Filed Nov. 25, 1938 Patented Jan. 23, 1940 2,187,773'xiv SEAL PRESS Frank, H. Eyman, Oak Park, Ill., assigner to Art Novelty Manufacturing Company, Chicago, Ill., a corporation of Illinois 'Application November 25,1938, Serial No. 242,264 n 1 Claim. (Crm1-.3)

This invention relates to seal presses and has for its object the provision of an improved arrangement of parts by reason of which the seal elements can be quickly and easily removed from the press and others substituted therefor. Improved means is provided also for locking the press in closed condition so as to make it compact and convenient to carry, the arrangement preferably being such that the spring-connected seal members when removed from operative position can be pressed together and fitted between the handle and the operating lever of the press so as to be held releasably in position by the pressure of the connecting spring.

t is a further object of this invention to improve presses of this type in sundry details hereinafter pointed out, the preferred means by which the several objects have been accomplished being illustrated in the drawing, in which Fig. l is a face view of the preferred form of the press;

' Fig. 2 isa view of the press as seen from the left in Fig. 1, but with the operating lever in its closed position;

Fig. 3 is a top plan View of the press as seen in Fig. 2;

Fig. 4 isa vertical cross sectional View taken at the line ll--l of Fig. 3; i y

Fig. 5 is a face view of a fragmentary portion of thepress corresponding to a portion of Fig. l but with the operating lever in changed position;

the line 6--5 of Fig. 4;

Fig. 'l is a perspective View of the yieldingly connected seal members removed from the press; and

Fig. 8 is a View similar to Fig. 4 but showing the seal members removed from operative position and held by friction in changed position for convenient storage of the press.

Referring now to the several `figures of the drawing, in which corresponding parts are vindicated by the same reference characters, I5 indi cates a frame member in the form of a channel, comprising arms I6 and I'I connected by an intermediate web portion I8. As is clearly shown in Fig. l, each of the arms of the channel member I5 is provided with a deep notch I9 in one side portion so as to receive connected seal members 2b and 2i thereinto.

In the arrangement shown, the seal member 2l is provided with a stiff arm 22 rigidly connected therewith and extending laterally therefrom. The seal member 20,in the construction lillus- Fig. 6` is a vertical cross sectional View taken at y trated, is provided with a comparatively very yielding resilient arm 23 iixedly connected with the seal member at one end and likewise extending laterally therefrom. ".As is'best shown in Fig.

7, the arms 22 and 23 are strongly connected to- 5 75' together the spring arm 23 and the cooperating l0* connecting means cause the seal members to move into cooperative relation to each other.

As is best shown in Fig. A8, rthe seal member 2I is provided with two openings 24 therein which are adapted to be brought into engagement with 15 lugs 25 carried by the frame arms II and Il for holding the connected seal members releasably in fixed position in the framework, withy the seal members extending into the notches I9 of the frame arms. Connecting arms 22 and 23 can be inserted readily between the frame arms I6 and Il from the left in Fig. l, the seal membersl 20 and 2l being pressed together to the necessary extent for enabling them to ybe inserted in the notches Iii. opening 2li in the seal member 2l are then brought into operative engagement with the lugs 25,

whereupon the seal members are permitted to separate slightly under the influence of the springA arm 23. bers are maintained inposition, with the seal member 2| held stationary andthe seal member 2D movable toward and from the seal'member 2I, such movement of the seal member 2U being effected without any tendency for the connected 35 seal members to be detached from the frame.

For effecting a movement of the movable seal member 20 toward and from the stationary seal member 2|, I have provided an operating lever 26 formed of sheet metal bent into a channel for- 40 mation, such lever being pivotally mounted in position upon the arms I6 and yIl by means of a pivot pin 2l extending across the frame member I5 transversely thereof. Upon the lever 26 in eccentric position with respect to the pivot pin 45 2l, I have mounted a segmental roller 28 by means of a pivot pin 29, such roller 28 being cut away at its upper side portion so as to have clearance with respect to the pivot pin 2l of the operating lever 26. The arrangement is such that upon a stroke of the operating handle 26 in clockwisedirection in Fig. 1 the roller 28 is pressed downwardly on l the seal member 2|] for moving it into cooperative relation with the seal member 2 I, as is best shown in Fig. 4. The downward movement of the roller The arrangement is such that the 20'"- The 25 Under these conditions the seal mem- 30;-,

' 28 applies substantially a toggle pressure eiect upon the movable seal member 2G for pressing it downwardly with a minimum of effort on the part of the operator.

