FASTENER SUPPLYING AND DELIVERING MECHANISM.

and Delivering Mechanism, of which the .-followiiig description, in connection with the accompanying drawings, is 'a specification, like refer *nce characters on the'draivings indicating like parts-in tlie'several figures.

This invention relates to fastener supplying and delivery mechanism for fastener inserting machines. It. particularly adapted to supplying and delivering lacing hooks for boots and .shoes tosuitable hook setting devices, although. the invention is not limited in its application to that particm la-r form ofifastener.

.The invention is shown as applied to tlie machine for setting lacing hooks, illustrated and described in the inventofs co-pending.

application Serial No. 271,426, filed July 27, 1905, from which thepresent application has been divided, but the inventionisnotlimited in its use to that particular type of lacing hook setting machine. One object of this invention is to provide a .mechanism of the character described which will deliver hooks or other fasteners from a hopper to a raceway leading to the setting devices properly positioned and with sufiicient rapidity to insure that the supply in the raceway shall never be exhausted.

Another object is to provide means for releasing any hooks' which may become clogged in the hopper at the pointof de; livery 'to the raceway.

'In'aceordance with these objects. aprinhopper having therein a rotary brush adapted to sweep the fasteners from the hopper into the raceway, and means for positively rotating the brush alternatelyin opposite direct-ions through predeterininedangular distances, the angular movement imparted to the brush in one direction being greater than the movement in the opposite direction. The rotary movements of the brushin one direction thus act sweep the hooks rap- Specifloation of Letters Patent.-

idly into the raceway and the shorter reverse movements of the brush act to dislod e. hooks that may have become jammed at tl ie entrance of the raceway.

Other features of the invention, including (ertaindetails of construction and combinations of parts, will be further explained in the following description and all the features of invention will then be pointed out in theappended claims.

Thepreferred embodiment of the invention is. illustrated inthe accon'ipanying drawings, in which- ".Figure 1 is a rear elevation of the machine for setting fasteners, having in connection therewith the improved fastener supplying and deliverymechanism; Fig. 2 is a central longitudinal Section of the hopper, brushes and mechanism for actuating thebrushes to sweep the lacing hooks into the raceways; Fig. 3 is a sectional view taken on the line 3- --3 of Fig. and looking in the direction of the arrows; Fig. 4 is a front elevation of the hopper and a portion of one of the raceways leading therefrom. the end cap of the hopper being removed and a portion of the ring at the end of the hopper being broken away; Fig. 5 is a rear elevation of the hopper and of the upper portion of the other raceway. also showing the upper end of the standard in which the horizontal shaft for driving the brush actuating mechanism is journaled; and Fig. 6 is a sectional view taken on the line 6-6 of Fig. 2.

The particular type of fastener set-ting machine which may be used in connection with this invention is not of present importance. therefore, merely a general indication is given in Fig. 1 of a machine for setting fasteners, such machine being the same as that fully illustrated and described in the (yo-pending application Serial No. 271,426, to which reference has been made. In this machine the operative parts are actuated from the main shaft 20 which is driven by the pulley 86. 7

Referring now to. the features-of the present invention, a hopper 46 is supported on the frame of the machine in any conplates 45 secured at their upper ends to the opper 46, lead to the hook setting devices. The plates 45 are adapted to eriter. the space between the head and shankof a'hook, and

wise along the plates from the hopper to the setting dies. As the'hooks pass along the plates, 45 under .the force of gravity, theyare heldupon. the plates and guided by uard plates 49 arranged'at right angles 'to't e plates 45 and'separnt'ed therefrom'a suflieient' distance to form a slot to: receive the necks of the hooks. 1

The hopper 46 in which the hooksare placed loosely, and from which they are delivered to the raoewa'ys,-comprises a body portion substantially cylindrlcalin shape,

hutsmaller at the center than atthe ends, so

that the hooksplaced in .the hopper tend to fall toward the'ends, At each end of the 5 4) project, which ribs extend to the outlets hopperis arm 61 the inner-1 surface of which is cylindrical and-forms a continua-- tion of the innersurfa'ceof the body portion. From this cylindrical surface-ribs 62:(']1ig.

