UNITED STATES PATENT OFFICE.
. SEAL-PRESS.
Application filed. January 24, 1920.
To all whom it may concern:
Be it known that I, CALDER C. Grnson, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in SealPresses, of which the following is a specification.
This invention relates more particularly to the class of hand presses employed for compressing lead car seals after threading the customary wire shackles through them, such presses usually comprising a head or frame'having a die bed, a stationary lower die seated thereon, a lever carrying the upper movable die and a cam-lever acting upon said die carrying lever. One of the objects of my invention is the improvement ofthe press with a view to simplifying its construction, increasing its strength and reducing its cost of manu facture and firmly supporting and bracing the lower die.
" A further object is the provision of simple and convenient means for adjusting the lower or stationary die to compensate for wear of the parts.
In the accompanying drawings: Figure 1 is a-side elevation of a seal press embodying the invention. Fig. 2 is a vertical longitudinal. section thereof. Fig. 3 is a perspective front view of the head or frame of the press. Fig. l is a perspective rear view thereof. Fig 5 is a front elevation of the press. Fig. 6 is a horizontal section on line 66, Fig. 1. Fig. 7 is a horlzontal section on line 7-7, Fig. 1. Fig.8 is an enlarged perspective view of the lower die. Fig. 9 is a similar view of one of the washers. Fig. 10 is an enlarged cross section on line 1010, Fig. 2.
Similar characters of reference indicate corresponding parts throughout the several views.
10 indicates the head or frame provided in its front side with the usual recess 11 to form the projecting bed or seat 12 for the lower die 13.
14 indicates the usual lower lever carrying the upper die 15, and 16 the upper lever having the cam 17 which bears upon the head of the lower lever, to cause the upper die to approach the lower one when the handles of the two levers are pressed toward each other in a manner common to this class of presses. The front arm of the die-lever is elevated by the customary spring 18.
Specification of Letters Patent.
Patented Oct. 18, 1921.
Serial No. 353,804.
The frame 10 is chambered or bifurcated to receive the front portions of these lever. which are fulcrumed upon transverse bolts 19, 20 passing through the sides of the frame. The frame 10 is preferably stamped from a single blank of sheet steel or other suitable metal and comprises side walls 10, 10 which are spaced apart to admit said levers and are connected together at their lower edges by a bottom web 21 extending from their front nearly to their rear edges. The lower front portions of these side walls located below the recess 11 are connected by a curved front web 22, the upper edge of this web and the adjoining portion of the side walls forming the approximately semi-circular seat 12 for the lower die. This seat is depressed below the adjacent portions of the side walls to form abutments or shoulders 23 against which the rear side of the lower die abuts, thus positively holding it against rearward displacement.
Extending downwardly from the bottom of the lower die is a hollow, internally threaded stem 25 which is seated in the socket formed by the front web 22 and the side walls of the frame. A screw 26 passing through a hole 271 in the bottom-web 21 and engaging said threaded shank serve-s to clamp the lower die tightly upon its seat. This screw also permits adjustment of the lower die to obtain the proper pressing action of the dies and to compensate for wear of the cam face 17 or other parts. To take up wear, the screw and the lower die are removed and one or more washers 27 are applied to the die stem 25 after which these parts are replaced in the press and the screw is tightened. clamping the washers between the lower die and its seat and raising the die to the proper position or elevation relatively to the face of the movable die.
In the preferred embodiment of the press shown in the drawings, the lower front portion of the frame which forms the die bed is contracted or somewhat narrower than the remainder of the frame transversely of the plane thereof, and the side walls are provided in their outer sides. in line with the abutments 23 with vertical indentations 28, whereby the rear portions 29 of the semicircular die seat 12 are bent or displaced inwardly far enough to resist rearward displacement of the die-stem, thus effectually guarding against tilting of said die on its seat and retaining it squarely thereon, as
- side strains.
Any appropriate means may be employed to prevent rotary displacement of the lower die on its seat. In the preferred construction shown in the drawings, this is accomplished by providing the washer or washers 27 on both faces and at opposite sides of their central opening with radial ribs or projections 30, 31 which interlock with corresponding recesses 32, 33 formed in the opposing faces of the die-bed, and the lower die, respectively.
A stamped press frame such as herein shown and described is very simple in con struction, possesses great strength and can be produced at comparatively low cost.
I claim as my invention:
1. In seal press, the combination of a headcomprising spaced side walls formed with a die-bed, the portion of the head carrying said die-bed being narrower than the remainder thereof transversely of the plane of the head and depressed below the adjacent portions of said side walls, forming rear abutments, a lower die-seated on said bed against said abutments and having a stem seated in the narrowed portion of said head, an upper die cooperating with said lower die, and means for moving the upper die relatively to the lower one.
2. 111 a seal press,the combination of a head stamped in one piece from sheet material and comprising spaced side walls formed with a die bed, a lower die seated on said bed and having a stem extending below said bed, said walls-being indented on the rear side of said die-stem, forming inwardly displaced portions which prevent rearward displacement of said stem, an upper die 00- operating with said lower die, and means for moving the upper die relatively to the lower one.
3. In a seal press, the combination of a head stamped in one piece from sheet material and comprising spaced side walls formed with a die-bed, the portion of the head carrying said die-bed being narrower than the remainder thereof transversely of the plane of the head and depressed below the adjacent portions of said side walls, forming rear abutments, a lower die resting on said bed against said abutments and having a stem seated in the narrowed portion of said head, said walls being indented on the rear side of said die-stem, forming inwardly displaced portions which prevent rearward displacement of said stem, an upper die cooperating with said lower die, and means for moving the upper die relatively'to the lower one.
4. In a press of thecharacter described, the combination of a head havinga die-bed, a die seated on said bed, the die and bed being provided in their adjacent portions with recesses, and a washer interposed between the die and the bed and provided on its upper and lower sides with lockingprojectionsengaging said recesses, respectively.
5. In a press of the character described, the combination of a head having a die-bed, a die seated on said bed, said die-bed being provided in its upper edge at one side thereof'with a recess and said die' being provided in its lower edge on the opposite side of the 7 CALDER o. GIBSON.
