Description

Flemington,
N. 3., a corporation of New Jersey Application October 1, 1942, Serial No. 460,405
2 Claims. (Cl. 164-23) This invention relates to presses, and is herein illustrated as embodied in a beam for clicking machines.
In shoe factories, use is commonly made of clicking machines'for cutting shoe parts from sheet material, such as leather. One type of such machine, which has come into extensive use, is that illustrated in United States Letters Patent No. 921,503, granted May 11, 1909 upon producing right and left blanks of the same size.
In the use of such dies, one of the cutting edges is placed in contact with the material to be operated upon, and the presser member of the machine is brought down upon the other edge, forcing the die through the material. If the surface of the presser member which engages the upturned cutting edge is too hard, it is like- 1y to cause die breakage. Consequently, it has striking plate upon the presser member, which can be penetrated slightly by the cutting edge during the pressure-applying operation, thus been the practice to make use of an auxiliary tending to eliminate breakage of the die, but
which at the same time is sumciently resistant to the wear caused by repeated blows struck by the presser member.
It is an object of the present invention to provide a beam of the type referred to having an improved striking plate which is highly resistant to wear and to rough usage and possesses other advantages. To this end and as illustrated, the invention provides a presser member having a base plate and a striking plate extending along the base plate and secured thereto by studs which are integral with the striking plate and extend through countersunk holes in the base plate. Preferably, the striking plate is composed of comparatively soft material, such as aluminum alloy, and is cast directly upon the base plate in such manner that portions of the metal flow into the countersunk holes in the base plate to form the securing studs. This construction is highly advantageous, for the reason that the studs securely hold the striking plate in position against the base plate, and any relative movement between the striking plate and the base plate is prevented by the studs, thus eliminating any likelihood of buckling of the striking plate when it is subjected to repeated shocks during operation upon the work.
These and other features of the invention are disclosed in the following specification and in the accompanying drawings, and are pointed out in the claims.
In the drawing, i Fig. 1 is a perspective View, partly in section,
of a clicking machine beam embodying the invention; and
Fig. 2 is a cross sectional view, along line II-II of Fig. 1, showing the means for securing the striking faceto the base plate.
The beam shown in Fig. 1 comprises a base plate In, and a body portion in the form of a hollow reinforcing shell l2, preferably of steel,
Welded together along their line of contact [4,
the base plate and the shell each being Welded to a bracket it, which is arranged to be secured to the post of a clicking machine by clamping members It and 2E]. The base plate IE] is provided with a striking face in the form of a plate 22, preferably of aluminum alloy, which is secured to the base plate by studs 24.
Preferably, the plate 22 is formed by casting it directly upon the base plate It, the beam being placed in a mold and metal caused to flow along the outer portions'of the base plate. The base plate is provided with openings 26, best shown in Fig. 2, the upper portions of which are countersunk with the result that during the molding operation metal is caused to flow into the openings, thus forming the studs 24 which are integral with the plate 22 and which intimately secure the plates H1 and 22 together.
The base plate It is provided with an adequate number of, holes 26 along its side and central surfaces, so that the plate 22 is secured there to at a large number of different points, thus and a new striking plate cast onto the base plate plate H].
Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. As an article of manufacture, a beam for presses having a body portion terminating in a base plate, openings extending through the base plate having countersunk portions on one side of the base plate, a striking plate cast upon the other side of the base plate, and members integral with the striking plate extending through the openings and completely filling the same for securing the striking plate in close relation to the base plate. v
