Specification of Letters Patent. Patented July 26, 1910.

Application filed. July 6, 1909. SeriahiNo'. 506,219.

To all whom it may concern:

Be it known that I, FREDERICK MEYER, a subject of the King of Great Britain and lreland, residing at Liverpool, England, have invented a certain new and useful Improved Means for Detaching from the Sheetand Atlixing Postage-Stamps, and the Like, of which the following is a specification.

The object of my invention is to effect in an improved manner the separation or do tachment of postage stamps, labels and the like from the customary gummed and perforated sheets, and the affixing of the same when required to postal matter or to any desired object, and the invention consists in an improved machine of the kind having a carriage or movable or traveling table which carries the sheet of postage stamps labels or the like, hereinafter referred to as stamps, in the form of a roll.

Any number of the ordinary perforated sheets of adhesive stamps can be made into one continuous roll by a very simple process, and there is practically no limit to the number of stamps with which this machine can thus deal continuously.

With the exception of depressing the main ever, the machine acts automatically. The roll of stamps is suitably supported in juxtaposition to a device for feeding the sheet automatically toward special knives which shear the stamps from the sheet. This feed ing device consists of a number of needle points placed accurately between disks cut and prepared to carry the correct'number of points, (alternatively the points can be formed by any other approved method). These points engage the perforations of the stamps, giving an exact length of forward movement to the sheet, and at the end of the travel of the movable table the disks carrying the needle points are automatically turned to the next position by means of mechanism connected to the main lever and stamping rod, thus carrying forward the sheet of stamps and causing a cross row of perforations to lie directly under the knives for continuing the operation on the next row of stamps. A tappet action is employed for working this mechanism, and a means for preventing overthrow is attached.

The special knives, which have a positive motion when cutting through the perforated edges of each stamp which connect it to the sheet, are released on their downward stroke at a given point, and by means of springs regain their position after cutting or detaching the stamp from the sheet, thus allowing the stamping rod to complete its stroke and affix the severed stamp. A movable stripper surrounds the knives to prevent any dragging of the sheet during the cutting loose of the stamps; the same serving also to guide the stamps under the knives.

The severed stamps are caused to adhere to the matter to be stamped by means of a clamping device consisting of a licker of felt or other suitable material attached to a lever arm and worked automatically by means of the stamping rod or main lever. This licker takes its moisture from a roller of pumice stone or other-suitable material, which roller absorbs the moisture from a trough or tank. The licker as it returns to its normal position turns the roller, being thus equally moistened at every stroke. The licker can be made suitable for applying the moisture to the matter to be stamped, or to the gummed side of the stamp, as preferred.

The position of the licker before the stamping rod is depressed is such that it is resting against the absorbent roller, which roller is always impregnated with moisture While there is water in the trough or tank. Thus, at each stroke of the stamping rod this licker gets just enough moisture to cause the severed stamp to adhere to the matter to be stamped.

The travel of the sheet carrying table and the movements of the sheet of stamps thereon take place during the upward strokes of the stamping rod and main lever.

The movable. table is fed in either direction by means of racks attached to the underside of the same, and cut in opposite Ways, and the pawls actuating the racks are alternately thrown in and out of mesh at the respective ends of the travel of the table. The racks are attached to the table by means of bolts which work in a slot at each end of the rack, so as to allow the carriageto be stationary at each end of its travel for one depression of the main lever. This allows the next row of stamps to be fed forward before the table is moved in the reverse direction. On the completion of the travel of the table in one direction the racks themselves move in the reverse direction, but owing to said slots in the racks this action does not move the table. The table is automatically locked at each stroke of the main lever and stamping rod by means of a tooth working in a rack which is cut to an exact register.

The upper surface of the piece of mail matter or other article to be stamped is always brought into the same plane and position by means of a plunger which automatically rises and presses the same toward the stamping rod upon the first downward movement of the main lever, and upon the stamping rod continuing its stroke after cutting loose the stamp, this plunger is again pressed down into its original position ready for the next depression of the main lever.

