Specification of Letters Patent.

Patented Mar. 27, 1917.

To all whom it may concern:

Be it known that I, ALBERT WV. BUEHLER, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Button-Placing-Finger Control; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to shoe button fastening machines, and particularly to means for raising the button placing finger from button engaging position during each return movement thereof, and has for its ob ject the provision of simple and improved means for this purpose.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which' Figure 1 is a front top perspective view of a machine embodying the invention, with the operating parts in normal position. Fig. 2 is a different perspective view thereof, with the button placing finger in engagement with a button and at the limit of its button placing movement, and Fig. 3 is a side elevation thereof, with the button placing finger partially retracted from button setting position.

Referring to the drawings, 1 designates the customary button placing finger for machines of the character described, which finger pivotally projects forward and downward from the upper end of a rocker-arm 2, the finger being yieldingly retained in lowered button engaging position by a spring 3, as is well understood in the art.

The wire feed lever 4 of the machine is pivoted to the frame-head 5, as at 6, and carries a jaw 7 at its outer end for coacting with the lever end to releasably grip a wire 8 to effect a predetermined forward feeding movement thereof at each stroke of the lever, as is common with machines of this class.

A cam-plate 9 is hinged, as at 10, to the forward end portion of the frame-head 5 for vertical rocking movements relative thereto. This cam-plate, when lowered from the elevated position in which it is normally held by the spring 11, is adapted to ooact at its forward end with a finger 12 on the wire gripping jaw 7 at any point in a movement of the. jaw to release the wire 8, as is fully described and claimed in application Serial No. 68,868, filed December 27, 1915, by Le- Dru R. Pomeroy.

The cam-plate 9 has an inwardly extending arm 13 at the end thereof adjacent to the button placing finger .1, and the free end of' this' arm is transversely angled to form the rearwardlyinclined cam surface 14: under the placing finger 1 between the ends thereof.

Should the button placing-finger l have a forward button placing movement when a button is not in engagement with its lower end, the finger will swing downward sufficiently for a shoulder or tooth 15 on the lower edge thereof to engage the upper rear edge of the cam surface 1& and cause a forward rocking of the cam-plate 9 during the continued forward movement of the finger. It will be understood that this movement of the cam-plate elfects a release of the wire feed jaw 7, as fully described in said former application.

A feature of the present invention consists in pivotally mounting a dog 16 in normally pendant relation on the placing finger 1, which, in a forward button placing movement of said finger, is drawn over the top of the cam surface 14.- and then drops in pendant relation in advance thereof, as shown in Fig. 2. A lug 17 projects from the upper inner end of the dog 16 over the top edge of the finger and coacts therewith to limit the forward swinging movement of the dog with respect to the finger, as is apparent. On the return stroke of the placing finger the lower end of the dog 16 engages and rides up the cam surface 14 and raises the finger so it will not drag against the next button in order, as shown in Fig. 3. The dog passes over and drops at the rear side of the cam surface 14: by the time the finger has returned to the limit of its rearward stroke, thereby permitting the nose of the placing finger to lower into engagement with the top of the next button to be fed forward.

It is evident that I have provided simple and efficient means, for use in conjunction with the button placing finger and wire feed stop means of a button setting machine, for automatically raising the placing finger from button engaging position at each retracting movement thereof.

I wish it understood that while I have particularly described and shown my invention, I do not wish to be limited to the specific construction, arrangement or form of the parts or elements shown, as it is capable of numerous modifications without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine of the class described, a button placing finger, wire feed release means, and means coacting with said finger and first means to cause a raising of the finger from button engaging position during a retracting movement thereof.

2. The combination with a button plac ing finger in a machine of the class described, of an inclined cam surface below said finclined cam surface below said fingerint'en mediate its ends and having predetermined movements imparted thereto by said finger 7 when the finger is moved forward free from engagement with a button, and a odog pivoted to said finger for limited swinging movements relative thereto. and operable at each rearward stroke of the finger to coact with said cam surface and raise the'finger from button engaging position during a portion of such rearward stroke of the finger.

In testimony whereof I have hereunto signed my name to this specification.

ALBERT w. BUEHLER.
