Application filed January 14, 1905. Serial No. 241,138,

To (LZZ whom, it may concern.-

Be it known that I, FERDINAND WESEL, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Folio-Mortising Machines, of which the following is a specification.

My invention pertains to metal cutting machines, more particularly machines for cutting electrotypes and analogous plates and it has for one of its objects to provide an accurate and expeditious folio-mortising ma chinei. 6., a machine calculated to correctly and quickly mortise an electrotype or like plate, so as to adapt the same to snugly receive folios or numbered blocks or interpolated blocks of other descriptions.

Another object of the invention is the provision of a duplex folio-mortising machine that is to say, a machine at which two workmen acting independently of each other can accurately and expeditiously form mortises in electrotypes and other plates for the reception of folios and other blocks.

Other objects and advantages of the invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation of so much of the machine constituting the present and preferred embodiment of my invention as is necessary to illustrate the said invention. Fig. 2 is a top plan view of the machine with plates to be cut properly secured in position, one of the said plates being shown as presented to its complementary cutter and the other plate inthe position it occupies precedent to being moved into engagement with its cutter. Fig. 3 is an enlarged top plan view of one of the gages comprised in my improvements. Fig. 4'is a detail top plan view, on an enlarged scale, of one of the carriages of my novel machine and the parts appurtenant thereto, the said carriage being shown with an electrotype secured against casual movement thereon and being also shown in proper position relative to its complementary cutter. Fig. 5 is an enlarged detail top plan view illustrative of the adjustable plates, which are adapted to accommodate cutterblades of various thicknesses between them. Fig. 6 is a detail view illustrative of one of the slides carried by the carriages, the workclamps on said slide, and the screw for feeding or moving the slide. Fig. 7 is an enlarged vertical section taken in the plane indicated by the line 2 2 of Fig. 2 looking in the direction indicated by arrow, and Figs. 8, 9, 10, and 11 are views illustrative of the capabili ties of the machine and hereinafter referred to in detail.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which, A is the main frame of my novel machine, which may be of any construction compatible with the purposes of my invention, although I prefer the construction illustrated, which comprises a table B, as best shown in Figs. 1 and 2.

O is a shaft journaled in bearings a on the main frame and extending lengthwise of the machine in a vertical plane at one side of the table B and equipped with a pulley I), designed to be connected, through the medium of a band, (not shown,) with an electric or other suitable motor.

D D are rotary cutters fixed on the shaft C at points adjacent to the ends thereof and respectively made up by preference of a head 0 and blades d.

E E are casings containing the cutters D and havingfor their purpose to prevent flying cuttings from injuring or interfering with the work of the operatives, and F F are chutes communicating with and extending downwardly from the casings E and designed to convey cuttings to a box or other receptacle placed to receive the same. The casings E are preferably formed in part of transparent material (indicated by e) in order to enable the workmen to see the cutters which are designed to be rotated in the direction indicated by arrow, and said casings are provided in their fronts with horizontal slots or openings f, Fig. 7, in order -to permit of the proper presentation of the plates to .be cut (which areindicated by g) to the cutters.

G G are pairs of rails fixed with respect to i the main frame A and disposed above the table B and at right angles to the shaft C, and

