STACKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 584,842, dated June 22, 1897.

Application filed December 23, 1895. Serial No. 573,137. (No model.)

York, have invented certain new and useful Improvements in Stacking Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in stacking or packing devices.

The object of the invention is to provide a simple, durable, economical, effective, and practical stacking or packing device particularly adapted for employment in but not restricted to employment in mail-marking machines and which shall be composed of a minimum number of parts to accomplish the purposes of the device.

The invention consists in certain novel features of construction and in combinations and arrangements of parts more particularly described and pointed out hereinafter, and clearly illustrated in the accompanying drawlngs.

Referring to the accompanying drawings, Figure 1 is a top'plan View of a portion of a mail-marking machine provided with the invention of this application. Fig. 2 is a corresponding View showing the movable parts in different positions and mail-matter stacked by the stacker herein disclosed.

In the drawings, a is a front floor or table of a inail-marking machine having a receiving-way 6, closed at the front by the vertical wall CZ.

b is a guide arranged longitudinally at the outer longitudinal edge of the letter-way b. b is a follower in said way to hold up the body of letters arranged on edge therein.

The pieces of mail-matter are fed separately by suitable means to the two rolls h Z, which grip the same and discharge the letters separately in their positions on edge transversely across the front end of the letter-way c and behind the vertical front wall d.

The vertical horizontally-rotating roll 72 is arranged above the floor ct and in front of the wall d, but projecting inwardly through a slot in the said wall to approach to the proper relative feeding position with the roll Z, so that said two rolls cooperate to carry along the mail-matter as desired.

Suitable means (not here shown) can be employed to rotate the two rolls preferably in the direction indicated by the arrows on the rolls.

j is a lever arranged above the floor a and to one side of the roll h and fulcrumed at j at its front end to said floor and, preferably, so as to permit its free end to swing toward and away from said roll.

The stacking or packing device is arranged to move up behind each piece of mail-matter as it is discharged by the rolls transversely across the front end of the letter-way l) and to push each piece inwardly toward the outer end of the way and at the same time toward the outer longitudinal edge of the way, so as to aline the mass of letters in said wayagainst said side guide b and to push each piece out of the way of the next following piece.

The stacker here shown comprises a pusher 't', swingingin an approximately elliptical path into and out of the receiving end of the way I), through a longitudinal slot in the vertical wall at in front of said way.

The pusher, as here shown, is approximatelyJ or L shaped and swings in a horizontal plane above the front floor a and the bottom of the letter-way b, with its inner letter-engaging end e" (corresponding to the base or lateral extension of the letter J) rounded or curved at the ends, so as not to catch or offer any obstruction to the free passage of the mail-matter. The outer or free end i of the pusher is curved back and forwardly so as to extend intothe slot in the front wall when the pusher is operating in the letterway and as the pusheris moving toward the rear end and outer edge of said way. Hence the front extremity of the forwardly-extending end 72 of the pusher does not extend rearwardly through the wall (1 during the movement of the pusher, thereby avoiding danger of the letters being caught by said free end or extremity.

The shank of the pusher arranged in front of wall (1 is pivotally joined at 7a to the swinging link above the front floor a and 1 fulcrumed to the floor at 70 so that its free end or portion to which the pusher is joined can swing with said pusher toward and from the front end of the letter-way b.

'm is a pit-man, at one end pivotally joined to the leverj at a point between its fulcrum and free end, and from thence extending over the roll h and eccentrically and pivotally joined thereto by crank m and beyond the roll to and pivotally joined to the shank of the pusher at m The pivotal point m is so relatively arranged in respect to the pivotal points and 70 that the desired movement, as hereinafter set forth, is imparted to the pusher by the swing of the pitman through its crank or eccentric driving means or connection.

The point of connection m is here shown at an intermediate point between the fulcrum 7t and the inner letter-engaging portion of the pusher. However, I do not limit myself to such specific arrangement, as the same end can be attained by other arrangements of these pivotal points.

It should be noted that the pitman, by reason of its crank or eccentric driving connection, moves the pusher through the wall d at the inner side of the letter-way b behind the letter just discharged into said way and then moves in toward the rear end of said way and at the same time transverselyout of the way toward the outer longitudinal edge of the way, so as to press the letter usually in a somewhat inclined position in against the pack of letters and so as to leave a free space to receive the next letter entering the way. The pusher usually enters the inner side of the way, for instance, as shown in Fig. 1, and moves transversely of the way toward the outer edge in an inclined position, as shown in Fig. 2, so as to be effective in alining the letters against the outer side guide of the way.- The pusher starts on its return stroke approximately as the operating-crank m passes to the left beyond the plane embracing the aXes of the two rolls h and Z, (see Fig. 2,) and said pusher on its return stroke swings outwardly 011 its fulcrum m which fulcrum moves forwardly until the pusher assumes the position shown by dotted lines, Fig. 2, entirelyout of the way. As the crank continues around, the pusher is swung to the right and into the way at the inner side letter-engaging edge gradually assumes an inclined position and moves transverse of the way as it moves toward the outer end thereof and moves the letter laterally as well as inwardly to aline the same against the side guide or with the other letters in the way.

It should be observed that the pusher has a movable or shifting fulcrum attained by fulcruming the pusher to the swinging link It and that the crank or eccentric operating means for the pusher is provided with controlling means to carry the pusher in the proper path and to maintain it in proper positions throughout its movements. In the present instance the controlling means of the operating device comprises the swinging lever j; but I do not limit myself to such peculiar controlling means, as various other arrangements can be provided within the scope of my invention to maintain the pusher in its proper path; also, I do not limit the stacker herein disclosed to employment in a mailmarking machine, as the invention can be employed in other connections and machines; nor do I limit myself to a pusher of the peculiar shape herein disclosed, as many other shapes and forms can be employed to attain the same ends without departing from the scope of this invention; nor do I limit myself to the peculiar constructions, arrangements, and combinations of parts as specifically de scribed herein for the sake of clearness, but consider myself entitled to all such constructions, combinations, and arrangements as fall within the spirit and scope of my invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
