I MECHANISM FOR MAKING, FINISHING, AND PACKING TYPE.

SPECIFICATION forming part of Letters Patent No. 239,942, dated April 12, 1881. Application filed August 13, 1880. (No model.) I

To all whom it may concern:

Be it known that 1, PETER DILLON, of Sherbrooke, Province of Quebec, Canada, have invented an Improvement in Mechanism for Making, Finishing, and PackingType, of which the following description, in connection with the accompanying drawings, is a specification.

Thisinvention relates to mechanism for making or casting type, finishing the same, and placing the finished type in suitable tubes or packages ready for automatic distribution therefrom by machinery, such as type-setting machines.

In this my invention the molds, grooves, or spaces in the mold-blocks are filled with molten type-metal from a molten-metal holder by means of a force-pump and pipes or tubes in the usual manner. carried by an intermittingly-operated wheel or mold-carrier, and opposite the rear ends of the mold-blocks, in which the molten type-metal is forced or charged, is the matrix, usually of copper, and provided at its face with afac-sim ile of the letters or characters to be produced upon the type, the said matrix being preferably dovetailed upon its carrier-slide, so as to be readily changed for one having a different letter or character. (lo-operating with each mold-block are movable nick-formers, herein shown as composed of needles connected with radially-movable slides, the said needles remaining in the mold-spaces, and extended across one side thereof, until the type are to be ejected therefrom, as hereinafter described.

The type-metal having been run into the molds, the leading device is lifted, leaving the runners extendinglaterally out from the molds, and as the mold-carrier is turned these runnersare brought in contact with a suitable blade or cutter, that cuts them ofi' close tothe mold-block, leaving the type of proper length.

Further rotation of the mold-carrier places the type in the mold-blocks opposite ejectors that are moved forward against the ends of the type and eject them from the moldblocks, and as the type are forced longitudinally out from the mold-spaces of the moldblocks, they are forced through a trimming device, which cuts off all fins or sharp corners and planes and smooths the sides of the type uniformly. The ejectors leavethe type under The mold-blocks are plungers, that in their descent meetthe upper sides of the type and deliver them into open tubes, asuitable movable rest in the tubes descendin g gradually as each type is forced into the tube. These tubes properly filled with type, all arranged in the same'order, and allof the same kind and size, may be transferred to a type-setting machine such as describe in United States Patent No. 225,468, dated March 16, 1880, where the type may be distg ibuted mechanically. I

My invention consists in certain combinationsof mechanism hereinafter particularly set forth for making, finishing, and packing the type in tubes, and also in the method or process herein described, by which I am enabled to cast and automatically finish the type and place them in tubes.

Figure 1 represents, in side elevation and partial section, sufficient of a type making and finishing machine to illustrate my invention, a part of the frame-work being broken away to the better show the working parts; Fig. {5, a vertical section on the line a: m, Fig. 1, lookin g in the direction of the arrow; Fig. 3, a partial vertical section on the line 3 3 Fig. 1, the

mold-carrier being partially in section Fig. 4, a detail illustrating the leading device in advance of the molds, to lead themolten metal from the usual tube into'the mold; Fig. 5, an

elevation of the packing-tube, one side being broken out 5 Fig. 6, a top view of the packingtube and the rest or movable type-support within it; Fig. 7, a partial side elevation of the casting-machine, with the molten-metal-containing apparatus shown-at the right in position to feed the leading device; Fig. 8, a perspective view of the trimming-die located at the rear of the mold-carrier.

.The frame-work a of the machine will be of proper shape to sustain the working parts.

The main shaft 6, driven in any usual way, has upon it a-carn, c, suitably grooved tomove the ejector and leading device at the proper time. I

' The leading device 01, made as a block with one or more grooves, all", is carried by the lever d, which is turned to raise and lowerthe leading device by means, ashereinfshown,

of a link, d connected with arm. d of the rock-shaft at, having secured to it an arm, cl,

having a pin or stud, d, that is extended through the upper end of the lever al into the groove of the cam 0. The leading device, when depressed, as in Fig. 1, rests upon the bed 0, closing one side of the groove or grooves 01", into which the molten type-metal is forced from the pipe 6 by means of a force-pump, P, in the usual manner. This pump, being commonly so used, is not herein. specifically described. The molten metal is forced into the grooves of the leading device, and into the grooves or molds in the mold-block f in line with-them, and against the movable matrix f, it being made of copper, and having cut into it the'letter or character it is desired should be produced upon the type. This matrix, guided and fitted in the frame-work to slide therein toward and from the mold-carrier f ,,is operated, by reason of its connection with the arm f of the the rock-shaft 61 before described, by link 20. The matrix is moved backward, away from the mold-block as soon as the typemetal has assumed definite shape or taken the form to be imparted to it by the matrix; and just as the matrix is withdrawn away from the mold-block in the direction of the length of the type the leading device is lifted from the bed 0, uncovering the runner 22, leaving the same projecting laterally from the mold and the type t. (See Fig. 4.)

