CLIMBING-SPUR.

SPECIFICATION forming part of Letters P Application filed December 1'7, 189

To @ZZ whom it may concern.-

Be it known that I, GEORGE M. HOWARD, a citizen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Climbing-Spurs, of which the following is a specification.

My invention relates to a new and useful improvement in climbing-spurs, and has for its object to provide a device of this descrip tion which will be simple in construction, cheap of manufacture, and which will offer special facilities for repair when the spur be comes worn or broken.

lVith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, its construction and operation will now be described in detail, referring to the accompanyingdrawings, forming a part of this specification, in which- Figure 1 is a perspective of a spur madein accordance with my improvement; Fig. 2, au edge view thereof, a portion being broken away to illustrate the method of attaching the spur-prong to the foot-bar', and Fig. 3, a detail perspective of said prong removed from the In carrying out this invention I provide a bar A, which is so shaped as to fit the instep of the shoe, the upper portion being adapted to lie against the lower portion of the leg and be secured thereto by a strap passing through the eye B, and the lower end of this bar is turned upward, as indicated at C, and is also provided with an eye D, through which a strap may pass for the securement of this portion of the device to the foot.

The principal feature of my improvement rests in the spur-prong E, which is of the shape illustrated in Fig. 3, and is made separate from the bar, but provided with a lug F, standing at an angle to the body of the prong and adapted to be inserted within an inclined hole formed in the bar, so that it may not be withdrawn therefrom upon a horizontal straight line, and this lug is prevented from withdrawal from the hole by a countersunk screw G being run in the threaded hole II, as clearly shown in Fig. 2. The prong is atent No. 596,113, dated December 28, 1897.

6. Serial No. 615,983. (No model.)

prevented from turning upon the bar by the elongation of the lug F in a vertical direction, and the hole in which this lug is tted is of a corresponding shape, and the screwI, which also passes through the bar and into the prong, by which arrangement but little or no strain is brought to bear upon the screws when the device is in use, since the strain inei dent to the supporting of a mans weight by the prong is transmitted to the bar through the lug F, and I have here shown au offset J, formed with the lug F, which, when taken in connection with the portion of the head of the screw G which comes in contact with the upper portion of the hole through which the lug passes, forms a perfect lug against the displacement of the prong.

In practice should the prong become worn or from other causes lose the desired shape it may be quickly repaired by removal from the bar and again replaced, thus obviating the necessity of handling the entire device for operating upon the prong, and when, as is Often the case, the prong becomes broken it may be replaced by substituting a new prong therefor, thus increasing the life and usefulness of the principal portion of the device indefinitely at very small expense, and when found desirable an extra set of prongs may be sold with each pair of climbers.

Having thus fully described my invention, what I claim as new and useful is- 1. A climber consisting of a bar adapted to be attached to the foot and leg of a person, a prong of suitable design for action upon the pole to be climbed, a lug formed with the prong arranged to fit within a hole formed in the bar, and a countersunk screw for securing said lug within the hole, as specified.

2. In combination with a bar of a climbingsp u r,a prong of the desired shape, alug formed therewith having a threaded hole therein for securing the prong to the bar, as specified.

3. In a climbing-spur, abar, api-ong, au inclined lug formed on the prong and fitting in a hole in the bar, substantially as described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribin g witnesses.

GEORGE M. HOWARD.