of the hopper and abut'a'gainst'the upper ends of theplates 45 ofthe raceways- .These ribs constitute means for properly position ing the lacing-h6oks',--the ribs entering the space between the head and base of the hooks, and guiding vthe hooks as they are swept out of. the hopper. At .the outlets of the hopper guard plates 63 are provided .which extend a short'dlstance 5 into the hopper 'over theribs62 and at their outer ends abut against the guard plates of the raceways so as to in effectform continuations thereof. The forward end of the hopper is closed by a ring' 63", and a re- 4 movable plate 64-. The rear end of the hopper is closed by a plate In these plates ashaft 66 is journaled upon which are secured hubs v67 provided with brushes 68 arrangedto pass through the mass of hooliis in 5 the lower portion of the hopper and sweep the hooks along the ribs 62 into the'raceways. p During the operation of the, machine the brushes 6S are rotated alternately in opp)? site directions, a number of revolutions mg imparted to the brushesin one direction to sweep'the books into the raceways, and then a partial revolution B emg im-' parted to the brushes inthe opposite direction to dislodge hooks which may have be comejammed at the entrance of the raceways. The mechanism for, imparting these movementslto'the brushes comprises a rotary driven member connected to the so brushes, a rotary driving member, connections between the driving and the driven members, and a cam'acting on the c0nneetrons to vary the movement of the driven member. The driven member consists of a.

gear69'meshing with a pinion 70 on the Qcam roll is traveling down the steep drop tate. loosely onthe hub of the driving memher 71. The driving member 71 is substantially cylindrical in shape, and is provided with a central web connecting the periphery to the hub, which is mounted to rotate upon a stud '72 secured in the plate 65. The connection' betwecn the driving member 71' and the driven member 69 consists of -two links .73 and 74 pivotally connected together and .pivotally connected respectively to the driving .and driven member-sf At the pointwhere the links 73 and 7-1 are pivotally connected a cam roll 75 is provided which on- 'gages a cam groove 76 l'ornK-d in the plate -65. The shape of this cam groovo is-elearly shown in 'Flg. 6, and it will be apparent from an inspection of this figure that during the greater portion of the revolution of the driving mclnher'i'l which rotateswith the arrow on Fig. 6, the cam roll 75 traveling up a gradual rise of the an: groove, and that during a small portion of the revolution of the driving member the of the camgroove. \Vhile the cam roll is traveling up the gradual rise ofthc cairgroove, the driven member 69 is given a slow forward rotation with relation to the driving member 71, so that the driven member rotates in the same direction as the driving member so long as the cam roll 75 remains on the risingportion of the'cam. When. howe \"er,thecam roll passes down-the abrupt drop of the cam groove, a rapid backward rotation relatively to that of the driving ,member is im arted to the driven member .69, which bac ward rotation is sufiiciently rapid .to reverse the direction of rotation of the brush shaft. During each revolution of the'driving member a plurality of rotations in one direction is imparted to the shaft 66 of the brushes and then a partial reverse rotation. o

The inner or front edge of the periphery -of the driving member 71 extends into close proximity to the face of the plate 65 so that a chamber is formed which incloses the gear'69, the pinion 70 and the link connections between the driving member 71 and the gear 69. In order. to providea convenient means for oiling the cam groove 76-and the pivotal connections between the links- 73 and 74,11!) opening 77 is provided in the central web of the driving member, which 120 is closed by 'a removable cover 78. The outer or rear edge, of the periphery of the driving member 71 is provided with teeth with which the,- pinion 79 meshes, through which a continuous rotation may 5 he imparted to the driving member. The pinion and the teeth on the driving member are inclosed by a casing supportedfrom one ofthe brackets in which a shaft 80 is journaled, The pinion 79 is secured upon I mince i 4 in brackets extending upwardly from -the frame of the machine. At the other end of t! a clutch mechanism by means'of which the shaft can be clutched to the pulley. The clutch mechanism may be of any well known construction and, therefore, has not been illustrated in detail in the drawings. The clutch may be operated by a rod 84 a suitable treadle mechanism in connection therewith.

YVhile in the appended claims-the term brush has been used to define the rotary device which sweeps the fasteners from the hopper into the raceway, it should be distinctly understood that it is not intendedto limit the invention to the use of a brush in the narrower meaning of, the word. In in- 2o terpreting the claims, therefore, this term v should be read in its broader sense and as inclusive of any device which may be used to perform the functions of the illustrated brush. It will beapparent that many changes in the form and construction of the illustrated embodiment of the invention'may be made within the scope of the invention, characterizing features of which are set forth in the following claims by the intentional use of generic terms and expressions inclusive of various modifications.
