AUTOMATIC REGISTER-GAGE FOR PRINTING-PRESSES.

SIEECIFICATION forming part of Letters Patent No. 674,532, dated May 21, 1901.

Application filed August 18, 1900. Serial No. 27,315. tNo model.)

To all whomit may concern:

Be it known that I, CHAUNOEY H. BOOTON, aciuzen of the United States,residiugat Gallipolis, in the county of Gallia and State of Ohio, have invented a new and usefulAutomatic Register-Gage for PrintingPresses, of

which the following is a specification.

This invention relates to an automaticallyoperating register-gage for printing-presses,

and contemplates the provision of simple and. effective means of this character for causing an accurate registration of the sheet without requiring precise manual adjustment thereof and permitting a press to be run at a materially greater rate of speed than heretofore with a corresponding increase in the output of work within a specified or given time and a more satisfactory result vin the quality of the work and marked economy in the use of '20 material, the gage being applicable to any form of platen-press and used only on one side of the tympan and occupying no more space than the ordinary side pins now in use and serving to place the sheet in proper position irrespective of a regular or irregular feed of the same.

The invention consists in the construction,

combination, and general organization of the several parts of the gage in general and in 0 detail, which will be more fully hereinafter.

described and claimed, and subject to a wide range of modification,which will be indicated hereinafter by reference to the several variations, and also indicating that other changes in the form, size, proportions, and minor details may be resorted to without departing from the principle of the'invention.

In the drawings, Figure l is a perspective view of a portion of a press, showing the gage 40 forming the subject-matter of thisinvention applied thereto in operative position. Fig.

showing a modification in the construction.

Fig. 8 is a detail perspective view of a portion of the operating-arm, showing a further modification. Fig. 9 is aplan view of a p0rtion of the improved device, showing aslight modification.

Similar numerals of reference are employed to indicate correspondingv parts in the several views.

The numeral 1 designates a supportingplate, preferably constructed of thin metal of a non-corrosive nature and having adjacent one end, near the outer edge, a pair of fulcrum ears or lugs 2, having a longitudinal direction relatively to the plate and spaced apart from each other a suitable distance for the pivotal reception of the rear bifurcated terminal 3 of an operating-arm 4 and normally held outward or away from the plane of the plate 1 by a spring 5, engaging the pivot thereof and of such strength to always. cause the said arm to return to its outward nor-] mal position when free to do so. This operat-. 7o 4 ing-arm can be constructed in many-different designs and be supplied with various attachments to render it more convenientin application to difierent styles of printing-presses and more efficient in its operation. One of the most important of these attachments or convenient provisions consists in a sliding ex tension 6, having a rear terminal guide 7, movable on the said arm and both engaged by a looking or clamping slide 8 for holding the parts against accidental movement after a desired adjustment has been obtained. It will be observed that by the use of this attachment the arm may be operatively lengthened or shortened to compensate for the proportions of various kinds of presses, and at its inner end the said extension has an outward projection 9 at an angle thereto for contact with a gripper or other part of a press, which will cause the arm as an entirety to be 0 pressed close to the plate 1, and thus actuate change is indicated by Fig. 8 and consists in too mounting an antifrictional bearing-roller 10 in the inner or contacting terminal of the arm for use in connection with that class of presses that do not employ grippers and to bear against the press-body or furniture adjacent the tympan, and in this instance the said arm will be used without the extension, though there may be instances where this featureof the roller could be effectively employed in connection with the said extension, and such use of the roller is contemplated.

