FEED MECHANISM.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed September 13, 1901, Serial No. 75,305. Renewed January 30, 1909. Serial No. 475,219.

To all whom it may concern:

a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Feed Mechanism, of which the following is a specification.

This invention relates to means for imparting an intermittent or step by step movement to a member, such, for instance, as a typebar blank, or a component member of a composite typebar during the progress of making the bar.

The present invention is adapted for imparting movements to a blank which is to be subjected to appropriate operations to convert the same into a finished article, and it embodies a mechanism for feeding variable distances a blank from which or on which types are to be made to bring successive portions of the blank into proper relation with the type-making mechanism. I

There is shown, described, and claimed in an application filed by me on August 22, 1901, Serial No. 72,884, a feeding mechanism for accomplishing a similar movement of a blank or member as the present invention is adapted to attain. The invention disclosed in that application embodies as an element an actuator for engaging with preformed shoulders in the side face of the blank, and which when rotated upon its aXis intermittently accomplishes a corresponding forward or feeding movement of the blank. There is also shown and described in that application a modified form of actuator in which a pretreatment of the surface of the blank is not necessary to enable the actuator to perform its function.

The invention set forth in the present application includes as a feature a form of actuator designed to likewise eiiect a feed movement of the blank without necessitating the previous formation of shoulders for engagement with the actuator; the actuator, constituting the feed element of the present invention, being adapted to simultaneously form shoulders and engage with the shoulders thus formed to impart a step bystep or feeding movement to the blank.

As in the invention disclosed in my com- I anion application, when the direction of feed movement is uniformly in one direction,

I will usually employ, in the present construction a feed element or actuator adapted to engage directly with the blank and by its movement serving to shift the latter forward step by step. If the present invention is applied to a typebar mechanism in which a succession of types is produced through the action of successively-selected and operated dies, this forward movement of the blank is advantageously controlled at each step by the respective selected dies, and since these dies represent the letters of the alphabet and other characters of composition of different widths, a mechanism embodying the present improvements will usually include means for imparting variable movements to the blank corresponding to the varying widths of the type-making dies or analogous instrumentalities successively brought into working position.

In the drawings accompanying this specification, Figure 1 is a side elevation of a mechanism embodying my present improve ments, and which is adapted to impart a step by step variable movement to a typebarblank, parts of the figure being broken away the better to show parts lying beyond. Fig. 2 is an end view of the mechanism looking from the right in Fig. 1. Fig. 3 is a horizontal cross-sectional view on the lane of the line 33, in Fig. 2, some of the details being omitted. Fig. 4 is a plan view of the actuator indicated and shown in the preceding figures, with certain of its associated parts, and illustrates the actuator in engagement with a blank, certain portions being shown in section. Fig. 5 is a side elevation of the parts shown in Fig. 4. Fig. 6 is a cross-sectional view on the plane of the line 66, in Fig. 4, looking in the direction of the arrow adjacent to that line. Fig. 7 is a perspective view of the actuator removed from its position relatively to its bearings and t0 the blank with which it is desi ned to engage; and Fig. 8 is a side view of a portion of a typebar-blank, showing the shouldenforming notches made in the side of the blank by the actuator.

Similar characters of reference designate corresponding parts in all-figures.

A typebar machine of simple construction is shown in the "drawings attached to this specification for the purpose of disclosing an embodiment of the present invention, whichlatter, it may be stated, includes as one of its features a combined shoulder-forming and shoulder-engaging instrumentality or blank actuator adapted to form shoulders in the side face of the blank and to effect through the positive engagement of the actuator with such shoulders the shifting of the blank. Combined with this shoulder-forming and shoulder-engaging instrumentality are means for imparting a discontinuous or interrupted motion to the actuator; this means preferably possessing a capacity of operation whereby the extent of the separate movements imparted to the blank, etc, are varied. It will e understood, however, that in so illustrating an application of the invention, I do not contemplate the limitation thereof to embodiment in the specific form of mechanism shown, but consider the invention in its broad aspect to be coextensive with the elemental organization above outlined; that is to say, as including any mechanism which embraces an actuator serving to simultaneously make shoulder-forming notches in a blank or other element, and to engage therewith to shift the blank combined with means for imparting a discontinuous motion to the actuator.

