BASKET-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 516,276, dated March 13, 1894- Applioation filed August 16, 1893. Serial N0- 483,Z 70. (N0 model.)

To all whom it may concern:

Be it known that I, LUTHER PALMER, a citizen of the United States, residing at Dexter, in the county of Washtenaw and State of Michigan, have invented certain new and useful Improvements in Basket-Making Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in the peculiar construction, arrangement and combination of the various parts.

My machine embodies a frame, a table slidingly supported in the frame and carrying a rotatory form or anvil, means for revolving the form or anvil automatically, and a tack feeding and driving mechanism.

My invention comprises the combination of these various instru mentalities in a single machine and the details of construction of the various parts, all as more fully hereinafter described.

In the drawings, Figure 1, is a perspective View of the top of my machine. Fig. 2 is a vertical, central, longitudinal section therethrough. Fig. 3 is a top plan view thereof. Fig. 4. is a perspective view of the former or anvil particularly illustrating the mechanism for rotating the same. Fig. 5 is an enlarged plan view partly in section of the lower end of the tack chutes illustrating the manner of cutting 0E and feeding the tacks to the drivers. Fig. 6 is a similar view showing the parts in different positions and illustrating but one of the pair. Fig. 7 is a longitudinal section on line a: a: in Fig. 6. Fig. Sis an elevation of the end of the hammer. Fig. 9 is a sectional elevation illustrating the construction and operation of the inner hoop holder. Fig. 10 is a perspective view of the clamping band. Figs. 11 and 12 are views illustrating the material employed in manufacturing the box.

A is the frame of the machine,'B are the longitudinal timbers at the top thereof having guides B on the sides engaging with the guides O, of the timbers O forming the main timbers of the reciprocating table.

D is the table top secured upon the upper faces of the timbers O, and E is a connecting bar or board connecting the under faces of the timbers C, the whole forming a sliding table moving in guides on the stationary longitudinal timbers B which in turn are supported upon the frame of the machine.

E is a vertical shaft journaled near the forward edge of the table in the top and bottom cross timbers thereof and carrying at its upper end a suitable form or anvil F above the table top, the form or anvil being of the shape of the basket which is to be manufactured.

The basket is made from two or more strips of veneer, such as is shown in Fig. 11, marked G, which are crossed centrally and secured together, as shown in Fig. 12. These strips are usually scored centrally of the ends, as shown at G. The strips thus secured together are shaped upon the form and the inner and the outer hoop arranged thereon in the following manner. The first step in the operation is to place the inner hoop G2 about the base of the form, as shown in Fig. l, the ends engaging between the hoop holder G and the form. (The construction and operation of this hoop holder will be described further on.) The veneer pieces secured together, as shown'in Fig. 12, are next placed upon the form, and the clamping hoop H is forced down over the ends, causing them to be bent downward over the sides of the anvil and bind them tightly upon the inner hoop. The outer hoop is now placed about the veneer, beneath the clamping hoop H, as shown in Fig. 4, and the button H on the clamp band is turned over the overlapping ends of the outer hoop. In this position all that is required to complete the box is to tack through the hoops and the ends of the veneer. To accomplish this the table is moved to and from the tacking mechanism by means of the lever I pivoted at the rear of the machine and extending to the front edge thereof in suitable proximity to the foot of the operator.

The depression of the lever throws the table forward by means of the'following mechanism: I is a connecting rod secured at one end to the lever and at the other end to a crank I which is secured at the end of the shaft J. This shaft carries centrally the crank arm J, which at its lower end is provided with an antifriction roller J 2 bearing against the rail J 3 on the post J 4 depending from the under side of the crossbar E of the table.