' H and I are carriages arranged on the said pairs of rails and designed to be moved by hand or otherwise toward and from the cutters D. The carriage H is provided with a dovetail slide J arranged therein, extending slightly above the upper side thereof and movable with respect thereto in the direction of the length of the machine or at right angles to the I cutters. The said dovetail slide is provided with a depending nut h, movable lengthwise of the machine in a slot 7, of carriage H, and is IIO also provided wth a slot 7c, which extends from a point adjacent to its inner end to its outer end and has its lower portion enlarged, as best shown in Fig. 7. The nut h of the slide J is designed to receive a feed-screw K, while the lower portion of the slot 7c of the slide is designed to receive enlargements Z at the lower end of bolts m. These bolts m extend upwardly through the comparatively narrow upper portion of the slot 7c and are provided above the slide with coiled springs 19, cam-levers r, and clamps s, the said clamps being interposed between the cam levers s and the springs and being provided at their outer ends with depending portions t, arranged to bear against the upper side of the slide J, and at their inner ends with cushions or pads u, of leather or other suitable material, designed to bear on the electrotype or other plate to be out. By reason of the construction just described it will be observed that when the parts are in the relative positions shown in Fig. 6 a plate may be read ily interposed between the padded ends of the clamps s and the upper side of the slide J, also that when the cam-levers r are swung outwardly the plate will be securely fastened between the clamps and the slide J. It will further be observed that with the levers r in the position shown in Fig. 6 the bolts 'm and the springs, clamps, and levers thereon may be moved in the direction of the length of the slide, so as to position the clamps to hold plates of various widths, also that a plate may be adjusted with respect to carriage and cutter. The carriage H is further provided with brackets L, having depending arms '0, which are vertically slotted for the passage of screws w, through the medium of which they are connected to the front edge of the carriage in such manner as to permit of their vertical adjustment with respect thereto, this being advantageous in order to permit of the rearwardly-extending arms a: of the bracket being readily raised and low ered to accommodate plates of various thicknesses between the gage M, carried by said arms a; of the brackets, and the upper side of the carriage H. Said carriage H is still further provided in its forward portion with a notch N, disposed in alinement with the blades of the cutter D complementary to the carriage. The width of the said notch Nis determined by plates P P, which are connected to the carriage by screws y taking through slots 2, Fig. 5. The plate P is provided with an arm 0/, which laps the plate P at the rear thereof with a view of holding said plates in truealinement with their contiguous edges parallel, and by virtue of the manner described of connecting the said plates P P to the carriage H it will be observed that the width of the notch N at the top thereof may be readily increased or diminished to snugly receive cutter-blades of various thicknesses. The gage M, which is connected to the arms :20 of the brackets L by screws b and is best shown in Fig. 3, is provided in its transverse center with a notch c, which extends rearwardly from its forward edge, is alined with the before-described notch N and terminates at its rear end in a longitudinal slot or T-head d, a notch e, which is alined with the notch c and extends forwardly from the rear edge of the gage, and oblong openings or notchesj", which are disposed at opposite sides of the notches ,c and e and equidistant therefrom and extend forwardly from the rear edge of the gage parallel to said notches c and e and terminate at their inner ends in T-heads g, disposed in alinement with the T-head d.' The inner walls of the notches f are beveled and graduated, as indicated by h, the graduations being preferably appropriate to what is known in the printing and electrotyping art as the point system. The gage M is further provided with the inscriptions line of cutter, which line is coincident with the outer walls of the T-heads d and g and graduations such as those designated census and quarto. It is obvious, however, that the said inscriptions and graduations may be omitted from the gage without involving a departure from the scope of my invention, also that graduations other than those designated census and quarto may be provided on the gage without affecting my said invention. The feed-screw K of the slide J is provided on its outer end with a handwheel Q, through the medium of which it may be turned with facility, and the said hand-wheel is provided in turn with an indentation or other mark is, which is designed in connection with a pointer Z, fixed with respect to the carriage H, to enable the operator to accurately determine when he has made a complete revolution of the said feed-screw. In practice the feed-screw K is preferably so arranged that one complete revolution thereof will move the slide J and the electrotype or other plate a distance corresponding to six points of what is known in the printing and electrotyping art as the point system.

