iland,have invented certain Improvements in Presses, of which the following description,

in connection with the accompanying raw-v ings, is a specification, like reference characters on the drawings indicating like parts in the several figures. l I

This invention relates to pressesof the member is movable relatively to a bed to e set a ressure ap )lying operation in connection t mmwith. resses of this type are used for many different purposes and frequently they are used-in connection with movable dies for dying out sheet material such as leather.

The invention isv shown as embodied in a machine especially adapted for employment for the purposes just specified, the illustrated machine being adapted especially for dying out thin sheet material such as skins of upper leather, and to machines intended for such uses the invention is particularly applicable, as will appear hereinafter.

Presses for dying out upper leather are preferably constructed so that a considerable surface of the leather being operated upon may be exposed, and so that the operator mayconveniently place a die upon any or-- tion of the exposed surface. To this en the stock supporting bed is usually of a width such that the operator. may conveniently reach across it to place a die uponany .part of its width and that he may conveniently inspect the stock within the die which is position over the die in the next'selecte location of the latter.

machine of-thetype of that just referred to is illustrated in Letters Patent of the United States, No. 921,503, dated 'May 11, 1909, and the present application is'a continuation of the application for said Let- 1 ters Patent, so far as said applications disclose commonsubject-matter. When a machine of the type of that shown in the said patentis constructed with a die blocker cut- BATES, a sub- 1 excess of weight, from drag ting bed of such a width and length as to permit convenient inspection of the stock lying upon it and convenient manipulation of the die thereover, a portion of an ordinary skin, such as those from which upper blanks are usually cut, will project over one edge of the die block and when the operator is cutting from the portion of the skin nearest to him it is necessary that a portion of the opposite side of the skin shall project over the edge of the die block remote from the operator; In the machine of the patent above referredto the pressure applying memberis connected to a support located behind the bed and in the specific construction therein shown this support. is a vertically reciproeating plunger to which the pressure applyin member-is secured. To facilitate handling of the material being operated upon and to prevent it from being injured or soiled by the machine, it is desirable to provide a recess between the bed and the support for the pressure applying member to receive such surplus material as may extend beyond the rear edge of the bed, and an important feature of the present invention is the provision not only of such recess but alsoof a material receivingtrough in said recess. Preferably this trough extends substantially the whole length of the bed.

Another important feature of the present invention is the provision of a material receiving trough between the bedand the support for thepressure applying member which 'is so shaped that it will cause the material to roll back upon itself toward the bed and thus further prevent it from coming into contact with said support orother parts of the machine. The trough is also useful in supporting the weight of the surplus stock and preventing it, through an mg the stock on the bed. .This function of especially advantageous when the operator is cutting blanks from the portion of the stock nearest to him or when he is dying out -blanks from large skins.

' 'Another feature of the invention is the provision of an adjustable and detachable ably of sheet metal, so that-it may readily be. given any desiredshape and'any deslred position inflrespect to the bed. Advantages of making this trough of sheet metal are material receiving trough formed prefer-.

the trough is the cheapness of construction, the above sug gested ready adaptability to the various uses to which the machine may be put and its lightness.

The trough herein illustrated comprises preferably a piece of sheet metal of a length substantially equal to the length of the bed bent into U shape in cross-section and having its rear part somewhat higher than the front part and incurved and outcurved for purposes hereinafter to be pointed out. Clamp members carried by the trough are arranged to engage flanges provided upon the frame of the machine at the rear of the bed, this method of attachment of the trough to the machine frame permitting the ready adjustment of the trough with respect to the bed and the plunger. The clamp members are preferably also so shaped-that the trough may readilybe removed .when it is desired to clean it or to replace it by another of different size or shape. The trough being formed of sheet metal, its shape, as above suggested,

may readily be changed to suit it to the different uses to which a machine of this type may be put.

Other novel features of the invention will be apparent from a consideration of the illustrated construction in connection with the description thereof, and it is my intention to cover, inthe annexed claims, all that is herein illustrated of my invention.

In the accompanying drawings,Figurel is a side elevation of a machine of the type of that disclosed in the patent, above referred to, having embodied therein theinvention of this application; Fig. 2 is a perspective detail, partly in section, illustrating the construction and manner of use of the stock supporting trough which forms the main feature of the present invention; and Fig. 3 is a sectional detail showing the manner of attachment of the trough' to the frame.