Referring now particularly to the specific construction of mechanism shown, there is embodied therein a plurality of type dies appropriate for producing a desired series of types on the edge of a blank, combined with means under the control of the several dies for shifting the blank along step by step and bringing consecutive portions of the edge thereof successively to the working point of the machine, at which point the dies selectively operate to produce the desired succession "of types and word-separating spaces.

The particular species of mechanism to which the present machine belongs is that wherein a rotatable die-carrieror plurality of the same is mounted upon a rotatable maincarrier or turret, which by its motion serves to convey the die-carriers past the working point, but normally in inoperative relation with a blank located thereat.

In the construction shown, a suitable supporting base-plate, designated in a general way by B, is provided, whereon the various operative members are mounted.

For the purpose of bringing a selected die to the working point and causing its operation thereat by a rollingmovement over the edge of the blank, there is provided suitable mechanism, under the control of the operator, for initiating, continuing, and ultimately arresting the rotary motion of the particular diecarrier shaft upon which the particular die-carrier upon which the particular die is mounted, as such carrier revolves about the axis of the turret.

Entering now upon a more Jar-ticular description of the various detaiis shown, the main-carrier or turret is designated in a general way by T, and embodies a shaft 2 :iounted in bearings provided in or supported on uprights 33 erected from the baseplate B. This shaft 2 is adapted to have a rotary motion in its bearings, and for its actuation a pulley 2 is shown attached thereto, which pulley may be driven by a belt from any suitable source of power (not shown). In this instance, two die-carriers 44 are shown attached to respective shafts 55, each mounted in bearings carried by arms 66, respectively, a pair for each shaft. These arms extend from the main shaft 2 of the turret, and are rigid therewith, thus causing, during the rotation of the turret, the revolution of the shafts about the axis of the former shaft.

During the rotary movement of the turret, the dies, designated in a general way without preference by D, upon each of the diecarriers 4-4, are inoperative to impress a properly located and supported blank; but when the rotation of a die-carrier is initiated, at the proper point in the path of orbital movement of the carrier, that die which is coordinated with such point will, when conveyed to the working point of the machine, roll over the edge of a blank located thereat, and form in or on such blank a type as the result of the rolling action to which the material of the blank is subjected.

For the purpose of initiating the rotation of each die-carrier or die-wheel 4, I have indicated in a conventional way the customary devices employed in mechanisms of this class, embodying a series of keys, designated a general way by K attached to corresponding latches L, suitably mounted in a latch-frame 7 erected upon the base-plate B. 'lwo series of keys and corresponding latches are herein shovm displaced axially of the turret, each latch L, when released, being thrown ii'iward toward the axis of the turret by a corresponding spring 8 attached to the latch and to a fixed portion of the latchframe.

It will be understood that the key and latch mechanism described and illustrated are merely typical of a more perfect construction, since the present illustrated mechanism is intended as a conventional representation only.

It will be noted that each spring 8 is arranged obliquely with reference to the axis of its corresponding latch, and that each latch is provided with a notch 8 adapted to cooperate with the edge of the opening in the latch-frame through which the latch moves. lfuthermore, each series of latches in the present organization is shown as being made up of nine separate members disposed at different points concentrically about the turret axis, although, of course, a greater or lessernumber may be used, depending upon the number of separate amounts ofrotative movements which it is designed shall be impartable to the shafts 55 and their attached die-carriers.

In Fig. 2, the series of latches are severally represented in their inoperative or retracted position. lfhen it is desired to set a latch, and hence effect the rotative movement of a die-wheel or carrier, and the consequent operative movement of the selective die, the corresponding key is, in the simple construction illustrated, urged laterally to disengage its notch 8 from the edge of the latch-frain e, whereupon the attached spring 8 projects the latch inward until its movement is arrested. by the contact of a shoulder 1 on the latch with the latch-frame.

