J. B. LOHR CONTROL F Oct. 6, 1964 OR CARD FEED Filed March 29 FIG.
r0 Q m FIG.2
INVENTOR. JOSEPH B LOH R AGENT United States Patent 3,151,863 CONTROL FOR CARD FEED Joseph B. Lohr, Wayne, N.J., assignor to Monroe International Corporation, a corporation of Delaware Filed Mar. 29, 1962, Ser. No. 183,616 4 Claims. (Cl. 271-18) The present invention has relation to an improvement for record card feed devices of the type employed in connection with tabulating machines or the like, and more particularly to a means for assuring that record cards fed seriatim from a stacked hopper will be brought to the usual data analyzing station in a successive single order manner.
Apparatus of the above type usually comprise a magazine within which record cards are stacked and either a picker device or a feed belt card conveyor acts to feed the cards singly from the bottom of the stack along a plane normal to the stacked cards. The cards are fed from the magazine through a suitable throat opening which usually includes a cam plate adapted for guiding the card into a suitable card passage where the card is conveyed to known data analyzing devices. While the throat opening of the magazine is constructed to normally restrict passage to one card at a time it has been found that frequently due to irregularities of card thickness and to changes in the coeflicient of friction thereof caused by climatic conditions, ink dyes etc., more than one card at a time is apt to be forced along the cam plate and out through the throat opening. This, because of card overlap will cause a misinterpretation of the information thereon to occur at the data analyzing station.
An object of the present invention is to obviate such a condition by providing special card stop means to assure that only one card at any given time is moved to the analyzing station.
The manner in which the above and other objects are accomplished together with the advantages and features of the invention, will appear more fully from the following detailed description and drawings, wherein:
FIG. 1 is a left side elevation of a card hopper with the casing broken away, showing the stacked cards and card feeding devices.
FIG. 2 is an enlarged detail left side elevation showing the means for preventing more than one card at any one time from advancing to the sensing station.
FIG. 3 is a front view of the parts of FIG. 2.
The invention is shown in relation to the devices disclosed in US. Patent 2,938,667 issued May 31, 1960, to Fritz A. Deutsch and assigned to the Monroe Calculating Machine Company.
With reference to the drawings, the card magazine is formed with a base plate 11 and side guide plates 12 and 13, the near plate 12 in the drawings being cut away so as to expose the record cards 14 stacked within the magazine. Vertical end guides 15 and 16 complete the card enclosure and it will be observed that the lower terminal portion of the vertically disposed guide wall 16 terminates in a finger 17 which is angularly disposed in the direction of movement of the record cards, indicated by the arrow.
Extending beneath the cards 14, stacked within magazine 10, is a pair of horizontally disposed parallel spaced conveyor belts 1819 driven continuously by suitable means well known to the art. Finger 17 is disposed very close to the conveyor belts 18-19 but is raised slightly thereabove just suflicient to provide a throat opening through which one card at a time is designed normally to be fed out of the magazine and to the analyzing station, indicated by the sensing wheel 20.
Secured by means of studs 21 to the plate 16 and spaced forwardly therefiom by suitable spacing collars 22 is a 3,151,863 Patented Oct. 6, 1964 frame plate 23 having provided at the right and left ends thereof forwardly bent projections 24, 25 respectively. Pivotally mounted at 26, 27 upon each of the respective projections 24, 25 are similar bell crank levers 28', 29 having each an inwardly extending projection 30 overlying the card passage. Each of said bell crank levers is biased in a counterclockwise direction by respective springs 31, 32. Thus projections 39 are held normally in engagement with the top surface of base plate 11 and in manner angularly disposed thereto whereby to receive an advancing card.
As earlier described finger 17 is angularly disposed to form a cam surface in the direction of card travel and at times due to variations in the card thickness and to various inks used on the card surfaces a succeeding card is caused to be carried forward by the friction of a lead card and the succeeding card is forced downwardly along the cam finger 17 to pass through the magazine throat at the same time as does the lead card. In such an advent the upper card will now ride under the projection 30 and will be stopped by the vertical wall of plate 23 as bell cranks 28, 29 yield in clockwise direction. Thereafter as the lower card continues in movement to pass beyond plate 23 said bell cranks will depress the lead edge of the upper card downwardly and free of wall 23, so that said card will now immediately follow the lead card in proper order through the throat opening formed by said plate 23 with base plate 11.
In practice it has been found that the above described devices have greatly improved the speed in which successive cards may be fed from a magazine and also materially improves operations of the tabulating device by eliminating jamming and misoperations that otherwise have occurred heretofore as more than a single card would frequently be caused to feed at the same time from the card hopper.
Now having described the invention and the preferred embodiment thereof, it is to be understood that the invention is to be limited, not to the specific details herein set forth, but only by the scope of the claims which follow.
I claim:
1. In a record feeding device having:
means for advancing a record form,
a magazine for stacking record forms for operation by said advancing means and including a base support for the record forms,

the combination therewith of a positive stop control means comprising a nonyieldable stop member perpendicular to the direction of record feed, spaced forwardly of said throat opening in the direction of record feed and being spaced sufficiently from the base support to permit a single form at any given time to pass beneath said member while intercepting and positively stopping forward movement of any record form superimposed over the first said record form, and
a yieldable means interposed between said throat opening and said positive stop control means, in proximity to said nonyieldable member and biased toward said base support whereby to engage and depress the leading portion of any said record forms.
2. In a record feeding device having:
means for advancing a record form,
a magazine for stacking record forms for operation by said advancing means and including a base sup- 7 port for the record forms,
