To all whom it may concern;,

Be it known that I, FRANK R. FORD, a citizen of the United States, and a resident of the city and county of Philadelphia and State of Pennsylvania, have invented new and useful control by. means of an electric translating device the operation of printing'presses, foldin g-machines, the. ,and also automatic'feeders,

and to control the electric circuit for this translating device by means of the sheets,

whereby when the sheets are properly fed the operations of the feeding and other machines will be continuous, but a sheet improperly fed will operate the electric circuit for the translat-ingdevice and so discontinue the operation of oneor more of the various mechanisms controlled by the translating device. The translating device preferred is an electromagnet operating an armature, but

' of course other forms may be employed if found desirable.

The invention consists of the various fea-v which like letters designate similar parts, Figure 1 is a side elevation of a well-known type of printing-press known as stop-cylin -der 0 erativel connected with an automatic feeder, with both of which my improvements are combined. Fig. 2 is a side elevation of a detail, showing therstop-levers for discontinuing the operations of the press and feeder. line 3 3 of Fig. 2.

elevation of the gage for controlling the feeding of the sheets from the feeder. Fig. 7 is an elevation of the gage,'looking in the direction of the arrow in Fig. (3. Fig. 8 is a plan view of a portion of the feed-tablc,sho.wing the feeding-tapes and the gages. Fig. 9 is a fragmentary perspective view of the stop mechanism for arresting the movement of the automatic paper-feeder. Fig. 10 is a transverse section ofthe actuating-levers and the electromagnetic catch for holding the same. e

The stop-cylinder press and the automatic feeding mechanism illustrated only in skeleton are herein shown and described merely as types'of machines with which my improvements may be advantageously employed, and are not to be understood as limiting the application of the improvements to these particular machines.

A is the cylinder, and A is the bed of the press.' B is the drive-whee1 of the press, made fast on the shaft B and actuated by the powershaft 13*. Loosely carried by the shaft B is a sprocket-wheel 0, adapted to actuate, by means of a sprocket-chain O, the automatic 8o feederD. 'lhcsprocket-wheel O is'eonnected with or disconnected from the shaft B y any suitable coupling mechanism, the pr ferred form being constructed as follows a is a do'g pivoted on the sprocket-Wheel and provided at its front end with a hook, which is adapted to engage with a couplinglug a, formed on'a collar which is secured to the shaft B.

a is a spring whereby the hook of the dog 0 is yieldingly held in engagement with the lug'a. a is a shifting-disk pivoted on the sprocketwheel and provided with a pin a which ongages with a'slot a in the rear arm dog. .Upon turning the shifting-disk in one or the other direction the dog is moved into or out of engagement with the lug a.

a? is a trip-levcwhereby the shifting-diskis turned for disengaging the dog from the zoo coupling-lug a. This lever is pivoted on the "main frame and is adapted to engage withits of the- 5 upper arm against a pin a on the shiftingdisk for turning the latter and disengaging the dog from the coupling-lug. During the normal operation of the paper-feeder the upper arm of the trip-lever is arranged outside of the path of the pin (1 as the latter rol ates with the sprocket-wheel C, so that the dog permitted to remain in engagement with the coupling-lug.

a is an elbow-lever pivoted on the main frame and having one of its arms connected with the lower arm of a trip-lever by a rod 0.

a is a transverse rock-lever pivoted on. the main .frame and connected ith its outer arm to the other arm of the elbow-lever by a rod a 0 iso. rock-lever pivoted on the main frame and connected at its rear end with the inner arm of the transverse rock-lever a.

E represents a hand-crank or rock-arm provided with a cam e and mounted loosely on a transverse shaft 6. This cam engages with a roller on the front arm of the rock-lever. Upon swinging the hand-crank E forwardly, as represented in Fig.9, the cam depresses the front arm of the rock-lever, and this movement is transmitted by the intermediate mechanism to the trip-lever for holding the same out of the path of the .pin a of the shifting disk. Upon swinging the handcrank E rearwardly the trip-lever is turned so that its upper arm stands in the path of the pin a whereby the latter upon striking the trip-lever causes the shifting-disk to be turned and the dog to be disengaged from the coupling-lug, whereby the operation of the paper-feeder is arrested regardless of whether or not the press continues its operation. The front arm of the rock-lever c is caused to follow the cam c by a spring 7, secured with its ends to the rear arm of said lever and the main frame.

F represents a handera-nk or rock-arm sccured to the shaft 2' and provided with a cam f. The cam f is arranged to engage lug or roller-f on a rod G, pivoted at its upper end to the thrust-bar G, provided with the notch g and operziting to oscillate the arm II, which in the wellknown way serves to start the cylinder periodically at the proper time. \Vhcn the crank F is thrown forward f om the wheel I3, the rod (l drops, so, that the bar (l engages the arm II; but when the crank is thrown in the opposite direction the cam f lifts the bar II out of engagement; and the printing operation is discontinued, although in the style of press shown in the drawings the bed Acontinues to reciprocate, as is well known. It is not considered essential to show or describe more fully than has been done the various elements of the printing-piess, for they are old and well known in the art.

