I t 7 Application filed FehryiaryZL-IQOB. Serialllo.;144,4=l8. (No model.) I V sidingat New Britain, in the county of Hart: ford and. State, of Connecticut, have invented a newfa'nd useful lce-Greepergof'which the designed to be attached; to =a-boot or shoe to This invention relates tothat class of devices prevent slipping onice or hardened snow. It is the object to provide a structurewhich may be readily-manufactured, can besecurely Figure .1 is a side elevatiomofgone of thev structures, indicating the manner-ii'n which it is applied to a shoe.

Inthe structure illustratedin thefirst five figures of the drawings, a base-plate 10 is employed having downturned flanges 11 at its parts inall the figures of the drawends, the edges of said flanges being serrated" to form rows of teeth 12. This base-plate is preferablyformed of sheet metal and conforms to the shape of the shank of the sole, being adapted to fit against the same and just in advance of the heel, as indicated in Fig. 1. As there shown, one of the flanges abuts against the heel and is somewhat longer than the one located at the front end of the plate.

A pair of spaced clamp members 18 are slidably mounted upon the base and comprise metal strips that extend across the under face thereof and having upturned sole-engaging hooks 1 1 at their ends, said hooks extending around and above the side edges of the base- Be it known that I, CHRISTiAN F'nrn nnicn ,RECKNAGEL, a citizen of the United States, re-

plate The, clamp members are secured; to the base by means of screws 15 or other fasf tening devices, which'pass through transverse slots 16, formed in the members. Journaled :between these members is an actuating and locking device therefor in .tlieform ofa cam.

comprising a plate 17 secured to the base by a suitable. pivot.18 and having cam-slots 19 arranged 'on opposite sides of the-pivot; This plate is provided with a handle-lever 17*, by means of which it may b'eactuated. Project: ing lugsQO, arranged. upon the clamp mem: bers, engage in the slots 19 and bear against the edgesthereofl. An additional lockinthe formof a block 21 is preferably secured to theinner-face of the cam-plate and is ellip-; tfi'cal: in form, being located between the clamp members andarrangedto bear against their opposing inner edges, as clearly shown in Figssd and 1. 1 Y i In applying the'deviceto a boot or ,shoe the lever is first swung outwardly, whereupon the clamp members will be drawn-towardeach other.

The creeper is then arranged against the shank of .=the-sole.,and ,the lever, ;-moved back toen-position. against or contiguous to -the heel-. i'l-"Th-iswillmove. the clamp members away fromeach-ot her and the hooks-thereof will engage thesole-shank'. The block 21 will 1 thus be dis'posed in the position; illustrated in I Fig." 2 and :"serve as additional locking ,means,,

which will prevent the clamps movingtoward each other and turning the cam-plate.

T In Fig.6 a slightly-modified form ofconstruction is illustrated; The elements are substantially the same as those above described, with the exception of the clamping members. In this instance said members are arranged longitudinally of the base-plate and are designated by the reference-numeral 13 The terminal hooks 14 of each clamp member'extend from the same side of the creeper, and the cam-grooves 19 are so located thatfwhen the camis rotated the clamping members will be moved toward each other, or, in other words, transversely ofthe base-plate. The

action is, however, substantially the same and is as efiective as the arrangement first described.

It will be evident that this structure may be manufactured at small cost, as the parts can be formed of sheet metal stamped to proper form. The creeper, furthermore, when secured will not slip upon the shoe or boot and will not only prevent slipping upon ice, but will constitute a support for the instep of the wearer.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

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

1. In an ice-creeper, the combinationwith abase, having spaced sets of depending spurs, of shoe-engaging members movably mounted on one side of the base between the sets of spurs and having terminal hooks that project above the opposite side edges of the base and engage the shank of the shoe or boot, and means coaoting with the members for moving the same toward and from-eachother.

2. In an ice-creeper, the combination with a base having downturned flanges at certain of its side edges, of shoe-engaging members movably mounted on the base and having upstanding sole-engaging hooks projecting above the other side edges, and a cam journaled on the base and coacting with the members to move the hooks into engagement with the sole of a shoe and thereby secure the base with the flanges transversely of said shoel 3. In an ice-creeper, the combination with a base-plate having downturned flanges at certain of its opposite side edges, said flanges being serrated to form spurs, of shoe-engaging members slidably mounted on the under side of the base between the flanges-and having upstanding sole-engaging books that extend across the other opposite side edges of the base and project above the same, a camjournaled upon the under side of the base between the shoe-engaging members and extending beneath the under faces of said members, movable connections between the cam and members, and a handle carried by the cam and projecting from one side of the base, said handle swinging between the corresponding ends of the flanges.

4. In an ice-creeper, the combination with a base having rows of depending spurs at its ends, of clamp members slidably mounted on the under side of the base and extending across the same, said members having outstanding sole-engaging hooks projecting over the side edges of the base, and a cam journaled on the under side of the base between the members and coacting with the inner opposing edges thereof.

5. In an ice-creeper, the combination with a base having spurs, of spaced clamped members movably mounted upon the base, and a revoluble locking device located between and bearing against the opposing inner edges of the clamp members.

6. In an ice-creeper, a base-plate arranged to fit against the shank of the shoe-sole, said plate having its end edges downturned to constitute terminal flanges and serrated to provide transversely-disposed rows of teeth, one of said flanges being of greater width than the other and arranged'to abut against the heel of the shoe, and means for securing the plate to the shoe. I

7. In an ice-creeper, the combination with a base having downturned flanges and edges located in angular relation to the downturned flanges, shoe-engaging members having upturned hooks projecting above the said angularly-disposed flanges, said hooks .being arranged to engage a boot or shoe and maintain the flanges in transverse relation thereto, and means for moving the shoe-engaging members.

In testimony that I claim the foregoing as my own I have hereto aifixed my signature in the presence of two witnesses. I
