FEEDER.

To a/Z wvlhninziukmwy izoiweral Beit known-that I., WILLIAM G. MAYNARD, a citizen-ot1 the United States, and a resident of Kingston,l Rondout, in the county ofUlster and State of New York;, have invented a new and AImproved Feeder, of which the following is a full, clear, and exact description.

vMy invention relates to feeders, a-nd more particularly to those adapted for use in connection with canceling-maghines.` Its principal objects are to prlovide means for secur- -ing aregular and unitary delivery of the objects operated upon.

Reference is to be had to the accompanying drawings, forming a art of this specification, in which similar re erence characters indicate similar parts in the several views.

Figure 1 is a broken top plan View of'one embodiment of my invention; and Fig. 2 is a vertical longitudinal section through the base 'at one side of the feeder, parts being brokenfaway,

'designates a base or table, upon which is mounted a holder comprising an end wall 11 and a side wall 12, situated at right angles t'liereto., both of these being preferably ixed imposition. Opposite the wall 12 is a movable? side wall 13,` having projecting outwardly from ita bracket 14, in which are Q openings to receive a rod 15, extending from `wthe;base. `A set-screw 16, threaded through the brach-eti' may be turned into contact with the rod to: retain thel wall 13. in position.

This arrangement permits the width of thel holderetobe variedI tov suit.- objects of difer-.

ent lengths.` Projecting upwardly fromfthe base, between the extremity of the wall 12 and the end wall and in Valinement with the former, are journalsv 17 and 18, thelatter beare connected by an intermediate wall 19 and have rotatable upon them rolls 20a. journal 18 also has swinging about it an arm 20, which extends toward the end wall at anvangle thereto, it diverging outwardly from the opposite wall 13. -The free endv of this arm 20 carries a pin or journal 21, to which is pivoted a second arm 22, which extends back from the end wall substantially parallel to the Wall 19. About the journal 21 may rotate `a roll 23, and at the opposite or outer end of the arm 22 are opposite elon- .gated openings 24 24 to receive journals 25 of a rol 26. Springs 27 are shown asfconnecting the arm 22 with the wall 19 adjacent to thejournaljlS, these springs exerting their Specification of Letters Patent. y

"Contacting with the inner face 'of the belt, .between the-outer roll 20a and the roll 26, is 'a roll 32, fixed-'upon a shaft 33, this shaftbeing journale'd in the base/and extending below it. Thebeltis maintained in con- .tact with this rell32 byariffoiposite roll 34,

Ou-t e 1n rotated by pinions 4g, connected by an intermediate gear 44, carried bya shaft 44, depending from the base and with which meshes a main drivinggear, a portion of which is indicated at 45. shaft 44a, below the gear 44, is a mutilated gear 46, meshing with a pinion 47, secured upon a shaft 48, rotatable in the base. This IO' shaft 48 also carries a sprocket-wheel 49, which is connected by a chain 50 with a similar wheel 51, fixed upon the shaft 33 below the base. This gearing serves to continuously rotate the feeding-wheels and to intermittently produce an outward travel of the belt.

In using the machine the objects to be fed, which may consist of letters, as are indicated at L in Fig. 1 of the drawings, are placed in the holder in a pack with the forward letter against the wall 1 1. Then upon rotating the driving-gear the feed-wheels successively advance the letters through the feed-throat,

' which presents such a space between the belt and the wall 11 that the thinnest object to be fed-as, for example, a postal card-will ust be permitted to pass without pressing back the roll 23. At the time the forward letter is projected into the feed-throat by the wheels the mutilated gear engages its pinion and inaugurates the travel Vof the belt. rI`he contact of the belt with the succeding letter, which is brought against it by the movement of the rst, holds it by the outward travel of said belt against passage through the throat,

thus preventing the simultaneous feeding of tWo of the letters. After the action of the Wheel 40a has ceased the mutilated gear passes the pinion and the travel of the belt is stopped to obviate any tendency which might exist to move the letters outwardly or rearwardly through the holder. The feed of letters is thus continued until the pack is exhausted, it being only necessary to maintain pressure upon the outer end of said pack. This `is conveniently secured by means of a pressure-head 52, having a depending portion extending through a slot 53 in the base. To this depending portion is connected a cord or flexible member 54, passing over a pulley 55, journaled beneath the base and having at its free end a weight 56.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
