HAND PRESS. APPLICATION FILED NHL 8. 1913(- Patented Apr. 1 1916;v


,iNVENTOR W/L L'IAM D. TFJOUP a citizen of the United States of America,



Specification of Letters Patent.

Patented Apr. is, me.

Application filed NovemberS, 1913. Serial No. 799,986.

To all whom it may concern:

Be it known that I, WILLIAM D. TRoUr,

residing at Frankfort, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Hand-Presses, of which the following is a specification, reference being had therein to the aocompanyingdrawing.

My invention relates to an improved hand stamp, and I declare that the following is a. full, clear, concise and'exact description thereof, suflicient to enable one skilled in the art to' make and use the same, reference being had to the-accompanying drawings in Which like reference characters refer to like parts throughout.

The device is designed for use in stamping the date of' receipt or delivery of papers,

of payment of bills, of the receipt of postal matter and also, if desired, the cancellation of the postage stamp.

In this improved style of stamp I have combined mechanisms which are simple and compact and which include a spring by which the printing portion or die, which is normally concealed, is projected by the blow of the operator into contact with the paper to be stamped, a spring which takes up the blow of the operator on the stamp, means which keeps the type-carrier from being displaced circumferentially, means for adjusting the degree to which the platen or type will be thrust out of the casing bythe operators stroke, and other particulars which will be more fully understood from the following description in connection with the drawings.

In the drawings Figure 1 is a full view of the device from the side; Fig. 2 is a vertical sectional view; Fig. 3 is a vertical sectional view of a portion of the printing part of the stamp; Fig. 4 is a vertical sectional view of a portion showing the operation of the printing portion by manipulation of the handle, showing the position of the parts when the impression is made; Fig. 5 is a view of the stamp from the bottom; Fig. 6 is a like view of a difi'erent style of stamp; Fig. 7 is a vertical sectional view of a modified form of construction of the stamp, while Fig. 8 is a like view of a further modification.

Referring to the figures more in detail, 1 is the handle, 2 is the casing and 3 is the spring, one end of which is-secured in the handle portion by having its bentend passed through the opening 4 and the other end of which is secured to a cap 5 by having its bent end passed through hole 6, so that when. the'handle and the cap and the casing 2 are tightly secured the movement of the handle is in a fixed vertical line relative to the stamp. Or, in other words, the handle is always in the same relative .position to the casing except for the longitudinal movement of the. handle relative to the case. The part 7,whie'h has been included" so far in mention of the handle 1, consists ,of a cap to'be threaded for its mounting-in the'handle, which bushing is centrallyapertured for the threaded stem 12 on which are mounted lock-nuts 13 and 13. This rod or stem 12 extends downwardly and is connected with the type-carrier 24, and the nuts 13 and 13 are for the purpose of securing the associated parts in place and adjusting the action of the type when coming into contact with the face to be marked. Collar 5 is screw-mounted to the casing 2 and is centrally apertured for the passage of the threaded stem 12 so as to allow free play of the stem in the aperture. At the end of the stem nearest to the typecarrier 24 is'secured head 15 which is hollowed out to receive the head 16 of the knob head 15 and make sure of a clear print by the type. The contacting surfaces of head 15 and knob 17 are curved, as seen, for free action. A wire 20 is passed through the knob 17 in loose engagement therewith, one end of the wire 20 being inserted in a bore in the collar 5 and the other end being inserted in the plate 22 which is secured to the type-carrier 24 on which oi ctain of the type are mounted. This prevents the type from turning circumferentially relative to the casing 2 and therefore relative to the handle. .This type-carrier 24 is mounted to move inward or outward in the casing 2, so that when the type is not employed the type-carrier is withdrawn Within the case -bv force of the spring 3 so as not to make which is adjustably screw-mounted on the stem 12 but which, when the stamp is not in use, as is seen in Fig. 2, is removed from the base of the collar 5. A lock-nut 30 is pro- 5 violed to fix the position of nut 29. This nut is so adjusted upon the stem 12 that the nut comes into contact with the oppositely disposed upper surface of collar 5 when downward movement of the handle 1 has caused 1 the type-carrier as to be projected from the casing 2 to the proper printing position. Thereafter further downward movement of the handle and consequent compression of the spring 27 does notexert further pres- 15 sure upon the type-carrier, but such pres sure is transferred through the collar 5 to the casing 2. In this way excessive pressure of the type upon the surface to be printed is avoided and thereby a blurred impression from the type is prevented. Furthermore, the downward movement of the handle 1 after the type-carrier has moved to printing position relieves the hand of the operator from the shock that would be received, were the handle positively stopped as soon as the typecarrier came to printing position. Such further downward position of the handle 1 after the type-carrier has come to printing position is allowed by reason of the fact that the upper end of stem 12 with its lock nuts 13 and 1?) simply passes upward into the cavity of the handle as the handle passes down against the resistance of the springs 27 and 3.

