Fig. 4 is a similar view showing the feeding tional machines in resorting to gravity as a kfeedmeans having advanced the button completely ing means, where the operator is working upon into its receptive socket in the jaws, and a garment or some device to vwhich fasteners are Fig. 5 is an enlarged sectional view taken to be set relatively close together, it has been transversely at the end of the button feed track found that the operator can work faster than on 'line 5-5 of Fig. 1. ` the speed in which the fasteners could be fed The invention to be described is applied to a into the jaws by gravity, and, therefore, resulted portion of the machine comprising a bearing quite frequently in a missing `fastener or -in aV block I0 supported by a head Ilrextending up- .f wardly and forwardly from a portion of the ma chine bed plate I2 which in turn may be mounted such as disclosed in the Veillette Patent No. upon a suitable pedestal or support i3, a portion 1,836,887, or operated by a, crank connection at-of which is shown in Fig. 1. Mounted- upon the tached to a clutch operated drive shaft, suchl as bed plate I2 is an anvil I4 for the purpose of disclosed in the Warner Patent No. 1,575,596. In order to overcome the above faults, it is one 45 receiving a fastener element herein described as anattaching eyelet I5. ' of the prime objects of this invention to Provide ,As a vmeans for properly positioning and retain a positive means for feeding the button elements the attaching eyelet or fastener element I5 upon into the upper jaws of the machine directly froml deformed fastener. This has been particularly true in machines that are Aeither foot-operated, the end of a raceway or feed track. ' Another object of this invention is the arrange the anvil I4 a pair of lower jaws I6 may be pro 50 vided between which the eyelet may be thrust ment of the positive feeding means and a race AWay through which the button elements 'are fed to the jaws such that the axis of the button ele-ments are arranged in a radial fan-like position and located so that the pusher means selectively 55 prior to a setting operation. These jaws I6 may be plvotally‘conne'cted as at Il to a vertical mov able slide I8 connected by means of ¿la link I9 with the forward end of a lever 20, which is adapted to be pivotally mounted upon .the ped :2,406,516 4 estal I3 and actuated by suitable mechanism of operated with the inventive features of the ma the machine to move the link I9 downwardly and chine.
