ywhom t may concern.'

Be it known, that l, JAN SMoLARsKI a .citizen of Poland, residing at S. S. Umaha, .county or' Bouglas, and State of Nebraska, have invented certain new and useful .lmprovcinents in Shoe Keys and Buttons, of which the 'following is a speciiication.

This invention has as its object the provision of an implement to unite the two rts of snap fasteners as applied to shoes l like articles.

.mother object is to provide an implement wl cli may be readily maneuvered in such ier as to draw together the over-lapping portions or sides of the shoe, alining the elements of the snap fasteners and pressing them irmly into lockedengagement.

These objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part ofthis disclosure, and in which- Figure 1 is a perspective view showing a conventional type of shoe, and indicating the manner in which the implement is ap plied.

Fig. 2 is a top plan view of the implement shown in an extended position.

Fig. 3 is a side elevational view of the same, parts being broken away in order to disclose the interior.

Fig. 4 is a similar side elevational view showing the parts when in a closed position.

Figs. 5, 6, 7, and` 8 are perspective detail views showing the elements used in construction.

Fig. 9 is a side elevational View of the recessive fastening element.

Fig. 10 is a similar side elevational View of the incursive element.

Fig. 11 is a top plan view of the element shown in Fig. 10, and,

Fig. 12 is an enlarged bottom plan view of the spring chuck, engageable with the fastener element shown in Fig. 9.

Referring to the drawings in detail, particularly Figs. 9 to 11, the numeral 15 indicates the disk-like base of a recessive snap fastener, joined to the upper engaging portion 16 by a neck 17 which contains a spherical opening 18 below the convex head 19, adapted to receive a bulbous knob-like element 20, formed on a disk 21, connected by a stem 22, with a base 23, and formed in the side of the disk element 21, is a pair of recesses 24, the purpose of which will further on become evident.

The implement for engaging the fasteners includes a substantially flat spring 25, having a projection 26 at one side and form d at one of its ends is a downturned portion 27, terminating in an odset element beveled upon its lower side as shown in F ig. 5, and set in the upper side of the offset element 28, is a pair of pins 29 suited to engage in the recesses 24 in the manner which will be further on described.

A 0n the opposite end of the plate 25 is a pair of raised lugs 30 in which is hingedly engaged a curved clip or bail 31 and midway between the lugs 30 is a central lug or stop 32. j

Raised from the plate 25, upon its edges is another larger pair of lugs 33, having openings through which passes a spindle 34 the same acting as a fulcrum for a bent hand lever 35 having a curved upturned inner end 36, the opposite portion of the lever being held normally in a raised positiomdue to the effect of a coiled torsional spring 37. j

Secured upon the rear portion of the plate 25 is a hollow rectangular casing 38 containing at the front a recess 39, and slidably engageable within the casing 38 over the surface of the plate 25 is a rectangular bar 40 pressed normally forward by a coiled compression spring 41, within the casing 38 and abutting respectively against the end of the bar 40 and the fixed block 32. The front end of the bar 40 is guided laterally between a pair of projections 43, secured in the plate 25.

The lower front surface of the bar 40 is beveled, as at 44, and secured upon it is one of the elements of a hinge 45 by which is attached a, plate 46, having a. generally circular contour except at the rear which is raised, as L. t 47, and curved outwardly presenting a hook 48 engageable with the bent cnd 36 of the handle lever 35.

The plate 46 is normally held in a raised position due to the pull of a tension spring 49 connected between the curved portion of the plate and the bar 40.

Fixed to the lower side of the plate 46 is a rectangular block 50 having extensions 51 in which are pivoted upon the pins 52 four curved. jaws 53their extremities 54 being adapted to grasp, in the manner of a chuck, the curved heads 19, of the recessive fastener elements which are held, in position therein by springs 55j extending from the top of the jaws 53 to the lower surface of the plate 46, the effect being to turn the arms inward toward a common center, and cause them to tensionally grasp the curved surface of the fastener heads.

Fixed in the extension 26 is apost or stud 56 the same engagingin an open elongated slot 57 formed in a iev r 58 having` an opening 59 engageable with a pin 60, fixed in the bar 40 the'same acting as a'fulcrum for the lever 5S which y terminates in a rearward handle 61.

In operation, the jaws 54 having been applied to the top of the recessive fastener elements so as to grasp the same, the pins 29 are caused to engage with the recesses 24 of the incursive fastener element, whereupon the lever 61 is moved toward the i-er and obviously carries with it the plate together with the fastener, until the two portions of the fasteners are brought into registration at which time the hook elements 36 and 48 will be in register, so that upon depressing the lever 35 the two portions of the fastener are brought into forcible engagement, and maintained therein by the clip 31 over the end of the lever 35 until an engaging contact has been made between the elements, whereupon the clip 31 is swung outwardly and the lever 35 raised, releasing the jaw carrying plate 46 so that it rises from the fastener permitting the implement to be removed and engaged with another fastener if desired.

From the foregoing it will be seen that an easily operated and conveniently applied implement has been described whereby fasteners of the type-indicated may beengaged' without Contact of the fingers with the same. Having thus described my invention what I claim as new and desire to secure by Letters Patent, ism Y 1. In an implement for securing snap fas- `one of the elements ofthe snap fastener,

a slide movably mounted on said plate,

means for actuating said slide, a head car-l ried by said slide, a plurality of jaws carried by said head, said jaws being engageable with the other of said fastener elements, and means carried by said frame for depressing said head so as to cause engagement between said fastening elements.

2. In an implement for'connecting snap fasteners, the combination with a plate having an offset portion, projections on said oflset'portion engageable with one of the elements of the snap fasteners, a head slidably carried on said plate, pivotal jaws secured on the lower side of said head engageable with the Vother of said fastening elements,

means for actuating said head so as to cause one of the fastener elements to engage with the other fastener element, and means for causing contact between said fastening elements whereby they may be pressed together.

3. In an implement for securing snap fasteners, the combination with a plate, casing mounted thereon, a lever mounted to move transversely on said plate, a bar slidable in said casing actuated by said lever, a head hingedly engaged with said-bar, a plurality of jaws pivotally connected with said head adapted to engage with one of said fastening elements, said element being alinable with the other of said elements by actuating said lever, a second lever pivotcd transversely to the first named lever, means combined with said second lever engageable with said head whereby it may be moved upon said hinge, and means for normally maintaining said levers in operative position.

In testimonyy whereof I have afliXed my signature.

JAN sMoLa-Rsiri.
