1s claims.

This invention relates to mechanism for automaticallyfeeding hook fasteners and similar ar-` ticles subject to various operations,` such as attaching the same by sewing, stapling, riveting or;

'other fastening operationato garments or garment parts, hook and eye tape bodies, display cards, etc.

VThis invention has for its principal object ,to

`provide a simple and effective*automatic` hook I0 feeding and delivery mechanism, whereby hook fasteners deposited in a holder or magazine are `successively ejected therefrom and delivered in readiness forvarious operations to which it is desired to subject the same. f ,v

`Other objects of this invention, not at this timer moreparticularly enumerated, will be Vclearly Vun-` derstood from the following detailed description. ofthe same. Y

Illustrative embodiments of this invention are shown in the accompanying drawings, in which:--

r Similar characters of reference are employed in the above described views, to indicate corresponding parts. Y l

Referring to the drawings, the reference charv acter 15 indicates the base on which the novel hook feeding and delivery mechanism is mounted. vSuitably xed on said base 15, as by screws 16 or any other desired' fastening means, is guide block 17. Said guide block 17 is provided with a forward extension 18 preferably of reducedA height.

Formed in the extension 18, at4 the juncture there.-

Formed in the forward end portion of said vcarrier member 21 is a' hook receiving pocket 23, whichextends vertically'Y frorntop to i bottom. of said carrier member. Said'rhookreceiving pocket 23 is of a lengthtransverselyjof the carrier member, slightly'exceeding the-widtliif dled by the mechanism; and is of'fa width,', 1ongi `-"4 tudin'ally ofthe carrier member,lslightlytexcced-l ing the thickness offsaid baseipqrtion a of,said

'Fixed on said guide I'block 'ITtoriseJupwardlyfl therefrom, and sothat. its lower end bridges 'acrossr the carrier'member 21,is` a, magazine .25',` havingja vertical channel 26fto receive the bas'portionsd of hook devices deposited there'injand a channel 3 27 of reducedwidth adjoining the same torec'eive` l; the bill portions bof said hooi: devices. 'A covei` 85 or back plate 28 is secured to the` channeled'face'of said magazine 25 to close therear side offthehook M passage `prnvided by said channels 26 fand 2'l.`y The hookdevices are deposited `within the hook passagev thus provided bythe magazinesoaslto form a vertical column thereof arranged endto end, preferably overlapping as'shown in the drawings, and subject to `gravitation toward the bot-bA tom of the magazine andthe carrier member`21l" rier` member 2l, and to'iassure the prope'rfalign-v Yment of thev receiving pcket zs'thereof with the hook passage of the'magazinefvvhen `the carrier member"V is retracted,fit is `preferable to provide shoulders 29 and 30 inconnection with the` carrier member." Removably affixedto the magazine isa stop member 3l, whichfis jengageable by the..V

Should it be desiredk vto removebrdisassemble 'the carrier member at any time, the stop member '31 may beloosenedand withdrawn from the path of movement thereof, whereupon the vcarrier member may be withdrawny from the slideway'of the guide block.

vhook devices. Extendingforwardly"fromsaid.

l While I have shown and ldescribed the carrier member as capable of reciprocable movement, thisv wardly beneath and across the drop well 19 and.

` through the underside'of the extension 18, to the l outer extremity of the latter. vAny suitable means may be provided for imparting properly timed movement to said push-plate 33 through the actuating lever 34 which engages the rear endy thereof.

Said push-plate 33 is provided at its forward end with shoulders 35Vto engage the base portion a of a hook device deposited in front thereof, and rearwardly of said shoulders the push-plate is indented by a clearance notch 36torec'eive the bill portiony b of' the. deposited hook device. At

one side, Yatv least', the push-plate 33 is provided with av forwardly projecting finger 37 having a chamfered free end which extends beyond the for-` ward limits of the base portion d of Aa hook device v 3()l operatively engaged Vby the push-plate. This finger 37 maybeomitted, but is desirable when the hook feeding and delivering mechanism is used to insert the hook devices beneath a iiap of a garment, holding .tape body or the like, forv sihiilar purposes. In such cases, the finger 37 enters beneath the ap in advance `of the hook device and raises the same sufficiently' to' assure the free unobstructed passageor movement of the hook 'device beneath such iiap. f

Formed inthevertical wall of .the guide block 17- which bounds the rear side of the drop-well 19 isa vertical groove Vor'cliannel 38 to provide Vclearance for the hook bill b when a hook device is initially manipulated by the push-plate 33 in the 45,;manner subsequently explained. In like manner formed in theunder side of the extension 18 above the push-plateslideway is a longitudinal groove or channel 39 of dimensions .calculated to provide clearance or passage for the hook bill b of a hook y y 5Q3gdevice propelled `outwardly vby ther` push-plate.