At the inner end of the plate 1 transverse guides 11 are secured and have their opposing edges inclined to form a dovetail seat for the freely-movable reception of a slide 12, having opposite beveled side edges and an inner angular head 13 at a right angle thereto and providing What may be concretely termed a pusher or slidable sheet-placer. The slide 12 has an outwardly-projecting stud 14 to receive the inner end of a retractile spring 15, attached at its opposite end to a suitable projection 16 on the plate 1. This spring may at times be dispensed with, as will be hereinafter set forth; but when used it operates to return the pusher or placer to normal position, and the automatic operation of the latter device to perform the function for which it is devised is caused by the operating-arm and intermediate connections between the latter and said pusher or placer. The head of the pusher or placer is engaged by the outwardly-deflected inner terminal of a controllinglever 17, which is loosely disposed on and unattached to any part of the slide or head, the rear or opposite terminal of the said lever being pivoted to or fulcrumed on the plate 1. The outer edge portion of the lever, adjacent the pivot or ful crum thereof, is provided with an open socket 18, as clearly shown by Figs. 2 and 3, and loosely engaging therewith is a ball 19 on the inner end of a connecting screw-shank 20, having a polygonal fixed collar 21 for adjusting the same relatively to asocket 22, carried by a ball 23 and maintained in adjusted position by a jam-nut 24. The ball 23 loosely engages an open socket 25 on the inner edge of the arm 4, and thus a double ball-andsocket connection is formed between the lever and arm, which has a normal upward inclination from the lever toward the arm and the alternate depression of the arm, and the return of the same to its normal position in an automatic manner by the action of the spring 5 will cause a differentiation in the distance between the contiguous edges of the lever and arm and alternately force the lever inward and draw the said lever outward and correspondingly move the pusher or placer inward and free the latter for outward normal position. When no spring is used for retracting the pusher or placer, the slide thereof will be provided witha pin 26, as shown by Fig. 9, for engagement with the free end of thelever to return the said pusher or placer to normal position, and the sockets for the balls at the opposite ends. of the connection in this instance will be closed, as

shown. Itwill also be understood that the forms of connections set forth will prevent jarring or abrupt vibration of the lever, and the pusher or placer will consequently always have a regular stroke, and this latter desirable movement of the lever will also be due largely to the elongated construction of the arm, and therefore no matter howrapidly the ment, and between these two sockets a stiff link 28 is interposed and formed with terminal balls 29, located in said sockets. From this showing it is to be understood that the adjustable feature of the ball-and-socket connection is not essential to the practical operation of the gage, and when the last-described ball-and-socket connection is used the retractile spring for the pusher or placer can be dispensed with and the pin 26 (shown by Fig. 3) substituted in lieu thereof and which is an obvious substitution.

In applying the improved device to the tympan, as shown, it is preferred that the tympani-sheet he of a strong and durable nature to support the gage attachment without tearing. The under side of the plate 1 is supplied with a layer of glue or other adhesive material and placed on the said tympansheet, and in theevent that the device is not evenly or regularly positioned the irregularity can be rectified by adj usting the screwshank 2O relatively to the socket 22 to cause the pusher or placer to havea regular stroke. The operating-arm is regularly positioned relatively to the gripper at one side or other part, and the sheet to be printed is fed to the machine and rests against the usual pins or stops extending outwardly beyond the ty mpan-sheet, and as the parts of the press are moving the operating-arm is pressed toward the plate 1, and thereby actuates the pusher or placer to dispose the fed sheet in proper registering position in an easy yet quick manner without jar or jolt. The portion of the head ofthe placer or pusher that normally rests close to or against the inner edge of the plate 1 projects slightly beyond the inner plane of said plate to compensate for the layer of glue or other adhesive material and cause the innermost edge of said head to bear closely against the tympan-shcet, and thereby always insure engagement of the head with the sheet edge and prevent the latter from working under the plate. The pressure on the operati ngarm will be exerted against the inner free end of the same in the direction of the outer side of the same and not against the endin a longitudinal direction, and consequently the inner end of the plate will be forced firmly IIO against the tympan-sheet, and thereby also tend to hold the head of the pusher or placer in close operating relation to the tympansheet.

It will be observed that the gage has been devised and is equipped with means for overcoming the complex structure and unsatisfactory operation of previous devices of a similar character, and it will be particularly noted that the organization of coacting members are compact and close in without material projection to avoid interference with the working parts of a press and that it occupies very little room. The use of only one of the devices is necessary, and the cost of manufacture and application is reduced to a minimum from a comparative standpoint. ln fact, the presses are permitted to run at such a great-er degreeof speed with positive results and accurate work by the application of the gage embodying the features of the invention that the operation of the press of whatever kind is materially reduced in cost, as the capacity of the same is increased by the rapid feed permitted by the gage with accurate results and a better quality of work than has heretofore been attainable with a slower movement.

Many other advantages will appear to those using the improved device, and it will be appreciated that the'gage is not confined in its application to any particular style or kind of press.
