BENJAMIN GILOWITZ, OF GREENPORT, NEW YORK.

ATTACHMENT FOR SHOES.

Specification of Letters Patent.

Patented July 4, 1911.

I Application filed March 16, 1911. Serial No. 614,855.

To all whom it may concern:

Be it known that I, BENJAMIN GILowITz, a resident of the United States, residing at Greenport, in the county of Sufiolk and State of New York, have invented certain new and useful Improvements in Attachments for Shoes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in anti-slipping attachments for shoes.

()ne object of the invention is to provide an attachment of this character by means of which an ordinary shoe may be quickly converted into a base ball or running shoe thus obviating the necessity of providing separate shoes for this purpose.

Another object is to provide an antislipping attachment for shoes which may be connected to the sole and fastened in operative and inoperative positions.

l Vith these and other objects in view the invention consists of certain novel features of construction, combination and arrange ment of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a plan view of the lower side of a shoe sole showing the application of the invention and illustrating it in operative position; Fig. 2 is a similar view showing the attachment in inoperative position; Fig. 3 is a central vertical longitudinal section of the shoe and attachment with the parts in operative position as shown in Fig. 1; Fig. 4 is a similar view with the attachment in an inoperative position as shown in Fig. 2; Fig. 5 is an enlarged detail sectional view on the line 55 of Fig. 2; Fig. 6 is a detail perspective view of the attachment; Fig. 7 is a similar view of the catch for holding the attachment in operative position.

My improved anti-slipping attachment comprises a plate 1 which may be formed of any suitable metal and which is curved longitudinally to correspond with the curvature of the sole of the shoe. To the plate 1 is secured a series of pointed ground engaging studs 2 which project a suitable distance be low the plate when the latter is in an operative position. On the inner end of the plate is arranged an eye 3 which forms one member of a hlnge connection whereby the i-nects the plate to the sole comprises a small plate 4 which is counter-sunk or set into a recess 5 formed in the shoe sole at the end of the arch portion of the sole as shown. The outer end of the plate 1 is reduced to form a tongue 6 having on its outer end a right angular locking lug 7 in which is formed a locking notch 8 adapted to receive catch devices hereinafter described for holding the plate in operative and inoperative positions.

In the outer or toe portion of the sole is formed a recess 9 and a slot 10 which communicates with said recess and is adapted to receive the lug 7 when the plate 1 is swung to an operative position. Pivotally 1nounted in the outer portion of the sole is a catch 11, said catch comprising a locking plate 12 arranged in the recess 9 and having formed on one end an outwardly projecting shank 13 on the outer end of which is secured a catch operating plate 14. Secured to the outer side of the plate 14 is a spring detent 15 the outer end of which is bent inwardly and is adapted to work in a notch 16 in the plate 14 and to be engaged with a locking recess 17 in the sole to hold the locking plate 12 in an operative position and with the slot 10 to hold the catch in an inoperative position. In the sole of the shoe between the recess 17 and adjacent end of the slot 10 is arranged a counter-sunk wear plate 18 with which the end of the detent 15 is engaged when the catch is swung to operative and inoperative positions whereby the detent is prevented from wearing the sole of the shoe.

When the plate 1 is swung to an operative position as shown in Figs. 1 and 3 of the drawings, the lug 7 will enter the slot 10 and when in this position the catch will be turned by the operating plate 14 to engage the locking plate 12 with the notch 8 in the lug of the plate 1 thus fastening the attachment in operative position. When the catch has thus been turned to lock the attachment the detent 15 will spring into engagement with the recess 17 thereby holding the catch 'in locked position thus preventing any possibility of the catch becoming casually opened and thus releasing the attachment.

WVhen the attachment is to be swung rearwardly to an inoperative position the detent the plate 1 whereupon the latter may be swung back against the arch portion of the sole as shown in Figs. 2 and 4 of the draw ing. When the plate 1 is thus swung back the tapered end or tongue 6 of the plate will be engaged with a similarly shaped notch 19 formed in the heel. When thus swung into engagement with the arch portion of the sole the pointed studs on the plate 1 will engage tapered recesses 20 formed in the arch and heel portions of the sole.

In order to fasten the plate 1 in a retracted or inoperative position I provide a locking bolt 21 which is slidably mounted in a longitudinal passage 22 formed in the heel. On the inner end of the bolt 21 is arranged an enlargement 23 which forms a stop for one end of a coiled bolt projecting spring 24 which is arranged on the bolt 21 and has its opposite end engaging the inner end of the recess 22. On the enlargement 23 is formed a locking lug 25 which is adapted to engage the notch 8 in the lug 7 of the plate 1 thereby holding said plate in a retracted position. On the outer end of the bolt 21 is arranged a suitable head or knob 26 whereby the bolt may be retracted against the pressure of the spring 24 to disengage the lug 25 from the notch 8 in the plate 1 thus releasing the latter and permitting the same to be swung around to an operative position in which position the same is locked by the catch hereinbefore described.

When the plate 1 is swung back to an inoperative position the operating plate lt of the catch mechanism is designed to cover the and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.

Having thus described my invention what I claim is:

1. An anti-slipping attachment for shoes, comprising a plate provided with anti-slipping devices, means to hingedly connect said plate to the sole of the shoe, a locking lug on the free end of said plate having a notch therein, a latch pivotally mounted in the sole of the shoe adjacent to the toe end thereof and having means for engagement with the notch in said lug.

2. An anti-slipping attachment for shoes comprising a plate having thereon anti-slipping devices, means to hingedly connect said plate to the sole of a shoe whereby the plate may be swung to operative and inoperative positions, a locking lug formed on the free end of said plate, said lug having therein a locking notch, a catch pivotally secured in the sole of the shoe adjacent to the toe end thereof, said catch comprising a locking plate, an operating plate secured to said locking plate whereby the latter is swung into and out of engagement with the notch in said locking lug, a detent arranged on said operating plate and adapted to hold the catch in operative and inoperative positions, and means to hold the attachment in an inoperative position.

3. An anti-slipping attachment for shoes comprising a plate having thereon anti-sliping lug carried by said bolt and adapted to be projected thereby into engagement with the notched locking lug of the plate when the latter is in an inoperative position, and means whereby said bolt may be retracted to V disengage the locking lug from the plate. mechanism in the front end of the sole as 4:.
