record-strip feed mechanism7 which locking device is furnished with a driving or operating mechanism receiving motion from some convenient member of the machine, and an interponent or controlling member controlled from thc record-strip to render the driving member of the locking device operative or inoperative on the record-stri p feed as required.

It is not considered necessary to give here any details of the mechanism of the keyboard composing machine for producing the repeat signal; such machines are Well lrnown and an example thereof is disclosed in the patent to John Sellers Bancroft and Maui-itz C. I-ndahl, No. QHAO, dated December 28th, 1909. An additional or special signalproducing element or punch can be f ittcd on the machine, or in order that existing machines may `be readily-adapted to produce the required signal the repeat signal can be composed of two signal components which together have not hitherto represented any symbol or the like but either of Which can be or has been hitherto used in conjunction with other components for a character or like signal. The mechanism of the present invention is so contrived that when two existing components are employed the presentation in the casting machine of either component separately or in conjunction with a component not concerned with the present invention, will not operate on the mechanism for interrupting the record strip feed on the casting machine. such mechanism bcing only operative when the two components are presented together.

In the best ltnon'n .'ommercial machines, the signals in the record-strip are usually perforations which aclV in conjunction with air conduits of a pneumatic s vslcm to operatc the die case or matrix positioning mechanism of the casting machine. The recordstrip is fed through the machine intermittcntl \Y by mechanism operated in timed relation with the casting mechanism. The mechanism for feeding` the strip generali)IY comprises a ratchet and pau'l nn-c'lianism which rotates pin wheels adapted to engage feed holes in the margins of the recordstrip. and the shaft of these pin wheels is rotated step h v step to present the perforations of the successive signals to a series of air conduits bv which thc die-case positioning mechanisms are controlled. The drivingl paul of the feed mechanism is operated in timed relation to the casting. and between the pawl and the driving meclianism there is interposed a vielding coupling so as to avoid damage to the mechanism `should the opera.- tion of the feed mechanism be interfered with.

In carrying out the present invention as applied to an automatic f vpe casting machine as above described. there is mounted contiguous to the record-strip driving mechanism, a pavvl and ratchet driven notched disk or cam member adapted to operate upon an arm which, when so operated upon, engages and holds the strip-feed ratchet Wheel; and the driving pawl for the disk is onl)Y rendered operative to effect the rotation of the disk the rer'luired degree blv the repeat signal which acts upon a pawl-posilioning member or motor.

Referring to the accompanying drawings:

The mechanism illustrated with which the pre-ent invention is shown embodied responds in general with that set forth in the patent to John Sellers Bancroft, No. 625.998 previouslv mentioned. and particularlv as to the paper feeding mechanism lo the improvements thereon shown for example, in the patents to John Sellers Bancroft,y No. 674,362 dated Mar 21st. 1901. and No. 700.289. dated Mav 20th, 1902. to which patents reference can be had for a detailed deserintion of the mechanism and its operation. Tt is sufficient for present purposes to point out some of the parts of the casting machine for identification purposes and lo refer to the parts cooperating and co-acting with the mechanism Which is more particularl)Y a part of the present invention. For example. in the casting machine shown in Fie'. l it will he suflicient to call attention to the metal pot 7 supported by the frame 8 capahle of being swung on the pivot screw il and of being elevated (as shown) or depressed lrv rotating the said screw 9 h v means of-the handle 10; to the flexible gas conduits ll for leading gas to the burners under the pot 7 and to the chimneyy l2 for conducting off the products of combustion of the gas: to the pump operating levers lf3. the pump piston spring I4. the pump body spring I5. the mold 16. the mold blade operating rod 17. the matrix carrier 1S. thc die case positioning mechanism represented b v the jaw or tong 171, the bridge 1D and the centering pin micrometer adjustment screws Q0. the centering pin lever 21, the record strip Q2 and the feeding mechanism frame 221. parts of which feeding meel-1anism are more particularly shown in Figs. 2. 3 and 4. It will. ofcourse. be understood ln' one skilled in the art that the various mechanisms of the machine sei forth cooperate-to produce east tjpe, in accordance with the lill) signals recorded inV the perforated strip, which strip is ,ordinarily fed aiong intermittently andpresents a new Vor a repeated signel for each-casting. The'present invention contemplates:mechanism for rendering the feed mechanism inactive,veherebj-Y one signal is held Vpresented While Vthe other mechanisms continue to operate and thus cast repeatedly the particular type represented by the signal. The means for causing Such ternporary suspension of the feed under control of a signal Will now be described.