In the drawings annexed hereto: Figure 1 is an elevation; Fig. 2 is a plan and Fig. 3 is an end view of my improved machine; Fig. 4 is a plan of the machine with the movable table removed, showing the mechanism for working it; Fig. 5 is a sectional end view showing the mechanism for working the movable table and plunger; Fig. 6 is an enlarged back elevation showing the stamping rod, knives and stripper; Fig. 7 is a side elevation projected from Fig. 6; Fig. 8

represents an enlarged sectional view, corresponding as to plane with Fig. 5, and showing additional parts; Fig. 9 is a fragmentary top view of the licker and its appurtenances on the same scale as Fig. 8; Fig. 10 is an elevation projected from Fig. 9; Figs. 11, 12 and 13 are respectively front, side and top views of the knife or knives, detached, and Fig. 14 is a fragmentary end view partly in section showing one of the parts represented in Fig. 3 in its effective position.

Like reference characters refer to similar parts in all the figures.

My machine can be made of any desired shape and constructed of any suitable material, and if necessary can be fitted with bal bearings of an ordinary type.

Attached to a stationary frame, A, containing a movable horizontal table, B, carried upon guides, B, is a vertical stamping rod, C, which is carried by means of guides in a bracket, D, and is worked by a hand lever, E, herein termed the main lever. The bracket D can be cast on or otherwise fixed upon the stationary frame A, in any desired position. Working in the same, atthe stamping rod C, are knives, FF shown detached by Figs. 11-13. These knives can be made of any desired shape and thickness and are reduced at the lower end to form a cutting edge, 7, Figs. 11 and 12; this cutting edge being suitably shaped and proportioned to detach or sever the stamps from the sheet along the customary lines of perforations, upon the depression of the stamping rod by means of the main lever E.

The knives F F 3 are connected to a pair of superjacent pivoted arms G, by means of pins F; these pins being placed in a given position 011 the two side knives F. .A third knife, F is attached to the two side knives by means of a lug and notch locking arrangement, F thus forming three sides of a rectangular tube.

Upon the depression of the main lever E, a stud, C, Figs. 6 and 7, on each side of the stamping rod C, engages with a projection, G Fig. 7, on each of the arms G, thus forcing the knives downward. After the arms G travel a given distance, a projection, G Fig. 7, on each arm is forced against an opposing projection, D, on the bracket D; these projections being formed of such a shape as to cause the arms G to push themselves away from the upright position as they travel downward, and, by means of springs D Figs. 6 and 7, immediately the arms G are pushed far enough out of the perpendicular, to release their shoulders G from the stamping rod C, the arms G with the knives FF'- attached after cutting loose the stamp at its perforated edges, spring back into their elevated positions, and allow the stamping rod C to continue its stroke independently, for attaching the severed stamp.

At a 'iven point the main lever E interacts wit a rocking spindle H, Figs. 1, 2 and 3, carried by a bracket, H, or by any suitable means. Attached to this spindle is a lever arm, K, Figs. 2-5 and Fig. 8, carrying a projection, K, and a pin, 1' The latter interacts with one end of a. pitman, L, the other end of this pitman being attached to a three armed lever, M, (or an equivalent disk,) best shown in Fig. 1, which carries a pair of pawls, M and M Upon the main lever E being depressed, it moves upon the rocking spindle H as a center, and forces the lever arm K outward, and by means of the pitman L connecting this lever arm K to the lever M, this lever M is turned a given distance, which allows its pawl M to engage an opposing tooth of a double rack N attached to the bottom of the table B. Upon the upward stroke of the stamping rod C and main lever E, this pawl M pushes the rack N and table B forward, and brings the next stamp into position beneath the stamping rod G for continuing the operation. The rack N is attached in a desired position on the movable table B by means of vertical bolts, 1 and 2, Fig. 4, passed upward through a longitudinal lostmotion slot at each end of the rack N for the purpose of allowing the rack to move without moving the table during the upward stroke following the last depression of the main lever E for each row of stamps, so as to allow the sheet of stamps to be fed forward while the table remains in the same position as during the previous cut.

The rack N is shown in the accompanying drawings as a double rack having both sides cut with teeth. It maybe an advantage to have the rack made in two pieces, with one set of teeth out in each rack piece.