Adapted to cooperate with the latch when projected is a starting-arm 9, one for each shaft, and to which it is attached, the starting-arms for the two shafts being arranged in the planes of the two series of latches L. When the turret is rotating and the latches are withdrawn, no cooperation of a latch with its starting-arm takes place; but when a latch is set, the starting-arm located in the plane of that series of latches of which the set latch forms a member upon coming into contact therewith causes the angular movement of the shaft to which it is attached, initiating thus the rotation of the latter. According to the present construction, which, it will be understood, is illustrative merely of one construction for accomplishing the same result this rotation is continued as the result of the operation of the following mechanism, it being premised that the mechanism for each shaft is the same.

Surrounding each shaft 5 and com elled to rotate therewith, but shiftable aXia y of the shaft (as by a key and slot construction), is a corresponding sleeve 10, carry'mg a pinion. 11 with which there is also fixedly related a cam-finger or cam-arm 12, here shown to be of a resilient nature. During the normal rotation of the turret,-that is, with the dies inoperative to impress a blank located at the working point of the niachine,-the camarm 12 occupies a position in which it is free from engagement with a corresponding cam 13. fhenever the shaft is started rotating, however, as a result of the cooperation of its starting arm with a projected latch, the cam arm is shifted into a position in which it 00- operates with such cam 13. lhe inclination. of the surface of this cam is such that during the further cooperation of the starting-arm and the projected latch, it operates through the contact of the cam-arm therewith to shift the sleeve 10 longitudinally of the shaft 5 and bring the pinion 11 thereon into engagement with a fixed driving-gear 14, here shown as an internal gear. Upon such engagement taking place, the sleeve and the shaft upon whichcit is mounted continue their rotation during the rotary movement of the turret.

Before, however, the actuated starting-arm 9 has left the projected latch, a resetting socket 9 at the end of the former, will have operated to thrust the latch outward, thus permitting the rengagement of the notch 8 of the latch with the edge of the opening in the latch-frame. During the further rotation of the turret, the independent rotation of the shaft 5 and its connected parts continues until after the die has passed the working point, whereupon a cam-arm 15 attached to the rotating shaft will be brought into engagement with a cam 16 having a cam face oppositely-inclined to the cam-face of the cam 13 and which operates to cause the shifting of the sleeve 10 in the opposite direc tion, and consequently the disengagement of the pinion 11 from the driving gear 14, With this release of the pinion 1 1 the positive rotation of the shaft 5 about its own aXis ceases, and to insure correct positioning of such shaft and consequently of the die-carrier attached thereto, (which, it will be understood, is essential in order that the proper amount of rotative movement of the diecarrier may take place at the next die selection,) there may be provided a suitable detent device for stopping the movement of the carrier in a definite position upon the release of its pinion 11. This device, as herein shown, comprises a spring-pressed plunger 17 suitably mounted to cooperate with a flattened portion of the shaft, and operating as a brake to arrest the rotation of the shaft in a position in which the plunger is in contact with such flattened portion.

The present mechanism embraces means for automatically feeding a blank or other member through the instrumentality of a selected and rotating die-carrier during the revolution of the latter around the axis of the turret shaft, the feeding of such member being under the control of parts coordinated with the selected die thereon. Entering upon a description. in detail of the various features of this portion of the mechanism, each die-carrier is provided with a number of faces coordinated with the dies on the carrier and each adapted during the movement of the die to which it is related to the working point for effecting the movement through intervening mechanism of the element or actuator hereinbefore referred to. These feedfaces, designated by 18 without preference, are herein shown as shoulders formed by the end walls of recesses which. are conveniently and as shown herein made in the radial face of each pinion 11; and to enable such feedfaces to regulate the variable movements of the blank, they are shown of diiferent radial depths, since, when so constructed, they are adapted to effect the described movements of the blank.

