SPECIFICATION formingpart of Letters Patent No. 759,218, dated May 3, 1904.

Application filed November 3,1902. Serial No. 129,898. (No model.)

To all whom it 10Q/ay concern,.--

Be it known that I, J AMES MILLER, a citizen of the United States, residing' at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Printing-Stamps; and I declare the following' to be a full,clear,and exact description of the invention, such as will enable others Skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speci- Iication.

This invention relates to printing-stamps, and has for its object an improved stamp that is adapted to be held on the thumb or iinger ofthe operator and is arranged to bring an inl ingpadinto contact with the type part of the stamp automatically between successive impressions.

The device is one which is especially useful for those who are handling' large numbers of articles on each of which it is desired to impress some indicating' charaeter,and the stamp is arranged to produce an imprint on the article as soon as the article is taken into the For this purpose it is arranged to be attached to the end of the thumb or to the end of the iinger, and that part of it which is provided with the type by which the imprint is made is placed immediately in front of the grasping part of the iinger or thumb, so that the imprint is made by pinching the article between the opposing digit and the digit that is provided with the stamp.

In the drawings, Figure 1 is a perspective oi' the device. Fig. 2, consisting of the parts 2 and 2, is a perspective showing the parts in detail and on a scale somewhat larger than the actual device. Fig. 3 is a side elevation with the front casing removed, and this shows more particularly the swinging ink-pad.

2 indicates a ring of a size suitable to be placed on the end of the thumb o1' the end of the iinger. A frame-piece, part of which, 5,

arches around the ring, and arms of which, 3 and 4, project tangential to the curve ot' the arched piece 5 form part of a frame which 1s completed by pieces 6 and 7, that are secured to the sides of the ring and at the ends of a diameter thereto. The arm?) forms with the tangential frame-piece 6 a rectangular boxlile structure,in which there engages slid ingly the branch 8 of a guard composed oi two branches 8 and 9 and the cross-plate l0. The branch 9 engages similarly in the box-like structure formed by arm4 and piece 7. The guard is arranged to have a sliding Inotion with respect to the box-like 'frames and is prevented I'rom escaping therefrom in any suitable way, but is normally held out to the eX- tent of its outward motion by springs 11, each of which is secured to one of the frames and engages behind a pin that projects through a slot in the guard-arm. The pin 12 is a crank-pin on a swinging lever 14, that is pivotally secured by pivot l5 in the box struc'- ture 6, and the spring 1l tends to hold the lever 14 to the position shown in Fig. 3.

There is in the box structure composed of the branch 4 and the frame-piece 7 a lever similar in all respects to the lever let, provided with a pin which is similar to the pin 12, and this engages through a slot similar in all respects to the slot 13. When the sliding meniber 8 9 10 is pushed inward, that part of it which engages with the pin 12 actuates the lever and swings it on its pivot 15. The two levers 14 and its companion are joined by a cross-bar 16, which is'provided with an inkpad 17.

On the body of the ring 2, extending toward the pad, is a type-holder 18, and this holds a type with the extreme outer end projecting through an opening 19 in the plate l0 when the plate 10 is pushed inward; but the extreme outer end of the type is covered by the pad on the cross-bar 16 when the levers are swung by the force of the spring, which contemporaneously swings the levers and projects the guard.

The pivot 15 of the lever 14, which carries the pad-support, projects from the side piece 6, (and the companion-pivot projects similarly from the side piece 7 The cross-bar which carries the pad swings from a pivot which remains constant with respect to the 'face ot' the type and swings clear of the face of the type; but the pad 17, carried by the cross-bar, is forced to wipe across the face of the type under compression suficient to furnish to the face of the type the necessury supply of ink and on its retreat to wipe off any surplus of the ink. The inliing-pad swings in the space underneath the ends of the side pieces 6 and 7 and between the sides 8 and 9 and the crossplate l0, as indicated in dotted lines in Fig. 3, and these parts form a housing for the inkpad and the type, in which the ink-pad is always confined and protected from accidental contact with the articles upon which the imprint is being made.

In operation the stamp is placed on the end of the thumb or the linger, as may be desired, and the operator grasps the article on which the imprint is to be made between the plate l0 and the opposing digit of the hand. The

pressure that accompanies this action causes the guard-plate to travel inward, swings the ink-pad from o the type, and allows the end of the type itselil to project slightly through the hole in the guard-plate and to make an imprint on the article grasped between the plate and the digit. Of course any suitable print ing character may be used.

That I claim is l. In a printing-stan1p, the combination of a ring adapted to encircle adigit ofthe hand, an impression-type secured thereto, an oscillatory ink-pad, a movable guard-plate and frame-pieces forming with the guard-plate a housing for the ink-pad, substantially as described.

2. In a printing-stamp, the combination of a ring adapted to encircle the digit of the hand, an impression-type secured thereto, framepieces secured to the ring, an oscillatory inkpad pivoted to the frame-pieces, a sliding guard forming a housing for the type and the ink-pad, and interconnections between the sliding guard and the type-pad, whereby they are actuated simultaneously, substantially as described.

In testimony whereot` I sign this specification in the presence of two witnesses.
