mounted on each arm of the opposite member for engaging the corrugations with a given position of the assembled members, and a weighted lever-arm leading from said cam for rocking the cam out of engagement with said corrugations upon an inversion of the assembled members.

3. A press comprising a pair of U-shaped sections having arms operating telescopically, a strap on each arm of the lower section forming a passage-way for the traverse of the arm of the upper section, the outer faces of the arms of the upper section being provided with transverse corrugations, a locking cam substantially semicylindrical in cross-section mounted on each of the arms opposite the corrugations aforesaid, a weighted lever arm leading outside the press from one end of the cam and adapted to oscillate the cam into locking engagement with the corrugations for an upright or normal position of the assembled sections, and to rock said cam out of locking engagement with an inversion of the assembled sections, and a limiting pin on each of the straps for arresting said lever arms at the proper point to insure such disengagement.

In combination with a pair of U- shaped telescopically operating press-sections, a platform on the cross arm of one of the sections, a follower suspended loosely from the cross-arm of the opposite section, a screw on said cross arm for actuating said follower, and a plate on said follower cooperating with the platform to hold a charge of stock between them.

5. In a press provided with a pair of relatively adjustable sections, levers pivoted to one of the sections and presenting their short lever-arms to the opposite section, whereby the latter section becomes suspended from said short arms.

In testimony whereof, we afiix our signatures, in presence of two witnesses.
