Application September 9, 1939, Serial No. 294,220
IZCIaims.
This invention relates to tablet packing and counting machina and particularly to such machines for attachment to Btandagd tablet forming machines of the type having rotary heads on 6 the surface of the peripheries of which the tablets are formed and carried during operation of the machine.
It has for its objects:
First, to produce a new and improved machine of the type described.
Second, to produce such a machine which is positive in its operation and which may be easily adjusted to take tablets in diflerent numbers from the same machine without complicated ad- Justments.
Third, to provide such a machine in which there are two troughs with wings to scrape the tablets from the surface of the revolving head, one of which wings is slidable across the head making the machine capable of satisfactory use on high speed tablet formihg machinery without crushing the tablets during shifting of the wing.
Other objects and advantages pertaining to de- 9 tails and economies of construction and opa'ation will appear from the description to follow. The invention is defined in the claims. A preferred embodiment of my invention is illustrated in the accom nying drawings, in which:
Fig. 1 is a perspective view showing my new and improved machine.

Fig. 8 is a top plan view of the operating mech-- anism.
Fig. 9 is a detail sectional view taken on the line !8 of Figs. 2 and 6.
My improved machine designated generally at I consists of a rotary head 2 which moves in a counterclockwise direction as viewed in Fig. 3. The tablets I are formed in the recesses 4 in a ll conventional manner and on completion are carried on the surface head. 0
A trough 5 is provided extending from the head to carry tablets therefrom. A wing i on the far side of the trough with reference to the move- 5 ment of the head extends across the surface of the head to scrape the tablets therefrom and guide them to the trough 5. This wing extends obliquely across the path of movement of the tablets and in a direction generally opposed to the movement.
A second trough l is provided to receive tablets. This trough has a wing I which is slidably mounted at the far side of the trough with reference to movement or the head. This slidable'wing 8 is mounted in a suitable slideway 9 and may be moved from a retracted position out of the line of movement of the tablets obliquely across the surface of the head as shown in Fig. 3 to intercept tablets and guide them to the trough 1, the movement being in a direction generally opposed to the line of movement of the tablets so that the tablets will be scraped from thehead and will be guided to the trough when the wing is in the position shown in Fig. 3. This movement permits the wing to knife its way into .position and to be retracted from tablet intercepting position without crushing the tablets as might be the case ii the wing were a pivoted wing.
The wing is operatively connected by bell crank lever I I and pitman II to the operating mechanism indicated generally at II, which is provided with a suitable supporting frame l3 in which a rockshaft I4 is pivoted. The rockshaft is provided with a crank l5 and a cam follower Ii which is engaged and depressed by cam I! carried by the head 2 on each revolution of the head.
A return spring it rocks the shaft back to place the cam follower in position for further actuation by the cam after the cam has passed on the revolution of the head.
0n the rockshaft I4 is a crank or lever I! to which is connected a lever 2) which carries a pawl 2| which is reciprocated from the full line position shown in Fig. 2 to the dotted line position there shown on every reciprocation of the rockshai't. A ratchet wheel 22 is disposed for rotation about the axis of the rockshaft on a shaft 23 which extends coaxially of the rockshaft. A cam wheel 24 having a plurality of lobes 25 is con- 60 nected to said ratchet wheel to be rotated upon rotation of the ratchet wheel.
Reciprocation of the pitman II is ;brought about by means of a yoke 2 which is voted at 21 to the pitman. A pair of levers or plates of the periphery of the provided with notches 34 and 35 whichfare op- I posed to dhe another and are adapted to receive ,a pin 36 on a lever 31 which is pivoted at 38 to a plunger '39 which is mounted for vertical sliding movement. The plunger 33 is provided with a pin 40 which is engaged by the cam lobes 25 on the cam wheel 24 on rotation thereof in a counterclockwise direction as viewed in Fig. 2,
to provide for a downward movement of the plunger. I
The downward movement of the plunger shifts the pitman as follows: At the upptfi portion of the stroke, the pin 36 will be engaged in either notch 34 or 35. If it is engaged in notch 34, as shown in Fig. 4, the lever or plate 28 will be pivoted in a counterclockwise direction until it assumes the dotted line position, thus shifting the pitman. Upon shifting of the pitman, the pin 4| to which the spring 42, which is likewise attached to pin 36, is fastened, shifts to the dotted line position shown in Fig. 4, causing the pin 35 by toggle action to snap over into the notch 35 so that upon the next reciprocation of the plunger 39 the pitman will be shifted back to the full line position shown in Fig. 4.
The pawl 2! is held out of engagement with the ratchet 22 by means of a plunger 43 carrying a pin 44. The plunger 43 is spring pressed upwardly by spring 45 and has at its end a cam follower portion 46.
' A ratchet wheel 41 is mounted on the frame i3 and is provided with an actuating pawl 48 which is operatively connected by a pitman 49 to the crank IS on the rockshaft I4. This pawl is arranged to rotate the ratchet wheel 4'! once for every revolution of the head. Attached to the ratchet wheel 41 is a cam wheel 50 which has at its periphery a plurality of tapped holes 5| to removably receive the screw threaded cam members 52 which may be inserted in the holes so that after a given number of rotations of the head the plunger 43 will be depressed to permit the pawl 2| to rotate ratchet 22 and cam wheel 25 to actuate the slidable wing.
It will be apparent that with the mechanism above described, the slidable wing 8 will be either retracted or advanced at the end of a given number of revolutions of the head which always produces a constant number of tablets. Bythis means it is possible after a given number of tablets have been formed and passed through one trough to cause the tablets formed on the head to then go to the other trough so that as one bottle is filled and removed, another one can be receiving tablets from the machine.
The cam wheel 50 is so arranged that it is a simple matter to change the number of revolutionsnecessary to effect a shift in the position of the wing and it is not necessary to tear down the mechanism to make this change since the spacing and number of cams 52 control the operation of the mechanism which shifts the wing 8. It will be apparent that the mechanism for shifting the pitman is a highly satisfactory and positively operating mechanism which permits the shifting of the pitman back and forth by 9.
similar movement of the shifting mechanism and that the shifting mechanism will operate speedily so that the shifting movement of the wing will be effected without delay.
The terms and expressions which have been a herein employed are used as terms of description and not of limitation, and there is no intention,
in the use of such terms and expressions, of excluding any equivalents of the features shown and described, or portions thereof, but it is recognized that various modifications are possible within, the scope of the invention claimed.
