7. Claims.

This invention relates to stationery feeding devices of the pin-wheel type, and more particularly to an. improved feeding mechanism wherein perforated superposed stationery strips are -accurately registered with each" other while engaged-by the pin-wheel.

The primary object of the invention is to provide an improved pint-wheel devicewherein perforations in the stationery. are engaged by feed pins on a wheel and the pins are-then inclined away from each other, so that the stationery, in effect, is tensione'd-between a pair of adjacent pins which engage an adjoining pair of holesin the strip. This action causes the strips to be brought into substantially perfect registration. Another object of the invention is to provide an improved mounting for the stationery feedwheels wherein the wheels, although driven from the platen roll of the typewriter, maybe adjusted bodily to and from the platen to obtain proper alignment of the stationery in writing position on the platen and keep the strips fairly taut between the platen and feed-wheels.

Another object of the invention is to provide a cam for operating oscillatable pins so that the lower side of the wheel may draw strips of stationery in one direction towards the platen while the upper portion of the wheel simultaneously draws the stationery away from the platen.

A further object of the invention is to pro-- vide an improved feed-wheel with oscillatable which is operahle to feed the stationery either forwardly or rearwardly.

The invention is illustrated in a preferred embodiment in the accompanying drawings, in which- Figure 1 is a plan view showing an attachment for a typewriting machine connected up to a rotary platen roll; Figure 2, a side elevational view of the same; Figure 3, a fragmentarysectional view, taken as indicated at line 3--3 of Figure 1; Figure 4, a vertical sectional view, taken as indicated at line 4-4 of Figure 5; Figure 5, a fragmentary plan view of one of the feed-wheels; Figure 6, a vertical sectional view, taken as indicated at line 66 of Figure 5; Figure 7, a vertical sectional view of one of the feed-wheels, taken as indicated at line |-I of Figure 3; and Figure 8, a plan view of one of the feed pin units.

In the embodiment illustrated, a supporting frame 9 is detachably secured to a. typewriting machine having a driven platen roll ll about which stationery H, provided with marginal perforations l2, may be drawn.

An auxiliary frame l3 has its side members held in spaced relation by an upper cross rod I4 and a lower cross rod IS. The ends of these rods project through enlarged slots IS in the supporting fram and are provided at their ends with nuts I! which may be tightened to hold the auxiliary frame in an adjusted position with re- I spect to the main frame 9.

As shown in Figures 1 and 2, the auxiliary frame is provided at each side with a rack gear l8 which is engaged by a pinion l9 fixed to a shaft 20' which is provided at one end with a knob 2i. Thus it will be understood that the auxiliary frame may be adjusted bodily with respect to the platen It) by loosening the nuts' I! and turning the knob 2| to a desired position where the nu can again be tightened.

The auxiliary frame is provided with a square shaft 22 which is anti-frictionally journalled in the side plates i3 and is provided at one end with a gear 23. This gear is held in mesh with an idler gear 24 on a link 25. The gear 24 meshes with an idler gear 26 journalled on a crank 21 so as to mesh with a gear 28 which makes a driving connection with a gear on the shaft of the platen roll Ill. The crank 21 is pivotally mounted on a stud 30 on which the gear 28 is journalled and secured to the supporting frame 9. Thus it will be understoodthat the auxiliary frame may be moved bodily with respect to the platen ill without interrupting the proper driving connection with the platen roll.

The pin wheels are of similar construction, and,

as shownin Figures 6 and 'i, have a hub portion 3i slidably mounted on the shaft 22 and have fixed to the hub a pair of spaced disks 32 and 33 which afford bearings for the series of oscillatable feed units 36. Each of the feed units carries an outwardly extending pointed feed pin 35 and is slotted, as indicated at 36, to provide clearance for stripper members 31. The trunnions on the feed units34 extend through the disks and are provided at one end with acam crank 38 which is secured to the trunnion by a screw 39 and is provided at the other end with a cam roller 40.

A cam member II is slidably mounted on the cross rods II and I5 and has afiixed thereto, in spaced relation, an inner cam 42 and an outer cam 43 which-provide a cam groove H to receive the rollers of the feeding units. Asbest shown in Figures 5 and 6, the stripper plates 31, which extend through the clearance slots 36 in the feed units, are also secured to the cam member ll by bolts 45 provided with suitable spacingwashers 46.

The cam groove 44; as best shown in Figure 4, is arranged so that when the feed-wheel is rotated clockwise the feed pin is inclined forwardly as it approaches engagement with the stationery II. It is then swung rearwardly along a path so that while the next advanced adjacent pin is pressing the advance side of the perforation in the paper which it impales, the following pin is pressing against the back edge of its hole in the stationery. By this action the stationery between the adjacent holes is tensioned slightly and the superposed strips are brought into substantially perfect registration.

Each of the feed-wheels is providedwith an upper and lower guide member. The guide members each have an arcuate strip 41 which has a longitudinal slot 48 to provide clearance for the feed pins 35. The member 41 is pivoted at 49 to a bracekt 50 which is secured to the cammember 4l by screws 5|. As shown in Figure 5, a spring pressed plunger 52 is secured to the member 41 and bears against a flat side of the pivot 49. Thus it-will be understood that the slotted member" may readily be turned up out of the way to facilitate loading.

After the attachment has been installed on the typewriting machine or tabulating machine, the stationery II is drawn from in rear of the machine into engagement with the lower side of the feed-wheels. The lower guide members 41 are then turned into operative position and by rotating the platen roll the stationery may be advanced down around the platen and up into engagement-with the pins on the upper side of the feed-wheels. The upper guide members I! may then be swung down into position and the device is ready to feed the stationery. If there is too no unnecessary limitations should be understood therefrom for some modifications willbe obvious to those skilled in the art.

I claim:

1. In a typewriting machine having a driven platen, a feed-wheel geared to said platen for feeding perforated stationery strips, said wheel having a series of forwardly and rearwardly tiltable feed pins to engage the perforations in the strips, and means for tilting adjacent pins in separate perforations away from each otherto cause registration of the superposed advancing strips. 1

2. In a typewriting machine having a driven platen, a feed-wheel geared to said platen for feeding perforated stationery strips, said wheel having a series of feed pins to engage the perforations, said feed pins being mounted on the wheel to tilt forwardly and rearwardly with respect to the direction of rotation of said wheel;

and means for successively tilting each pin forwardly as it approaches engagement with the stationery, tilting the pin rearwardly after engagement with the stationery to cooperate with an adjacent pin in aligning said stationery, and then tilting said pin rearwardly to facilitate'withdrawal from the stationery.

3. A device as specified in claim 1, in which the tilting means includes a fixed cam adjacent to the wheels.
