IMPROVED MACHINE FOR STAMPING GLAY DOOR-KNOBS'.

TO ALL WHOM I'I MAY CONOERN:
Be it known that I, GEORGE LAWTON, of Trenton, in the county of Mercer, and State of New Jersey, have invented a new and improved Machine for Stamping Clay Door-Knobs, Ste.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others 'skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification, in which--` Figure I, sheet 1, is a front elevation of my improved machine. i
Figure 2, sheet 2, is a vertical cross-section of the same, taken on the line :e a', iig. I.
Similar letters of reference indicate like parts.
'lhc object of this invention is to construct a machine whereby door-knobs and other articles of clay may be formed or stamped in the most simple and eiiicient manner, completing the door-knobs or other articles as far as the working in clay is concerned.
The invention consists in such an arrangement of the machine that the vstamping process may be perfect, the upper die falling down three times with variablc'force, so as to completely finish the article. The machine is also so arranged as to prepare the holes in theiknobs, or other articles, for the reception of the Shanks of said knobs or other articles, said holes branching towards the sides for the purpose of making the lead filling adhere.v
A represents the frame of the machine, consisting of upright posts and horizontal timbers and braces, and is made of wood or any other suitable material. Suitable boxes are arranged on the frame, and the horizontal shaft B is mounted thereon and receives rotary motion from a pinion, a, on the driving-shaft C, said pinion meshing into a gear-wheel, on the shaft B, as is shown in the drawings. To the shaft B are secured two or more sets of cams D, which are so arranged as to operate the dies alternately. Beds E are arranged on the front side of the frame A, upon which. beds the lower dies or matrices c are arranged and held by means of setscrews CZ, so that they may be removed and easily replaced. The upper dies e are secured to the hammers F, which are attached to the lower end of vertical sliding-shafts G, each ot' the latter being provided with an arm,f, which is operated by the cams D on thc shaft B. The ends of the hammers are grooved and fit over tonguesg, which are arranged on the upright of the frame A, as shown in fig. I, so that thereby the hammers are well guided.
For cach set of cams D on the shaft B is provided a shaft, G. 'lo each of the latter is secured a hammer, F, and each of these may hold two (more or less) upper dies e, the latter corresponding with the number of and beingy exactly above the matrices c on the beds E. The upper dies are removable from the hammer, as the matrices may be detached from the beds. y
By the revolution of the snaft B, the cam D comes in contact with the arm f, and thereby raises the shaft G. The matrices are then filled with clay,the shaft Gis then released from the cam, and the hammer falls upon the bed E, the upper dies and matrices coming together, and between them forming the clay into the required shape. l
Each set or series of cams D consists of three parts. The iii-st part, 7L, raises the hammer and dies e up, so that the upper surface of the hammer comes almost in contact with. the upper timbers of the frame A. The second part, z', raises the hammer half as high as h; and the third part, k. raises thesame half as high as z'. By the action of the cam 7L the hammer falls the greatest distance, which is reduced to halfby the cam z', and again subdivided by the action of cam 7c. The cam 7i has a surface of sucient extension to retain the hammer in its elevated position long enough to allow the removal of the finished knobs from and the insertion of clay for new ones into the matrices. The different motions of the upper dies are required to give tothe article the reduired and necessary finish.
To facilitate the removal from the matrices of thc ready-stamped knobs or other articles, I have arranged the pushers II, which arc tubes, closed at the top, extending through the matrices and beds E downward, and
Aconnected at their lower ends with eachother (those arranged in the same bed) by a horizontal connecting-rod, Z.
The saine is secured to the lower end of an upright rod, mi, the upper end of which is pivoted to an elbow-lever, n, which is pivoted at its angle to the frame A. From the side of the cam 7L projectsia side-cam, o, which pushes once during every revolution of the shaft B, and at the moment when the upper dies are being raised by the cam z against the vertical arm of the lever n, thereby raising the end of the horizontal arm of the same, and
also the rod m, bar Z, and pushers H, thus lifting the 4article outof the matrices and facilitating their removal. As soon as the action ofthe cam o on the lever n ceases, the'pushers are depressed again by means of a spring, s, which is fixed to the frame A, and acts upon pins or other projections on the bar Z.
The pushcrs are provided with a shoulder, as shown in iig. 2, which forms part of the bottom of the matrices, while the part projecting above the shoulders forms the holes in the knobs for the reception of the shanks of Said knobs, which said shanks are leaded into the knobs in the usual way.
The tubular pushers H work upon vertical rods p, which arc attached to horizontal timbers below the beds E.l To the inside of the pushers H, near their upper ends, are secured three (more or less) springs q, fig. 3, which operate horizontal pins 1, which pins pass through holes in the tubes H, The small horizontal holcs at the bottom of the main shank-hole of the knobs are' made by means of these pins r, which are either attached t to or-form part of the springs g, as shown in iig. 2. The springs q and pins r, which are secured to the inside of the sliding-tubes H, are operated by the stationary rods 'or pins p, the upper ends of which are made in thc shape of frusta of pyramids, as shown in fig. 2.
When the knobs are being stamped, the pushers H, springs q, and pins r are in position shown by dotted lines on the right-hand side matrices in g. 1, that is, the pushcrs aredown, and the springs are pushed out by the pins p, thus making the pins r project from the tubos H, so that by means of these pins the small horizontal 7holes at the bottom of the shank-holes of the knobs are formed. But as soon as the pushers H are elevated by the action of the cams o, levers n, rodslm, and bars l, the springs q are freed from the piup and draw the pins rl into the tube H, (as shown in figs. 1 and 2,) thus permitting the removal of the knobs from the matrices. As soon as the pushers are depressed again by means of the spring s, the pin p comes in cont-act with the springs q again, and the pins r are thus made to project again from the sides of the pushcrs. A
When articles are to be stamped which do not require to have holes formed in them, the pushers H may be replaced by others iuore simple in construction, whose oiiice will be simply to lift the stamped articles out of the matrices so that they may be removed from the machine. v
The forming of the horizontal holes at the bottomof the shank-holes in knobs, was heretofore very didicult, having to be done by means of drills. By my machine this portion ofthe work is greatlysimpliiied. By means of the threefold .action .of the cams upon the upper dies the stamping of the articles lin the matrices is greatly perfected, a much superior article being made thereby than by the machines now in general use.
What I claim as new, and desire to secure by Letters Patent, is-
l. The arrangement and construction of the cams D, whereby the dies e are operated three times in succession, the said canes consisting of the parts L, and c, all made and operating substantially as and for the purpose herein shown and described. I
2. The device for raising the pushers H so as to lift the stamped articles out of the matrices e, the said" devices consisting of the cams o, levers n, and rods m, all made and operating substantially as herein shown and described.
3. The spr-ing s, when arranged as herein shown and described, for thc purpose of depressing the pushers H as set forth.
4. The device for forming the small horizontal holes at the bottom of the shank-holes in door-knobs, said device consisting of' t'lie pins p, tubes H, springs q, and pins r, all made and operatingsubstantially as herein shown and described. Y I 4 GEORGE LAWTON.
