MACHINE FOR MAKING TYPE-BARS.
SPECIFICATION formingpart of Letters Patent No. 591,777, dated October 12, 1897.
Application filed October 10, 1894. Serial No. 525,505. (No model.)
The object of the invention is to provide a machine simple in construction and rapid in operation, which is adapted to automatically form type-bars from a supply of previouslyprepared matrix-blocks.
The machine shown in the drawings, in
which my improvements are contained, is adapted to form the type-bar by casting in the several matrices thin strips of type-metal bearing the printing-characters and veneering each of said strips as it is formed onto the edge of a previously-prepared hard body or slug. The improvements relate to the mechanism whereby the matrix-blocks and slugs are automatically moved into position near and parallel to each other, to themeans for inclosing the space between them, to the construction of the nozzle and its arrangement with respect to said inclosed space, to the means for ejecting from the mold the matrixblock and type-bar, and to the means for separating said matrix-block and type-bar, all of which will be hereinafter described, and definitely pointed out in theclaims.
In the drawings, Figure 1 is a plan view of my improved machine. Fig. 2 is a front elevation thereof. Fig. 3 is an enlarged detached view of two bevel-gears employed in the construction. Fig. 4 is a detached View of the mechanism for separating the matrix from the bar which has been cast therein. Fig. 5 is a vertical section on line 5 5 of Fig. 1. Fig. 6 is an under side view, on an enlarged scale, of the hopper or double reservoir hereinafter described. Fig. 7 is a partial vertical sectional view of said hopper on the line 7 7 of Fig. 1. Fig. 8 is an enlarged perspective view of the hopper with the upper portion broken away. Fig. 9 is a perspective View of one of the matrices and the slug upon the edge of which the linotype is to be cast and veneered, and this drawing shows the relative position of a matrix and type-plate when a linotype is about to be cast. Fig. 10 is a perspective view of the insideof one of the hopper-doors. Fig. 11 is an end view of a completed type-bar, and Fig. 12 is a vertical longitudinal section of the nozzle and lower part of the hopper.
Referring to the parts by letters, A represents the bed of the machine.
' The main driving-shaft Bis mounted in the brackets a a, which are attached to the bed, and the driving-wheel b is attached to the main shaft.
The melting-pot O is fixed in suitable relation to the other parts of the machine, and as a matter of convenience it lies mainly beneath and is secured to the bed-plate. A pump is provided for forcing the molten metal out of the melting-pot to and through the nozzle 0 The pump-cylinder c is located beneath the driving-shaft B, and the piston-rod 0 extends upward out of said cylinder, and it is provided with a slot 0 through which the main shaft B passes. Secured to the inner side of theplunger-rod above theslot 0 is a small projection 0 (on which preferably a frictionroller is mounted,) which is in contact with a cam 12, which is keyed to the main shaft. A spring a which is attached to the bracket a, bears upon the upper end of the piston-rod, thereby tending to force it downward.
The hopper D is rigidly secured to the bed A over the nozzle 0 It is provided with two compartments d d. The front compartment or reservoir is adapted to contain the slugs or metal plates from which the type-bars are formed in the manner to be presently described, and the rear compartment d is adapted to contain the matrix-blocks. reservoirs are separated by the partition d through which passes the shaft E, having the gear-wheel e keyed onto its outer end, said gear 6 being in mesh with a gear 19 on the main shaft B. Keyed to the shaft E on each side of the hopper are the cams e e, the purpose of which will be presently explained. Two vertically-sliding doors d d are set into the two sides of the hopper below the shaft These two E, and these doors are adapted to be moved downward against the bed-plate A by the pressure of the cams 6 upon lugs d, which project outward from the upper ends of the sliding doors 61 The doors are raised above the bed-plate by means of the springs d, which are attached to said doors and to the sides of the hopper. Two arms d d are pivoted to each of the doors d at a point (1 One of the arms extends rearward and the other forward from this pivotal point. These arms are pivoted at their opposite ends to levers d (1 said levers being pivoted to the base of the hopper at (1 The lower ends of these levers are pivoted to the links (1 which links are also pivotally connected with the two laterally-movingplates C1 d, which lie normally in recesses underneath the front and back walls of the hopper. The front plate 01 rests upon the bed, and the back plate (1 rests upon the thin sheet-metal plate M, which in turn rests upon the bed.
From the above-described description of the construction of the hopper and the parts connected therewith it will be understood that by revolving the shaft E the action of the cam e on the lug d will force the doors 61 downward. The downward movement of these doors causes the sliding plates (Z d to move toward each other into the reservoirs d d through the medium of the arms (1 levers 61 (l the links (Z and their pivotal connection with each other and the base of the hopper, as described. The perforated nozzle 0 protrudes through the bed of the machine directly beneath the partition 01 which separates the two reservoirs contained in said hopper, and said nozzle extends the entire distance between the two sides of the hopper. As shown in the drawings, the nozzle extends out beneath the right side of the hopper, although the part which so extends beyond the hopper is imperforate. This construction is preferred, so. that larger type-bars may be made in the same machine by substituting a larger hopper for that herein shown. The partition (1 does not touch the nozzle, but lies a short distance above it, and at a distance above the bed-plate equal to the thickness of one of the slugs M.
