6 Claims.

This invention relates to improvements in stapling machines and more particularly to improvements in the stapling machine of the class described in the patent to Robert F. Stepbach, No. 2,303,509. 4

An object of the invention is to provide a supporting member for a stapling machine which will enable staples to be inserted through the staves, below the chime, into the had of the barrel at points in alignment with cleats which extend over the end of the barrel.

Another object of the invention is to provide a supporting segment for a stapling machine for stapling barrel heads which does not meet with interference from the cleats on the end of a barrel.

Another object of the invention is to provide a segment or support for a stapling machine which stabilizes the machine in its operation.

Another object of the invention is to provide a segment or support for a stapling machine having an improved chime engaging portion for backing up the chime when staples are being driven into the head.

Another object of the invention is to provide a structure which will hold a cleat in place on the end of the head While a staple is being driven through a hoop and an end of the cleat into the head.

Still other objects of the invention and the invention itself will become more apparent from the following description of an embodiment thereof which description is illustrated by the accompanying drawings and forms a part of this specification.

In the drawings:

Fig, 1 is a side elevational view of a stapling machine disposed on the end of the barrel and showing the relative positions taken by the various parts prior to the time a staple is driven through the staves, below the chime, of the barrel into the head, the barrel and the machine being broken away and shown in section.

Fig. 2 is an enlarged fragmentary section through a barrel showing the chime and head together with a cleat and hoop secured in place by a staple.

Fig. 3 is a view taken on the line 3--3 of Fig. 2.

Fig. 4 is a view taken on the line 4-4 of Fig. 2.

Figs. 5, 6 and 7 are top plan, side elevational and bottom plan views, respectively, of the improved supporting segment cf my invention, and

Fig. 8 is a view taken on the line 8 8 of Fig. 4.

Referring now to the drawings throughout which like parts are designated by like reference characters, the machine in its operation is substantially as shown and described in the aforementioned Stepbach patent. It comprises a supporting frame I which is arranged to overhang the chime of the barrel being provided with a shoe or segment 2 which is secured in the frame by a bolt 3 in a manner similar to that described in the patent. A supporting arm 4 extends across the barrel and rests on the chime of the barrel at the opposite side. A handle 5 is provided for actuating the stapling mechanism which drives the staple 6 through the chime into the barrel when the handle is forced downward toward the head.

Heretofore some diiiiculty has been encountered in maintaining a machine of this character in a vertical position. In actual practice the staples are driven rather quickly and very often it happened that the operator did not have the machineY disposed in a vertical relation to the head of the barrel with the result that the staple was driven into the head with one of the legs of the staple above and to one side of the other. It will be clearly seen from reference to Fig. 2 that when this occurs that the staples do not necessarily go into the center` of the head but may even miss the head entirely and extend above and below the head or be so close to the surface of the head as to split the wood.

Furthermore, with the previous device it was difficult, if not impossible, to position the stapling machine so that a staple could be driven into the head at a point in alignment with the cleats which extend across the head. It has been common practice to provide a steel cleat for extending across the head as best shown in Figs. 2` and 3 which usually comprises a sheet metal member I0 having a raised rib I I extending longitudinally of the cleat, the body of the cleat being secured to the head byv tacks I2. The end of the cleat adjacent the chime extends up inside of the chime at I4, across the top at I5, and down the outside at I6 as best shown in Fig. 2. A hoop I8 extends around the upper edge or chime of the barrel embracing the end IB of the strip. The hoop and cleat are secured in place by the staple 6 driven through the hoop, strip, the stave below the chime and into the head of the barrel.

Previously it was necessary to drive these staples by hand because the rib Il interfered with the placement of the stapling machine. This was not only a diicult operation but a timeexpending operation. By the present invention I provide a segment or support for the barrel which comprises an upwardly extending part 20 having a threaded opening 2| for reception of the screw 3 as previously described. Extending laterally from the portion 20 on each side thereof is a pair of supporting surfaces each of which comprises a flat bottom surface 23 having one edge curved to provide an arc at 24 of one radius and the opposite side at 25 curvedto form an arc of another radius. Intermediate these portions there is provided a channel 21 as best shown in Figs. 6 and 7 which separates the two surfaces 23 and extends upward toward the body 20 a suincient distance to allow clearance space for the rib Il on the cleat. The channel may be ared outwardly at the ends as indicated at 28 and 28'.

The edge walls 24 and 25 slant toward the upper side as best shown in Fig. 8 so that the bottom surface is larger than the top surface 30.

It will thus be seen that the segment or supporting member is provided with two surfaces of different curvature. This allows the supporting member to fbe secured to the bottom of the stapling machine with either of the surfaces towards the chime of the barre1 to 'provide the surfaces of different radii for engaging chimes of barrels of different size.

It will also be seen that the channel 21 allows the machine to be supported directly over the cleat and to permit driving of the staple through the hoop and end of the cleat to the barrel. During this operation the cleat is engaged by the bottom of the segment adjacent the channel 21 and the pressure of the stapling operation and the weight of the stapling machine holds the cleat firmly against the head of the barrel while the edges 24 engage the cleat at the portion I4 and press it against the inside of the chime of the barrel thus holding the cleat in a firm engagement with the chime and head while the staple is being driven in place. The slanting character of the walls 24 assures that the pressure will be exerted adjacent the head and at the base of the chime. All of these features cooperate to assist in the more firm attachment of the cleat and hoop to the head and chime of the barrel.

I also contemplate forming the channel 21 wider to enable the segment to bridge wooden cleats, which may be somewhat larger than steel cleats, when it should be desired. It should also be observed that the extension of the segment laterally is such that the stapling machine may be positioned on the barrel and it will automatically take an upright vertical position wherein both prongs of the staples are in proper alignment to be driven on a horizontal plane. In this manner proper engagement of the staple with the barrel head in the midsection is assured thus eliminating the necessity of pulling out staples and redriving which was previously a common occurrence where this Vertical stability was not provided.

Having thus described my invention I am aware that numerous extensions and departures may be made therefrom but without departing from the spirit or scope of the invention.

I claim:

1. In a stapling machine, a supporting member for said machine, comprising a shoe having a. lower face for engagement with the barrel head and forward and rearward portions shaped for engagement with barrel chimes of different diameters, said shoe extending laterally on each side from the center to hold said stapling machine 1n proper alignment with the barrel.

2. In a stapling machine of the class described, a supporting member for said machine comprising a shoe having a portion for connection to the machine, a lower surface for engagement with a barrel head, said surface being formed with a channel for the reception of a'cleat supported on a barrel head to .be secured on the end of said barrel head.

3. A shoe for use in conjunction with a stapling machine comprising a pair of laterally extending members having substantially flat bottom surfaces for resting on the head of a barrel, said shoe being formed with a channel intermediate said members for the free passage of a cleat supported on a barrel head for the end of a barrel.

4. In a device of the class described, a. shoe comprising a pair of spaced laterally extending members each of said members having a flat bottom surface for engagement with the head of a barrel, the edges of said members defining arcuate surfaces of diierent radii for engagement with the chimes of barrels of large and small diameters.
