between adapted to receive an orienting finger,

the lugs having tapered wall structures to give strength thereto and also to centralize an orientmg finger on the cap in providing accurate alinement of the button on a support.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the. views and, in which:

Fig. 1 is a sectional view through a tack type of button showing one adaptation of my invention, the button beingshown on an enlarged scale and the section being substantially on the line 'l'--l of Fig. 2.

Fig. 2 is a top plan view of the button shown in Fig. 1.

Fig. 3 isa side edge view of the button shown in Figs. 1 and 2 looking at the left side of the button as appearingin said figure.

4 is a bottom plan view of the button shown inFigs. 1-3; and

Fig. 5. is a view similar to Fig. 3 showing a modificat-ion.

My present invention deals with buttons or fastener devices of various. kinds. and classes and, in illustrating one adaptation of the. invention, the button illustrated is of a type and kind adapted to receive a tack in securing the button to a garment or other support.

In buttons of this type and kind, quite often the surface of the button has thereon adesign, name or other type of characterization or ornamentation and, in such instances, it. is often desirable to properly position a series of buttons on the support in maintaining an alinement of the designs or ornamentations. To this end, machines attaehing the buttons employ what, is generally re? ferred to. as orienting fingers to bring the button cap or head into a, predetermined position in the machine; prior to attachment of, the button to. a support.

My present invention is more particularly concerned with button wherein the cap or head comprises a moulded or cast body of plastic or; other material andinsimultaneously formin in the moulded or cast body orienting means comprising a pair of spaced lugs protruding from the lower surface of the body outwardly of the hub or shank and, further, in forming on said lugs bevelled-wall surfaces for purposes more fully hereinafter defined. w

In Figs. 1-4 inclusive is shown one, adaptation of the invention and, in these figures, ll! represents a cylindrical hub or socket portion or member having, at its upper end, an outwardly extending annular anchorage flange H and, at its lower end, an inturned substantially conical wall 22 terminating in upwardly and outwardly curved flange portions l3. Centrally of the Wall :2 is an admission opening l4, through which the prong of a tack is adapted to pass in'securing the button to a support, as is well known in this. art. At I5 is shown a dome-shaped anvil part. The part 15 includes a. downwardly directed sleeve portion i6. arranged adjacent the wall of the huh I 8' and the sleeve portion terminates in an inwardly and upwardly inclined wall portion [1, centrally of which. is a tack receiving, opening l8. It will appear thatv the-wall portion H is arranged in abutting relation with the flange portions It, thus, forming, when the parts It? and. I5 are assembled, a large chamber, l9 in the upper portion of the hub and within the flange l l.

At 2!! is shown the head or cap of the button which is in the form of a moulded or cast body of any suitable material.

In the present construction, reference is made for illustrative purposes to plastic material and, here, it will be apparent that thermosettin and thermoplastic types of such materials can be employed. The body 20 is considerably larger in diameter than the hub Ill and has. a domed outer surface 21, a slightly bevelled inner surface 22 and a body portion 23- arranged in the chamber l9 to fi-t snugly around the anvil member [5 and, in

the hub ill, the body 23 extends below the surface 22 of the cap, as will clearly appear from a. consideration of Fig. i of the drawing.

In moulding or casting the cap or head 28-, a pair oidorwnwardly extending lugs or projecting members 24- isiormed on the surfaoezz, the lugs being spaced apart to form a socket or'recess 25 adapted. to receive the orienting ffinger of a button attaching machine. The walls of the lugs 2.4T taper outwardly, as seen at 26, to reinforce the lugs, and also to. facilitate passage of an orienting finger over the surface 22 and the lugs 24 in entering the recess 25. It will appear from a consideration of Fig. 1 of the drawing that the recess 25 extends into the body of the cap or button beyond the surface 22, as shown at 21, to provide a relatively large surface on the lugs 24 without projecting said lugs to any appreciable degree beyond the surface 22 of the cap.

It will be apparent that the recess 25 will be arranged in a predetermined angular position with respect to designs, ornamentations or characterizations appearing on the surface 2| of the cap 26, for example, the letters S C O, as seen at 28, and the word Brand, as seen at 29. In

the present construction, the recess 25 is arranged at right angles to an imaginary center line extending vertically through the two

characters

28 and 29 as seen in Fig. 2, so that these characters will maintain an upright readable position as they are arranged on the support to which the button is attached. Of course, any predetermined relationship of angularity may be provided, depending upon the machine and the work to which the buttons are attached and, in some instances, the recess 25 may be in alinement with the center of one or more of the markings on the outer surfaces of the button.

In Fig. of the drawing is shown a slight modification. In this figure, 18a represents a hub similar to the hub 20a a cap or head, generally of the form of the cap or head 20 being modified in providing a pair of lugs 24a. having a slightly conical socket or recess 25a by virtue of inwardly contracting or tapering walls 30. These Walls will aid in definitely centering and alining a button with respect to a support, it being understood that the orienting finger of the machine will be shaped to seat on the bevelled walls. In other words, with a straight wall slot, such as the-slot 25, sufficient clearance must be provided for free insertion and removal of an orienting finger, thus slight variations can be experienced in the alin'ement of the button cap. With the structure shown'in Fig. 5, a positive and accurate alinement can be'obtained. Furthermore, the bevelling of the surfaces 30 gives further strength to the lugs and will also facilitate removal of the orienting finger after the button has been attached to its support.