As an engaging pinion 11 rolls around the surface of the driving-gear, a feed-face 18,

corresponding to that die which will ultimately roll over the blank at the working point, is brought into engagement with a pin 19 extending from an arm 20 pivoted to a rock-lever 20 fastened to a rock-shaft 21. The normal position of this rock-shaft is de termined by a spring 2]., which tends to turn the shaft and bring a stop-arm 22 thereon. into contact with a stop-pin 23 projecting from a fixed portion of the machine. As the die-carrier continues its orbital movement with the pin 19 in engagement with the feed-face, the pin is carried outward; and through the described connection the rockshaft is rocked in. its bearings until, as the die-carrier continues its movement, the arm 20 is deflected from its position, and the die-carrier leaves the pin 19. In order to insure the correct and normal positioning of the arm 20 with the pin 19 disposed in the path of a selected and rotating die-carrier, I have shown a spring-arm 2% extending from the arm and located between stops 2525. As a result of the action of spring 21 and the spring-arm 24, the rock-shaft 21 and the parts mounted thereon are caused to assume their proper relative position to cooperate with a feed-face on a die-carrier when the latter is next set in rotation.

The intermittent angular movement of the rock-shaft 21 is transmitted to a shaft 26 mounted in. hearings in the body of the internal gear 14, and in the latch-frame 7, the transmitting mechanism embodying a link 27 pivoted at one end to an arm 28 extending from the shaft 21, and at the other end to a pawl-carrier 29, supporting a spring-pressed pawl 30 engaging with a ratchet-wheel 31 secured to the shaft 26. The arm 28 is shown A as extended forming a hand-lever (see 32) to enable the shaft 26 to be rocked manually, when desired. From this shaft 26 motion is transmitted to the feed element or actuator already referrred to.

As illustrated in the drawings attached to the present specification, the member adapted to be fed under the dies and on which the latter operate to form a determinate succession of types as the dies roll in turn over its edge, is shown as a blank whose type-forming portion or edge is integral with the body of the blank. It will be understood, however, that the invention is applicable to the feed ing of other memoers, such, for instance, as a typebar body or type-carrier.

in the mechanism set forth in my first hereinbefore mentioned application, the blank is fed under the dies in the plane of rotation of the die-carriers and this is the case in the present illustrated embodimeir of the invention. It will be understood in this case, however, as in the former, that this specified relation is chosen merely for illustrative purposes, and in no wise constitutes a limitation of the present invention. The blank, furthermore, in my companion application, is represented as a short length blank; that is, one Whose length is approximately equal to the length of the line of types to be made and while, of course, the present construction is suited to the feeding of such a form of blank, I have illustrated the blank herein as being the form of a continuous ribbon or strip, designated in a general way by C, and

conveniently fed from a reel VJ, upon which the blank is coiled around a center U having a notch it with which the inner end of the blank is engaged.

The blank is adapted to be fed through a slot formed. between side-pieces or uprights 33, 34, serving to support and maintain the blank in a fixed position during the rolling movements of the dies. In order that that blank may lead freely through the slot between the uprights, I preferably so mount the reel W as to enable it to shift its position as the blank is withdrawn from the supply coil, and the diameter of the latter diminishes with the consumption of the blank.

As constructed in the present instance, the reel W is mounted upon a swinging arm X pivoted in any desired way, for instance, by a pin X, to the base late B of the machine, the reel and the coi being preferably constantly urged into a position, as by a spring Y, in which the blank, immediately prior to its separation from the coil, impinges against a stop-roller 1* mounted upon a fixed portion of the base plate, thus enabling the blank, after passing through a pair of guide-rollers s, s, to enter the slot between the uprights 33, 34, the alinement of the blank with such slot being assured by the position of the rollers s, 8. Obviously the separate typebar-lengths may be severed from the ribbon-blank by any suitable means subsequent to the formation of the types on the edge of the blank.

