PRINTING-STAMP.

SPECIFICATION forming part of Letters Patent No. 766,853,` dated August 9, 1904.

i Application filed August 12, 1899.

To a/ZZ whom ima/y concern:

Be it known that I, LIBANUs M. TODD, of Rochester, in the county of Monroe and State of New York, have invented certain new and. useful Improvements in Printing-Stamps; and I do hereby declare the following to be a full,

clear, and exact descriptionof the same,- reference beingA had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My invention has for its object to provide an improved .printing apparatus or stamp particularly adapted for marking or embossing upon checks, drafts, and similar instruments words or figures indicating a limiting amount beyond which such instrument is not good; and it consists in certain 'improvements,'here inafter fully described, whereby not only is the construction of the device simplified, but the operations necessary to effect the marking ofv the check may be readily accomplished and the marking surfaces or forms'readily changedto bring one or the other of the series contained on` the printing-wheel in position for printing, all as will be hereinafter described, and lthe novel features pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a side elevation Of a printing-stamp constructed in accordance with my invention; Fig. 2, a sectional view taken on the line mw of Fig. 3; Fig. 3', a longitudinal sectional view taken on the line y y of Fig. 4.; Fig. 4, a bottom plan view with the bottom of the casing removed.

Similar reference-numerals indicate similar parts.

The maincasing 1 of the machine is preferably composed of a single casting having the forward rounding portion for containing the printing-wheel and open at the bottom, said opening adapted to be closed or partially closed by a base piece or block 2 of wood or other- J ust beneath the .rounding portion of the casing is formed aslot or passage 3, preferably formed by sawing through the casing ,and adapted for the entrance of a check,

draft,`or other instrument in position to be printed upon. J ournaled in the casing is an .arbor or shaft 4,upon which is mounted a Serial No. 727,052. (No model.)

printing-wheel 5, preferably secured in posit1on bya screw 6 and having at lts periphery a series of notches or recesses in which are secured a series of printing-forms 7, composed of a stereotype-block or line of printing-type 9, by means of which the printing-wheel may be rotatedto bring any of the numbers upon the dial 8 into cooperative relation with a suitable index 10 on the main frame. -The coincidence of thefigures with the index indicates lthat the printing-form corresponding to the gures is on the under side in proper printing position. This printing-wheel is freely rotatable and is centeredor yieldinglyl held in proper position with the printing-form directly above the cooperating platen, presently described,

by means of. a suitable centering device, in the i present instance consisting of a felt-covered rollel` 11, mounted upon an arbor 12, supported upon and pressed toward the center of the printing-wheel by spring-arms 13, as shown particularly in Fig. 3, the typefor'ms or -blocks constituting the necessary projections on the wheel or carrier. This felt-covered roller contains ink upon its surface and not only serves to center the printing-wheel by the `movement toward the arbor 4 and between,

`the printing-forms 7, as described, but also "serves to'apply ink to the surfaces of the type during the rotationV of the wheel in either di- "rection.

Located in the base of the main frame is a movable platen 16, preferably provided in its upper surface with a rubber, leather, or other suitable yielding block 17 and secured to `or l formed with arms 18, fitting insockets se'- cured to or sleeved upon an oscillatory arbor 19, mounted in the frame, as shownin Figs. 3 and 4. This platen 16 is normally in adepressed position, as shown infull line'siiny Fig. 3, with the pad 17 directly beneath'rthe center of the printing-wheel, so that a check or other instrument maybe introduced between the platen and printing-wheel, and the former may be moved up to press the paper into contact with the type-form, the yielding pad in the platen serving to make a good impression and depending upon the force exercised, causing the type-form to more or less emboss or indent the paper, so that as the fibers are stretched the ink may sink into the paper` and prevent ready erasure. In the present embodiment the means for elevating the platen consists of a lever 21, formed as Shown particularly in Fig. 4, pivoted upon an arbor or shaft 22, secured in the sides of the main frame by a screw 2O or otherwise, and having on its shorter end or ends lugs. or abutments adapted when the rear end of the lever is pressed down to engage with the under side of the platen 16 or, preferably, small inclined surfaces 23 thereon to raise said Aplaten and bring the paper into contact with the'printing-form. In the present embodiment the lugs are inthe form of adjustable screws 211, so as to permit the greater or lesser elevation of the platen, as may be desirable or necessary, and the surfaces 23 on the under side of the platen consist of hard-metal balls 14, arranged in sockets formed in the latter and held in place by compressing or upsetting' the metal of the platenbeneath them to prevent their accidental removal, but without preventing their free rotation in the sockets, thereby reducing the friction between 4the parts, or, ifdesired, the balls may be made stationary, simply affording hard smooth surfaces in which point contact only is had. The rear end of the lever 21 is slotted both vertically and horizontally, as shown, and in the horizontal slots 25 is arranged a pin 26 on a plunger 27, vertically movable through a suitable adjustable sleeve or collar 16 on the casing and also through a lug 2() formed in the latter. The upper end of the plunger is provided with a slot 30, in which operates a pin 31 on a lever or handle 32, pivoted at 33 to a bracket 34 on the casing and having the broad forward end 35. The handle is held in raised position by a spring, such as 36, whereby the platen is allowed 'to fall to its lowest position, as in full lines in Fig. 3. Interposed between the lever 32 and the top of the adjustable stop or sleeve 16 is a buffer or washer 37, serving to arrest the handle or plunger, and as the stop is adjustable the amount of force exerted in printing or stamping may be regulated as desired. While I prefer to employ the lever, it is not absolutely necessary, as a handle could be applied directly to the end of the plunger; but I prefer the lever, as it increases the power.

The operation of the device will be readily understood from an inspection of the drawings. The operator desiring to cancel or mark a check places the latter in the'slot 3 in the main casing, moving it up against an adjustable stop 42, held by a set-screw #13. lle then operates the handle 9 of the printing-wheel until the desired character on the dial is brought into coincidence with the index 10. Then he strikes a sharp blow upon the end of the lever, moving the platen and check up against the form on the printing-wheel, as will be understood. After the wheel 5 has been adjusted with the proper character approximately in line with the index 10 the inking-roller 11 will serve to center it, as before described, and during the rotation of the wheel the proper amount of ink will be applied to the printing-forms.

The printing-forms upon the wheel 5 may be removed or changed, if desired, or the whole wheel may be removed by withdrawing the arbor, lirst loosening the screw 6, when the head of the latter is accessible through the bottom of the casing.

By making the main frame of a single casting, as shown, not only are the parts well protected, but 1 insure simplicity of construction and give the whole device a neat and substantial appearance.

I claim as my invention-- 1. In a printing apparatus, the combination with a support, a freely-rotatable printingwheel mounted on an axis journaled in the frame and having projectingprinting characters, of a yielding centering device movable radially of the printing-wheel and engaging between the type characters to center them and hold the wheel in printing position, a platen movable toward and from the wheel and means for operating it.