On the respective sides of the rack N are springs, O and 0, Fig. 4 and Fig. 8, which serve as guides for the pawls iv and M Upon the sliding carriage coming to the end of its travel in one direction the pawl M will force its way clear of the guide spring 0 and will return on the outside of this guide spring 0, which will keep it from meshing with the teeth on its side of the rack N. Also upon the end of the same direction of travel the pawl M will drop into position for reversing the travel of the table by falling over the end of the guide spring 0 and engaging with the teeth on the same side of the rack N. The pawls M and M are fitted with small springs 011 the underside to keep them always inclined toward the teeth of the rack N for keeping them in mesh therewith.

Attached to the underside of the movable table 13 is a device for locking'the table in position at each stroke, consisting of a looking rack R, Figs. 4, 5 and 8, cut to an exact register, with reference to the longitudinal rows of perforations in the sheet of stamps, and working in the teeth of this rack is a tooth P carried by a lever P. This lever P is pivoted to the stationary frame A, and is kept toward its work by a spring P. Upon the lever M is a projection, M made of such a shape that when the lever M is regaining its original position upon the upward stroke of the main lever E, this pro jection M engages a projection S (Fig. 4) on a lever S (which lever is attached to the lever P by means of a pivot) and releases the locking tooth P on the lever P from the teeth of the locking rack R, thus allowing the carriage to move to the proper position for detaching the next stamp, when the tooth P again springs into an interdental notch of the locking rack R, and locks the table in position until again, upon the upward stroke of the main lever E, the operation is repeated. i

A spring E, Figs. 3 and 5, stretched from the stationary frame A, provides for bringing the main lever E back to its original position after detaching each stamp, from the sheet.

In the stationary frame A a spring elevated plunger, T, Figs. 4c, 5 and 8, is placed directly under the stamping rod C. This plunger T is released immediately upon the downward movement of the main lever E,

and serves to bring the upper surface of the article to be stamped into the desired plane. In this operation the lower end of the lever K coming into contact with a peculiarly shaped movable detent U, forces the same back and thus releases the plunger, when by means of springs T interacting therewith, the plunger is forced upward and carries therewith the article to be stamped to the desired plane. A pair of interacting cam projections, 3 and 4-, Fig. 8, carried by the frame A and the detent U respectively, limit the retracting of the detent to the required extent by depressing the latter at the proper moment so that its upturned end, 5, Fig. 8, ceases to interact with the lower end of the lever arm K until it is reelevated. The plunger T is forced back again to its original depressed position in which it is shown in Figs. 5 and 8, by the stamping rod C when the latter is pressed down for attaching the stamp, and thereupon the detent U is returned to its normal position by springs, UT and U and holds the plunger T in its sald orlglnal position till the main lever E is again depressed, for continuing the operation.

Upon the stationary frame A, is placed in a desired position a trough or tank V, Figs. 1, 9 and 10, supplied with a moistening device V, Figs. 9 and 10, which may consist of a roller of pumice stone or other suitable porous material, arranged to interact with a damping licker G This tank V is so constructed that the fluid does not easily spill when in operation, and can be made as an ordinary covered in or foursided trough of any desired length. The position on the frame A is such, that when the damping licker C returns to its original position (Figs. 9 and 10) upon the upward stroke of the main lever IE, it touches the roller V and turns it a certain distance, thus getting a little moisture at each stroke of the main lever E.

At a 'iven position the stamping rod 0 is provided with a pin, C Figs. 6 and 7, which works a two-armed lever C C, Fig. 1, etc., connected to a pitman, (1, which in its turn is connected to the lever arm of said licker C (See Figs. 9 and 10.) This lever arm works upon a fixed horizontal pivot pin, C, and is set to such a radius that when in action the licker moistens the upper surface of the article to be stamped to the desired extent. Upon the depression of the main lever E the stamping rod C actuates the lever C G which in, its turn moves the licker G and the lever arm of the latter, working on a pivot pin G, de

termines the radius of its movement. The licker moistens the article to be stamped immediately before the. stamp is detached from the sheet, and aflixed by the stamping rod C continuing its stroke to the end.

Connected to the lever arm C is a small pitman C Figs. 1 and 2, for working a counter, C, for the purpose of registering or recording the number of stamps or the like used, and which can be arranged as shown or in any other suitable manner.

A convenient space, WV, Fig. 1 etc., is left under the tank V, and under the stamping rod C to receive the article to be stamped.