The usual toothed Wheelj23 ofthe paper feed device is mounted upon the shaft 24 of the feed pin Wheels 25; YThe driving pawl 2G is mounted on a ring 2? which receives an oecillatin motion from a rocking arm 28 through linke- 29 and 30 and a resilient coupling 3l. A holding pawl 32 for the Wheel 23 is operated through the link 30. The interpreting mechanism including the air har for the record strip is provided with a series of air ducts or conduits leading to gages for the die case positioning mechanism, and between which ducts and an air supply bar or chamber the record strip 22 passes.

ln embodying the present invention in a machine auch as above referred to, advantage is taken of the holding pavvl 32, which is employed to act as the feed locking inember pro er, under the Vcontrol of the mechanism o the present invention. In passing it is to he noted that in commercial machines such referred to, this holding paivl has' been employed under certain conditions to lock the paper feed; when sorts or single types have been cast and when the machine ie not controlled by a record strip representing a piece of composition, it has been'usual to place in the interpreting mechanism a piece of material perforated for a single signal so thatithe die holder will he maintained in :meurateV position by the positioning mech- 43 fanism. In such cases theV record-strip feed tween the feed strokes of the pawl 26 untilV the repeat signal is presented.

Mounted upon an extension or arm of the frame A36 is a notched disk or com 37 which mayI have four notches as shown in Fig. 2, or one notch as shown in Fig. or two asfshown in Fig. 6, in accordance with the predetermined number ofY caste which each repeat signal is intended to denote. ,When one orY other of the notches 3'? is'rover a projection Y39 on the pawl 32 the latter is free to respond normally tothe action of-its driving mechanism 30, 31,' hut when the normal surface of the disk 37 is over the projection 39 the paw] 32, as will be seen in Fig. 2', is locked in engagement; with the Wheel 23, and its driving mechanism operates without moving the pawl, and such action is permitted by the resiiient coupling or spring box 3i.

Mounted on the shaft 40 of the disk 3T is a ratchet Wheel 41 which is arranged-to be rotated by a pan-'l 42 pivotally carried on one endV of a lever 43 which is loosely mounted on the shaft 40.

The other'jend of the lever 43 is connected by a link 44V with the rocking arm'S' fromY which it receives motion to operate the pawi 42 to rotate step b v sten the disk 37.V

When Vthe machine is casting ordinary composition and the repeat signal has not heen presented, the disk 37 is in the position shown in Fig. 3, with a notch 38, over the pawl 32 and mechanism is provided o v which the driving pawl 42 for the wheel 4l is prevented from engafring the teeth of the wheel so that the disr 37 is stationary. Conveniently this mechanism comprises a bell crank iever pivotally mounted at 46 on the lever 43 and having one end engaging one end of the paWl 42 or a shoulder thereon. Beneath this pavvl engaging arm of the lever 45 is a stop 47 carried by the machine frame and adapted to en age the arm and disengage the pawl 42 om the Wheel 41.. The lever 45 is so mounted that it remains in the position it is placed in by the stop 47 until acted upon by another meinber which will he the interponent or operatingmember controlled by the repeat signal.

hns, during normal composition, the pawls 26 and 32 control through the driving mechanism 28, 3l, 29, 30 the feed of the strip, and although the members 44 and 43 are being operated to rotate the Wheel 41 this is rendered ineffective on the wheel by reason of the action of the stop 47 on Vthe pawl engaging lever 45.

:For rendering the repeat signal operative, on the r'nechanismV 37, 45 n'lechanismv is provided in accordance with this invention for moving the lever 45 from the osition in which it is placed by the stop 47 into a positiori'in which it will turn the paivl so that it Will engage and drive the Wheel 4l.

