GEORGE J. l). RODIVELL, OF BUFFALO, NEW YORK, ASSIGNOR OF TWVO- THIRDS TO SAMUEL J. MOORE AND HER-BERT O. SEOORD, OF TORONTO,
SPECIFICATION forming part of Letters Patent No. 511,215, dated December 19,1893. Application filed February 11, 1898. Serial No. 461,948- (No model) To aZZ whom it may concern:
This invention is designed for applying ink to pads used for inking marking stamps and analogous articles.
My invention consists in an improved con-" struction and combination of the component parts of the pad inker, said parts being readily stamped out of sheet metal, and struck up into shape by means of suitable dies, and readily united to form a pad inker of great eliiciency and convenience of operation, all as hereinafter more fully described and set forth in the claim.
In the annexed drawings Figure l is a vertical transverse section of a pad-inker embodying my invention. Fig. 2 is a top plan View of the same. Fig. 3 is a transverse section on line as, it in Fig. 1. Fig. 4; is a side-view of an inker designed for use on pads-having the stamp connected to them, a part of the side of the discharge pipe being broken away to illustrate the internal parts thereof, and Fig. 5 is a sectional view of a modification of the spring which holds the valve in its closed position.
Similar letters of reference indicate corresponding parts.
R- represents the ink-fount which I preferably form of sheet metal and of cylindrical shape. To one end of this cylinder I solder or otherwise firmly secure a plate i which constitutes the bottom of the fount. The center of this bottom plate is provided witha circular opening -o-- through which to introduce the ink. Said openingis screw-threaded and closed by a correspondingly screw-threaded plug or stopper -a removably secured therein. p
In the upper end of the fount -R- I fasten in any suitable manner the ring -b-- which is formed with the inward ofiset -19- and upward flange bas illustrated in Fig. lot the drawings. To the under side of this offset I solder the disk c which is formed with the upwardly or outwardly ex-- tending discharge-tube -i-, in its center.
The inner end of this tube I preferably form flaring to facilitate the egress of the ink when desired. Beneath the disk ois a spider eattached to the ring b as shown, or to the innerside of the cylinder -R as may be desired. This spider is provided with a central orifice for the purpose hereinafter explained.
cldenotes a valve which is seated on the under side of the disk cand, when the discharge tube t is made flaring as aforesaid, I form the said valve conical. The valve has a stem d' extending from its top up through the tube t and projects above said tube when the valve is closed. To properly guide the valve I provide it with a downwardly extending stem t"- which passes through the central orifice of the spider e. A spiral spring is interposed between the spider and valve to hold the latter in its closed position.
The hereinbefore described flange b"- and tube -t form an annularcup surrounding said tube, and in this cup I secure a swab or brush h composed of felt or other suitable material adapted to spread over the pad the ink issuing from the tube 15.
In using the described inker it is to be placed in an inverted position upon the pad to be inked. The bearing of the outer end of the stem d upon the pad pushes the valve cZ into its open position and thus allows the ink to escape through the tube t. Then, by wiping the pad with the inker inverted as aforesaid, the swab h spreads the ink over the pad. As soon as the inker is removed from the pad the valve -d is automatically closed by the spring -f.
hen the inker is to be used on pads connected to the stamp, as is the case with spring stamps, where the pad is not accessible by an inker of the form shown in Fig.1 of the drawings, I provide the fount R with a spout -R'- which terminates with a lateral projection to which I connect the discharge tube t-, swab h and valve dcombined and operating similar to the corresponding parts shown in Fig. 1 of the drawings.
I do not wish to be limited specifically to the use of the spiral spring fas it is obvious thatother forms of springs may be employed for the same purpose. One of said modifications is illustrated in Fig, 5 of the drawings, in which the spring fis formed of a leaf or plate of steel or other suitable spring metal bowed at its central portion and secured at one end to the under side of the disk --c-- and supporting upon its opposite end the valve d.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, isr- As an improved article of manufacture, a pad-inker composed of the fount -R-- provided with the removable stopper a in its bottom, the ring 'bsecured to the upper end of said fount and formed with the inward offset -b--' and upward flange b, the disk c secured to the said oifset and formed with the upwardly extending tube t, the valve dseated on the under 7 side of the disk and provided with the stem d extending through the tube -t-, the
spider e attached to the ring -h, the stem --t"- extending from the valve through the said spider, the spiral spring -'-finterposed between the spider and valve, and the swab hseated upon the disk c--rand confined thereon by the tube -tand flange -b", substantially as described and shown.
In testimony whereof I have hereunto signed my name this 18th day of January,