A movable stripper, A (Figs. 6 and 7) surrounds the knives F--F for keeping the stamps in position while being detached, and is released at the same time as the knives, and springs back into position under the tension of springs, A ready for the next operation upon the depression of the main lever E.

The movable table B is of suitable size to carry a sheet of stamps of given Width, and is carried upon brackets or guides, B, Figs. 2, etc, and can be run with or without ball bearings. On the underside of the table and fixed thereto I arrange the locking rack R the traveling rack N and the guide springs O and O heretofore described. Upon the upper side of the table is fixed the device for feeding the sheet of stamps toward and under the knives FF of the stamping rod G.

The device last mentioned includes a spindle, Y, Figs. 13 and Fig. 8, carried at each end by means of brackets Y resting upon the movable table B. These brackets can be fixed to the table or can be made to work from a center and form a lifting arm for a readier means of inserting the first row of stamps. Upon the spindle Y, at each end are fixed disks, Y containing needle points, 6, Fig. 8, placed at regular distances, accurately, so as to work into parallel rows of the perforations of the sheet of stamps. Fixed to each pair of these disks is a ratchet wheel, Y' and outside of these ratchet wheels Y are placed shaped disks, Y carrying pawls, 7, Fig. 8, for turning the ratchet wheels Y. The disks Y are loose on the spindle Y. A toothed wheel Y is also fixed to this spindle Y on each end;

- also on one end is fixed a thumb wheel, Y

and on the other end is fixed a toothed wheel, Y with a detent spring Y", for holding the same in its angular positions. Upon the table B I further arrange two slides, B and B Figs. 2, 3 and S, pivotally coupled to the pawl carriers Y Attached to these slides B 13*, by means of pivot pins, B Fig. 2, are movable pieces, B B Figs. 2 and 3, which are in turn connected to the table by springs B B.

The sheet of stamps is adjusted by hand so as to engage the needle points of the disks Y and these feeding disks are then turned by means of the thumb wheel Y until the stamps of the first row of stamps are in correct position for detachment successively from the sheet. Upon the last stamp of the row being detached by the downward stroke of the stamping red C and main lever E, then upon the next upward stroke of the main lever the projection K on the lever K pushes forward the slide B or B that is then in juxtaposition to said projection K, and such slide B or 13*, by means of the interacting pawl carrier Y and ratchet wheel Y turns the spindle Y and needlepoint disks Y a certain distance, and thereby feeds the sheet of stamps into position for detaching the next row from the sheet. The slide B or B" when it is pushed forward carries with it the attached movable piece or B which engages with the corresponding toothed wheel Y, as in Fig. 14, and forms a locking arrangement to prevent overthrow. Upon the next stroke of the stamping rod C and main lever E said slide 13 or 13* escapes the projection K on the lever K, and is returned to its normal position by means of the interacting spring B or B", and, owing to the pawl carriers Y being loose on the spindle Y, the sheet of stamps remains in correct position. Upon arriving at the end of the new row of stamps like action takes place with the other slide (13 or B in action; the two slides 13 and B being operated alternately. The small cut wheel Y and spring Y are for keeping the spindle Y in position after each locking operation. The thumb wheel Y is for turning the spindle by the direct application of the hand for setting the first row of stamps in the correct position for detachment from the sheet.

A. roller, X, Figs. 13 and Fig. 8, carried by brackets X is placed on the movable table B to carry the sheet or any number of united sheets in roll form, and the sheet is led around a leading roller, X Fig. 8, to keep the same tight when the knives are shearing off the stamps.

The method of working the machine is as follows:-The continuous sheet of stamps, is placed on the roller X and adjusted as above described, and the water or other suitable damping material is placed in the tank V for moistening the licker C which dampens the surface of the articles to be stamped. An operator then depresses the'main lever E, and by this action, a stamp is sheared from the sheet by cuts coincident with the perforations along its two attached edges, and is then carried downward and affixed to said damped surface. Upon the upward stroke of the main lever E the carriage B is automatically moved into the correct position for severing the next stamp, and this action continues until the end of a row of stamps is reached. The next row of stamps is then automatically fed forward by means of the feeding-in device, and the operation is thus continued.

In my claims hereto appended the terms stamp and stamps will, as hereinbefore used, include label or labels and the like; and the term sheet will include any number of commercial sheets united so as to follow one another continuously.
