INV ENT OR.

ATTORNEYS United States Patent O llhll SEM-AUTMATC c'LlDEn MUNT FSR M'oses Perlman, dill@ ltd-th Ave., Brooklyn, NJ?. Filed Feb. 14, 196i, Ser. No. lidl 1 Claim. (Cl. 22h-2) The present invention relates to'improvements in the art of assembling slide fastener parts so as to make zippers or slide fasteners, and more specifica-lli the invention relates to Ia new and improved device for the mounting of the sliding and coupling members, which usually are called sliders on the rows of linterdigitating elements of a slide fastener, so `as to complete slide fasteners or zipper units.

The attaching of sliders to zipper units, when done by hand requires a certain `amount of skill in order to complete any apprecaible quantity of zippers during a certain period of time; however, even skilled operators are not able to `attach manually more than six thousand sliders to six thousand zipper units per day. The best mechanical devices hitherto developed have used a mechanism, actuated by solenoids and micro switches. Such a mechanism is too expensive and too complicated for being used widely in the highly competitive business of making slide fasteners.

Therefore, one object or" the present invention is the provision of a device of the charac er described which simplifies and facilitates the mounting of sliders on zippers to such an extent :that an unskilled worker can attach in a perfect marmer t* Telve thousand to thirteen thousand sliders to zippers during an ordinary eight-hour day.

Another object of the present invention is the provision of a device of the character described which is simple and inexpensive in construction since it consists of only a few parts that can be manufactured and assembled by mass production processes, and which does not require any electrical parts such as solenoids or micro switches or the like.

A further object of the present invention is the provision of a device of the character described which is comparatively small in size, and light in weight, so that it can be installed easily or mounted on a table or ti e like -at locations which are most convenient in relation to other pieces of machinery used during the zipper making process.

With the foregoing and other objects which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed Out in the claim, it being understood that changes may be made 4in the construction and arrangements of parts of the embodiment disclosed without departing from the spirit of the invention as claimed.

In the accompanying drawing l have set forth an illustrative embodiment of my invention.

in said drawing:

FIGURE 1 is a top plan view of a preferred embodiment of my invention with a fraction of its top cover shown open so as `to present a fractional top view of the inner mechanism;

FIG. 2 is a side elevation;

PHG. 3 is a detailed side elevation of the interior mechanical elements of a modification; and,

FlG. 4 is ia fractional top view of the modified elements of FlG. 3.

Similar reference characters refer to similar parts throughout the several views.

In the drawing the numeral 1 denotes a casing having a top portion 2, and wall portions 3, as well as a llhfil base portion 4 (FIG. 2). Attached to a wall portion 3 f the casing l1 is a channel member :'s which has a tf-shaped end portion 7 and a longitudinal channel l@ as well as a traverse channel il. that crosses the channel it?, as may be seen in FIG. l. The member 5 also has a recessed portion l2 of a substantially inverted U-shaped formation, and in which are rotatably arranged a pair of disks l5, which have bevelled, reduced end portions and are mounted on a shaft that is rotatably mounted in bearings 2l?. The bearings 2l) are mounted on the casing l, through a portion of which the shaft 17 is traverse-ly extended. A pair of ring `members 21 `and Z2 are irmly secured to the `shaft i7, and a friction disk Z3 is secured to `the member 21. A sprocket wheel 2e is rotatably `and shiftably mounted on the shaft 17, and is connected by means of a sprocket chain Z5 to a small sprocket pinion 27, that is secured to a shaft 30 of `a reduction gear 3l, which is in driving engagement with an electric motor 32 mounted within the casing l.

A counter friction disk 33 or any other suitable surface preferably is secured to the wheel 24, and is in engagement with the friction disk 23, and `a pressure spring 34E- is interposed between the member Z2, and the wheel Zei', so that the member 2l and the shaft 17 will be taken along and caused to rotate if the wheel 242- is being rotated, provided there is no considerable force exerting a braking action on shaft 17, in which case a slipping of the elements 23 and 33 on each other will be caused, allowing a rotation of the wheel 2d without tacking along the

parts

23, 2l, 17 and l5.

One, or two, or more cross pins 35 are traversely extended from one or" the disks 15 to the other and are Secured thereto, A knob 37 is secured to that portion of the shaft i7 which `extends through the channel member 5 and beyond the sane.

A slide arrester do, which may be of any suitable shape and construction, is mounted on the top wall portion 2 of .the casing l. in the instance shown the arrester il@ consists of -a base l carrying a bi-urcated upright member 4Z, to which is pivot-ally attached at 43, a curved lever A downwardly extendinfr oblique end portion d5 of the lever 44 is forced by ya spring 49 to extend into the way `of a row of sliders e7, which are being slid down by means of gravity, from a slider handling device `(not shown), on a guide rail Si: toward the intersection of the channcls lll and .ll or" 'the inember i6.

lf the members l5 and d'7 `are rotating in a counterclockwise direction, any slider 47, extending into the channel l@ and arrested in its sliding movement by the arrester dil, will be engaged by `one of the pins 35 and will be moved away from the arrester 4i?, toward the end of the channel iti; there the thus engaged slider i7 will be stopped, and with it will also be stopped any further rotation of the parts l5 and 17, while the elements Z3 `and 33 are in frictional relationship to one another. The said stopped slider is now in a convenient position for being inserted by an operator in between the rows of interdigitating elements of a slide fastener or zipper unit. Thereby the said slider is removed from the device, so that the `aforerrientioned braking action ceases, and another slider is bein-g pushed into the place of the aforementioned slider 57 by the action of the elements 35, l5 and l'l' in the above described manner.

According to the modification of FIGS. 3 and A., the elements l5, i7, il and 24 are replaced by a pair of wheels Sl mounted on a shaft 53, and connected by a pair of chains Srl, or a belt or the iike,vto another pair of wheels S5, which are rotatable on a 4shaft 57. Here, the wheels 5l are firmly secured tothe shaft S3, as are the disks lo' in the embodiment of FEGS. l and 2, and

the chains or the like 54 are connected to each other by traverse pins e@ which are adapted for eng-aging sliders in the same mmrner as the pins 3S of FlG'S. 1 and 2. Rotatably and shiftably to the strait 53 is attached la wheel 6l, which is driven by a belt 52 or the like, that passes round `a pulley 63 of a reduction gear 6d, driven by a motor 66. The wheel di also is provided with a friction surface 67, that is in frictioi a engagement with a friction disk 7i? attached to a ring member '7l which is rmly secured -to the shaft 53.

Since certain changes may be made in the above article and diierent embodiments ot the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood Ithat the following claim is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

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