5 Referring to Fig. 8, 24 shows a type-carrier which carries the type, indicated by 3d, and which are mounted or arranged in a circle. The type-carrier, however, has a central aperture which is occupied by a clip 36 whichhas its outer edges slightly flexed inwardly as at 38, so that the rubber 40, on which the removable type 34 are mounted, or the sections of rubber, are held by reason of the inward flex 38 bearing against the rubber 40. The clip 36 has outward eX- tending portions 39 which overlie the surface of the type-carrier 24 and which have aperture 41 through which a proper tool may be inserted to withdraw the clip and the type 34 in the clip so that the type may be conveniently changed.

Referring in a general way to the entire construction, pressure on the handle 1 compresses spring 3 which sets the case 2 closely .55 against the paper on which the printing is to be made. The handle and the casing are in constant relation circumferentially. The pressure of the handle also compresses spring 27 which presses downward on the dishednut-and forces the typecarrier 24, with its type, downward into printing contact with the paper. The type-carrier and the fixed nut 5, (in effect the handle) are also in constant relation circumferentially. Though the handle may be given an oblique blow, the

casing 2 will strike flatly 011 the paper and the threaded-stem 12 being free to play at one end in the socket or cup formed in the collar 7, is at the other end free to give an oblique blow to the type-carrier 2st which, however, moves in right line in and out of the casing 2. It is to be noted that the heads 15 and 17 have curved contacting surfaces, as indicated more fully in Fig. 1, so that the tilting of the handle, while perlnitted by the flex of the two springs, does not interfere with the printing stroke which is along the axis of case 2, as the stem 12 may tip freely to the one side or the other.

In Figs. 1 and 5 is shown a lateral projection-l2, the face of which is suitably designed, as seen in Fig. 5, to effect the cancellation of a postage stamp, at the same time that the date of mailing is marked by the stamp proper. v

In Fig. 2 it is seen that the case 2 may have an outward rim, in substance a thickening of the edge, to preventcutting of the 'paper or damage of the contents of an envelop by a sharp blow of the stamp.

It is also noted that the construction relative to the changeable portions'of the stamp or type provide for the use of desired words and figures, as for months and days.

In Fig. 6 at oneend of the stamp is shown a space w in which may be inserted a die with any suitable mark thereon, as for instance, a mark indicating a train number or route designation, the stamp being interchangeable, as indicated in Fig. 5, as may be desired. A further interchangeable stamp may be provided in place of the star, if

' desired.

In Fig. 7 I provide the'handle 1 and the casing 2 with the type-carrier 24 mounted therein. I also provide the small spring 27 which, however, plays in tube 27*, having an outward'rim 27 near its base which when the stamp makes an impression lodges against the inwardly projecting rim 27 of the case 2. The tube 27*- is slotted at its upper end as indicated at 30*, for the insertion of the pin 30 which passes through plug 30 against which the spring 27 bears. The handle is secured from excessive move- 5 ment relative to the casing 2 by reason of the fact that a cap 31 is secured on the end of tube 27 Then the handle is pressed the sp ing 27 is first compressed which places the type in contact with the 12;)

surface to .be printed,- a further pressure on the handle compressing the spring 3 which takes up the blow and also acts to effect the printing by the letters.

In Fig. 8 the stem 12 has nuts 13 and 125 13 butbctween them is secured a member with projections 14* and 14 which pass through cap 7 by which the cap 7 and the screw 12 are held relative to each other. At
