LOUIS K. SCOTFORD, OF CHICAGO, ILLINOIS, ASSIGNOR T HILL-INDEPENDENT MANU- FACTURING COMPANY, 0F PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF ILLINOIS.

HAND-STAMP.

T0 @ZZ trimm it may concern:

Be it known that I, Louis K. Scorronn, a citizen of the United States of America, and a resident of Chicago, in the county of @ook and State of Illinois, have invented certain new and useful Improvements in Hand-Stamps, of which the following is :t specification.

This invention relates to improvements in that class of hand stamps shown in my Patent No. 668,021 of February 12, 1901.

The object of the invention is to provide a stamp of the character shown in said patent which will be capable of ready ad- `iustment and which will have other advantages hereinafter described.

lrThe invention` in its preferable embodiment, consists in the construction hereinafter more particularly described and illustrated and then definitely claimed.

In the drawings accompanying and forming part hereof: Figure 1 is a side elevation of a stamp made in accordance with my invention. Fig. 2 is a sectional view through the line 2 2 of Fig. l. Fig. 3 is a perspective view of the base plate and die plate, the die plate being thrown open. Fig. 4 is a perspective view of two details. Fig. .5 is a sectional detail.

Referring now to the details of the drawings by numerals t-1 designates the main frame of what is known as the tumbler form of stamp, and as usual comprises a handle 2 for depressing the yoke 3, the ends of the latter having a spindle 4 connecting them and passing through the side members 5 and 6 of the frame 1D this spindle being the center on which the printingcharacters S are tumbled when the handle 2 is depressed in order to move the printing characters from the inking to the printing position.

The main base plate is made similar to the base plate of my aforesaid Patent No. 668,021 and also on the same order as the base plate of my application Ser. No. 686,930, filed March 28, 1912, and has side arms 12 and 14 projecting therefrom, these arms being perforated as indicated at 15 through which the aforesaid spindle 4 passes. At the points where the spindle passes through the perforations 15 of the side arms 12 and 14, I insert a bushing 1S having a flange 20. These bushings surround the spindle 4 and the ianges 2O are lo- Specifcation of Letters Patent.

Serial No. 745,516.

cated between the side arms 12 and 14 of the movable base plate 10 and the side members 5 and 6 of the frame 1. The purpose of these flanged bushings is to prevent contact of the side arms 12 and 14 with the side members 5 and 6 of the frame 1 so that should any ink from the pad ooze down on the side arms 12 and 14, it cannot come in Contact with the side members 5 and G.

The main base plate 10 is provided with the usual flanges 22 and 24 and within these flanges is pivoted the supplemental die plate 26, the latter being hinged on the pivot 23. In order to lock this supplemental die plate 26 to the main plate 10 and to cause it to spring open when released I provide the following parts-the supplemental die plate 26 is provided with a grooved pointed pin 30 which7 when the die plate 26 is closed against the main base plate 10, passes through a perforation 32. On the under side of the main base plate, I provide a sliding catch 34 which has an opening 36 throughV which the pointed pin 30 enters when the supplemental plate 26 is closed against the main base plate 10. Co-acting with this sliding catch 34 is a spring 3S which is firmly secured to the under side of the main base plate by means of two rivets as shown in Fig. 2. A spring finger 42 is provided which may be integral with said spring 38 and which co-acts with a flange 44 on the slide 34 to cause the slide 34 to co-act with the groove in the pointed pin 30 and lock the supplemental die plate 26 to the main base plate 10. IVhen it is desired to release the die plate from the base plate the operator merely has to press upon the flange 46 of the slide 34, moving said slide 34 against the tension of t-he spring linger 42, when the slide will be moved so that the pointed pin 30 will be released from said slide 34, The supplemental die plate may now be opened upon its pivot 28.

In order to open the die plate automatically, I provide a spring 50 which passes through the opening 11 in the base plate 10 and contacts with the under side of the supplemental die plate 26. This spring, in the embodiment shown, projects from the aforesaid spring 38. Thus when the supplemental die plate 2G is closed against the mainbase plate 10, the former strikes against the spring 50 and shoves it downward until the supplemental die plate 26 is closed against the main base plate l0, at which time the spring finger 42 causes the sliding plate 34 to move within the groove of the pointed pin 30 and lock the supplemental die plate 26 to the main base plate 10. W'hen it is desiredl that the die plate 26 shall move away from the main base plate l for the purpose of changing the position of the type 8, all the operator has to do is to shove the projection 46 on the slide 34. This, as before explained, moves the slide 34 against the tension of the spring finger 42 so that the grooved pointed pin 30 is released from the slide 34, whereupon the spring 50 forces the die plate 26 outward on its pivots to the po- I sition shown in F ig. 3.

From the foregoing and accompanying drawings it will be seen that I have provided a stamp of such a construction that the supplemental die plate may be opened very easily for the purpose of adjusting the type and that I have also provided a stamp wherein the side arms of the movable die plate are held away from the side members of the main frame so that the inl: from one cannot be transferred to the other.

Vhat I claim as my invention is:

1. In a hand stamp, a main plate, a supplemental die plate hinged thereto, a sliding latch constructed and arranged to hold said t die plate to said main plate, a spring secured to said main plate and projecting through an opening therein against the die plate to force the same away from said base plate, and a spring co-acting with said sliding latch to hold the latch in its locking position.

2. In a hand stamp, a main plate, a supplemental die plate hinged thereto, a sliding latch secured to one of said plates and constructed and arranged to hold said plates together, a spring secured to said main plate and having a member projecting through an opening therein against the die plate to force the same away from said base plate, and a spring member co-acting with said sliding latch to hold the latch in its locking position.

3. In a hand stamp, a main frame having side members, a die plate supported in said frame between said side members and having parts projecting therefrom by which the die plate is turned, and bushings carried by said projecting parts having flanges located between said projecting parts and the side members of the frame and preventing i said parts from contacting.

In testimony whereof I aiiiX my signature i in presence of two witnesses.