The press to which the invention is herein shown as applied comprises, preferably, a cutting bed 2 secured to or formed as part of a frame land adapted to supporhlthe skin or other material.5 to be operated upon by movable cutting knives or dies 7. Pressure applying means comprising preferably an arm 6 isarranged above the cuttingfbed, said means being'secured by bolts 8 to a column or plunger 10 supported in bearings I 12 and 14 on an upwardly extending portion 15 of the frame. The column or plunger 10 is arranged to turn in said bearings so that the pressure applying member may be positioned above the Work and dies or moved entirely clear of them by a movement of said means laterally in a plane substantially parallel to the bed. The pressure applying means and column are arranged to receive a vertical reciprocating motion so that when the said means is lowered into contact with the die or dieslresting u on the work, pres surewill beexerted an the work will be died out. When the said means is raised above the workit can be swung to a'position sufliciently removed from the ortion of the work being operated on .to a ord an unobstructed view of that part of the work, or it may be swung entirely clear of the bed. The vertical movement of the pressure applying means and its supporting column may be obtained through any suitable mech-' anism, such, for example, as that illustrated in the patent above referred to, said mechanism being operated from a driving pulley 20 which may be clutched at will to a shaft constituting a part of said mechanism. The clutch will be preferably of the type that imparts one revolution to the-driving shaft and then automatically disconnects.-' Provision will preferably be made for adjusting the pressure applying member vertically in order to accommodate it to different depths of cutting dies. An operating handle 36 cooperating with'a lever 40 pivoted upon the extension 15 of the frame at 42 is arrangedto operate the clutch and start the machine for effecting a pressure applying operation at the will of the operator through suitable connections 56, 58 and 62 with said clutch.

The foregoing mechanism, as well as that hereinafter described, is substantially the, same as that illustrated and described in the patent above referred to.

The cutting bed 2, which, in the preferred construction, comprises a wooden block,is preferably of such dimensions that the operator may conveniently place the die on any part thereof and' may inspect the stock .1

lying within the die, the die being-preferably formed entirely open within its outline. The block is therefore preferably of a width less than its length, the blocks employed in machines in commercial use being usually about 18 inches wide and 36 inches long. When a skin is. placed upon such a block a portion of it, at the start, will usually project beyond one of the sides of the block and, for convenience in manipulation of the skin and the dies it is preferable that the surplus project beyond the edge of the block remote fron th'e operator, particularly when the operator is cutting from the portion of the skin nearest to him. To provide. for this, the machine is preferably so constructed that there is a comparatively shallow recess between the block and the bearing 14 for. the column or plunger lO in which the surplus portion of the stock lying upon the cutting bed may be received, and preferably a throat or trough 33 is located in this recess to sustain the said surplus portion of the stock without soiling or wrinkling it. Preferably this throat 33 will be vsituated in front of the bearing 14 and the .verticaLcolumn 10 and will extend to either eeopac metal bent into substantially a U shape in cross-section, one arm of the U lying'just beneath the rear edge of the cutting bed 3 put and to the various the machine operates, and that by its method and the other arm of the U, which is some-i what longer than the. first-mentioned arm, lying adjacent to the bearing 14 and being recurved somewhat at its'upper end. The

recurving of the last-mentioned arm of the U or the back part of the trough 33 is ofadvantage "not only in holding the stock out of contact with the column orplunger 10 as it reciprocates, but in imparting to the stock asit comes into the trough a tendency to roll back "upon itself, thereby aiding-in preventing theformation of wrinkles, especially when operating upon stock such as patent leather.

The machine frame between the bearing 14 and the support for the cutting bed 2 is provided with lateral flanges 35 to which the trough is clamped by suitable clamps 37. Theseclamps are attached to the trough by clamping bolts 39' about which they may be turned to permit the convenient removal of the trough from the frame when it is desired to clean it, reshape it, or replace it by another.

It will be noted that the trough may readily be adjusted longitudinally of the flanges to place it in different relations to the bearing 14: and the cutting bed' 2;"that, being formed of sheet metal, it may readily be reshaped to permit its being suited to the various uses to which the machine may be materials upon which of attachment it may be readily removed for cleaning or to permit its replacement by another trough of. a different shape or Size or both.
