Fig. 9 shows the cylinder for feeding the for the repeated letter body and a series of successively used controller strips for addresses for recurrently printing the same letter with successive different names and addresses;

Fig. 10 is a fragmentary showing of the address strip; and

Fig. 11 is a view the left.

Referring now by way embodiment of the invention, vexemplarily illustrated in the accompanying drawings, the frame of a typewriter machine is shown at 1 and the key fragmentarily and somewhat diagrammatically at 2', but it will be understood that these mechanisms may be of any usual or suitable form. The automatic controllin mechanism i-s contained i a casing 3, the`\ eet 4 of the typewriter resting in supports or receptacles 5 on the top of the casing for the automatic controllingmechanism.

In accordance with certain features of the invention, a single connection from the typewriter key levers is provided for both making the controller strip and for thereafter operating the typewriting machine therefrom. In Fig. 1, the casing the various shafts is removed therefrom to looking at Fig. 9 from of example td the lever mechanism is shownl which prov1des bearings for more clearly show theinclosed mechanism.

As so embodied, a series of rods 10 correspond to, and are in operative relation at their top ends with, the various key levers 2 of the typewriter, there being arod or bar 10 for each key lever. r

AThe embodied form of connection therebetween comprises a slot 11, formed in the upper part of the bar 10 beneath the key lever 2, and an adjustable stop-screw 12, mounted in the bar 10 and engaging with the key lever on the top thereof. Thus when the key lever 2 is depressed, the pin 11 will the 'bar 10 is drawn downwardly, 12 will draw the key lever 2 downwardly therewith, to cause the typewriter to print Y the selected letter.

Referring first to ing the controller strip, have their lower ends longitudinally reciprocable in apertures in a guide plate, 16, which plate extends across between, the side walls of the c asing. A

the mechanism for mak- The controller lso, when the screw the series of bars 10 and is fixed to,

strip .r to be perforated, comes into the machine over a supporting plate 17, and a hand-operated feed roller 18 serves to thread it through the machine over the plate 17. The shaft 19 of the hand roller is journaled in the side plates ofthe machine.

series of spring-operated, longitudinally-reciprocable punches are provided, equal in number to the typewriter key levers 2, these punches perforating -the controller sheet :c in conformity to the actuation of the key levers. As embodied, the perforating punches 20 are reciprocably carried in apertures in a supporting and guiding plate 21, extending horizontally across the machine and they are also similarly carried in apertures in a bottom guide plate 22, spaced from and extending across beneath the guide plate 2l. The perforating punches 20 are held resiliently in non-operating position byv suitable means, such as coiled, helical springs .23, the lower ends of which bear against plate 22 and the upper ends against stop pins 24, which pins also limit the upward the punches 2() is a horizontally and transversely-disposed die ,block 26, having apertures 27 corresponding to the ins 20.

The embodied orm of means for selectively perforating the controller sheet a: in accordance with the actuation, of the key levers 2, and for feeding the controller sheet yward end of these forward, extends across the casing and is supported in elongated slots 37 in the side walls thereof, so as to be horizontally slidable to and fro. Pivoted on rod 436 are a series of levers 38 corresponding to, and in operative' rela- 'tion with, the respective rods 10, the forlevers projecting into longitudinally disposed slots or openings 39 in the rods or bars 10.

Fixed ineach of the slots 39 and extend- -ing thereacross is a pin 40, which actuates the corresponding lever 38 when the corre.

sponding bar 10 is depressed by its key lever 2, and which is also used to operate the key lever as later described. Each of the levers 38 has a downwardly extending projection 41 adapted tocooperate with the cor, responding punch 20. Thus when a key lever 2 is depressed, the corresponding bar l0 is depressed therewith, and its pin 40 strikes the corresponding lever 38, and the corresponding punch 20 is driven Vthrough the sheet to perforate it for the selected character or function'of the typewriting machine.

Referring now to the mechanism for intermittently feeding the controller strip forward between successive perforations, a pair of levers 48 have mounted on the ends thereof a universal bar 47, which is located just beneath the various barsl 10. The

rod 49, 'which is eccentricomprises a bearing rod 36 which' levers 48 one of the levers 48 is in operati ve relation with a longitudinally disposed cam plate This cam plate cooperates with a cam ro-llcr 54, which is mountedat one end of a lever 55, pivotally supported at 56 on the machine frame.

