Specification of Letters Patent.
Patented Nov. 23, 1909.
Application filed May 27, 1909. Serial No. 498,692.
To all whom it may concern:
Be it known that I, CHARLES HERBERT HAMMOND, a citizen of the United States, residing at Baltimore, Maryland, have in vented certain Improvements in Tobacco- Presses, of which the following is a specification.
This invention relates to certain improvements in Letters Patent No. 489,741, granted on the 10th day of January, 1893 to Thomas Hill for a tobacco press; and the object of the present invention is to provide a press of substantially the same character as the one shown and described in the said patent, with means whereby the plugs of tobacco after the completion of the compressing operation, and upon the elevation of the vertically reciprocating com ressing plunger, are automatically ejected from the mold, as will hereinafter fully appear.
In the further description of the said invention which follows, reference is made to the accompanying drawings, forming a part hereof, and in which,-
Figure 1 is an exterior side view of such parts of the machine as are involved in the present invention. Fig. 2 is' an exterior front view of certain parts of the same. Fig. 3 is a view similar to Fig. 2 except that certain parts thereof, are shown in section. Fig. 4 is a perspective view on a slightly enlarged scale, of the principal parts of the machine which constitute the present invention,- together with certain elements of the patented machine which are connected therewith. Fig. 5 is a partly sectional view of certain parts of the mold-closing mechanism hereinafter described.
Referring now to the drawings, 1 is the frame of the machine, and 2 the driving shaft carrying the mutilated spur pinion 3, which transmits an intermittent rotary movement of the spur gear wheel 4 on the shaft 5.
7 is a stand erected on the frame 1, to support and guide the vertically sliding head 9 which receives its motion from the crank 10 on the shaft 5, through the medium of the link 12 the upper end of which (not shown) is pivoted to the said head.
13 is the mold wherein the plugs of tobacco are compressed, the rear plate a of which is stationary, and the side plates 2) and 0 shown as fixed.
15 is a plunger arranged to have an upand-down movement in the mold 13. Its head is united by an adjusting screw 17 to the upper end of the sliding head 9.
The front wall or plate 16 of the mold, shown only in Figs. 2 and 5 of the drawings, as in the patented machine, has a forward and backward, as well as a tilting motion between the side plates Z) and c, and it is the former motion alone that has any bearing on the present invention. It is effected primarily from a crank disk not shown, through the medium of the rod 18, the arms 19 and 20 on the oscillating shaft 21, the link 22 and the plate 23 (see Figs. 1 and 5) which slides on the surface of the table 24.
All the parts of the machine so far mentioned, and the means for effecting their movement, in cases where movements are required, are substantially shown and described in the said patent, and any further description of them is therefore unnecessary.
Referring particularly to Figs. 3 and 4 of the drawings, it will be seen that within the side plate 0 of the mold, is a plug'-eject ing plunger 25 the inner face of which is normally flush with that of the said side plate; and that at thebottom, the side plate 0 is provided with an opening 27 for the exit of the plug. lVithin this opening is placed a forward and backward moving door 28 hereinafter more particularly re- -f'erred to.
The plug ejecting plunger 25 has a bar (Z extending laterally therefrom, which is linked to the lower end of a lever 29 pivoted at c to some stationary part of the frame 1.
The upper end of the lever 29 is connected by a link 30 to the upper end of a second lever 31 fulcrumed at g to the frame 1. The lower end of the second lever 31 is held yieldingly in contact with the face of the spur wheel 4 by means of a spring 32 which isattached to a fixed stand 33; and its movement whereby the plunger 25 is forced into the mold 13 to push the compressed plug through the opening 27 in the side plate 0, at the time that the plug-compressing plunger 15 is raised for the placing of a crude plug into the mold, is effected by an inclined cam-block 35 on the face of the spur wheel 4.
The sliding door 28 which is adapted to close and disclose the opening 27 in the side plate a of the mold, is provided with a bar 37 which extends a considerable distance beyond the mold, where it is suitably guided as shown in Fig. 1. At its end the said bar is fitted with a hinged latch 39 having a catch or tooth h on its underside; and the latch is connected to some stationary part of the machine by means of a coiled spring 40 which serves in circumstances hereinafter described, to draw the door back and so close the opening 27 in the side plate 0 of the mold. The spring also serves to retain the latch yieldingly in its lowest position for a purpose hereinafter described.
41 is a block shown in section in Fig. 5, in full lines in Fig. 1, and in dotted lines in Fig. 4, formed as a part of the sliding plate 23, adapted in its extreme inward or forward position wherein the mold is closed, to engage with the latch as shown in Fig. 5. By such engagement, the sliding door 28 becomes connected to the said sliding plate, and in the backward motion of the latter the opening 27 in the side plate 0 is disclosed for the exit of the compressed plug which is forced therethrough by the action of the plug ejecting plunger 25.
As, it is necessary that the opening 27 should be closed before the beginning of the compressing operation, I detach the latch 39 from the block 41 as the sliding plate 23 approaches its extreme backward position; and to attain this end, I employ thefollowing mechanism: To the frame 1 I pivot a lever 42 the inner end of which is spring held, and provide the crank 10 with a pin 44 which serves to trip the beveled end of the said lever'at the time that the tooth h of the latch 39 is to be lifted from contact with the block 41.
46 is a tripper susceptible of an up-and down movement at the front edge of the table 24, and over which when the same is in its lowest position, the latch 39 passes without being raised; and the raising of the tripper to release the latch from the block 41 and allow the sliding door 28 to suddenly close, is derived from the mechanism which will now be described. The tripper is pivoted to the outer end of the cross arm 49 pivoted at z to a stationary lug 50 on the underside of the table 24, and its inner end is connected by means of a link 52 to the end of the lever 42. By means of the devices described, the sliding door is carried outward or backward by the block 41 as the front plate 16 of the mold is opened, and at the proper time suddenly closed before 55 the plate 16 closes the mold.
The movements of the unions parts of the machine as described are so timed that when the compressing plunger 15 is about to descend, the mold into which a crude or 0 unfinished plug has been placed, is in a closed condition, and after the compression of the plug is accomplished, and the plunger has begun its ascent, the exit opening 27 in the side plate 0 of the mold is disclosed by 5 the withdrawal of the sliding door 28, through the medium of the latch 39 and the block 41 on the backwardly sliding plate 23. As soon as the opening 27 is fully disclosed the plug ejecting plunger 25 passes into the mold and forces the compressed plug through the said opening, and then moves back to its original position. The mold is now ready to receive another crude plug, but before this is inserted in the mold, the tripper 46 comes into action and by releasing the latch 39 from the block 41, the sliding door is again closed, and the operation of the machine as described is repeated.
1 claim as my invention,-
In a tobacco press, the mold thereof having a movable front wall or plate with means to effect its alternate motion toward and from the mold to close and open the same, and the mold having also an exit opening in one of its side plates, and a reciprocating plunger adapted to pass through the other side plate and into the mold, combined with a sliding door for the said lateral opening, means to produce a reciprocating movement of the said plunger, and independent actuating devices to effect the opening and closing of the sliding door, the said motion-producing appliances being arranged in such manner as to effect the closing of the lateral opening in advance of the forward or closing operation of the front plate, substantially as specified.
