STATIONERY-CABINET.

Specification of Letters Patent.

Patented May 28,1912.

Application filed November 27, 1911. Serial No. 662,617.

To all whom it may concern:

Be itknown that I, THOMAS A. Mn'r'riinws, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Stationery- Cabinets, of which the following is a specification.

My invention relates to stationery cabinets such as shown in my Patent- 748,967, Ja11u ary 5, 190%.

The object of the invention is to improve the paper-feeding mechanism shown in said patent. This object I accomplish by the mechanism shown in the accompanying drawings, in which:

Figure 1 is a perspective of my improved cabinet. Fig. 2 is a perspective of the paper-feeding mechanism removed from its casing; the paper lifter having just lifted or buckled a sheet of paper. Fig. 3 is a sectional side elevation showing the paper feeder in the act of feeding a sheet through the delivery opening. Fig. 4 is a perspec' tive of the paper lifter removed. Fig. 5 is a perspective of the bottom of the cabinet.

A designates the cabinet of any suitable material and construction and provided in its front with an opening A about as high as the ile of paper to be contained within the cablnet. The bottom of the cabinet has an inclined portion A on which the paper P rests; the high end of the incline being about in line with the lower edge of opening A and spaced from the cabinet front. The rear end of the cabinet has a door A for the introduction of the paper. Secured to the base of the cabinet at the sides and lower end of the incline A are the adjustable gages or guides A* for the pile of paper.

Within the front end of the cabinet at opposite sides thereof are vertical guides A connected at their upper ends by a cross bar A", and between these guides A slides an inner panel B, working between the cabinetfront and the front end of the incline A This sliding panel B has a horizontal slot registering with the openin A, in the cabinet front through which t e paper is fed, as will be presentl described.

The panel B is provided at its ends with uprights B having outwardly projectin notched uide lugs b at their upper an lower en s; said notchedlugs sliding on the vertical guides A. The n per ends of the uprights B are connected y a cross bar I),

and below the cross bar the uprights arc progidcd with inwardly extending brackets 04 s The sliding panel B is provided at the lower edge of its slot B with an inwardly extending flange or lip B which rests on the pile of paper, and the upper edge of the slot has a guide flange or lip B parallel with the flange B to guide the paper through the slot B. The lip or flange B is firmly held by an inclined brace 12.

C is the paper lifting arm secured firmly to an oblique shaft C, mounted in an angle bracket C secured to the inner face of the sliding panel B just above the left hand end of its slot B. The shaft C has at one end a sprocket wheel 0 actuated by a crossed chain c, the upper portion of which engages a sprocket wheel 0 carried by one end of a transverse shaft C mounted in the brackets b, b above described, and provided at its opposite end with a sprocket wheel 0 The sprocket wheel 0 is engaged and operated by a chain c", the inner portion of which engages a sprocket wheel 0 carried by a transverse shaft 0 mounted at the upper end of a standard A extending up from the bottom of the cabinet. This shaft 0 is pro vided with a bevel gear 0, which meshes with a similar gear cl on the inner end of the longitudinal shaft D, which is the 0 crating or driving shaft of the paper-feeding mechanism. The inner end of the main shaft D is mounted in a bracket a on the upper end of standard A and the outer end of said shaft extends through a bearing in the fixed front of the cabinet and is provided with an operating crank or handle D.

The lifting arm C has an anti-friction roller 0 journaled in a recess in its free end and projecting beyond one side of said arm, while projecting from the opposite side of the free end of said arm C is a friction device 0 When, therefore, the main shaft D is rotated a single revolution the arm C will be rotated toward the front of the cabinet, and when the roller 0 engages the paper the arm will act as a cam and slightly elevate the panel B, by which it is carried, and so raise the flan e or lip B from the paper, the top sheet 0 which, at its forward edge, will then be engaged by the rearwardly moving friction device 0 and moved rearwardl from under the lip B which will then escend upon the pile and the friction device will release the free edge of the buckled sheet which will then slide forward upon the upper side of the flange or lip B ready for forward feeding, as will be described.

The paper is fed by a forwardly turning curved arm or cam E secured to a short transverse shaft a mounted in the forked end 6 of an inclined arm A, the upper forward forked end of which is loosely hung on the shaft C The shaft C is provided within the upper forked end of arm E with a sprocket wheel 0 from which a chain 6 leads to a sprocket wheel 0'' on the shaft 6.

The feeding arm or cam E has a friction surface 6 of rubber or other suitable material. The inclined arm E is held from imparting its weight to the pile of paper by means of a supporting arm E extending from cross bar I) with its lower hooked end E extending under the upper fork of the arm E. The arm E is apertured for the passage of the shaft C It will be seen, therefore, that the rotation of the drive shaft will, through shaft C, which is indirectly geared thereto as described, first cause the lifting arm C to release the front edge of a sheet of paper, and that said edge will then spring forward upon the flange or lip B after which the continued rotation of drive shaft will, through the feed arm E, also geared thereto, feed the paper through the slot B and opening A in the cabinet front from which it may be pulled by the fingers of the operator.

As the lifting mechanism and the feeding mechanism are carried by the sliding panel A, the relative relation of the same to the slot A remains the same and the chain a is sufliciently slack to allow of the vertical movement of the panel A and its attached gearing. The chain 0 is held from displacement from sprocket wheel 0 by a guide arm F projecting inwardly from panel A.

An arm G in the form of a spring extends inwardly from the guide flange or lip B across the pile of paper to a point adjacent to the feed arm E, and prevents the top sheet from buckling up between the lip B and the arm E in case its front edge should not be lifted from beneath the flange or lip B at any rotation of the lifting arm C.

The drive shaft D is provided with a ratchet disk (1 having a single notch (Z engaged by a spring pawl (13* depending from the stationary top bar A". This pawl and ratchet permit the rotation of the drive shaft D in one direction only and stop it at every complete cycle of the operation. A coiled spring D on shaft D between disk (2 and the front wall of the cabinet exerts sufficient friction to prevent lost motion of the drive shaft.

H is a vertical rack bar secured at its upper angle end to the cross bar I) of uprights B and at its lower end to the bracket 6*, with its toothed edge It facin the drive shaft 1). The shaft I) is provlded with a thin sheet metal pawl cl which snaps into a tooth every time the pawl cl enters the notch d and holds the panel B with its lip or flange B slightly above the top sheet while the parts are at rest. This pawl d allows of the descent of the sliding panel as the pile of paper diminishes.

The cabinet proper may be made as in my Patents 787,966 and 787,967, if desired.