. In the practical use of the carriage H and its appurtenances, in connection with its complementary cutter D, an electrotype or analogous plate is secured on the slide J through the medium of the clamping means before described and best shown in Fig. 6, and if the said plate is to be provided with a mortise in the center of its forward end it is positioned precedent to being clamped on the slide so that the opposite longitudinal lines of its type or other subject-matter rest coincident with a certain couple of graduations at the rear edge of the gage M. For instance, if the electrotype is a quarto electrotype the opposite longitudinal edges of its type or subject-matter are placed so as to register'with the quarto graduations of the gage, and with this done it follows that when the mortise is cut in the end of the electrotype it will be in the center of said end. The depth of the mortise to be formed in the end of the electrotype may be readily determined by the operator properly positioning the electrotype with reference to the graduated scales h, and with this done the electrotype is clamped on the slide J in the manner be fore described. With this done the carriage H is moved forwardly until itsforward edge a Fig. 2, brings up against the portion a of the main frame, when the cutter D will have made the mortise desired. When the elec trotype or other plate to be mortised is too narrow for the designated couples of graduations at the rear edge of the gage M to be used, the position of the electrotype may be determined by alining its type or subjectmatter with either of the walls of the notches f, and in this way the said type or subjectmatter may be accurately alined with the blades of the cutter. If the blades of the cutter are of a thickness of, say, eighteen points and it is desired for the mortise to have a corresponding width, the plate is merely presented to the cutter in the manner described, and the result will be an eighteen-point mortise, as shown by dotted lines in Fig. 8. If, however, a mortise of, say, twenty-four-points wide is desired, the plate is fed to the cutter and the feed-screw K is turned through one complete revolution, when, as will be readily appreciated, the plate will be fed at right angles to the cutter, and the result will be a mortise such as shown by dotted lines in Fig. 9. The said mortising of the plates is for the accurate and expeditious removal of folios such as shown in full lines in the lower portions of Figs. 8 and 9 and the substitution therefor of folios bearing other numbers. The said folios are placed and soldered in the mortises, and the result is an electrotype or analagous plate quite as perfect and durable as the original one. The cut to be made by the cutter in the'end of the electrotype or other plate is not limited to the twenty-fourpoints mentioned, but, on the other hand, 1s only limited by the extent to which the electrotype may be fed through the medium of the screw K. For instance, if the cut is to have a width of thirty-six points the feed-screw K is turned through three complete revolutions, this giving a feed of eighteen points, which in addition to the eighteen points of the cutterblades will afford the cut of the width desired. The mortise shown in Fig. 11 is formed in the sarfe way as that shown in Fig. 9, but is of a less with than the litter. The mortise shown in Fig. 10, however, is formed by determining the position of the 'electro- M i.'e., by registering the line of type at the left of the electrotype with the left wall of the said notches. When the mortise is to be formed adjacent to the forward right corner of the electrotype, the line of type at the right of the electrotype is registered with the right wall of the notches c and 6.

From the foregoing it will be readily appreciated that the operator at the right of my novel machine is enabled, through the medium of myimprovements, to very quickly and accurately mortise an electrotype or analagous plate and determine the position and extent of the mortise, and hence a large number of the plates may be mortised in a short period by a single workman, which is a desideratum.

In order that the operator at the right of my novel machine may utilize a block to determine the width of a mortise in a plate in which the block is to be placed and secured, I provide the attachment T. (Shown in Fig. 4 of the drawings.) The said attachment comprises a slide-block shaped in conformity to and arranged in the groove of the slide J and having a transverse groove a and also having a threaded post I) rising from the bottom of said groove, a nut 0 mounted on the threaded post, and a bracket-arm d havin a bifurcated portion straddling the threade post and arranged in the groove (i of the slide-block, whereby it is held against lateral wabbling or play and interposed or clamped between the nut and the slide-block, and also having a depressed portion a provided in its longitudinal center with a raised rib f It will be observed that when a block is placed on the depressed portion of the bracket-arm d and is interposed between the rib f 5 and the adjacent edge of the carriage H and the nut c is tightened and the block removed the rib f 5 will, when it brings up against the said edge of the carriage, stop the movement of the slide toward the right, and thereby as sure the production in a plate of a mortise corresponding in width to and adapted to snugly receive the said block,

The carriage I at the left of the machine is similar to the carriageH in that it is equipped with brackets L, a gage M, and plate-clamping means like those of said carriage II, and also in that it is adapted to be moved forwardly and rearwardly, so as to carry a plate to be mortised into and out of engagement with its complementary cutter D. Said carriage I, however, differs from the carriage H in that its bar J is not a slide-bar, but is fixed with respect to it, and hence has no longitudinal movement. From this it follows that the carriage I and its appurtenances are designed for the class of work in which the width of the mortises is deterr. ined by the width or thickness of the blades of the cutter.

type or other late through the medium of It is obvious, however, that the said carriage 05 the left walls of the notches c and e of gage I might be equipped with all of the appurten'ances common to the carriage H without involving a departure from the scope of my invention.

As will be gathered from the foregoing, my invention contemplates the operation of the carriage II and its appurtenances by one workman and the operation of the carriage I and its appurtenances by another workman, and also contemplates the employment of the portion of the table B intermediate the carriages H and I as a support for the plates. In order to enable either workman to cut off electric current from the electric motor, and thereby stop the shaft 0 when necessity demands, I provide the switches M at the front of the main frame and below the carriages II and I.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the said embodiment. I do not desire, however, to be understood as confining my self to such specific construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.