The rocking of the bell crank J will cause the roller J to force the post and with it the table toward the tack driving mechanism. The forward movement of the table retracts the inner hoop holder G by the mechanism shown in Fig. 9. The hoop holder consists of a wedge shaped finger projecting through a slot M in the table and at its lower end, provided with an off-set M engaging in the cam shaped guide way N formed on the inner face of one of the stationary bars B, so that the forward movement of the table will cause the off-set to move down through the inclined portionof theguidewayand retract the fingerf rom the hoop. L is a spring acting with its tension to return the carriage to its initial position. In the return movement of the table the anvil is rotated a quarter of a turn, by means of a spring pawl K, engaging with pins K on the plate K secured to the lower end of the shaft E which carries the anvil, as plainly shown in Fig. 4. L is a spring bar adapted to bear against the squared face L of the plate K to hold it and the anvil in its adjusted position, so that the hammers will work squarely against the flat face of the box.

The tacking mechanism is actuated by the movement of the table and it is substantially of the following construction: 0 is a cross bar secured on the stationary longitudinal bars of the frame. Upon the upper face of this bar and opposite the anvil are secured the guide plates 0, in which slidingly engage the hammers or drivers 0 These hammers at their rear ends are connected together by a cross bar 0 and are held normally retracted by the tension of the spring 0. They are driven forward by the forward movement of the table through the lever O which bears against the rear face of the cross-bar O and which is actuated by the arm P extending forwardly from the post J 4 at the forward end of the table. These hammers or drivers I make of magnetic iron, so that they will attract the tack and hold it thereon while the end of the hammer passes beyond the guides, as shown in Fig. 8 and during the time it is being driven. The tacks are fed to the guides from the receptacle P which is secured on a frame P pivotally secured to brackets on the cross-bar O. This frame at its rear end is supported upon the notched wheel Q which in turn is supported upon the frame Q which is hinged at its forward end to the cross-bar P and at its rear end is supported upon the adjusting bolts R, which rest upon the top of the stationary frame, so that by adjusting the frame Q vertically the angle at which the receptacle P stands may be varied. S are guide strips in the receptacle to guide the tacks into the guide slot S. Upon each side of the guide slot are guide ways S which terminate above the chutes T, leading to the guides in the guide plates 0 slightly in front of the normal position of the drivers T is a cut-off plate having the inclined grooves U formed therein,terminating 1n the enlarged feed aperture U and forming the needles V which are oscillated across the lower end of the feed chute for the purpose of feeding a single tack at a time into the chute T. The notched wheel Q is rotated by the reciprocations of the table by means of the pawl a carried on the bell cranlclever b, which is provided with the anti-friction rolls 0 bearing against the inclined face at at the forward end of the rails O of the table. '1 he forward movement of the table causes the spring pawl to turn the Wheel, as plainly shown in Fig. 2, agitating the frame P and the receptacle P and causing the tacks to move toward the lower end of the receptacle. The needle bar or cut off T is actuated by the spring d secured at one end to the frame of the machine and at the other end to the bar. The bar is provided with a depending roller 6 extending beside the outer face of a block secured to one of the rails 0 (lot the table, which is provided with a cam or lnchne f so arranged that in the forward movement of the rail G, the roller e rolls up the incl ne f and moves the bar laterally to the positlon shown in Fig. 5 allowing a tack to run down in the guide way S beyond the point of the needle V in the return of the table and the drive mechanism. The spring (1 draws the cut-01f bar down the inclinef moving thebar laterally in the opposite direction, to the position shown in Fig. 6, until the enlarged feed aperture U registers with the mouth of the chute T, allowing the tack which has been cut off by the needle V to fall therethrough and into the guide way in the block 0.

It is obvious from the description given that as the table with its anvil is moved forward toward the driver that the hammer will simultaneously move toward the anvil carrying with it the tack as described, and the tack will be forced through the hoop and veneer of the box and clinched upon the inside. As the table returns to its initial position by the spring L the anvil will be rotated a quarter of a turn presenting a new face to be tacked in the next forward reciprocation. This operation is continued until all four sides of the box have been operated upon when the clamping hoop and box are removed and the operation repeated.

While I have shown my machine applied to manufacturing a four-sided berry box or basket, I may use it in manufacturing berry or other baskets of any desired shape, round, hexagonal, &c.,the form or anvil being made of proper configuration.
