MATRIX-MAKING IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 479,77 3, dated. July 26, 1892. Application filed March 20, 1888. Serial No. 267,796. (No model.)

T0 all whom t may concern:

Be it known that I, GEORGE A. GooDsoN, a citizen of Canada, and a resident of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Matrix-Making Machines, of which the following is a specification, reference being had to the accompanying drawings. n

My invention relates to matrix-making machines, and is in the nature of an improvement on the machines set forth in my patents, Nos. 414,399 and 414,400, dated November 5,

1889, andin my former applicatiomtiled May 31, 1887, underSerial No. 239,735.

Theimprovements herein set forth are comprised more particularly in the feed mechanism and the electric connections for the same,A

In the drawings like notations refer to like parts throughout.

Figure I is a plan of my machine with the die-impressing mechanism and part of the die-carriage seat removed. Fig. II is a view of the machine, partly in longitudinal section and partly in side elevation. Fig. III is a plan, on an enlarged scale, of the escapement and its connected mechanism in working position, part of the machine being broken away. Fig. IV is a section on the lines XX of Fig. III. Fig. Vis a detail showing anv armature-lever. Fig. VI is a detail in section showing the escapement-lever and ratchetwheel detached. Fig. VII is a detail of a part of the matrix-material carriage in longitudinal section showing the mechanism for effecting the lateral movement of the same for spacing between the lines. Fig. VIII 1s an under side view of the escapement-lever and with key-seats having contact-points adjacent y to the same, 3 the combined die-alignment bar and hand-key, 4the die-carriage on one Vend of said bar, 5 the hand-key with contactpoint on the other end of said bar, 6 the typedies classified according to the units of space required, 7 the contact-points adjacent to the key-seats on the character-board, 8 the diecarriage seat provided with a tapering hole a in line with the common centeror printingpoint, 9 the matrix-material carriage, and 10 the rack-bar attached to said carriage, all suhstantialiy the same as in my former applications.

I will now describe my improvements.

11 and 12 are a pair of motor-springs attached at one end to the bed-plate or other xedsupport and at the other to the matrixmaterial carriage. Weights can be used.

13 is vertical shaft rigidly secured to the bed in proximity to the rack 10.

14 is a pinion loosely mounted on this shaft for engagement with said rack and is provided with an extended hub 15, reaching to the level of the top of the shaft.

16 is a ratchet-wheel rigidly secured to the hub or sleeve l5.

17 is an armature-lever pivoted at one end to a suitable support, as the post h, secured to the bed-plate, and is provided at its other end with the extensions b and c at right angles to the armature portion. The arms b and c lie in a line across the center of the ratchet- Wheel 16, thev arm b extending beyond the periphery of the wheel and the arm c stopping near the edge of the same. The part c is provided at its outer end with an arc-shaped slot d. 18 is an electro-magnet for operating said armature-lever 17. To the under side of the outer end of the lever-arm b is attached a pawl 19, which when said lever is in its normal position engages and locks the ratchetwheel 16, preventing its movement by the motor-springs 11 and 12. To the lever 17, preferably near its outer end, is pivoted a stop-lever 20, which is provided with a projecting-lug e, Working in the slot (l in the lever-arm c. To the under side of the stople ver 2O is attached a pawl 21 `in proper position to be engaged by the ratchet-wheel16- The lever 2O extends outward a considerable distance beyond the periphery of the ratchetwheel and its outer portion is curved or inclined backward, andon its inner face it is pro vided with a series of step-like shoulders or offsetsf. The tension-springslland12,acting through the rack 10 and pinion 14, give the ratchet-wheel 16 a tendency to revolve, and said Wheel is normally held from such revolution by the pawl l?) on lever-arm b. V'Vhen the armature-lever 17 is drawn to the magnet 18, the paWl 19 Will release the ratchet-Wheel 16 and the paWl 21 Will be brought into engagement therewith. The tension of the springs will then cause the Wheel 1G to revolve, carrying the stop-lever with it until the said lever is stopped by the pin e coming into contact with the end of slot d or byother means, as will be hereinafter described.

22 is a retraction-spring secured to the lever 2O and to so me suitable base of resistance, as the post 23, for retracting the lever to its limit in the slot d.

24E is a retraction-sprin g attached to the armature-lever 17 at one end and to a suitable resistance, as the post 23, at the other.

