Be it known-that I, WILLIAM A. BERNARD,

a citizen of theUnited States, residing in;

for applying or-settingstaples and like fasn teners, and it has particular reference to hand tools designed to apply buckles-and bows to shoes by means of: thesmall staples which aregenerally used for this purpose. The invention other uses. a v r The primary object which I have inview is the provision of an efficient, reliable device for driving or pushing a staple through a plurality of superposed layers of material, andthen' clenching the ends of'the, staple in thematerial so as to'form a strong, tight connection between the, layers; 5

Anothenobject is to provide a device which, can be very conveniently operated, inasmuch as-means are provided for receiving and retaining the staplein the proper positionpreparatoryto and durin the piercing, and clenching operation, without the'necessity of exercisingvspecial .care in positioning the staple oroperating the 'tool ordevice. r

I also aim to providera staple applying device in which the staplecanbe set-indifferent positions relative tothetool, without adjustingthe latter. Moreparticularly, it is aimedtfo provide a] tool in, which the staple when in position for application to, theshoe or other article, can be directed eitherlongitudinallyortransversely of the toolso that it can be placed in'the mostadvantageous position-on the article applied.

to which it is to be To these and other ends,- the invention consists in the novelfeaturesfand combinations of parts to be hereinafter 1 described and claimed. v i

of other types. In the form shown,:the tool comprises crossed lever members lO, 11 piv-.

oted together at-12, and parallel jaws-'13, 14 movable toward and away from each other. The aw,14 is equipped-with a member 15 for driving the staple through the material, and associated with saidmember is a staple openingin the j aw:14. "It serves as a guide for the holder 16, which-is in the form of a sleeve embracing the driver and vertically movable with respect thereto. 3 The opening through the sleeve-like holder conforms closely to the driver, and therefore, in the present case, it is also square in cross section,

as-shown in Figs. 7 and-8." 7 a The holder.16 is yieldingly mounted relative to the; driver by .inea'ns of the following mechanism: Depending 1 from the holder sleeve; at opposite sides-are cheeks or arms 18 which are guided vertically on the 1 jaw 1i by engaging guide grooves 19 on opposite enlarged section on line .Fig. 7 is a planfiviewof aportionofthe:

sidQiQf the'jawt The lowerendsofthe arms 1 18 are interconnected by means of a transverse pin 20, engaged by a leaf sprmg '21 which may be conveniently attachedto the against the top surface ofthe driver and its leg portions held upright by engaging the corners 24 of the square sleeve opening, as shownin Fig-8. The-staple fits said open ing rather'closely so that when the staple is dropped into the holder it will be held in a position to-cooperate with the anvillll', as hereinafter described.- V

In the present example, aspecialform of stop is used-to limit the'upward movement of the holder (under the influence off'the spring), relative to the driver. A Ushaped member 25 preferably made of sheet metal" is pivoted on the pin 20 between thecheeks or. arms 18 oflthe staple holder,- and is provided with surfaces to abut the" lower portion of the j ant-14. Intheform shown, the bent up SlClB'DOlblOIIS 'of the member 25 are perforated for the reception of the pin '20, and are provided with- =edge portions 26 whiehabut the lower surface of the aw 14 when the parts are in the position shown in Fig. 2, and therebylimitthe upward movement of the holder. The; member 25 is provided with a thumbpieceor manipulating handle 27', by which it maybe swung about the pivot'20 into-the position shown in Fig. 5. In this last position, the edge portions 28 at the ends of the bent'up side members engage the lower-surface'of the jaw 14 and holdthe holder 16 in a: depressed position. In other words,;the member '25 acts'in the nature of a cam which,-when swung into one position, will force the holder downward withreference to the driver and maintain it in-that position. Inthismanner, the

pocket formed by the cooperation of the driver and the holdermay be varied-in depth as desired. Where it is :found that the holder 16, when in its uppermost position- (Fig. 2) is too close to the anvil for the ready and convenient insertion of the staple, it-may be easilylowered' into the position shown in Fig. 5 by swinging down the thumb piece 27 so that theho'lder' will then be more freely accessible. I

Inthe operation ofthe device, the staple is placed in position, as shown-, for example,

in Fig.2. The layersfof material "to be united-Care then interposed between the holdervandtheanvil, :and thejaws 13; 14

are .approached toward each other by means of the lever handles. First, the member 15 drives the staple upward through the lay- .ers of material. During this part of the operation, the staple isfirmly held on top'of the driver in the proper position by means of the holder. As the free ends of the staple pass completely through the uppermost layer, they come into contact with the die 17 and are thereby turned over and, down- 81, and the spring 21' returns-the holder 16 to its normal position. i It has been assumed that in the foregoing ;operation, the "staple engaged the front and rear corners 24 of the holder so as to have theplane 'ofthe staple in the plane of the tool. If desired to set-the staple transversely of "thetoolgit is engaged in the other corners 29 of the holder, as shown in Fig. 7 It will be noted that one of the diagonals of the holder opening is disposed transversely: of the jaw- 14, while the other diagonalis disposed longitudinally of said jaw. The depression or clenching surface 30 of the anvil -17 iscrossshaped, so that the anvil will properly clench the staple when the latter is set either longitudinally :or transversely-relative to the tool. Thus it will be :understoodthat the staple can beset when in" different angular-relations relative to the axis of the driving member. In some cases','the staplecan only be setin ora-pplied' to theshoe Or -other article in-the most advantageous position by disposing it lengthwise of the jaws,*but, in other cases, the desired result can-only be obtained if the staple isdisposed'trans versely of the jaws. My improved tool takes care ot-both of'these conditions, and provides means for clenching a staple seatedin a rectangular holder opening coincidentally withone or either of the diagonals of said o ening. I

It will be observed that th e driver 15-is in theform of a prism, which, in the example shown, is of uniform cross sectionthroughout that part which is engaged by the sliding holder 16. Furthermore, the cross section-ofthe driver is'that of a] convex polygon, i. 6., one without reentrant angles,- and the polygon is a regular polygon, 216., one in which all the sides and angles are equal. The open-ing'in the bottom of the holder is of the same cross section as theiopening through the remaining portion of the holder body, so'that the holder conforms toihe driver throughout the -1ength-of'the former.

renders the manufacture of the driver and.

cooperating holder a very simple matter, at the same time that it provides for the seating of the staple in either of two positions in the rentrant angles of the holder which conform to and guide the holder on the projecting angles of the; driving member.

Of course, I do not limit myself in all aspects of the invention to a construotionin which the holder has only four seating 'cor--.

ners for the staple, for obviously, the number might be varied without departing from the scope of the invention. Various changes in this and other respects may be adopted within the scope of the appended claims.