A feed pawl 57 is pivotally connected at 58 to the lever 55. The tooth 60'of the pawl engages with ratchet teeth 61 formed on the feed roller 62 for the controller strip. A resilient feed roller 63 cooperates with the roller 62 lto press the controller strip thereagainst and .to cause it to feed accurately with the roller 62. Thus whenever a bar 10 is depressed in perforating the controller sheet, levers 48 are rocked by means of the universal bar, and cam 53 actuates lever to operate roller 62 to feed the controller strip ac one space. p

eferring now lto the embodied form of meansfor throwing the controller strip perforating mechanism out of operation, as is done when the controller strip operates the machine. A pair of arms 64 are pivotally connected to the transversely slidable rod 36. At theiropposite ends 65, arms 64 are pivotally connected to a pair of levers 66, which leversare and the lower ends of thel levers are bifurcated as shown at 68 to straddle the rod 49. A tension spring 69 impelsthe feeding pawl 57 to its initial or feed-beginning position. By rotating the disc 50 by a suitable hand wheel, forl a semi-circumference, rod 49 is 'thereby moved through a semi-circumference, and levers 66 are rocked to slide thev rod 36 to the right in Fig. 1. Bars 38 are thereby moved to the right from beneath the actuating pins 40 in the respective rods 10, and are thus brought to inoperative position, so that the machine may be used for writing,v as later described. The controller sheet perfprating mechanism is then in the inoperative posltion. v

`A` suitable detent and positioning mechanism for cylinder 62 during the perforating of the sheet is provided, (F ig.'8). A detent lever -70` passesv into and ,out of engagement with, teeth 71 on cylinder'62, the lever being pivoted at 72. A link 73 which is pivoted at 75 to one of the lever arms 48, already described, has a forked end that straddles a pin 74 fixed in lever 70, and normally holds it out of. engagement with teeth ently impels detent lever 7 0 into engagement with rocked in pivotally mounted -at 67,

f ential recesses 86, just feeding the stri counter-clockwise direction. By the foregoing mechanism, lever 70 will hold cylinder 62 stationary during the perforation of sheet and immediately thereafter link 73 will move detent lever 70 .out of engagement with the teeth 71 on cylinder v62. y

Referring now to the embodied form of mechanism forA operating the typewriter from the prepared controller strip m, a series of plungers or detector pins or fingers 80 are longitudinally reciprocably mounted in a supporting and guiding block 81, which extends across the machine, the detector pins or fingers corresponding in number to the key levers 2. Cooperating with the fingers '80 is a roller 82, which supports and feeds the perforated controller strip to present it to the pins 80, and having its surface Vformed to permit any pin 8O which finds its perforation in the controller strip tol drop and 'thereby actuate the typewriter mechanism as xroller 63 and a feed roller 84 preferably cooperate Awith the roller or cylinder `82in m. The roller 82 is provided, according y,

beneath each of the l fingers or pins 80, so that any'pn 80 may head 87, and

v in a bar 90, and thereby move downwardly whenever it finds a perforation y in the controller strip w.

Each of the pins 80 is provided with a a compression spring 88 is seated on a pin 89 projecting from the top of the head 87 and is also seated in afrecess resiliently presses the pin 80 -downwardly.\ Mounted for longitudinal reciprocation in a horizontally disposed aperture in each ofthe heads- 87 is an 108. The bail 108 is carried upon apai-r of onent 94. The pins actuating pin, or inter lead 95, which head 94 have each a yoked y straddles the tail .96 of a bell crank lever,

which lever is ivoted on a rod 97, extending across the mac ine. The other end 98 of the 'bell crank lever extends through the Corresponding slot 39 of the correspondingbar l10, arid is adjacent' to or rests upon the top side ofits pin 40. A spring 99 resiliently supports and restores the various levers- 98.

' A reciprocating universal actuating bar or bail -108 extends /across the machine, and when any ofthe fingers is in the downward position through finding its perforation y inthe controller strip w, its interponent 94 is broughtdnto horizontal alinement with and is actuated by the universal bar. When there is no perforation Vin the controller strip mcorresponding toy any finger or pinv 80, the finger is supportedV in its up position by the controller strip, and. its interponent 94 is above and clear lof the actuatingbail arms 109 of a pair of `bell crank levers, which are pivoted at either side of the maf chine upona rod 110. Fixed to one of said levers' is an arm 111, provided with a cam hereinafter described. The feed with annular circumfer-y der the action of gravity tory to the forward feed o'f the controller strip, and finding another perforation y in the controllerfstrip, are provided. As embodied, a universal bar 120 extends across the machine beneath the interponents 94. The bar 120 is supported at either end thereof in arms 121, fixed to a rod 122, which rod extends across and is liournaled in the side walls of the casing. Fixed to the rod 122 is an actuating arm 123, which arm is provided with a cam roller 124, runing on a cam 125, the cam being fixed on the shaft 116. The cam .roller 124 lis resiliently held to its cam by a spring 127.