S', S2, S2, S4, S5, and SG are a series of stops for engagement with one or anotherof the respective shouldersf on the stop-lever 20, and limiting the movement of the ratchet-wheel 16, and consequently the matrix-material carriage 9. (')f these stops S6 is stationary, and all the others are movable. The movable stops are mounted in suitable seats and guides iixed to or formed integral with the bed-plate, as the rigid bar 25.

M', M2, M2, M4, and M5 are a series of magnets having` armature-levers N', N2, N2, N4, and N5, respectively, for operating said movable stops. Each armature-lever is pivoted intermediate its extremities to a suitable support, as a post 2G, fixed to the bed-plate, and has one end attached to one of the movable stops.

R' R2, dsc., are a series of retraction-springs,

' attached at one end each to its respective armature-lever and at the other to a suitable base of resistance, as the bed-plate, for retracting the armatures fromtheir lnagnets and holding the stops normally out of the path of the stop-lever 20.

The type-dies are classified according to the units oi' space required. The characters on the character-board or index-seat correspond to the type-dies in the die-carriage and the contact-points adjacent to the key-seats are classified into similar groups, according to the u nits of space required, as in my former machines.

A local electric circuit through the handkey 5 and the magnet 1.8, which branches from the different groups of contacts on the character-board through the corresponding magnets l\' M2, duc., serves to unlock the escapement and operate the movable stops. Of the Wires constituting this circuit, A is the common outgoing Wire from a source of electricity (not shown) and Bis the common return-Wire to the same. The Wire A is connected to the bed-plate 1, and from the bed-plate the current passes to the alignment-bar 3 and the contact-point on the hand-key 5. There are as many branch Wires from the characterboard as there are classes of characters.

A' is the branch from the one-unit group to the magnet M', A2 the branch from the tWounit group to magnet M2, A2 from three-unit group to the magnet M3, A4 from four-unit group to magnet M4, A5-from tive-unit group to the magnet M5, and A6 from the six-unit group to the magnet 18. From the respective magnets M', M2, M2, M4, and M5, return branch Wires B', B2, B2, B4, and B5 extend to the magnet 18 and a common return branch B6 extends from the magnet 18 to the main return- Wire B. It Will be thus seen that the magnet 18 is on all the branches and that the machine is constructed for a variable feed of from one to six units.

27 is ashaft journaled on the matrix-cariage and provided with a pair of feed-rollers 28, rigidly attached thereto on its opposite ends, which engage and feed the matrix material laterally to give space between the lines. 29 is a ratchet-Wheel rigidly secured to this shaft 27. 30 is a paWl-lever loosely mounted on said shaft, and 31 is a pawl secured to said lever in proper position to engage said ratchet-Wheel.

32 is a cam-track secured to the bed-plate. One end is pivoted to the frame by pivot-pin 33, while the other is secured by a set-screw 34%, Working through a slot g. A cam-finger 34 is pivotally attached at one end to the pawl-lever 30 and has its free end resting on the track 32. As the carriage is Withdrawn to start a new line the cam-finger will raise the lever 30, and the paWl 31, engaging the ratchet'wheel 29, will turn the shaft 27 and feed the matrix material laterally the proper 'distance to form the space between the lines.

The slot g in the end of the cam-track affords a means of varying the inclination of the track, and consequently the distance between the lines, at Will.

35 is a rack attached to the end of the matrix-carriage adjacent to the character-board, and 36 and 37 is a graduated indicator operated by said rack for constantly indicating to the eye of the operator the distance fromthe end of the line.

38 is a cap-plate directly over the die-carriage seat provided With a hole in line with the common center or printing-point. On this cap-plate, as a seat, is located a device for depressing the die when at the common center and devices for controlling and actuating the same.

The die-depressing device and its operating and controlling mechanism here shown are the same as is fully set forth and broadly claimed in Letters Patent of the United IOO IOS..

IIO

States No. 414,400, dated November 5, 1889. While these parts are here shown andare those I prefer to employ, their particular construction is not herein claimed; nor is it essential to my present invention, as other equivalent devices might bel employed. It is herein shown to disclose the particular relation of this special form of electric die-depressing mechanism to the particular form of feed mechanism set forth in this application. Of this mechanism 39 is the supporting-standard secured to the cap-plate; 40, the plunger, working through the hole in the cap-plate 38 and held in a guide 41, attached to standard 39; 42, the toggle-lever, having one end attached to a base of resistance, as the rod 43, fixed in said standard, and having its other end attached to the' plunger 40.

