Patented Feb. 24, 1931 UNITED STAT-Es kPATENT orifice HARRY LiivY AND SAMUEL LoNscHEiN, or NEW YORK, N.l Y.; sain LEVY AssiGNon y To SAID LoNscHniN ik POCKET' IMPRESSION SEAL Application filed December 9, 1929. Serial No. 412,664.

This invention relates to newzand useful improvements.infseals.

Existing seals such as used by iiotaiies and othersfare operated by pivoted levers at right H angles to the planes oi the impression blocks thereof.v Necessarily the shape of the device is quite-bulky and awkward.V This prevents the'carrying of such a device in ones pocket .unless he is willing to stand for much inconl'venience.

It isfproposed to construct a pocket. seal Awith' an operating handle connected with a helixpressure stud, and moving in a plane parallel vwith .the plane of the Iimpression Thus when the device is ina folded position, the parts are flat andinay be conveniently carried in ones pocket without excessive bulk. In addition, the helix arrangement gives a great mechanical advantage even though' it occupies a very small space.

i More particularly,`the invention proposes a Ushaped body having arms Joined at one of their ends, animpression block .mounted 'on the inner side of one of the arms and engageable -by a complementary impression vblock movablymounted between the arms and urgeable into engagement by a helix pressure stud mounted .thruY the other of the arms and operable by a handle movablein ai plane parallel to the planes of the impression blocks. x

Forfurther comprehension of the invenrtion, and'of the .objects-and advant'agesthere-v of, reference will be had to'tlie following de- 'scription'and 'accompanying drawings, -and tothe appended claims in which the various novel. features of the invention'are more particularlyset forth. l

Fig. 7 is an enlarged longitudinal vertical sectional view taken on the line 7 7 of Fig. 1.

Fig. 8 is a perspective View of a handle similar to the one illustrated in Fig. 1 but of inodied form.

The device consists of a U shaped body having an arm 10 and a second arm 11 joined to each other at one of their ends. An impression block 12 is mounted upon the inner side of the arm 11 and is engageable by a complementary impression block 13 movably arranged between the arms and urgeable into engagement by a helix `pressure stud 14 mounted thru the other of the arms and operable by a handle 15. f

The said arms 10 and 11 at their joined ends are held together by a large screw 16, and have interengaging lips 17 and 18 for relieving some of the strain from the screw during use Yof the device. Furthermore, the lips prevent relative rotating of the two arms even though only clamped by one screw.

The said arm 11 is formed with a recess 19 in which the said impression block 12 rests. This recess necessarily is located on the inner side of the arm, and an aperture 20 in the arm communicates therewith sol that the impression block may bevlrnocked .out from the recess if this is desired. The pitch oi' the helix stud 14 is quite large so that upon movement of approximately it will have f advanced sufficiently to cause engagement et the impression blocks.

A. leaf spring. 21is disposed between the arms 10 and 11, and at one of its ends is engaged between the joined.. ends of the arms. A pair of screws 22 serve to fasten the leal spring uponr the'arni 11. Thesaid compleinentary impression block 13 is attachedupon the leaf spring 21 and this constitutes the movable mounting thereof.

A stoppin 23 projectsfrcmthe top iaccor :the arm 10 near one edge thereof and serves as a stop for the handle 15.A In the 'closed position of thehandle, it is only possible toA iiioveit to its open position sincerit is limited againstjrotation inthe wrong diree tion by the pin. A snap catch Q4 is arranged for holding the handle in its closed position and consists of a' ball 25 pressed outwards by a spring 26 mounted in the arm l0. Thel handle l5 is formed with a'smail recess into which the lball engages-aud accomplishes the latching. This maybe lseen from an inspection of Fig. y a

Preferably the device should be constructed pear-shaped in planviewI for'convenience `in handling and for small constructionfThe handle l5 is formed with an opening?? constituting a linger opening for themanipulation thereof. Attention is called to .in which the handle is shown in its closed position and the impression blocks-together. Fig. 7 the handle` is shown in itsopenposi- `tion* and :the impression bloclrs'separated.

Aln Fig.. 8a modified form of handle has been-.illustrated for the device. At .times when the sealis usedupon fairlyteugh paper, it may he necessary to increasefitheieverage and this isaccompl-shed `byf,theadjustable handle. The .handle indicated by reference numeral l5 consists of: two sectionsslidably connected 'preferably by.a.rdovetailed construction and,` limited ,against complete .dis-

i engagement by arpin Q8 projecting from one of the sections and engaging in a slot 29 in the other-section. .The slidable' connection should be :quite tight so lthat friction cani be depended upon to maintain the .handle in its contracted fposition. -For increasing the leverage it is only necessary .tn draw the sec; tionsapart. f Access may be had to the impression blocks for purposesof repairorreplacement by `re- .moving the screw. 1G. Then the arms ldand :llanay b e'separated. Upon a'. removing of the screws 22, the leaf spring 21 may-'bedisengaged and the* .nnpressionblocks are exposed.

`heunot in use, the handle is urged into "the position as shown in FigQQ, andthe catch is dependedupon .to maintainlthisposition. It