18 which borders the forward side of the drop- Well 19y is an indented notch or slot 40 to pass the bill ,portion b of a hook device enteredY in said 55,;3drcp-well, and the under-marginal portion of Formed vin the inner end portion of the extension said extension bordering said drop-well'is down#Y wardly and inwardly curved atthe juncture of said drop-well withrthe push-plate slideway, as indicated at 4l, thus permitting clearance for the 691 base portion a of a hook device, as the same is turned'from vertical standing position within said drop-well `to 'a horizontal position within said push-plate slideway.

It is desirable to provide means to overlap gar..

jment or tape material, or cards orother material to and upon which the hookA devices are to bedelivered, so as to assure smooth unobstructed movement of the latter upon the former. To this `end IA provide intermediate the base 15 and eX-` ytension 18 a resilient yieldable tongue 42 which normally lies withinrthe end ofthe push-plate slideway 32, and in the path of a hook device advanced by the push-plate'33. The material upon h which thehook devices are to be delivered may be 5 `moved beneath said vtongue 42 so as to beY overlatter will at once dropdown into said receiv- Vhook lfeedingfand delivering mechanism, which lapped by the latter. yWhen a hook device is ad-` vanced by the push-fplate said tongue 42 willyield to the passage thereof but, since the tongue overv lies thematerial, the hook device will be guided over the edge of the material by the tongue, and will consequently ride smoothly and surely off of the tongue and on to the material. The tongue may be mounted in the described operative relation in many different ways. A convenient method of mounting the same however consists in forming .the tongue 12 in connection with a shim plate 43 interposed and secured between the base 15Vand guide block 17, as shown in the drawings.

In the operation ofthe form of hook feeding and delivering mechanism above described, when the carrier member 21r is retracted, its hook receivingpocket 23 is brought into alignment with the lower end of the magazine 25, whereby the lowermost hook contained in the ing pocket (see Fig.` 3). After a .hook device is thus ydeposited in the receiving pocketof said carrier member, Vthe latter vis advanced, whereby the body of the carrier merriber closes' the. bottom of the magazine against hook discharge .and whereby the receiving pocket is Ymoved 'forward'. ly into alignment with the drop-well 19,` so that the yhook device may drop out of thefreceiving pocket and into.',theffdrop-well 19, `in front ofv the push-plateV 33, .so that the hook .device is deposited with fthe lower end ofv itsbasejpor-v tion a lodged` within the push plate slideway 32 in advance of the shouldersfS Withwhich the forward end ofisaid'push-plate is provided (see Fig. 5). After 'the hook device; is. thus disposed, forward movement is imparted tothe push-plate, whereby the shoulders 35 engage l the ldownward edge of the hook base' a so. as

- to push the same forward, thuscausing` the'hook' .device to be turned into down'flying position a` in front of the shoulders 35 (see Fig. 7),. 120 When the hook device is thusV disposed,'a iinal forward movement vis imparted to the push-,` plate 33, wherebythe clearance notchreceives the hook Ybill portionv b, and the shoulders 35@ engage ythe hook base portion c, so as to' propel 125 therhook forwardly and outwardly throughtheV slideway. (see Figs. 8 and 9).l As the hook device is thus propelled outwardly, the same is caused to ride over they tongue 42 and thence on to the'material to which the same is to be delivered. If the material happens'to be `a tape body t having a flap t `or the like beneath which' it isdesired to insert thehockbase a, then lthe outwardly moving pushplate will carry the finger 37 beneath the flap t in advance of the ap- 135 proaching hook, so as to lift said flap fory ready and unobstructed admission of the hookbase a i thereunder (also see Figs'. 8 and A9). u

While the'push-plate 33 is advancing to perform its functions, the carrier member 21 may be retracted in position to receive within its receivingpocket. 23 the next hook device to be delivered by the mechanism, and by properly timed relative reciprocations of said carrier member`and push-plate, the above operations may be successively repeatedas desired. y

Referringnow to Figs. 10 and l1, I have shown Y therein a `modified arrangement of the novel isisubstantially ,the same Vas already. above de-l'0 iisA 1 tion of corresponding` scribedexceptfthat the carrier jmemberlis dien posed fortransverse rreciprocation relativey to the `magazine 25 and block. 17 Yinstead, of for longitudinal reciprocation. In these views ythe modiiied carrier member is indicated bythe referencecharacter 2l', vandfthe same is provided, with a receiving pocket-23 `having a horizontal cross scc'tionalshape corresponding to thatoi the channeled `hook passage offjthe magazine.,

In ,other respects the structure is the samer-,as abovedescribed, as is witnessed by the `applica .reference charactersI to the details thereof.` v