Means is provided in connection with the operating lever 2S for holding the lever in its closed position. This means comprises a plate 3D oilset slightly at an intermediate point so as to permit the platey to be slidably mounted to advantage upon the web of the channel-formed lever 26, with the plate extending through an opening 3l in said web portion as is best shown in Figs. 4 and 8. At its outer end, at the left in Fig. 1, the plate 30 is provided with a downwardly turned end portion 32 which is cut away partially to provide a transversely extending lug 33. This lug 33 is in such position with respect to the lever 26 that when the lever is in its lowered position as shown in Fig. 5 said lug 33 stands directly opposite the space between a lug 34 on the handle and a shoulder 35 on the frame arm I6. With the parts in the position as shown in Fig. 5, the plate 30 may be given a slidable movement toward the right in Fig. 5 to the position as shown in Fig. 4 in which the lug 33, by engagement with the lug 34 and the shoulder 35, serves to lock the handle 2S in its lowered position.

Upon the pivot pin 21'! (see Fig. 4), I have mounted a coiled spring 36 having one end portion in engagement with the lower face of the plate 3i] and its other end portion in engagement with the segmental roller 23. The spring is so arranged as to press downwardly upon the roller and upwardly upon the plate, serving normally to hold the roller 28 in operative position for engagement with the seal member 20 and to press the plate 36 into frictional engagement with the handle 26 for causing the plate to remain in any adjusted position to which it may be moved.

In the arrangement shown, the frame member l5 is extended toward the right in Fig. 1 some little distance beyond the ends of the notch l5) so as to provide a handle 3l positioned directly opposite the handle portion of the operating lever 26.

It is believed to be unnecessary to describe in detail the operation ofy my improved device.

When the device is to be used, the lever 26 and the handle 31 are pressed together so as to bring the seal members 26 and 2l into cooperative relation to each other. If it is desired to use the press with a plurality of sets of spring-connected seal members, the removal of one set of seal members and the substitution of another set can be very quickly and easily effected. When the press and seals are to be packed for storage or for transportation, a set of the connected seal members can be inserted between the arms of the channel frame member as shown in Fig. 8, the spring 23 serving to hold the seal members in frictional engagement with the frame arms I6 and Il so as to hold the seal unit releasably in position.

While I prefer to employ the form and arrangement of parts as shown in my drawing and as above described, it is to be understood that my invention is not restricted to the form shown except so far as the claim may be so limited, since changes might well be made in the form and arrangement of parts without departing from the spirit of my invention.

I claim:

In a-seal press, the combination of a frame member having a deep notch open at one side of the frame, two seal members, means movably connecting said seal members together and normally holding them yieldingly in slightly spaced relation to each other, means for holding said connected seal members releasably in said notch of the frame member, a lever pivotally mounted on a transversely extending pivot pin between two transversely spaced portions of the frame, a roller journaled on said lever in position to apply a toggle pressure effect on one of said seal members for forcing it into operative engagement with the other seal member upon an operag tive stroke of the lever, said roller being mounted in slightly eccentric position with respect to the pivot pin of the lever and being cut away at one side portion so as to clear said pivot pin, a locking plate slidably mounted on said lever, a shoulder on said frame member adapted by engagement with said locking plate to hold said lever releasably in position for maintaining said seal members in operative engagement with each other, and a spring bearing on said roller and on said locking plate serving to hold the roller normally in position for operative engagement with one of said seal members and to press said locking plate into frictional engagement with the lever for holding the locking plate normally in any adjusted position to which it is moved.
