WILLIAM S. 'IO'IHILL, OF CHICAGO, ILLINOIS.

'I-IIGH-J' UMP STANDARD.

Specification of Letters Patent.

Patented July 30, 1912'.

Application filed October 24, 1910. Serial No. 588,871.

To all whom itmay concern Be it known that I, WILLIAM S. To'rHILL, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in High-Jump Standards, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to high jump and vaulting standards and has for its object the provision of novel mean-s by which the barsupporting members can readily be adjusted to different heights, and by which, when the standards are used for pole-vaulting, the bar-supporting members may be easily and quickly lowered, the bar placed in position thereon, and the bar-supporting members readily raised to the desired height by attendants stationed on the ground at the bases of the standards.

This invention is especially designed to meet the requirements of use at public playgrounds, and it is one of the objects to provide a perfectly safe construction and one subject to as little abuse as possible.

With a certain prior construction of vaulting standard employing a sliding bar-support, the boys in the play-grounds have been used to placing two such standards side by side with the bar-supports near the ground. Then standing on the bar-support of one standard, one of the boys would, with his free foot, raise the bar-support of the other st'andard'to a point slightly higher than the one on which he was standing and after securing it in position would shift his weight to that bar-support and repeat the process with the other foot. In this manner he would work his way to the tops of a pair of ten or twelve foot standards.

It is one of the objects of this invention to provide a sliding bar-support the p0si- 7 tion of which can easily be changed by hand but which cannot readily be changed in the manner just described in connection with the old construction, thus doing away with the danger of injury through this abuse.

Another object of this invention is to improve standards of this type in sundry details hereinafter pointed out.

The means by which I have accomplished these objects are illustrated in the accompanying drawings and hereinafter specifically described.

That which I believe to be new will be set forth in the claims.

In the drawings,Figure 1 is a side elevation of a standard embodying my improvements. Fig. 2 is a front View of said standard. Fig. 3 is a cross section on line 33 of Fig. 1, somewhat enlarged. Fig. 1 is an enlarged detail, showing the engagement with the standard of the pivoted link member of the sliding bar-support. Fig. 5 is an enlarged detail, showing a modification of theconstruction shown in Fig. 4. Fig. 6 is a side elevation of the upper end of a standard especially designed for use in vaulting.

Referring to Figs. 1 to 1, inclusive, in which corresponding parts are indicated by like reference ch-aracters,-'1O indicates a base, rising from which is the upright bar v11, whichis to be of any suitable-length,-de-

pending upon the use for which the standard is designed,say substantially sevenfeet for the high jump and thirteen feet for the pole vault. 12 indicates a bar, in the construction shown in the form of a channel iron, secured to the bar 11 and spaced a short distance therefrom, being held in this position by means of rivets 13 and washers 141 which pass centrally through the web of the'channel 12. 15 indicates a slide comprising a piece of sheet metal 16 bent to embrace the bar 12 loosely and to slide freely thereon, and a bracket 17 having one arm extending horizontally. 18 indicates a link pivotally connected to the lower end of the bracket 17, the lower end of the link 18 being turned to extend toward the bar 12 and adapted to enter any one of the holes 19 in such bar. As shown in Fig. 4:, the end of the link 18 is notched on both its upper and lower faces for its engagement with the holes 19.

The operation of the device is readily understood. lVith two standards placed a suitable distance apart side by side, the links 18 are disengaged from the holes 19 and the slide is placed in position to support a crossbar of bamboo or other suitable material at the'desired height, the links being then engaged with the appropriate holes 19 to maintain the position of the bar-supports. If desired, either the bar 12 or the bar 11 may be marked OH to scale, to show at any time the height at which the support 16 stands, as is common in standards of this kind. With the link 18 pivoted to the slide and with the end of the link 18 notched as shown in Fig. 4, it is practically impossible for a boy to disengage the link with his foot and to mount the standards as described hereinbefore in connection with the old conto each numeral. In Fig. 5, the turned endof the link 18 is shown provided with a circumferential groove instead of being merely notched on the upper and lower faces. With this modified form of construction, it would be even more diflicult to disengage the link except by hand.

In Fig. 6, which shows another modification, the parts are numbered the same as in Figs. 1 to 4, except for the addition of the letter Z) to each numeral. In Fig. 6, which shows the upper part of a standard designed for use in vaulting, in which therefore the bar 11 is from ten to thirteen feet long, perhaps, the link 18 is from three to six feet long, say. lVhen' the crossbar is displaced by a vaulter, an attendant at each standard disengages the link 18 and lowers the slide 15. The crossbar is then placed in posit-ion upon the lowered slides 15 and by means of the long links 18 the supports are simultaneously raised to the desired height by the two attendants stationed on the ground besidethe standards, this operation being accomplished very quickly and being absolutely certain in its results.

What I claim as my invention and desire to secure by Letters Patent is,

1. In a standard of the class described, the combination with a base and a long upright 12* supported therefrom, of a horizontal support movable vertically along said upright, and a long link 18 pivotally con nected with said support, the free end of which link is adapted to engage any one of a series of openings in said upright to maintain said support in position.

2. In a standard of the class described, the combination with a base, an upright bar rising from said base, and a second upright bar secured to and spaced a short distance from said'first bar, of a slide loosely embracing said second bar, and a link pivotally connected to said slide, the lower turned end of which link extends toward said bar and is adapted to engage any one of a series of openings therein, said end being notched to prevent accidental disengagement of said link from said bar.

3. In a standard of the class described, the combination with a movable base, an upright bar rising from said base, and a channel iron secured to and spaceda short distanoe from said bar, of a slide loosely embracing said channel iron, a horizontally-extending bracket secured to said slide, and a link pivotally connected to said slide, the lower turned end of which link extends toward said channel iron and is adapted to engage any one of a series of openings therein.

4. In a standard of the, class described, the combination with a base, an upright bar rising from said base, and a second upright bar secured to and spaced a short distance from said first bar, of a split sleeve having a working fit upon said second upright bar, a horizontally-projecting bracket secured to said sleeve, and a link having a pivotal connection with said sleeve, the free end of which link is adapted to engage anyone of a series of openings in said second bar to maintain said support in position.

5. In. astandard of the class described, the combination with a base, and a channeliron supported in upright position from said base, of a slide loosely embracing said channel-iron, and a link pivotally connected to said slide, the lower turned'end of which link. extends toward said channel-iron and 1s adaptedto engage any one of a series of.

openings therein. J 1

6. In a standard of the class described, the combination with a base, an upright bar rising from said base, and a second upright bar secured to and spaced a short distance from said first-named bar, of a slide mounted on said second-named bar, and a. link having a pivotal connection with said slide,

the free end of which link is adapted to engage any one of a series of openings in said second-named bar to maintain said support in position.
