GOLF SHOE CALK WRENCH Filed Sept. 27, 1967 LEO CHMIELEWSKI gm, w gu ATTORNEY United States Patent 3,412,635 GOLF SHOE CALK WRENCH Leo Chmielewski, Miami, Fla. (67 NW. Palmetto Expressway, Hialeah, Fla. 33012) Substituted for abandoned application Ser. No. 239,667, Nov. 23, 1962. This application Sept. 27, 1967, Ser. No. 677,824

1 Claim. (Cl. 8190) ABSTRACT OF THE DISCLOSURE The calk wrench includes a stem having an integral cylindrical enlarged head at one end thereof and a threaded portion between the head and the shank of the stem. The other end of the stem is a non-round extension for engaging a handle. The bottom of the head is upwardly and inwardly recessed to form a conical surface serving as a guide, and the marginal edge of the conical surface is a concave face which conforms to an oval face of the calk so that the head seats on the calk. The top of the head is flat, and a pair of diametrically arranged apertures extend from the flat surface through the head and the concave surface. Pins extend through the apertures and project below the head, and the pins have flat head which engage the flat top of the stems head. A clamping nut is screwed on the threaded stem portion into engagement with the pins to retain them, and the nut can be unscrewed to slide freely along the stem, thereby allowing replacement of the pins. A handle includes a ratchet having a non-round recess receiving the non-round extension of the stem and a pawl having a lever recessed into the handle for setting the direction of ratcheting. Another recess is provided for holding spare pins.

This application is a substitute for application Ser. No. 239,667, filed Nov. 23, 1962, by the same inventor and now abandoned.

This invention relates generally to a spanner wrench primarily for use in removing or replacing the conventional calks employed in golf shoes or the like, such calks embodying a screw that engages into the sole of the shoe and with the screw carrying a relatively wide flange to limit the movement of the screw into the sole and with the flange having an oval face that is axially provided with a prong and at least two diametricall opposite recesses for engagement by the tool and whereby to turn the calk when it is to be removed or replaced.

The present invention comprises a spanner wrench that carries a pair of replaceable pins for engagement into the recesses of the calk flange and with the wrench having a stem portion that has a relatively close engagement into a socket of a ratchet wrench and with the ratchet wrench having a socket mechanism so constructed that the operator may rotate the calk wrench by back and forth movement without requiring that the ratchet wrench be rotated throughout an arc of 360 degrees, such action greatly facilitating the use of the spanner.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

FIGURE 1 is a side elevation, partly in section, showing a calk wrench constructed in accordance with the invention.

FIGURE 2 is a top plan view thereof,

3,412,635 Patented Nov. 26, 1968 FIGURE 3 is a bottom plan view thereof, parts being broken away for purpose of illustration,

FIGURE 4 is a view at right angles to FIGURE 1 and with the ratchet handle being removed, and

FIGURE 5 is an enlarged section through the spanner wrench, taken on line 55 of FIGURE 4.

Referring specifically to the drawings there has been illustrated a cyindrical stem 5 that is provided with an enlarged cylindrical head 6. The head 6 is axially conically recessed as shown at 7 and the recess terminates inan outwardly flared circumferential concave face 8. The face 8 is adapted to substantially conform to the curvature of the oval flange of the well known calks, while the conical recess 7 receives the prong or pin projecting from the calk when the wrench is applied thereto. The head 6 has an annular flat top 9 and with the head 6 being provided with cylindrical apertures 10 that extend entirely through the head at diametrically opposite points upon the head and the apertures 10 extend from the flat face'9 through the beveled face 8. The apertures are adapted to receive cylindrical pins 11, having flat enlarged heads 12 that engage the top flat face 9 of the head. The pins, as clearly shown, project below the head 6 a distance capable of engaging the apertures of the calk. The conical shape of the recess 7 serves to guide the head 6 over the prong of the calk, and thus helps to center the wrench relative to the calk so that the pins 11 can be easily aligned with the apertures of the calk.

Means are provided to hold the pins in the apertures 10 for operative use and against displacement, comprising a nut 13, having a knurled circumferential face 14. The nut is threaded upon a threaded enlargement 15 of the stem 5 and whereby the nut may be unscrewed from the enlargement 15 to freely slide upon the stem 5 when the pins 11 are to be replaced. Since the threads at 15 are larger in diameter than the stem 5, nut 13 will slide freely on stem 5 when the nut is unscrewed. The stem 5 at its upper end is provided with a reduced non-round extension 16, for a purpose to be pres ntly described. The portion of stem 5 between extension 16 and enlargement 15 comprises a cylindrical shank.

Means are provided to rotate the head 6 and the pins 11 for removing or replacing worn calks that comprise a ratchet handle, indicated as a whole by the numeral 17. The handle 17 has a cylindrical hub 18 and a pair of slightly tapered round arms 19 and 19'. The handle 17 includes a ratchet 20, having a non-round socket 21, dimensioned to receive the extension 16 of the stem 5. The ratchet 20 is actuated by a double ended pawl 22, shiftable by a latch arm 23, that is fixed to the pawl 22 and with the latch being disposed within a recess 24 of the hub 18 whereby the latch will be disposed below the upper surface of the hub to avoid contact with the hand of the operator. The ratchet 20, double ended pawl 22 and a biasing spring (not shown) may be constructed as described and shown in US. Patent No. 1,970,409 to provide a double ratcheting action. Latch arm 23 is shiftable to change the end of pawl 22 which is in engagement with ratchet 20 to thereby change the direction of ratcheting. The arm 19' is recessed axially as at 25 for receiving spare pins 11. The recess 25 is normally closed by a threaded screw 26, that has threaded engagement into the recess 25 and the screw 26 is provided with a knurled head 27.

In the use ofthe device, the stem -5 is engaged with the handle 17 :by inserting the non-round extension 16 into the socket 21 of the ratchet. The ratchet socket may or may not be provided with a detent for snapping engagernent into a socket that may be formed upon the extension 16. With the parts assembled and with the pins 11 firmly held into the head 6 by the nut 13, the latch 23 may be shifted laterally to engage either end of the pawl 22, depending upon the desired rotation of the tool for either the removal or replacing of the calks, and with the pins 11 engaged into the recesses of the calks, it only requires that the operator move the handle 17 back and forth a number of times to cause the calk to be disengaged from the sole of the shoe or to be firmly screwed into place when the latch is moved to the opposite position.

It will be apparent from the foregoing that there has been provided a very novel type of calk wrench that permits the operator to firmly hold the pins 11 into engagement with the calk throughout the movement of the device. In other calk wrenches, it is difiicult to hold calk pins or spanner wrenches into the calk since the pressure upon the wrench would be varied during the rotation of the device. In this particular invention, the operator can firmly hold the wrench in engagement with the calk at all times without danger of the pins slipping from the recesses of the calk. The device is formed of suitable metal having a high degree of resistance to corrosion and the pins 11 when worn at their free ends can be easily replaced. The device is strong, durable, cheap to manufacture and provides a very desirable and novel form of wrench for the removal or replacement of calks.

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the subjoined claim.

I claim:
