S TAPLING MACHINE Filed Jan. 27, 1959 ORNEY5 Patented Oct. 8, 1940 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to fastening machines, and more particularly to a mounting for fastening machines.

It has long been a problem in the use of fastening machinessuch as stapling machines, riveting machines and similar devices-to secure a machine with which an operator would, be able to place a fastener at any desired position. This problem is caused by the necessity of mounting the machine upon a base. The area in which the machine can be used was therefore necessarily limited by the size of the base and the distance from said base of the operating mechanism. For instance, in the ordinary ofiice staplin machine which consisted of an anvil mounted on a base and a stapling mechanism and magazine mounted at the other end of the base, the length of the arm supporting the stapling mechanism limited the use of the machine, and a staple could not be placed any reater distance into the material than the distance between the mounting of the arm and the stapling mechanism.

My improved mounting makes it possible to join together two pieces of material regardless of their length or width, and to place any desired number of staples in substantially any desired location.

An additional feature of my invention is its adaptability to many uses. As an example, it is adaptable to construction work where it is customary to lay a protective paper upon newly finished concrete floors. In the past it has been necessary to glue the strips of protective paper together, being very careful to avoid any glue touching the new floor. This was a long and tedious operation, and when the paper was once glued together it could not be used again. Moreover, it was necessary to make holes in the paper in order to wet the floor in processing it. With my improved machine the sheets may be fastened together regardless of length or width by means of ordinary light wire staples. This leaves a space for the water to pass through. By removing the wire staples the paper may be picked up and used again. It will be seen that this produces a tremendous saving in materials and labor.

While in the drawing I have illustrated a stapling machine, the actual mechanism of the stapling machine is conventional and the invention is adaptable to practically any fastening medium, such as a riveting machine or a machine for inserting grommets or eyelets. It will be appreciated that the conceptive idea behind the invention is the mounting of a fastening machine upon an improved base whereby the material may be fed through the base and not limited by the size of the machine. v

In the accompanying drawing- 5- Fig. 1 shows the conventional stapling machine embodying my improved base;

Fig. 3 is a cross sectional view taken on the 10 line 33 of Fig. 1;

Fig. 4 is a detailed view in perspective of the base;

Referring more particularly to the drawing,

I employ a conventional fastening machine, such as the fastening machine I0, mounted on an arm 25 II and having the usual spring-operated magazine I2. The arm II is pivoted near its rear to a mounting I3. The mounting I3 consists of two angular members through which a pin or pintle I 4 extends. The mounting I3 is fas- 30 tened to the guide member I5 by means of screws I6, or it may be spot-welded thereto. A spring I4 rests between the guide member I5 and the arm II to normally position the fastening machine IIl upwardly. The guide member I5 is in 35 turn spot-welded or otherwise fastened to the base plate II. At the opposite end of the base plate I! immediately under the fastening machine I0 is mounted an anvil I8 to cooperate with the machine. 40

It will be appreciated that where a riveting or eyelet machine is used the anvil I8 will be replaced by the necessary cooperating means.

The guide member I5 consists of a sheet of metal or similar material bent twice upon itself in substantially an S shape to provide corresponding grooves I9 and 20. As shown in Figs, 1, 2 and 3, the sheets 2| and 22 of material to be fastened are fed through the grooves or recesses I9 and 20 forwardly toward the fastening mechanism 50 III. These sheets are fed into the rear 23 of the guide member I5. As they emerge from the front 24 of the guide member I5 they overlap and are joined together over the anvil I8 where the machine may be operated by pressure on the 55 operating handle 25. It will be seen that the continuous sheets of material 2| and 22 may be fed through the rear of the base member andv fastened together by staples 26 or other fastening means.

Since in many instances it is more convenient to move the machine rather than the material, the base plate I! may be curved upwardly slightly at either end 21 or 28 to facilitate its movement. When the machine isused in fastening long strips of material and it is desirable to move the machine rather than the material, a' supplemental handle 29 (as shown in Fig. 6) may be added. The handle 29 may be'of any convenient shape pivoted to the pin l4 and having a contacting surface 30 adapted to engage the operating handle 25, 1

In many instances it is desirable that the fasteners, especially where staples are used, should be placed parallel to the junction of the material rather than at'right angles thereto. In such instances themagazine [2 may be set at right angles'to the base plate IT. This may be done by mounting an angular arm 3! on the guide member l5 and operating the conventional fastening mechanism from-the outer end 32 thereof in the same manner as previously described.

, It will be appreciated thatthe depth of the grooves l9 and 20 may be varied in accordance with the-use'to which the machine is'to be put and that supplemental means, such as guidesmaybe inserted in the grooves to decrease the depth thereof and thus control the overlap of the material. 1 It will also be appreciated that the grooves lfl and 20 may be made of any reasonable depth and may be extended to allow the passage of a sheet of any desired width. This would of course necessitate the guide member I5 being of a greater width.

I claim:

1. A fastening machine comprising a plate, a guide member substantially S shaped in cross section mounted at one end of said plate, the open sides of said 8 being on the longitudinal axis of said plate, a fastening mechanism mounted on said guide member, and an anvil cooperating with said fastening mechanism at the opposite end of said plate.

' '2. A fastening machine comprising a plate, a guide member substantially S shaped in cross section mounted at one end of said plate, an

' angular arm extending from said guide member, an anvil mounted at the opposite end of said plate, and a fastening mechanism mounted on said angular arm and cooperating with said anvil to fasten material fed through said guide member and across said anvil.

3. A fastening machine including a base, a guide member substantially S shaped in cross section mounted at one end of said base to allow the passage of material therethrough in overlapped relation and in a direction parallel to the longitudinal axis of said base, an arm pivoted to said guide member, a fastening mechanism mounted on said arm, and an anvil at the opposite end of said base cooperating with said fastening mechanism.