In the present embodiment of the invention, the interponent 48 which act-s upon the lever 45 is controlled by a repeat signal consisting of two cxistin components which if presented sin ly or cit er'of them in company with anot er component will not operate the interponent 48, as the mechanism is so contrived that it requiresE the simnltaneous presentation of the tivo components of the repeat signal to operate the interponen-t 4S. Y

The interpellent 48 is connected to a piston 49 located in a cylinder 50, one end of which, through a conduit 51, communicates with a valve chamber 52 in which there is a valve opening 53 normally closed by a valve 54. Beyond the valve chamber is a chamber 55 in which is located a piston 56 the rod of which projects through the wall between chambers and 55 and is connected to the valve 54. The interponent 48 is returned and piston 49 is held normally against the inner end of the cylinder by a spring 57, and the valve 54 is normally held against its seat by a spring 58.

Leading into the valve chamber is a conduit 59, the air supply to which is controlled at the air bar 33 by one component of the repeat signal, and leading into the chamber 55 behind the piston 56, is a conduit G0 the air supply to which is controlled at the air bar 33 by the other component of the repeat signal.

When the two components of the repeat signal are presented, air passing through the conduit 60 moves the piston 56 forward, and the valve 54 is moved from its seating. At the same time air enters the valve chainber 52 by the conduit 59, and passing through the valve opening travels through conduit 51 in to the cylinder 50, pushing the piston 49 and with it the interponent 48 outward.

The interponent 48 is moved to its outer position each time the signal is repeated and strikes the free arm of the bell crank when the latter reaches the end of its upward stroke which is the idle stroke of the pawl 42 so that the bell crank 45 is rocked by the member 48 to more the paw] into position to engage the teeth ot.' the wheel 4l. The upper dotted line position of the lever 45 and pawl 42, as shown in Fig. 2 is the same relatively to the lever 43 as the position shown in full lines. An advance of the interponent 48 when the parts are in the dotted position causes the tilting of the lever 45 and the engagement of the paWl 42 with the teeth of the Wheel 41, this engagement continuing until the lever 45 strikes against the adjustable stop 47.

The wheel 41 is provided with twenty teeth, and when driven by the pavvl. 42 is moved the distance of one tooth at each operation, and cach complete stroke of the arm 28 represents a casting.

In the example shown in Fig. 2 the disk 37 has four notches so that each presentation of the repeat signal effects the arrest of the record-strip for five castings.

On the first stroke of the arm 43 after the repeat signal has been presented, the disk will be turned the distance of one tooth of the wheel 41 which will bring the shoulder of the notch into contact with the projection 39 of the holding awl 32, and this pawl will be locked until, by the step by step movement of the wheel 41, the next notch in the disk l37 comes over the projection 39 which will be when five casts have been made from a particular matrix, the signal for the positioning of which was presented by the record-strip simultaneously with the repeat signal. Should the next signal presented be a repeat signal the cycle above described will be repeated. When the repeat signal is withdrawn the piston 49 and interponent 48 are returned by the spring 57 and air is allowed to escape from the cylinder 50 by the conduits 51 and 61.

With a disk having four notches five successive casts can be represented by one signal. Should a greater number of casts than tive be desired from one signal, a disk having a different number of notches may be employed; for example, with the disk with two notches shown in Fig. 6 ten casts will be represented by one signal, and with a disk having one notch shown in Fig. 5, one signal will produce twenty casts.

In order to facilitate the changing of these disks there are mounted upon the face of the wheel 41 two pins 62 which pass through openings in the disk and support it, and a ring 63 is placed in front of the disk and the whole detachably secured by a nut 64.

Should the repeat signal comprise or consist of a special perforation which is not employed alone or in combination with others to represent a character, etc., then the interponent Would be projected by the air from the conduit controlled by that per- 100 foration, and this conduit could open into the cylinder behind the piston 49, the valve 54 and piston 56 being unnecessary.
