ARTHUR BATES, OF LEICESTER, ENGLAND, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

' MACHINE FOR HANDLING ARTICLES.

To all whom it may concern:

Be it known that I, ARTHUR BATES, a sub ject of the King of England, residing at Leicester, in the county of Leicester, England, have invented. certain Improvements in Machines for Handling Articles, of which the following description, in connec tion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This'invention relates to improvements in machines for handling small articles such as eyelets, lacing hooks, studs or similar articles and particularly to machines of'the above class that are adapted for delivering such articles in predetermined position to a suitable receiver.

While the invention in its broader aspects is applicable to machines intended for handling articles of diverse forms and use, the machine illustrated in the drawings and hereinafter more particularly describedas embodying such invention is especially adapted for arranging, lacing hooks and delivering them to a suitable holder as one stepin the manufacture of such hooks.

In the manufacture of lacing hooks it is customary to arrange the blanks after they havebeendied out and bent to substantially their final, form in predetermined position in a suitable holder or carrier which holds them firmly during-the process of applying a coating of celluloid, pyroxylin, or other wear resisting material to their heads. Further steps in the manufacture of the hook consist of applying a sheet of celluloid or other wear resisting'material to the heads ofthe hooks positioned in the holder and in applying a matrix provided with recesses shaped and positioned to correspond to the arrangement of hooks on the holder to force the celluloid into position and to secure it to the hook. These steps, however, form no part of my invention and are not further described. p

The principal object of this invention relates to the provision of a machine adaptedto position small articles such as lacing hooks and to feed them to a suitable holder in proper position and arrangement to be received thereby, thus avoiding the necessity of positioning such articles and varranging them in the holder by hand.

An important feature of this invention Specification of Letters Patent.

Patented June 8, 1915.

Application filed April 13, 1908. Serial No. 426,865.

is the provision in a machine of the above type ofa raceway and a holder so disposed "with relation to each other that movement of one relative to the other causes a series of the articles to be delivered from the raceway upon the holder in regulated order. Preferably a mechanism isprovided that automatically controls the number of articles that shall be delivered to the holderat each operation of the machine and there may be means for readily adjusting said automatic mechanism to vary the number of articles that are automatically delivered.

A second feature of this invention is a construction in which movement of the holder to-its position to receive the articles causes mechanism to be actuated for automatically delivering thereto a predetermined number of articles, and a third feature relates to the construction of the holder by which it is adapted to engage the articles while they are still in position on the raceway and positively to remove .them therefrom. Preferably a portion of the raceway may be so constructed and arranged that the articles when traversing such portion shall have such portions as are to be engaged by the holding means on said holder spread apart to a distance substantially equal to that between the saidholding means. With this construction the relative movement of the carrier and raceway and the movement of the articles along this portionof the raceway will cause said holding means and articles to register successively and therebyinsure that the articles shall be delivered to said holding means on the holder with precision and despatch.

The means by which this result is accomplished constitutes another and important feature of the invention.

Still another feature of the invention relates to the provision of means for locking the articles delivered to the carrier in their proper position thereon, and means for automatically actuating said locking means when the carrier is brought into position to receive articles 'or is removed from such position.

. Referring now to the accompanying drawings which represent a preferred embodiment of this invention in a machine especially adapted for handling lacing hooks, and in which Figure 1 represents such a machine and holder member in side elevation, partsbeing shown as broken away; Fig- 2 is a .plan view showing the machine with parts broken away and the upper part of the machine in section; Fig. 3 is a transverse section of the raceway showing the hooks in position thereon and illustrating the action of one of the detents; Fig. 4 is a longitudinal section of the holder member showing the manner in which the hooks are removed from the delivery end of the raceway; Fig. 5 is a plan view of the holder member; and Fig. 6 is a transverse sectional view thereof.

On the drawings, 2 represents the frame of the machine which supports at its upper end a hopper 4 within which the hooks are placed in bulk and from which they descend by gravity to the drum 6 which contains any usual or preferred mechanism for delivering them in proper position to the raceways 8. The particular form of mechanism for delivering the hooks in proper position'that is illustrated in the drawings comprises two plates 10 secured to a spindle 11 that is mounted in bearings in the drum 6 and'rotated intermittently by suitable con- .nections, with a main shaft 13, such as, for

instance, a lever 14 operated by a cam (not shown). on said shaft and connected to-a carrier 16 for a pawl 18 which engages a ratchet wheel 20 mounted on the said spindle 11. To prevent breakage in case the plate 10 should be jammed by'the mass of hooks in the drum 6, the connection between the spindle and ratchet wheel is preferably of a. frictional or otherwise yielding character. As shown, this connection comprises a spring 22 thatreacts against a nut 23 'on the end of said spindle to press the ratchet wheel 20 against a shoulder, not shown, on the spindle. so that the spindle and ratchet wheel normally rotate together but are capa bl'e of relative movement should the rotation of the spindle be for any cause retarded or stopped. Each plate 10 is cut away to form one or more portions 24 which, asthe. plate rotates in the direction indicated by the arrow a in Fig. 1, engages some of the hooks in the drum 6 and carries them along until one edge of said portion is in alinement with the raceway 8 when the'hooks pass from said cut-away portion 24 to the upper end of the raceway, a suitable aperture being provided in the casing of the drum 6 to permit the hooks to pass. As shown in Fig. 2 the plates 10 are arranged in close proximity to the sides of the drum 6, the space between each plate and the adjacent side of the drum being slightly greater than that occupied by the head of a hook but considerably less than that occupied by the shank so that each plate shall pick up and deliver to its cooperating raceway hooks having their heads extending only in onedirection and it'shall be impossible for a plate to pick 27 and may be locked in closed position by a spring-pressed bolt 28.

