Application September 6, 1933, Serial No. 688,348 7 Claims. (01. s-1)' This invention relates to a machine for clamping frames on pocketbooks.

The object of the invention resides in the provision of a machine by means of which frames 5 may automatically be clamped on the edges of pocketbook bodies. 7

In the drawings:

Fig. 1 is a side elevation, partly in section, of a machine constructed in accordance with my 10 invention;

Fig. 2 is a horizontal sectional view of line 2-2 of Fig. 3;

Fig. 3 is a vertical sectional View of a portion of the machine;

Fig. 4 is a vertical sectional View on line 44 of Fig. 2; and

Fig. 5 is a perspective view illustrating the type of pocketbook on which the machine is adapted to operate.

frame 1 is attached to the body portion 2. This frame 1 is U-shaped in cross section as shown in Fig. 3 and the sides are pivoted together as at 3. The upper edge 4 (see Fig. 3) of the .pocket- 5 book body 2 is clampedbetween the flanges of the frame 1.

The machine of this application is adapted to tuck the upper edges of the body f the pocketbook between the flanges of the frame 1 and to clamp the flanges onto saidso tucked edges of the body of the pocketbook.

The machine consists of a frame 5 which supports a seat 6 for the pocketbook body 2. This seat 6 is provided with a recess 7 of substantially the same shape as the body of the pocketbook 45 face plate 8.

when the latter is open. This seat carries a face plate 8 on one side of which is mounted a fixed abutment 9 andon the other side of which is mounted a movable abutment 10. A retaining plate llhaving a bevelled edge 12 is adapted to urged inwardly by a spring 17 to cause the bevelled edge to overlie the adjacent flange of the pocketbook frame. This spring 17 operates between a protrusion 18 on the retaining plate 14 and a protrusion 19 on the abutment 10. A cam 55. 20, pivoted at 21 in permanent relation to the In pocketbooks of the type shown in Fig. 5 a

seat 6 by means of a bracket 22, operates against the protrusion 19 and is controllable by handle 23. A link 24 pivotally secured at 25 to the re taining plate 14 is pivotally' and slidably secured to the cam 20 by a set screw 26.

A plunger 27 of the general shape of the pocketbook body 2 and on which the body is adapted to be secured by means of pins 28 is mounted on a rod 29 which is slidably mounted within an inner shaft 39. This shaft is removably attached at 31 to the main shaft 32 that is operated by toggles 33, which toggles are actuated by means of a treadle 34 through a connecting link 35 and a bell crank lever 36.

The plunger 27 carries a plate 37 on its upper face beneath which plate are slidably mounted a plurality of tucker blades 38. These blades 38 are connected to the inner shaft 30'by means of links 39 which extend through slides 40 in the plate 37.

I A punch 41 ismounted rigidly on themain shaft32. This punch carries, within itself, pivoted latches 42 that are normally'held in engagement by means of springs 43 with stationary latch elements 44.-carried by the plate 37. The en' gagement of these latches 42' with the stationary latch elements 44 maintains the punch 41' and the plunger 27 stationary with each other.. Each.

of these latches 42 has an arm 45 extending therefrom which arm protrudes through the punch 41' and supports the inner end of a lever 45 (see Fig. 1) which lever is pivoted at 46 to the punch 41. At the opposite end of the lever is an extension 47 and slightly inwardly from the extension a downwardly protruding projection 48. The upward movement of the inner end of this lever is limited by a'stop 49 carried by the punch.

Below each of these levers 45. is a trip 50 which.

is pivoted at 51 and the upper end of which is urged into the path of movement of the extension 47 of the lever 45' by a spring 52.

The plunger 27 is normally urged away from the punch .41 by springs 53 toward the position shown indot anddash lines in Fig. 4, which springs come into operation when the latches 42 are disengaged from the latch elements 44.

In operation the cam 20 is first operated by means of the handle 23 to withdraw the abutment 10 and the retaining plate 14 from the position shown in Fig. 3. The pocketbook frame 1 is then put in place as shown in Fig. 3 and the cam returned to its original, position whereupon the abutment 10 and the retaining plate 14 assume the position shown in Fig. 3 and holdthe frame in place on the face plate 8.

Assuming the parts in the positions shown in Fig. 3, which positions they occupy before the sequence of operations is started, the pocketbook body 2 is placed upon the plunger 27 in the position shown in Fig. 3, being held on the plunger by the pins 28. As the treadle 34 is actuated the shaft 32 is moved downwardly. The initial movement of the shaft is rapid due to the small angle of the toggles 33 but the rapidity decreases as the shaft moves downwardly and as the angle of the toggles 33 increases. Thus the plunger 2'7 is initially moved rapidly toward the seat 6 but as it approaches the seat 6 it is more slowly moved. When the projection 47 of each of the levers 45 engages the upper end of the trip 50 the lever is moved about its pivot 46 and moves the outer end 45 of the adjacentl'at'ches 42' downwardly to disengage the latches from the latch elements 44 against the tension of the spring 43; Immediately upon the disengagement of the latches 42 from the latch elements 44the springs 53 move the plunger 27 downwardly independents ly of and away from the punch 41 into position shown in dot and dash lines in Fig. 4. g

During this movement the downward projection 48 of each of the levers 45 engages the adjacent trip 50 and moves it into the dot and dash line position shown in Fig. 1 so that the lever 45 may return toits-initial position under the influence of the spring 43. i

As the downward movement of the shaft 32 continues the plunger 27 seats the pocketbook body within the recess 7 so that the upper edges 4 of the pocketbook body project slightly. above the frame 1-. After the plunger and pocketbook body reach these positions the downward movement 'of the plunger ceases and the compression of the springs 53 begins. However, the downward movement of the punchcontinues under the influence of the treadle. When the punch 41 arrives at a position just above the frame 1 the links 39 assume a horizontal or dead center position. As the links 39 approach the horizontalor dead center position from the dot and dash position shown in Fig. 4 the tucker blades 38 are moved outwardl'yand engage the inner faces of the pocketbook body adjacent the upper, edge. As the links 39 continue to approach the horizontal or dead center position the blades face the edges of the pocketbook body between the flanges of the frame 1 and when the links assume the horizontal or dead center position they have completed the tucking action.

- The a continued downward movement of the punch 41 moves the links 39 from their horizontal or dead center position toward and into the position shown in full lines in Fig. 4, thus withdrawing the blades from between the flanges of the frame 1. At the time the withdrawal of the blades is completed the punch 41 has engaged the bevelled faces 16 of the retaining plates 11 and 14 and moved them outwardly against the tension of the springs 13 and 17 and has reached such a position that it engages the upper flange of the frame 1. The continued downward movement of the punch 41 depresses the upper flange and clamps the edges of the pocketbook body between the upper and lower flanges. During this clamping action the latches 42 and the latching elements 44 again engage and under the influence of the main shaft 32 the punch 41 and the plunger 27 move upwardly as a unit into position fora repetition of the cycle of operations. a

While I have illustrated and described a particular embodiment of my invention it is to be understood that I do not wish to be limited to that embodiment but that I may make various changes in the details of construction without departing from the spirit of the invention or from the scope of the claims.
