to the left, as shown in Figs. 1 and 7. In this position, the projection 25 bridges the space between the cam crests 26 and 2'! so that the de- *'pression 28 is ineffective in permitting the rod 30 to move to the right. However, as the gear 9 and circular cam Ill turn through 180, the cam depression 29 permits the rod 30 to move to the right, as will be'p'erfectly 'ObV'idll'S. It will of course be understood that the projection- 25 may take the form'of a semicircular ring projecting from the face of the plungerlfi, the projection being of sufficient width to'serve as a track for the roller Power is supplied through a belt 3| to a belt pulley 32 on the shaft 33 and from"- the pulley 32 through shaft 33 to gear '8. From this, power is transmitted to gears 6 and 1 and the remainder of the gear train driving the distributing screws. As shown inFigs. 1, 2, and 4, a gear, la, on the shaft of screw 5, is directly in front of the gear '1 and hides the same from view.

This'gear 7d meshes with the gear '9 and has the 'same 'numbe'r of teeth as the gears '6' and I. The gear 9 has, preferably, twice the number of teeth of the gear's'fe, I, and'ia. A gear 8;; connects the gears l and} in driving relation and, together,

the ge'a'r'sii, 'l, la.,f8, '80, and '9 constitute a gear train, the gears of which are constantly in mesh,

whether they are in the position illustrated in "Fig. 4, that illustrated 'inFig. 5, or in any intermediate position.

described presently.

-At';the left 'side' of the machine a pair of arms 34 andtfi, constituting a compound lever, are

The purpose of this will be jniounted upon a pivot member 36 and are capable of having their relative positions adjusted by means of ithe screw "31' These two arms 34 and s5 are connected by means of a spring 38 which normally holds them in a fixed position with meet 'to each other. A spring 39,. connected to :thedistributo'r boxl'll and to the 'arm 34, normally pulls this latter as far to the right as the rod?!) 'permit itto go. A finger '4 l, pivoted at. A2 jupon the a'rm 3'5 '('s'ee Fig. 9) ,"is pressed bya springfiS against a stop' i't mounted between 'two arms qe pr'ojec'ting from'a corner of the distributing bog: it. An abutment member it has a socket formed therein for the reception of one end of the spring 43, and. the spring therefore presses icdnstantly against the linger '41 to hold it against thes top member l l. A pair of'parallel arms 1-! and Q8 project toward the right 'from the box ll] andservetoguide the matrices as'they are'inoved ".forWardly mm the bar 2 to be entered upon the ,From the foregoing it will be ,bar}. 1 As the matrices drop from the bar'3, they collect in proper compartmentsin the magazines 30, rides alongthe edge of the cam Til, therod willbe caused to reciprocate under the influence of the cam and the spring 39. It will also be understood that, as the lever 19 is moved from the,position; illustrated in Fig. 2 to that illustrated 'in Fig. 1, the plunger 15, carrying the semicircular enlargement 25, will be moved to the posin illustrated in Fig. thusbridging the gap between; the two crests Zlian'd 21. This reduces the number of reciprocations-of the rod 30 for -each rotationof the gear 9. As illustrated, the 1 cami0 is constructed to cause two complete reciprocations for each rotation offthe gea-rs. 4 Thereforathe; setting illustratedin Fig. 1 reduces the number of reciprocations of the rod's'orrom two to one for each rotation of the gear. Since the gear 9 has twice as many teeth as the gears 6,

19 is set as illustrated in Fig. 2. On the other hand, if the lever is set as shown in Fig. 1, the

. rod 30 will reciprocate once for each two turns of the feeding screws. Therefore, the finger 4|, which-causes lifting of the matrices, may be easily made to lift the matrices for each turn of the distributing screws or for every other turn thereof. Hence, if the matrices are thin, the lever l d'ma'y be set as illustrated in Fig. 2, and the matrices will be distributed rapidly. On the other hand, if a series of thick matrices are encountered, the lever l9 may be quickly adjusted to the position shown in Fig. 1, and then the matrices will be distributed only half as fast and will not interfere with each other as they are liable to do if an attempt be made to distribute a thick matrig: for eachturn of 'the distrib'uting screws.

. Brackets 53 are mounted on the frame I and support 'a shaft -56 pivotally therein. At the ends of the shaft E i are -arms"5'5 and 56 which suppoit the two end portions of the distributing screw 5. A spring hook 5"? extends through an opening in the arm '55 and latches against the front side thereof to tightly hold the arms 55 a'ndffifi and the screw '5 in position, as illustrated in Figs. 1, 2, 4, and 6. However, by pressing upwardly upon the end of the spring 51, the arm 55 maybe unlat-ohed and the screw 5 raised to the 1 position shown in Fig. 5 or anywhere between that position and the position shown in Fig. 4.

Ajb'rake 58 is pivoted at '59 and actuated into braking position by means of a spring '60. The free end of this braking member is engaged by a bar whieh is p'ivota'l'ly mounted on the frame I and extends transversely of the machine as is well understood by those familiar with machines of this type. When thiscrossbar is unlatched and "lifted, the'brake member 58 is actuated by the spring '60 about its pivot 59 and engages the "'c ollarfil 'to'put a braking force upon the shaft 1 of the 'scre'wfl, thus preventing rotation thereof.

A thrust bearing 62 surrounds the arm it between the members l1 and i3 and reduces 'to 'a the friction between these members, due to pressure by the rod 30 against the cam l0.

Fifoin the 'ioregoing'description, taken in con- "nee'uo'n With the annexed drawings, it will' be seen that I have provided a simple and'f'e'as'ily manipulates means for changing the rate oi distributibrib'finatrices 'in'a machine of the character described.