Means are provided for intermittently feeding the controller, strip iforward from one perforation to the next beneath thc fingers 80 between the successive actuations of the typewriting machine from the perforai,

tions. As embodied, a feed pawl 130 cooperates with ratchet teeth 181 formed on the controller strip feed roller 82 at one side thereof. The feed pawl 130 is pivoted at 132 to a lever 133, which lever is pivoted ,and

both accurately positions and maintains the cylinder in position. As embodied, a det-ent lever 140 cooperates with a series of detent teeth 141, formed on the corresponding end of cylinder 82. Lever 140 is pivoted at 142, and is provided with a cam roller 143 which roller runs on a cani 144, fixed on shaft 116. A spring 145 resiliently holds the roller to its cam.

justdescribed is substantially as follows When .there are no perforations in the controller strip-j m, the spring, pressed pins 80 ride thereon and "maintain thecorresponding interponent rods 94 clear of the universal actuating bail 108. When, however, a pin' 80 finds its perforation y in the controller sheet w, it drops downwardly un- .and of its spring l88, and its rod 94 is thereby brought into line with the actuatingbail or bar 108. On4

the next revolution of cam 113,`bail 108 will push this interponent 94 forwardly, that is, to the right `in Fig.l 1, and levers 96 1.15 The manner of operation of the mechanism 2Q .nipulation by an uniform feed. In the end controller strip at for the and 98 will be rocked, and through engagement-with the corresponding pin 40 will actuate thev corresponding type lever 2 of the typewriting machine. Immediately thereafter, cam 125 will rock levers v123, 121 to swing restoringr bail 120 upwardly, which will engage with interponent rod 94 and thus lift the finger 80 out of its perforation y. Immediately thereafter cam 136 will actuate feed pawl 130 to feed the -controller strip :c forward one step.

In accordance with one feature'of the invention mechanism is provided, and also a controlling instrumentality, whereby the machine may operate continuously to print repeatedly the sanle letter body, while automatically selecting and printing a different address' each time, automatically without adjustment or maattendant. As embodied (Figs. 1, 9, 1() and 1 1), the controller strip upon the feed roller 82 is (endless, the two ends of the perforated strip z, representing the body portion of the letter, are connected together by a pair of feeding strips 150, adapted to cooperate with successively selected perforated strips or sheets a, representing the different addresses. v

The strips 150 and also the edges'of the controller strip mare provided at either side with sprocket holes 151, which cooperate with sprocket teeth on the feeds roller 82, in the usual manner to insure accurate and of the perforated letter body are provided perforatio'ns 152, which cooperate with the perforated address sheets a.

In Fig. 1l is shown a magazine 153 within which the address strips a are stored in a pile, and are impelled forward by suitable means, such as a spring 154. .It will be understood that this mechanism is shown somewhat conventionally, tice any known or suitable form of magazine and feeding mechanism may be provided. As embodied, a plurality of hooks 156 are formed on the top end of the address sheets a, and these project into the path of, and are in alinement with, the apertures ,152 in the tail of the controller strip A cooperating yfeed roller or series of feeddiscs 1657 may be provided. As the holesl 152 come into alinement with the hooks y156, the address strip is attached to the controller strip and is carried through the machine, and as` it passes over the roller 82 it will print the corresponding address.'

As the address sheet a passes over the top of the ,roller and comes down head first 'on the other side, the hooks 156 will slip out of the'holes 152 and the addressjsheet a will drop onto any suitable delivery device. After te body of the letter has been printed on the same sheet with the address, the

the mechanism operating but that in praciinding holes 152 will take a new address sheet out of the magazine 153 preparatory to printing the next letter.

By reason of the disconnectible connections between the key levers 2 of the typewriting machine and the actuating rods 10,

the automatic controlling mechanism may be manufactured and sold independently and may be very simply and quickly at-l tached to a ty )ewriting machine or detached therefrom.

the typewriting machine may be lifted off from the controlling mechanism,

and by.- setting the typewriting machine in place y unscrewing the screws 12,