44 is the supporting-plate attached to the cap-plate 38 and the standard 39.

45 is the solenoid having a hollow axis mounted on the supports 44 and 39.

46 is its movable core coupled to a source of power and constantly reciprocating. 47 is the independent movable armature having one end attached to the toggle-lever and the other supported within the field of the core 46.

48 is a constantly-running crank-shaft. 50 is a connecting-rod from the crank 49 on said shaft to said core 46.

51 is a driving-pulley, and 52 is a iiy-wheel, on the shaft 48.

53 is a retraction-spring attached to standard 39 and the toggle-lever 42.

54 is the electro-magnet for closing contacts of circuit-breaker. 55 is its pivoted armature having a projection extending into the path of the toggle-lever. 56 is a piece of hard rubber on armature end of said lever 55; 57, a contact-strip in the end of the rubber block; 58, a contact-strip normally 'in contact with 57 at one end and having its other end attached to the binding-post 59. These parts 55, 57, and 58 constitute a circuit-breaker operated by the toggle-lever 42. The contacts 57 and 58 when separated are brought into contact with each other by the magnet 54 and its armature 55.

The operation of the die-depression device is as follows: When a currentis passed through solenoid 45, the movable core 46 and armature 47 will be magnetized, and upon the core 46 approaching armature 47 the two parts Will adhere and be reciprocated together, thereby operating the toggle-lever 42 and depressing the plunger 40. As the toggle-lever is operated it will strike the projection of armaturelever 55 and separate the contacts 57 and 58, thereby breaking the circuit through the solenoid 45, so that the core 46 and armature 47 will be demagnetized and the armature released.

The electric connections for this die-depressing mechanism are as follows: A contact 60 is mounted on a piece of insulating material, as the hard-rubber block 61, secured to the bed-plate 1, adjacent to a part of the arma- `tact 62 are normally apart.

ture-lever 17 in position to be in contact with the armature when retracted to its limit by the spring 24. A similar contact 62 is mounted on a similar piece of insulating material 63, secured to the bed-plate in the proper position to be in contact with said armature (as the part 6,) when drawn to the magnet 18. The wholebed-plate of the machineis charged from the wire A. A wire C extends from the contact 60 to the magnet 54, and a return-wire C leads back to the source through the common return-wire B of the index or stop-magnet circuit. A wire D leads from the contact 62 to the solenoid 45, and a return-wire D leads from said magnet to thev bindingpost 59 through the circuit-breaker contacts 57 and 58, and thenceto the source through the return-Wire B of the index or stop-magnet circuit.

The operation is as follows:` The index or stop-magnet circuits are all open, as hereinbefore stated, at the index-plate. The armature-lever 17 and the contact 60 are normally together, and therefore the circuit C C through the magnet 54 is a normally-closed circuit, holding up the pivoted lever 55 and keeping together the contacts 57 and 58. The armature 17 -(part h, as shown) and the con- Hence the circuit D D', through the solenoid 45 and the circuit-breaker contacts 57 and 58, is normally open at the escapement. p Now when the hand-key 5 is depressed into the key-seat to' select any desired character` an index-circuit is closed through one or another of the stop-magnets, according to the space-group to which the character belongs, and through the magnet 18. The first effect of this is to un- IOC lock the escapement and throw up the proper corresponding stop and allowing the matrixcarriageto move the requisite distance, and the second effect is to bring together the armature-lever 17 and the contact 62, closing the circuit D D', through the magnet 45 and the circuit-breaker contacts 57 and 58, thus actuating the die-depressing device. The circuit D D remains closed only until the togglelever strikes the pivoted armature-lever 55. As soon as this occurs the contacts 57 and 58 are separated, breaking the circuit D D at that point. As soon as the hand-key is withdrawn from the key-seat on the index-plate, opening the circuit through the escapementmagnet 18, the circuit C C will be again closed,through the magnet 54, and all the connections will be in their normal condition, as hereinbefore stated. Inasmuch as the movable stops are all out of the Way, no magnet is required for the six-unit stop. On selecting such a character the stop-lever simply moves to its limit against the stationary stop. Veights may be used instead of the motorsprings for moving the Ymatrix-material carriage. It is only essential to keep the carriage under a constant pull or push of such a yielding character toV allow thecarriage to be stopped without injury to the mechanism.