I prefer to have the actuator or that element whose movement serves to shift the blank step by step through the supporting slot between the uprights 33, 34, engage .directly with the face of the blank, since such a construction is convenient and necessitates but few parts. The actuator designated in a general way by E, and constituting a feature of the present invention, is in the nature of a combined shoulder-forming and shoulder-engaging actuator, the operation of which serves to simultaneously form shoulders in the face of the blank and engage with the shoulders so formed. That is to say, during the movement of the actuator, it performs two functions, to wit: the notching of the face of the blank to form shoulders therein, and by engagement with such shoulders to cause the feeding of the blank forward. This actuato may conveniently be for-med as a single integral member, and, as shown in the present case, it is a rotatable member having a helical Working face or thread upon its periphery whose form is that of the so- 1 sponding to that adjacent to the cusp of a called ratchet thread. By channeling or fiuting the periphery of the actuator to an extent sufficient to intersect adjacent portions of the thread or threads, teeth are formed thereon, which, when the actuator is :rotated, serve to notch the face of the blank (see the notch c, Fig. 8) and form shoulders therein,

which shoulders, as the blank moves forward, are engaged by the opposite end of the actuator, and when the latter is rotated cause the advance of the blank. The actuator will be provided with a suitable shaft 36, mounted in proper bearings, such as 36, 36. The shaft 36 may be conveniently driven from the shaft 26 by means of bevel gears, such, for instance, as 37 and 38.

A machine organized and constructed, as illustrated and described, operates substantially in the following manner :Assuming a key K to have been actuated andthe attached latch L to be in its innermost position (the turret being in rotation), when the starting-arm 9, which is located in the plane of that series of latches of which the proj ected latch forms a member, comes in contact with the latch, the rotation of the shaft- 5 will commence, the sleeve 10 surrounding such shaft rotating with it. Some time before the starting-arm leaves the latch, the cam-arm 12 will be brought into engagement with the cam surface of the cam 13, and the pinion 11 will be shifted into engagement with the driving gear 1 1, as already described. The shaft 5 will now continue its rotation, but before the starting-arm disengages itself from the latch, the latch will have been thrust inward, in the described manner, to cause the rengagement of the notch Z with the latch frame 7 resulting, in consequence, in the holding of the latch in its outward or normal position. Before the die, to which the projected latch is related, reaches the working point, the feed-face 18 on the radial face of the rotating and revolving pinion 11 will be brought into engagement with the pin 19, and the rock-shaft 21 will be rocked in its bearings, causing, it will be readily understood from the foregoing description, the angular movement of the shaft 26, and throughv the intervening mechanism the partial rotation of the actuator E. The teeth on this actuator operate to notch the blank, and the latter will, simultaneously, be shifted lengthwise of the slot between the supporting uprights 33 34 into a position in which the proper portion of the edge of the blank is brought under the die, the extent of this movement being determined by the throw of the rock-lever 20, which in turn is determined, as already described, by the radial depth of the recess in the face of the pinion. As the given die nears its working position, it will approach the edge of the blank along a path correcycloid, and as it leaves the blank after rolling over the same, it will describe the second or complementary branch of the cycloidalcurve adjacent to such cusp. At the same time, and subsequent to the disengagement of the die from the blank, the cam-arm 15 will, byreason of the continued movement of the parts, be brought into engagement with the cam 16, whereupon the sleeve 10, and hence the pinion 11 attached thereto, will be shifted in the opposite direction and the latter disengaged fromthe driving gear 14. The rotary movement of the shaft 5 about its axis is now free to be checked, a result which follows from the performance by the plunger 17 of its function as a precision brake, ultimately locating the shaft in the same normal rotarial position. Such substantially is the operation of the various features embodied in the illustrated mechanism, the action being repeated at each actuation of a key, while the extent to which the blank is fed varies with the particular die chosen, in the event that this is desired, and there is an existing variation in the depth of the feed recesses, as described.

In using the term blank, I wish to include any and all elements analogous thereto as adverted to in the foregoing.
