.AUTOMATIC MACHINERY FOR MAKING BASKET-COVERS.

Specification of Letters Patent. Patented Jan. 25, 191.0.

Application filed December 12, 1907. Serial No. 406,184.

To all whom it may concern:

Be it known that I, RUssELL B. FULLER, a citizen of theUnited States of America, and resident of Evansville, Vanderburg county, Indiana, have invented a certain new anduseful Improvement in Automatic Machinery for Making Basket-Covers, of which the following is a specification.

My invention relates to automatic machinery for making basket covers, such, for example, as the covers used on ordinary fruit baskets. A machine of this character is disclosed in my prior patent Number 888,989, issued May 26, 1908. It will. be seen'that the links of the endless work-carrier are provided with curved. recesses for receiving the curved cleats of the basket covers. It will also be seen that, in my said prior patent, the nailers or devices for inserting the long nails through the central portions of the cleats are located between the staplers, so that the long nails and the staples for securing the slats to the cleats are inserted in one and the same cover by one and the same operation. As hereinafter described, however, I provide means whereby the link-belts are adapted'to carry the cleats without the necessity of re ceasing the links thereof, every other link be ing of a box-like form and provided on its upper surface with vertical pins arranged in position to receive the cleatsbetween them. Furthermore, with my improved arrangement, the nailers or devices for inserting the nails or long flexible attaching devices through the cleats are arranged outside of the staplers,that is to say, at a point be yond the staplers in the direction of the travel of the endless carrier or work-holder. With this arrangement, the staplers insert the staples to secure the slats to the cleats of one cover, and at the same time the cover which has been finished, and which has passed out from under the staplers, is receiving the long nails or flexible attaching, devices. The staples and nails are thus driven simultaneously, but not in one and the same cover. While the staples are being driven in one cover the long nails or flexible attaching devices are being inserted in another cover.

In addition, the cleat-carrying links of my improved work-holder or endlesscarrier are provided with openings adapted to receive the ends of the nails or flexible attaching devices, and the sprocket wheels over which the endless link-belts travel are provided with clench-blocks adapted to deflect the nails or flexible attachingv devices and cause the same to be bent fiat-wise upon the under surfaces of the cleats of each basket cover. While the long nails or flexible attaching devices of the cover are being thus bentupwardly and flat-wise on the surfaces of the cleats, the basket covers are held down'by spring guards or pressing'devices, which latter are located practically over the sprocket wheels which carry the'said clench -bloeks. In this-way, I provide a machine which will staple together the slats and cleats of a hasket cover, insert through the cleats the long nails or flexible attaching devices, and'then throw the cover out in a finished condition and'with the said nails or flexibleattaching devices bent into position suitable for stacking the covers one upon the other, as is usual in the shipment ofarticles of this character. The nature and advantages of my invention will, however, hereinafter more fully appear.

In the accompanying drawings, Figure 1 is an end view of a basket cover machine embodying the principles of my invention. Fig. 2 is a vertical longitudinal sectionon the line '22 of Fig. 1. Fig. 3 is a horizontal section on line 33 of Fig. 2. Fig. 4; is a detail perspective view of a portion of one of the endless link-belts which constitute the traveling work-holder or carrier. Fig. 5 is a perspective of one of the completed basket covers. Fig. 6 is an enlarged longitudinal section through one end of the linkbelt constituting one side of the endless carrier, showing the sprocket wheel which is provided with clench-blocks for folding devices for inserting the long flexible attaching devices through the central portion of the cleats.

As thus illustrated, my improved basket cover machine' comprises a suitable body frame A composed of upright side castings a, and horizontal side members a .as shown more clearly in Fig. 3 of the drawings. The said'side members a are probox-like links, such as the link f shown in Fig. 4, and intermediatelinks 7, so that each link-belt presents a. practically continuous fiat upper surface. The links f are provided with upright end pins f and f outside pins f and inside pins f adapted to receive the basket cleats between them It will be seen that the cleats X shown in Fig. 5 are curved, and by referring to Fig. 7, it will be seen that these cleats fit accurately between the said pins, so that each link f is adapted to firmly hold a cleat of one end of the basket cover. Furthermore, it will be seen that these box-like links are provided with slots f adapted to receive the flexible attaching devices or long nails Y of the said covers, which are driven in the central portions of said cleats. The slats Z are secured to the said cleats and spaced apart at opposite sides of said long nails or attaching devices, the ends of said slats being curved to match the outer curvature of said cleats. The side portions a are supported at the loading end of the carrier by means of upright rods H, and the crosspiece it supports the upper strand of each endless link-belt or carrier. The castings a are connected by a shaft I which is provided with a cam z' for operating the feed mechanism of'the endless carrier or link-belt work-holder. A link i has its upper end pivoted at 2' and is provided with a roller i adapted to engage the said cam. The lower end of said link is connected with a rod 2' to which is attached a dog 2' adapted to engage the ratchet wheel i on the shaft B, and the spring 2' tends to retract the said feed mechanism. In this way, the rotation of the shaft I is accompanied by an intermittent feeding motion of the two linkbelts constituting the endless traveling work-holder or carrier. It will be understood, of course, that the shaft I can be rotated by any suitable means.

At a point where the clench-blocks (Z on the sprocket wheels D are adapted to engage the long nails or flexible attaching devices, and just above such point, are located the springy pressing devices or guards J, whereby the basket covers are firmly held down while the clench-blocks (Z on the said sprocket wheels are folding the nails Y flatwise upon the under surfaces of the cleats, as shown more clearly in Fig. 6.

The staplers K are arranged in pairs, one pair at each side of the machine, and the members of each pair suitably spaced apart to insert staples through the slats Z and into the cleats of each cover. After the cover receives the said staples, it then passes beneath the nailers L, one of which nailers is arranged over each link-belt, as shown more clearly in Fig. 7. In this way, one cover is stapled while the preceding cover is having the long nails or flexible attaching devices inserted therein, and more room -is given for the operation of the different devices,that is to say, the arrangement in some ways is more satisfactory than with the nailers arranged between the staplers. The said staplers can be of any suitable known or approved character, and are operated by the reciprocating cross-head M, which latter is connected with the shaft I by a pitman m and eccentric cam and straps m The nailers are operated by the same cross-head, so that the nail plungers N descend at the same time that the staple drivers move down to insert the staples. These nailers can also be of any suitable, known or approved character, such as shown in Fig. 8, and may have the nails fed thereto from the rocking trough or nail receptacle 0.

IVith this arrangement, the cleats and slats are inserted in the pins of the linkbelts, at a point near the shaft C, which is the receiving end of the machine. It will be seen that the pins also serve to suitably space the slats apart on the cleats of the covers, and the latter then travel forward and pass beneath the staplers. Each cover receives the staples, and afterward each cover receives the two nails or long flexible attaching devices, the endless work-holder or carrier remaining stationary long enough to permit the covers to receive the staples and nails. The covers finally pass out from beneath the spring guards or pressing devices, and they are then complete in every respect, and the long nails or flexible attaching devices are folded upon the under sur faces of the cleats, so that the covers can be stacked upon each other in a convenient and satisfactory manner, as is customary and usual for shipping purposes.

It will be seen that the cross-beams I connect the castings a at a point immediately below the staplers, and that the link-belt. supports Q are carried by the said crossbeams P and the cross-bar 71.. These supports Q carry the upper strands of the link belts, and support the latter during their forward travel. and while they are sustaining the basket covers and receiving the downward pressure of the staples and nailers.