The crank E carries a Sprlngbolt h, normally engaging a socket h in the crank F, but arranged to be disengaged therefrom by a handle It", so that these cranks may be operated simultaneously or dissimultaneously,

as desired. The shaft 6' carries a crank K, to which is connected one end of a suitablysupported thrust-rod 7o, actuated by a spring 7t" or other suitable meansto throw the shaft (2 and the cranks K, F, and E back-ward into the position shown in Figs. 1 and 2. \Vhen the crank E, or both the cranks E and 1 are thrown forward by hard from the wheel I3, the shaft 6 is turned and the crank K and rod 7; are pushed back against t'he sprin g 7:. The cranks If and F, it will be seen, operate separate stop mechanisms for the feeding and printing mechanisms which they respectively control, and when thrown forward by hand.

from the wheel B put these feeding and print in; mechanisms into operation. The thrustrod 7;, by means of the spring it, however, gives these stop mechanisms a normal tendency to discontinue the operations which they control. In order to hold the stop mechanisms against this normal tendency, an electric circuit in. is provided, including any suit-- able translating device, but preferably a magnet M. This magnet operates a latch N, adapted to engage the crank F when thrown forward against the stop a. The circuit or includes a contact 1-), carried by an oscillating arm P, mounted on. a rock-shaft P. This shaft is actuated by arod 11, connected with the automatic feeding mechanism 1), and when the arm P comes down the contact 1) is adapted to touch the'contact-plate 1)", carried by the cylinder, and thnscomplcte the circuit for the magnet M, the circuit from the plate 1) to the nmgnet being completed through the plate 1), the blanket-holder 1F, rot'Lp Fig. l, head of the cylinder, cylinder-shaft,and frame of the press to the magnet Ml lvhen it is desired to disconnect the. flock-shaft P from the feeding mechanism, tllieb'od I? may be disengaged and ard 1'. A spring 1', connected at or o end to the standard and at its other end with the rock-shaft, serves to turn the shaft and lift the arm I out of the way when l'llCJttl is so disengagcdi 3 S are the feedingtaprsion the feed-table for carrying the sheets or. paper or other fabric to the cylinder. They are preferably, as shbwn, operalji'vely connee id with the rest of the feeding meehanism.

Every time a sheet has been (10ll\'(fl'0d to the grippers of the cylinder the rock-arm carrying the contact 1) moves toward and from the contact 1). If the sheet has been properly presented to the grippers, it covers the contact 1) and serves as an insulator to prevent the circuit from being closed during the descent ofthe contact 21 upon the contact 1)", thereby preventing the magnet from becoming energized and releasing the crank-arms'lfil and I". In the event of no sheet being fed to the grippers of the cylinder or of a sheet being improperly presented to the grippers, so as to leave the contact 1; uncovered, the

supported uponl a stand contact 1') indescending upon the contact 1) thereby energizing the comes 3 latter attracts the armature or catch N and withdraws the shoulder of the same from engagement with the crank or rock arm 1',

thereby releasing the latter, together with 5. the rock-arm E, and permitting the-spring 7c to swing these arms backward for simultaneously stopping the operation of the feeder and the press.

In the path of the sheets as they are carried down by the feeding-tapes are two gages T, mounted on opposite sides of the feed-table. A convenient way of mounting these gages is to secure them to a bar fixed across the feed-table between the folds of the tapes, and they may beina-de adjustable on the bar, as shown in Figs. 6, '7, and 8, by means of setscrcws u. The gage comprises two armst f, arranged in substantially U shape, the arm being clamped to the bar U by the setscrews it. Through the end of the arm 15 passes a screw having a notched. head eand.

a spherical foot 1;, adjustable to and from the anvil w. A spring fixed on the arm I, engages one of the notches and locks the screw in any position desired with relation to the anvil 20. By these means the gages may be adjusted on the bar U to suit any width of paper,.and the jaws of the gages, comprising the foot c and anvil to, may be adjusted to permit the side edges of paper of any thickness to pass bctweenthcm, but to stop the sheets if more than one is simultaneously presented. The form of gage shown is preferred, but of course other forms adapted to accomplish the same .result might be employed, and one or more than two gages might be employed instead of two.

Theoperation is as follows: The crank is thrown forward by hand from the wheel 1;, the bolt h having been withdrawn, and the feeding mechanism is started. \Vhcn' the sheets are in proper position and the bed A is making its back stroke, the crank F is thrown forward by hand against the stop it and behind the latch N, the bolt 7t engaging the crank F and thereby locking the cranks E and F together. The printing mechanism is now started. The cylinder and arm I are so timed that the arm 1 carries its contactpoint '1) down .upon the plate just before the grippers seize the sheet of paper.

(indicated by the broken line, Fig. 5) will lie on top of the platep, so as to insulate the c On-- tacts and prevent the ei'lergization of the magnet, so that the operation is continued. If, however, no sheet has been fed, or if a sheet has not been properly fed, as indicated in this second case by the dotted line .2, Fig.

- and also preventing a continuation of the ifeedin'g-of the sheets and their disarrange lf the sheet has been properly fed, its lower edge.
