STAMPING-MACHINE.

EPECIFICATION forming part of Letters Patent No. 658,672, dated September 25, 1900.

Application filed January 30, 1900. Seria1No.3,358- (No model.)

To (11M Lu/tom, it Duty concern:

Be it known that I, CHARLES M. PIERCE, a citizen of the United States, residing at WVeston, in the county of Umatilla and State of Oregon, have invented a new and useful Stamping-Machine, of which the following is a speciiication.

The invention relates to improvements in stamping-machines.

The object of the present invention is to improve the construction of stamping-machines and to provide a simple, inexpensive, and efficient one designed for use in banks, railroad-offices, post-offices, and the like, and capable of being rapidly operated by either the foot or hand and of automaticallyinking itself after each operation.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings, Figure 1 is a perspective View of a stamping-machine constructed in accordance with this invention and arranged to be operated solely by hand, the stamp being in engagement with the table. Fig. 2 is a side elevation showing the stamping-machine constructed to be operated either by hand or foot, the stamp being in engagement with the ink-pad.

Like numerals of reference designate corres pending parts in both figures of the drawings.

1 designates a base, from the rear portion of which rises a short upright or post 2, having its upper end bifurcated and receiving the angle of a bell-crank lever 3, which is fulcrumed on a pivot 4. The bell-crank lever is provided with a short rearwardly-extending arm 5, which is connected with a coiled spring 6, and it has a long upwardly-extending arm 7, which is connected with a longitudinally-movable bar 8, that carries a stamp 9. The coiled spring 6 is secured at its lower end to the base, and it is adapted to be distended, as illustrated in Fig. 1 of the accompanying drawings, when the stamping-inachine is operated and when the stamp is in engagement with a table 10, whereby the stamp will be returned to its normal position when the operating mechanism is released. The upper end of the arm 7 of the bell-crank the links 12 are connected with the upper end of the standard, the width of which is reduced by means of a transverse bolt 14 or other suitable pivot, and the upper ends of the links are pivoted to opposite sides of the bar 8 by a pin 15 or other suitable pivot. When the device is operated, the links oscillate from the position shown in Fig. 2 to that illustrated in Fig. l, and the spring 6 serves to return the links after the device has been operated by the means hereinafter described.

The stamp preferably consists of a head provided at its lower face with suitable characters and having an extension 16, arranged between two parallel members 17 of an adjustable clamp, which is mounted on the laterallyextending arms or portions of the T-shaped bar 8. The members of the clamp consist of short plates or pieces bolted or otherwise secured to the opposite faces of the extension 16 of the stamp and provided at their rear ends with openings 18, through which the laterally-extending arms of the bar 8 pass. The members are provided at the top walls of the openings with threaded perforations for the reception of set-screws 19, whereby the members are secured at the desired adjustment, the screws being adapted to engage the said laterally-extendin g arms. The plates or members, which are perforated for the reception of suitable fastening devices for securing them to the stamp, may be fastened to the ends of the stamp and stamps of any size may be applied to the members of the clamp; also, the members are capable of adjustment to position the stamp over difierent portions of an inkpad 20.

The ink-pad 20, which may be of any desired constrnction,is located in rearofa table 10 and may be supported by an extension thereof, as illustrated in the accompanying drawings,

The table,which is shown in the accompany ingdrawings asataperingortriangular block, is provided at its upper face with a cushion 22, of felt or other suitable material, to avoid injuring the type of the stamp. The inner end or apex of the block is cut away or recessed at the top to form the shelf 21, which is inclined, asillustrated in the accompanying drawings.

The bellcrank lever is oscillated by an operatinglever 23, loosely fulcrumed in a slot or bifurcation of a post 24 and having its rear portion bent inward at right angles and provided with a perforated ear which is pivoted to the short arm of the bell-crank lever. The front purl ion of the lever is extended outward laterally at 25 and is provided with an approximately L-shaped handle portion 26, extending forward and arranged within con venient reach and adapted to be depressed to operate the stamping-machine. As soon as the o .)erating-lever is released the spring will return the parts to their normal position. A treadie 27 may be connected by a rod 2a with the operating-lever to enable the device to be operated by foot-power, and when the treadle is employed the rod is preferably extended through the base, as indicated in Fig. 2 of the drawings. By loosely fulcruming the operating-lever in the bifurcation of the post 24 it is permitted the limited longitudinal movement incident to the oscillation of the short arm of the bell-crank lever.

It will be seen that the stamping-machine is exceedingly simple and inexpensive in construction, that it is adapted to be quickly operated, and that it may be employed advantageously in banks, post-otfices, and railroadoifices and analogous places where a large amount of stamping in a comparatively short time is necessary.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What is claimed is 1. In a machine of the class described, the combination of a support, a longitudinallymovable bar connected with the support and provided at its front end with laterally-disposed arms, mechanism connected with the longitudinally-movable bar for actuating the same, the forwardly-extending clamp members having openings to receive the laterallyextending arms and provided-with means for engaging the same, whereby the clamp members are adapted to be adjusted toward and from each other, and a stamp secured between the clamp members and located in advance of the longitudinally-movable bar, substantially as described.

2. In a machine of the class described, the combination of a base having a fixed support to receive the work, a standard, a longitudinally-movable bar extending in advance and in rear of the standard and connected at a point between its ends with the standard by a link, a stam p located in advance of the standard and connected with the front end of the longitudinally-movahle bar, the bellcrank lever fulcrumed at its angle in rear of the standard and having its front arm elongated and connected with the rear end of the longitudinally-movable bar, and a lever arranged approXimat-ely parallel with the longitudinally movable bar and loosely fulcrumed between its ends and having its rear end bent laterally and pivoted to the rear arm of the bell-crank lever, and a spring connected with the latter, substantially as described.

3. In a machine of the class described, the combination of a base, a fixed block mounted on the front portion of the base and adapted to receive the work, a standard rising from the base in rear of the block, a longitudinallymovable bar extending in advance and in rear of the standard and connected at a point between its ends with the standard by a link, a bell-crank lever fulcru med at its angle in rear of the longitudinally-movable bar and having one of its arms elongated and pivoted to the said bar, a post having a slot or bifurcation, and an operating-lever loosely fulcrumed in the slot or bifurcation and extending longitudinally of the machine and having its rear end bent at an angle and pivoted to the bellcrank lever, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

CHARLES M. PIERCE.
