WORK CONVEYING A'ND PRESENTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 690,416, dated January '7, 1902.

Application filed January 2, 1901i Serial No. 41,920- (No model.)

To all whom it may concern.-

Be it known that I, RUSSELL B. FULLER, a citizen of the United States, residing at Holland, in the county of Ottawa and State of Michigan, have invented certain new and useful Improvements in Work Gonveyin g and Presenting Mechanism; 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.

My invention relates to improvements in means for conveying and holding materials to be operated upon by means of various machines, and more particularly to nailing-machines, stapling-machines, and machines of like nature which are adapted to the manufacture of baskets, boxes, and like structures.

The object of my invention is to provide greater facilities for handling, assembling, and holding the material to be operated upon, wherebya number of operators may work in conjunction with a single machine, thereby greatly increasing the capacity of the same. In operating such machines in the usual way by single operators considerable time intervenes between the strokes of the machine, during which time the operatoris assembling and disposing of the work.

My invention consists,essentially,in providing improved means for moving and holding cars having holding means in which to assemble and nail the materials,consisting of tracks or ways for the cars, together with automatically-operated pawls, stops, switches, and other devices, whereby the cars are moved or held so that a number of operators may work in conjunction with a single machine, and thus greatly increase the output from the same. My device also consists in certain details of arrangement and construction hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a frontelevation of a device em bodying my invention with parts removed to show the construction; Fig. 2, an enlarged plan view of a car adapted for holding the basket-covers shown in Fig. 4; Fig. 3, an end elevation of the car, and Fig. 4 the particular form of basket-cover for which the car shown is adapted.

Like letters refer to like parts in all the figures.

A represents a nailing-machine as ordinarily constructed.

B represents any convenient number of cars of suitable size and shape and provided with devices to hold the work to be nailed, the form shown being adapted to hold basket-covers made as shown in Fig. l.

0 is a suitable track of any convenient length extending from the, elevator G to the machine A. This track should in practice be of such length that a number of persons could work at assembling the material upon the cars suflicient to keep the machine operating to its full capacity. This track should also have an inclination toward the machine to cause the cars to move forward by gravity. The bed-plate of the machine is provided with V-ways D to engage V-grooved blocks D on the cars, whereby the cars are caused to come accurately to place laterally and are firmly supported under the nailing mechanism and also by friction held from moving as the nails are driven. To longitudinally locate the cars, a pawl I is provided, which engages a projection on each car in succession, preferably the forward axle thereof. The pressure of the cars on the inclined track 0 holds the car on the machine firmly against the pawl I and runs it off the machine and upon the pivoted section F when said pawl is released.

At the side of the nailing-machine opposite t-he track O a section of track F is provided, which section is hinged to turn downward at the end adjacent to the machine. This track is raised to a horizontal position by means of a cord K, attached to some reciprocating part of the machine, preferably to the nail-basket A. The pawl I is engaged by the movable end of this section-of trackF and released from engagement with the car to permit the same to run forward upon the said section F. To insure complete closure of the section F, a contractile spring K is inserted in the cord K, which spring yields after the section is closed. To avoid premature release of the car, the end of the pawl I is turned downward and engaged by a yielding spring F on the section F. This spring trips the pawl I after the nailing operation is completed.

I is a pawl pivoted on the section F, which engages and holds the car after it runs upon the said section and until the end of the section is sufliciently lowered to connect with the upper end of an inclined track E, extending beneath the bed of the machine and the track 0 to the elevator G. The pawl I is released by engaging the support for the movable end of the section F.

G is a vertically-movable elevator operated by a cord K, attached to a reciprocating part of the machine, preferably the nail-basket A. This cord is provided with sutficient slack to permit the elevator to reach its lower position early enough to receive the car released by the simultaneous lowering of the section This cord is also provided with a spring K" to yield after the elevator has reached its upper position, and thus insure proper operation should the cord stretch. To insure sufficient movement of the cord, an arm A may be extended from the basket A, to which the cord may be attached.

Supported by the elevator G and pivoted a short distance above the same is a tilt-table H, adapted to receive the cars from the track E and also provided with a pawl I to hold the cars on the table. \Vhen the elevator is in lowered position, the table H engages a stop Jon the end of the track E, which stops the elevator and holds the table in line with the track E. As the elevator rises a stop J on the end of the track O engages the end of the table H and presses the same down against the elevator, thus tilting the table and releasing the car by engaging the pawl I with the elevator. This inclination of the table 11 causes the car to run off the table and upon the track 0. The cars thus automatically run from the machine upon the section F, are lowered upon the track E, run down the said track and upon the elevator, and are raised and deposited in series upon the track 0, from whence they proceed by gravity and in succession through the machine. At each stroke of the nailing-machine a car is released therefrom and another takes its place, being pushed forward upon the V-ways by the cars on the track 0. By stationing a sufficient number of persons alongside the track C to place material on the cars and another near the section F to remove the work from the cars as they leave the machine it is evident that no other manual labor is needed and, the machine may be worked very rapidly. For illustration I have shown a basket top in Fig. 4 made of end segments P P and two side strips Q Q and a middle strip Q. I have also shown a machine adapted to nail the strips to the segments, a car having the general outlines of the top shown in Fig. 4 and being provided with pins M, side springs N, and end springs N to hold the segments P, and also with side blocks L and spring-clips O O to hold the side strips Q, and a pin M and spring-clips O O to hold the middle strip Q; but I do not limit my invention to these particular forms. Cars of proper shape and having proper means for holding parts of boxes or other articles differing from the cover shown in Fig. 4: can readily be substituted without departing from the essence of my invention.

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