The shaft bhas at its end a crank-pin, g, that engages the egg-shaped projections g radiating, as shown in Fig. 3, from the center of the mold-carrier f which is supported by the shaft f and turns the said mold-carrier one step at each rotation of the shaft 1), the said crank-pin traveling in and outbetween the said projections. This shaft f 4 has uponita cam, it, having a number of projections, that atthe proper time strikethe yoke 4 at the top of the plungers, 2', depressing the said plungers to cause themto strike the types 25 under them and force the said types down into the tubes k. These plungers are raised automatically by springs i on their shanks. The grooves or molds to shape the type t are formed in suitable mold-blocks f,

attached to the mold-carrier, as herein shown, by screws l there being a greater or less number of such mold-blocks, containing one or more grooves or molds attached to the moldcarrier, the mold-carrier forming one side of each groove or mold.

In the front face of the mold-carrier I have arranged a series of radial slides, m, each having one or more nick-formers, m (shown as round steel wires or needles,) which, when the slides are moved outward, are made to extend through the molds at one side. These nick-formers are projected into the grooves or molds in the mold-blocks, as shown at Fig. 2, at the time the type-metal is being forced therein, and they are completely withdrawn from the said molds just before the type are to be ejected, which takes place about as the mold-blocks arrive at their lowest position in the rotation of the mold=carrier. Each slide has a pin or roller-stud fitted into the cam-groove m of the stationary cam-disk mi. (See Fig. 2.)

The ejectors 0 are steel rods, just the shape in cross-section of the molds, and are adj ustably connected by a washer, 0 and screw 0 with a carriage, 0 fitted in suitable guideways in the frame-work a. The ejectors are long enough to pass entirely through the molds and trimming devicep, made as blocks having passages (see Fig. 8) in area the same as the molds,.so that as the ejectors eject the type from the molds they force them longitudinally through the openings in the trimming devices and trim off or plane off from the type any fins or projections thatmight be left between the mold and matrix. The type having been passed through the trimming device are left under the plungers, as before described. As the mold-carrier is rotated or moved, as before described, and between the time that the leading device is lifted from a runner and that mold-block reaches the ejector the said runner 22 is brought against the cutter r and is cut off smooth with the end of the mold-block, thus defining thelen gth of the type and smoothing or squaring its lower end. The nickin g devices remain in contact with the type until the lower ends of the type are cut off, and consequentl y the type cannot slip or move longitudinally during such operation.

The carriage 0 is connected by link 8 with the lower end of the lever d", pivoted at 8.

The rocker-arm d ,by the arm a, is made available to move forward the molten-metal holderp! and place its tube 0 against the leading device preparatory to pumping type-metal into the grooves 01", and this same shaft may also be used to operate the usualpump, as in Fig. 7.

Instead of mounting the mold-blocks upon a rotating carrier, it is obvious that I might mount them upon alongitudinally-movable carriage or bed Without departing from my invention; but I prefer the plan shown.

I have shown each mold-block as provided with two molds, to make two type at the same time, and have employed herein two ejectors; but it is obvious that I might use one or more molds in each block and ejectors to correspond with the number of molds in a block.

I consider that I can by this machine make type cheaper than they can be distributed after having been set, and consequently the type once used may, if desired, be remelted, thus avoiding distributing; or they may be sold or used over again, if desired.

I claim 1. In a type-making machine, a vibrating leading device and a matrix, in combination with a series of mold-blocks, a mold-carrier, and means to move the mold-carrier intermittingly, as specified;

2. In a type-makin g machine, a series of intermittently-moved mold-blocks, in combination with a matrix reciprocated in the direction of the length of the axis of said moldscribed.

3. In a type-making machine, the movable mold-blocks and carrier, and its nicking de-' vices alternately projected within and drawn from the mold, combined with the matrix and leading device, substantially as described.

4. In a type-m aking machine, theleadin g device, mold-blocks, mold-carrier, and matrix, combined with the cutter to cut off the runners, determine the length of the type, and smooth their lower ends, substantially as set forth.

5. In a type-makin g machine, the mold-blocks, matrix, and movable mold-carrier, combined with the cutter to cut off the runners, and with the ejectors to eject the type from the molds, as set forth.

6. The movable mold-carrier and nicking devices to hold the type thereon against longitudinal displacement, combined with the cutter to cut off the runners and square the lower ends of the type, substantially as described.

7. The mold-carrier, mold-blocks, and ejectors, combined with the trimming device, into which the type are forced and trimmed or planed smooth.

- 8. The combination of the intermittentlymovable mold-carrier and its mold-blocks with ejectors 0,1)il1Hg6ISi, and means to operate the same, substantially as described.

9. In a type making machine, an intermitti n glyrotatin g mold-carrier, mold-blocks, leading device, and matrix, combined with the cutter to trim oft the runner, ejector to remove the type from the mold, and trimming device, through which the type is forced and trimmed automatically, substantially as described.

10. In a type-making machine, the combination of an intermittently-movable mold-carrier, a series of mold-blocks thereupon,in which the type is cast, a matrix adapted to be moved up to the end of each mold as the type is being cast therein, mechanism for cutting otf the runner from the type while yet in the mold, and ejectors for expelling the type from the mold through trimming mechanism or dies, to remove the fins and smooth the type, all as set forth. 1

In testimony whereof Ihave signed myname to this specification in the presence of two subscribing witnesses.
