RECEIVING-SHELF FOR MACHINES.

SPECIFICATION forming part of Letters Patent No. 641,082, dated January 9, 1900. Application filed August 29, 1899. Serial No. 728,912. (No model.)

T all whom .it may concern:

Be it known that I, ALLEN CONKLING, a citizen of the United States, residing at Chicago,

' in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Receiving-Shelves for Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a feeding device adapted to operate in connection with the delivery elements of any suitable class of machinery, and particularly with the rolls present in ironing or pressing machines, for the purpose of receiving and retaining the goods Vupon said device and discharging them therefrom or permitting the goods to be delivered to a receptacle upon a lower plane than said device.

The invention has for its object to provide a receiving-shelf having means to retain thereon the goods or articles passing through the operating elements of a machine, said shelf being normally maintained in an inclined position relative to a horizontal plane through the axis of the roll. The object of this particular structure is to prevent the contact of the ends of articles one with another, which is liable to occur when the shelf is maintained in a horizontal position and in a plane substantially that of the delivery-'point of the rolls. In such a case the ends of articles such as collars and cus upon being delivered from the rolls will strike the end of the preceding article held upon the shelf and rumple or disfigure the same, In this class of machinery it is not practicable to discharge from the table each article as it is received thereon, as there is a continuous delivery of articles from the roll, the same being fed one after another across the longitudinal length of the roll, whereby the article at one end is delivered while an article at the opposite end is being introduced. This permits the operator toiron a large number of articles and maintain a continuous operation of the machine, and as the articles pass from the delivery side of the roll they fall upon the retaining-shelf and lie one upon another, as this shelf is located below the delivery-line of the rolls.

The invention has for an additional object -io provide operating means whereby said retaining-shelf may be tilted to deliver the` goods therefrom to any. suitable receptacle communicating with the front of the machine or to permit the goods to fall from the rolls into such a receptacle.

Other objects and advantagesof the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure l represents a vertical cross-section through an ironing-machine with the invention applied thereto, 'and Fig. 2 is a plan of the same with parts broken away.

Like letters of reference indicate like parts throughout both gures of the drawings.

While it is understood that this feeding device or retaining-shelf may be applied to any desired class of machine, still for the purpose of illustration I have shown in the present instance a form of ironing-machine comprising a framework A, supporting a clothed roll A and a heated roll Athe former being mounted in movable bearings and held in yielding contact with the heated roll by means of weighted levers A3, pivoted to the frame at each side thereof, lbars A4, in which the roll A is pivoted, and connecting-links A5 between said levers and bars.

Beneath the roll A any suitableform of receptacle may be supported, such as a shelf B, having a bottom portion B inclined to ward the front of the machine and provided at the rear with bearing-brackets B2, adapted to pivotally support theretaining-shelf C. This receptacle may be supported by any suitable device-for instance, the supporting lugs or brackets B3, extending from the opposite sides of the frame A.

The receiving and retaining shelf C is constructed in any desired manner in order to retain thereon the goods delivered from the rolls, and in the present instance the same is shown as provided with side and end`walls C', so arranged as to hold the goods when the shelf stands in its normallydnclined position. (Shown in full lines in Fig. l.) The shelf is further provided with pintles or pivots C2, adapted to rest in the bearing-brackets B2, and these pivots C2 are located at a point forward of the center of the shelf, so that the IOO Weight of the shelf normally holds the same in the position shown in full lines in Fig. l and also automatically returns the shelf to this position after it is released from the tipping mechanism. As showing a desirable form of such tipping mechanism, Ihave provided a foot-lever D, provided with a step D', which lever is pivotally mounted upon a cross-bar AT, carried by the frame A and provided with a rock-arm D2, having at its upper end a slot D3. The lower face of the receptacle B is provided with a bearing-lug B4, carrying a rock-shaft A, One end of this rock-shaft is provided with a crank-arm E, pivotally connected at the slot D3, while the opposite end of the shaft carries an arm Et, pivotally connected to a link E2, which link, at its upper end, is pivoted to the retainingshelf O forward of the bearingpivot thereof, as shown at E3. vIt will be seen that a depression of the lever D will tilt or oscillate the retaining-table into the position shown by dotted lines in Fig. 1, and the slotted connection between the oscillating arm D2 and the arm E permits a proper movement thereof to exert a greater leverage from the arm D2 upon the crank-shaft and connections with the retaining-shelf.

In the operation of the device when the parts are in the position shown by full lines in Fig. 1 the collars or other articles being ironed will fall upon the table in layers one upon another and can be retained thereon until it is desired to return the same to the operator for further ironing or other purposes. When it is desired to thus return the articles, the table is tilted into the position shown by dotted lines, which discharges the articles into the receptacle B, retaining at the same time the polished or finished side ofl the goods in the same position as when delivered to the shelf. This is important :in cases where the opposite side of an article is to be polished by a second ironing operation. When the table or shelf is in the position shown by dotted lines, it will also be obvious that the collars will be delivered directly to the receptacle and not received lupon the shelf. For the reasons previously stated it is not desirable to tilt this shelf during the continuous delivery of the goods; but it is usual to wait until a number of articles have been ironed and deposited upon the shelf, when all of the same may be transferred to the receptacle, and therebyto the front of the machine.

If the shelf be tilted during the ironing operation, some of the collars or articles may be damaged, as there is a successive delivery from one end of the roll to the other.

While the mechanism for tilting the shelf has only been illustrated as applied at one side of the machine, it is obvious that the same may be duplicated at the opposite side and may also be supported in any suitable manner to effect the objects of the invention.

It will be further apparent that the device maybe applied to any class of machines where found desirable, and changes may be made in the details of construction and configuration of the several parts without departing from the spirit of the invention as defined by the appended claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