When the machineis in its normal position, the hopper contains a supply of slugs and matrix-blocks in the reservoirs d d, respectively. The lowest slug rests upon the bedplate between the laterally-moving plate 61 and the nozzle 0 while the lowest matrixblock will rest on the sheet-metal plate a between the laterally-moving plate (Z and the nozzle. The sheet-metal plate a is movable toward and from the nozzle. On its front edge is an upwardly and rearwardly turned knife-edge a, against which the matrix-block is pressed as it is forced forward by the laterally-moving plate (Z A spring a which lies between the hopper and an upwardlyturned arm a on the rear edge of said plate a draws said plate backward when it can.
and it engages with a rack 72, on a slide H,
which is adapted to move into the hopper D when the doors are raised, and to push out from said hopper the lowest matrix and the type-bar which has just been formed therefrom. This gear-segment is connected with the crank-shaft B by a connecting-rod f.
I will now proceed to describe the operation of the machine.
WVhen the machine is in its normal position, the piston 0 covers the opening through which the molten metal flows from the melting-pot to the pump-cylinder, as shown in Fig. 5. The melting-pot is heated byaburner c", which is supplied with gas by the pipe 0 When the driving-wheel b is turned, the gear 11 being in mesh with the gear 6, causes the shaft E to revolve, which, through the action of the cams e e, forces the doors d downward. At the same time the laterally-sliding plates 01 (Z are moved toward the nozzle.
A slug and a matrix-block being in their path are necessarily moved toward each other until they lie close and parallel with each other. The space between the slug, which constitutes the mold into which the molten metal is injected, is inclosed by the parts and in the manner as follows, to wit: The slug, in being moved as described, is forced .beneath the lower end of the partition (1 and said slug fits so snugly between the bed-plate and partition as to prevent the escape of the molten metal over or under it. The slugs are also of a length which is exactly equal to the dis tance between the two doors (P, so that when said doors are closed they prevent the escape of molten metal around the ends of said slugs. The front edge of the matrix-block engages with the knife-edge a on the sheetmetal plate a thereby causing said plate to slide forward until it strikes the nozzle and closes over a depression a in the bed A. The said matrix-block also engages with a horizontal knife-edge (Z which is on the lower edge of the partition 01 and with vertical knife-edges (l ,which are formed on the inner side of the sliding doors. (See Figs. 6 and 10.) These knife-edges a c1 and d d cut into the matrix-block and form a tight joint with it, whereby the escape of molten metal around said matrix-block is prevented. As shown in the drawings,-the nozzle 0 extends out of one side of the hopper, and when it does so extend a groove d" in the under side of the door d is formed, which groove fits closely upon the nozzle when the door is closed. It will be understood that there is now between the matrix-block and the slug a narrow inclosed space which serves as the IIO Lil
mold, and the nozzle projects into this space or mold through one side thereof, and it lies parallel to the proximate face of the matrix and slug. The matrix-depressions are in the edge of the matrix-block which faces the slug, and in that edge of the slug which faces the matrix-block there is a groove 772, into which the molten metal enters, and by means of which the strip on which the letters and characters are cast fastens itself to said slug. While the slugs and matrices are being moved into the relative positions described and the space between them is being closed in the manner also described, the cam 72 on the shaft B, by pressing against the friction-roller on projection 0 has raised the pump-piston above the inlet a and molten metal has flown through said inlet into the pump-cylinder. The continued revolution of the cam permits the spring a to act suddenly to force the piston down and thus force the molten metal through the nozzle 0 into the space between the slug and matrix, and this makes a cast of the letters and characters upon' the matrix, which cast is veneered onto the edge of the slug. The continued revolution of the cam 6- permits the springs 61 to raise the doors (Z and as these doors are raised the laterally-movin g plates 61 (Z are returned to their normal position. At this point in the operation of the machine the toothed portion of the bevel-wheel b meshes with the bevelgear f on the crank-shaft F and revolves said crank-shaft once. This, through the connecting-rod f, rocks the gear-segment G, thereby moving forward the slide H into the hopper, during which movement it comes in contact with the matrix-block and type-bar Which has just been completed and forces said type-bar and matrix-block out of the left-hand side of the hopper, and then said slide is drawn back out of the hopper to its normal position. The nozzle, which extends into the mold through the side thereof, forms, necessarily, a groove m in the newly-cast part m of the resulting type-bar. As the bar is ejected from the hopper by the slide H this grooved part thereof slides in contact with the nozzle, and by this movement the connection between the typebar and the metal remaining in perforations of the nozzle is clearly severed. Moreover, the groove m formed by the linotype, serves as a guide for the compositor who assembles the type-bars and renders it unlikely that any of said type-bars will be inverted. A
shaft I is mounted in the brackets to a and to it are secured, first, a gear 1', which is in mesh with the gear 6 on the main shaft, and, second, a cam 2", which is in contact with the lever J This lever is pivoted to the bed, its rear end being upheld by a spring J, and near its middle a bar j is attached at right angles to it and above an opening a through the bed-plate. lVhen the matrix-block and type-bar are pushed out of the mold, the typebar slides onto a shelf e Fig. 4, (which is a part of the bed-plate A,) and under a finger (612. The matrix-block'lies over a hole in the bed-plate and under the cross-barj of the lever J. Then the matrix-block and type-bar are entirely clear of the hopper and mold, the cam 71 presses the lever J down and the crossbar j strikes the matrix-block P and bends it down, breaking it loose from the type-bar. This completes one entire operation of the various parts of the machine, and these op,- erations are automatically repeated, with the result of producing type-bars so long as the reservoirs are supplied with matrix-blocks an d slugs.
Having described my invention, I claim 1. In a machine for making type-bars, the combination of a mold adapted to be opened at one end to permit the removal of the typebar cast therein, with a perforated nozzle which projects into said mold through one side thereof and forms a recess in one side only of the type-bar, substantially as and for the purpose specified.
