CUTTING PRESS.
No. 415,477. Patented Nov. 19, 1889.
UNTTED STATES PATENT OFFICE.
ARLIN V. STEVENS, OF CUMMINGTON, MASSACHUSETTS.
CUTTING-PRESS.
SPECIFICATION forming part of Letters Patent No. 415,477, dated November 19, 1889.
Application iiled January 10, 1889. Serial No. 295,949. (No model.)
To all whom t may concern:
Be it known that I, ARLIN V. STEVENS, a citizen of the United States, residing at Cummington, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Outting Presses, of which the following is a specification.`
This invention relates to the man nfacture of brush-handles and of other flat articles made of wood, the object being to produce such articles by cutting them from iiat pieces of wood by the method hereinafter set forth.
In the drawings accompanying and forming a part of this specification, Figure 1 is a front elevation of a machine embodying my improvements. Fig. 2 is a sectional side elevation of the same in line a a, Fig'. 1. Fig. 3 is a horizontal section in line b I), Fig. l. Fig. 4. is a similar view in line c c, Fig. 1. Fig. 5 is a vertical transverse section through the cutting -knives, showing the upper knife raised.. Fig. 6 is a similar view, showing the said knife at its lowest position.
Similar characters designate like parts in all the figures.
The frame-work of my improved cuttingpress consists of a bed-plate A and two uprights B O, provided with ways 2 and 3, respectively, for the press-slide D. The crankshaft N is carried in ordinary bearings on the top of the uprights B O. It is provided with a pulley I), whereby it may be revolved with an eccentric E for actuating' the plunger, and has cranks G and 8 for communicating through any suitable connections the proper reciprocating movement to the press-slide. Said connections consist or may consist of the two similar and well-known connectingrods 10 and 12, fitted to said cranks, respectively, and connected at their lower ends by pivot-pins 11 13, respectively, to the adjustment stems or rods l1 16, which rods fit in holes in the upper plate 20 of the press-slide, and are adjustably fixed therein by the pairs of nuts 15 17 and 19 21', which are fitted to those threaded stems. By this means the slide is readily adjusted to the required position in the machine. The upper and lower plates 2O and 22 of the slide D are connected about centrally by a boss or hub 24, which forms a bearing for the plunger-stem 25, that is connected by the pivot-pin 27 to the eccentricrod 26 of the eccentric E.
The cutting-out knives are two in number, and are secured, one on the bed A and the other on the under side of the slide D. These knives are similar to those used for cutting leather in the manufacture of shoes, and should be constructed integral of good steel well tempered. The cutting-edges of the knives being tapering' and usually brought down to a thin edge, about as shown, I fit upon each of them and rigidly secure thereto a plate or knife-holder for holding the knife in place in the machine and for resisting the strong tendency of the knife to spring out of proper shape or outline during the cutting out of a brush-handle. The upper and lower knife-holders are designated by 30 and 32, respectively, and are formed to accurately fit around or inclasp the upper and lower knives 33 36, respectively. The said knives are securely held into their holders by a series of horizontally-placed rivets 9. (See Figs. 5 and 6.) One of the knives (the upper one, as shown in the drawings) is made somewhat smaller than the other, so that its edge may enter within the edge of the other knife (see Fig. 6). when the press-slide is at its lowest point. The knife-holders are held in place by the bolts 7, which are substantially the same as those commonly used to hold in place the die-holders of ordinary punchingpresses. The lower knife stands over, or,
' rather, it surrounds, the opening T in the bed A, which opening is slightly larger than the area of the upper edge of the lower knife. Within the upper knife there is a follower or plunger 40, rigidly affixed to the stem 25 andv fitted to slide freely, but preferably closely, in said knife.
In operating the machine the piece of wood or like material 50, from which the article 55, Fig. (3, is to be cut out, is placed over the lower knife as shown in Fig. 5. The crank-shaft being now revolved, the upper knife descends and cuts into the wood, at the same time driving down the wood onto the lower knife, so that the cutting out is done about equally from each side of the piece 50, thereby balancing the strains in the material and preventing the piece cut out from being split by such strains. Owing to the peculiar construction and arrangement IOO of the knives, whereby one enters the other as set forth, the piece 55 is out out entirely free from the plate 50, even if said plate or board is of a somewhat tough and fibrous character, as many kinds of woods are. The eccentric E is adjusted on its driving-shaft N in such manner as to bring the plunger down onto the wood at about the moment the knife 35 reaches its lowest point, as shown in Fig. 6.- This is accomplished by setting the center of said eccentric back of the cranks, so that the plunger follows the movement of the slide and is a little later in reaching the corresponding points of its stroke. In practice, the frame-work and also the slide D (though each shown integral in the drawings) may be made in more than one piece.
Having thus described my invention, I claiml. In a cutting-press, the combination of a frame-work, a press-slide, actuated substantially as described, and two cutting out knives of corresponding outline, one placed on the press-slide above and coinciding with the other knife, said knives being each brought to a thin edge of substantially equal taper, whereby the cutting out is done substantially equally from each side of the piece operated upon, substantially as described.
2. In a cutting-press, the combination, with a frame-work, of the lower knife supported thereon, the press-slide, the upper knife carried on said slide, and the plunger working within the upper knife and operating to drive the cut-out piece downward within the lower knife, all substantially as described.
3. In a cutting-press, the combination, with the frame-work, of theslide D, crank-shaft N, the knives 35 and 36, the plunger, and connections operating said slide and plunger from said shaft, all substantially as described.
4C. In a cutting-press, the combination of the lower knife supported substantially as described, the press-slide actuated substantially as described and carrying the upper knife, the stem 25, sliding within said press-slide, and the plunger 40 on said stem, all arranged and operating substantially as described.