As indicated in Fig. 2, two raceways'8 are provided, one cocperating with each of the plates 10, and each is provided with a guard 30 for preventing the hooks from falling ofi. Each raceway is twisted through an angle of substantially between its receiving and its delivering ends andapproaches its companion, see; Fig. 2, while at the same time the guards 30, which are likewise twisted so as to maintain unaltered their relations to the raceways, are merged intoa single bar 32, as shown in Figs. 1 and 3.

' A holder member 34 hereinafter more particularly described is mounted to travel in guideways formed in the frame 2 immediately below the delivery end of the raceway. The holder member has recesses 35formed therein to receive the hooks at the end of the raceway and remove them positively therefrom. To insure the correct presentation of the hooks to the holdermember a portion of the raceway near its delivery end is bent to a curvature such that, as, shown in Fig. 4, the shanks of the lacing hooks 36 when traversing said portion shallbe spread apart a distance substantially equal to that between the recesses or other holding means 35. With such a construction it will be readily apparentthatwhen the holder member moves in'the direction indicatedby the arrowvbon 'Fig. 4 the recesses 35 will register successively with the hooks on the raceway and will positivelyremove them therefrom. To obviate the possibility of the hooks striking the edges of the recesses 35, each recess is 2 erally from the raceway before they are fully engaged by the recesses of the holder member. i

When the holder member 34 is'inserted in the machine it engages the head 40 on a slide 42 which is mounted in guideways in the frame 2 0f the machine immediately beneath the path of said holder. Slide 42' is normally held toward the front of the machine by any convenient means such as the weight 44, which is secured thereto by a flexible connection passing around a pulley, as shown 1n Fig. 1. Sald slide is however adapted tobe moved by the operator to the rear of the machine in which position it engages-catch 48 at one end of a member 50 supported by the pins 51 and 53 taking in the slots 55 and 56 and provided with a de tent 52 extending normally in position to prevent the flow of hooksdown the raceway. The engagement of catch 48 by slide 42 moves member 50 to the rear and removes the catch 48 on the end of member 50 a.

spring 54 moves said member to again bring the detent 52 into the position shown in Fig. 1, stopping further delivery of hooks from the raceway. The position of the detent 52 with relation to the raceways 8 is such that the number ofjhooks that are permitted to flow down said raceways on each actuation of the machine is just sufficient to fill all the recesses in the holder member 34. It is sometimes found desirable, however, to employholders that differ from each other in regard to their capacity for holding hooks and accordingly the machine is shown as provided with means for adjusting the member 50 to determine thenumber of hooks that are permitted to flow past the detent at each operation, of the machine according to the holding capacity of the holder member that is inserted in the machine. To permit the said member 50 to be adjusted readily for the purpose above set forth, slot 55' is connected with a second slot 57 which, when brought into engagement with the stud 51, so positions the member 50 that the detent 52 is'withdrawn from the raceways anda second detent 60 is moved into coiiperative relationship therewith while a second slide engaging catch 62 is moved into the path of slide42. When it is desired'to fill a holder memberof the maximum holding capacity, the member 50 is adjusted to bring the detent 52 and the catch 48 into coiiperative relationship respectively with the raceways Sand the slide 42, while if a holder member of a smaller capacity is to be filled the member 50 is so adjusted that the detent 60 and catch 62 are in operative relation. If desired, the detents 52 and '60 may be secured to the member 50 by screws extending through slots 61 inthe said detents and screwing into the member whereby a finer adjustment of thedetents with relation to the raceways may be obtained. The slots 55, 57 may also be provided with an enlargement 63 of a size suflicient to allow the head of the stud 51 to pass so that the member 50 may be easily removed from the machine after the stud 53 has been unscrewed.

To assist the passage'of the lacing hooks along the raceways, a tapping device is provided in the form of a lever 65 pivoted at 66 to the frame 2 and moved by a cam 67 mounted on a shaft 68 which is driven by a belt 69 connecting pulleys 70 on said shaft and pulley 71 on main shaft 13 of the ma? chine. The spring 54, before referred to, maintains the roller on the lever 65 in contact with the cam 67 and said lever is pro- .vided with two adjustable strikers 73, Fig. 2, each of which strikes against one of the raceways 8.

As herein shown, the holder member 34 has two plates 75 pivotedto it at 76. When the holder member is removed from the machine these plates are held in parallelism therewith by a spring 77 and extend under the heads of the hooks seated in the recesses 35 to secure the hooks in position in said recesses. On the insertion of the holder member 34 in-the machine, the free ends of the plates 7 5 come in contact with guide'bars 78 secured to the frame 2 of the machine and .as said holder member is moved back to actuate the supplying means said plates are caused to open out as shown in Fig. 2, thereby uncovering the recesses 35 preparatory to the introduction in said recesses of hooks from the raceways. As the holder member 34 is now moved toward the front of the machine in removing the hooks from the lower end of the raceway, plates 75 will gradually approach each other under the action of the spring 77 as they are permitted by the action of guide bar 78 and by the time that,

the holder member 34 is fully loaded with hooks and in readiness to be removed from the machine the plates 75. will have come into engagement with all the hooks in the recesses and will hold them in position therein so that the holder member can be removed from the machine without danger of the hooks being displaced.
