wonx-nocarme Davi a Application filed September This invention relates to stapling machines, especially those that are adapted for securing together two or more sheets of paper or similar articles, and has for an object to provide a simple, effective and easily adjustable stop or locating means which may be used to locate the work so that a series of staples may be set at the same distance from the edge of the article or the same distance W from the edges of a plurality of similar articles.
With the foregoing and other objects in view, I have devised the construction illustrated in the accompanying drawin forml ing a part of this specification. in this drawing,
Fig. 1 is a side elevation of a stapling machine showing my improved work locating device applied thereto, this machine being in 30 the normal position of rest. .7
Fig. 2 is a similar side elevationshowing the work in position to be stapled.
Fig. 3 is a front elevation of the device.
Fig. 4 is a front elevation of the work I6 eating element. V
gig. 5 is a bottom view of this element, an f V Fig. 6 is a front elevation and an edge view of the anvil.
This work locating device may be employed with diflerent typesof stapling machines but particularl staples either wire staples or flat staples in 5 strips, comprising a base 10 to which is hinged at ll a housing 12 carrying the usual staple driving and feeding mechanism. In this type of device. the stapledriving-mechanism is usually a verticallyv reciprocable J plunger 13 guided for movement in the whousmg and operated by a hand knob 14 which is normally held in the elevated o- I sition by the spring 15. The staples areibd to the machine through the rear end of the 5 housing on a guide bar 16 and are fed to with the type as shown for driving su stantiallyU-shaped son srarnme mandamus,

and has on one edge apair of curved notches or recesses 19 which will bend the sta 1e prongs inwardly toward each other un er the action of the plunger to clinch the staples. On its opposite edge it has notches 20 and 21 so located that when the anvil is positioned with these notches at the top the notch 20 will turn its staple prong inwardly while the notch 21 will turn its staple prong outwardly, thus giving a different set to the staples as one type of set maybe desired for certain work and; the other for certain other work. The anvil is so mounted inthe base that it may be reversed to use either set desired. It is mounted in the base by means of a pin 22 driven through the extension 18 and through an opening 23 in the anvil so that thus the anvil is pivotally mounted, and one end pro'ects beyond the side of the extension 18 to orm a'handle 24.- by means of which the anvil may be reversed sim ly by swinging this handle from one side 0 the BXtCIlSlOIl to the other.
I utilize this pin 22 as means for mounting my work locatin device. This is done by extending the pin 22 rearwardly just above the top of the base to .provide a .guide rod 25, and this rod is driven into openings in the extension 18 with a tight fit when the anvil is 'mounted.., In the arrangement shown it, therefore, extends longitudinally of the base between the top of the base and the under side of the housing. The work locating element 26 comprises a sheet metal stamped from a suitab e blank andwhen so formed is substantially rectangiece of r ular inshape with .a rectangular opening.
It is then bent or folded together on opposite sides of its mid length as. indicated at 27 thus forming an element which is of inverted V-shape, as viewed from its opposite ends as shown in Figs. 1 and 2, and which is of generalU-shape, as viewed from the front as shown in Fig. 4, thus-providing upright side portions28 and connecting base portions 29. These baseportions each have an opening 30 which are in'alignment and throu h which the rod- 25 extends with a slide is made is preferabl less spring metal an resilient of more or when on'the rod the t.'. The metal of which the element-26 v free'lower cross bars 29 tend to separate, and I therefore,- bind or cramp the opposite walls 'ofthe openings '30 on the bar to thus clamp this stop or locating element and frictionally hold a inadjiisted positions on the bar. If it is desired to adjust this stop or locating element all that isnecessary is to force it along the bar against this frictional clamping action, -or if the base portions 29 are pressed togethenit will unclamp from the ar and be easily'shifted in either direction,
but as soon as released will through its springaction tend to separate the two lower bars 29 and clamp itself to the bar in its adjusted position.
housing and the base their reared'ges will engage the front wall of the member 26 and be located in proper position for driving .the staples. It will be obvious this structure is very simple and that by forming then-0d 25 as an extension of the anvil mount, the anvil and the support for the work locating device are mounted at a single operation, thus greatly reducing the cost of manufacture, while the work locating element 26 is of itself also ver simple in construction and easily mounte in position. It is also easily adjusted and automatically clamps itself in adjusted position without requiring the use of any clamps or screws or other means which must be manipulated.
Having thus set forth the nature of my invention, what I claim is:
1. In a stapling machine, a base, a housing pivotally secured to the base, .a guide rod mounted on the base and extending longitudinally of the base, and a stop memher of resilient sheet metal bent'to substantially inverted V-shape and having a transverse recess extending downwardly from its upper edge providing upwardly extending side members on opposite sides of the housing and of a height to always extend above the lower'edge of the housing both when it is in its raised or lowered position to form limit stops for the'work, and the lower portions connecting the side members having transverse openings for the rod the walls of which-bind on the rod due to the resilient action of the metal to secure -the member in adjusted positions.
2. In a staple driving machine, a base, an anvil mounted on the base, a housing se cured to the base and carrying a movable plunger arranged to cooperate with the anvil to set the staples, a rod forming means for securing the anvil to the base and extending rearwardly from the anvil, and a stop forming a work locating element comprising a resilient sheet metal member of substantially inverted V-shape and having upward extensions on opposite sides .of the housing, and said member having transverse openings for the rod and arranged to bind on the rod due to the resiliency of the metal to secure the member in adjusted positions.
In testimony whereof I afiix my signature.
FRIDOLIN POLZER.
