Toallwhom it mag concern: I

Be it known that I, ANTHONY COUTURE, citizen of the United States, Chicopee, Massachusetts, have invented certain new and useful Improvements in Exercising Devices, (Vaulting-Bar,) of wh'ich 1 I the following isa specification.

i ,My invention relates to exercising apparatus of the vaulting bar or Swedish bar type, in which a boom is carried by uprights by adjustably. 7 1

One object of my invention is to provide means for holding the boom or bar to the uprights firmly, and without play or movement between theparts when in use, and my invention involves the use of a holding pin forsustaining the boom on the uprights, one of said pins being employed at each end thereof, and a friction clamplngshoe carried by a coupling at the end Of'the boom'to exert pressure upon the upright without marring the surface of the same in any way.

The inventionis shown in theaccompanying drawings, in whichi Figure 1 is a central vertical sectional view througha portion of one'of the uprights and one of the couplings to which "vention adapted to a horizontal bar type of exercising apparatus; Fig. 3 is a detail the boom is attached, my invention being carried by the said coupling Fig. 2 is a sec tional plan View ofanother form of my inview. Fig. 4 1s a sectional view onthe line X-X ofFig. 1. r

Referring to Fig. 1, 2. indicates oneof the hollow uprights which is provided with openingsone of which is shown at 3 to receive a spring pin 4, said pinibeing carried generally by the coupling shown ate i, said coupling having an extension at 5 to which the boom is secured in any suitable manner. The spring pin is mounted slidably in a sliding shoe 6 inthefo-rm of an; ellipse, which shoe is slidably mounted in the coupling between the guideways or portions 7. The shoe has pinned thereto at 8 aqscrew threaded extension or member 9 which is be noticed engaged by a nut 10 of sleeve form mounted rotatably in a cap piece 11 screw threaded into the coupling, the said nut having a handle 12 attached thereto by. a screwtoor from the upright 2. I It will residing at againstfthe surface of of the spring pin andriveted thereto, as in-.

device. 1 my invention adapted for horizontal bars in thatthe shoe on its interior face is curved on an arc conforming to the surface of the upright, andin assuming'position to clamp the coupling to the upright there is noslid ing orturning action of the clamping shoe the upright which would tend to damage the same, but this contact takes place by the direct movement of surface to surface, The spring pin .is pressed by a spring ltbearing at one end against the casing of the coupling, and at its other endupona shoulder 15 carried by 1 the pin, thisshoulder'being formed by a flange on a sleeve 16 carried by the shank dicatedat 17, so that, in effect, it is afixed part of the'pinstructure. In order to disengage the spring pin fromthe upright so that the coupling, together with tlie'boom or bar, may be adjusted vertically alongthe upright, the handle 12 is turnedto retract the elliptical shoe 6, and this presses back the spring pin by engaging with the shouler 15 thereof. When the spring pin is retracted from the opening, the coupling can be raised or lowered, the'shoe being free from the upright sufiiciently to permit this,

and when the approximate position has been reached the shoe may be advanced to the upright, and asfsoon as the pin registers with the opening in the upright it will spring forward into the same, the parts assuming the position shown in Fig. 1.'

A form of boom or bar may be used having different hand hold surfaces thereon,

and order to bring these difierentsurfaces into use the bar may be adjustedabout its 7 V axis, and for this purpose the-coupling is provided with the member 18 swiveled to the. main portion of the coupling by fitting thereon at 19 and being retained by the cap 11. This fswiveledmember 18 may have any suitable number of recesses 20 to be engaged by a spring pin 21, which will hold the swivel member in thedesired positions. The springpinmay be retracted by any suitable *In Fig. 2 I show another form of which the upright .2 is substantially the same .as'that first described," excepting that the first form of the invention, and the spring pin 4 in this instance is attached to the binding collar or elliptical shoeby' means by a spring a pin 24 passing through is applied to of a pin 22.

23 bearing thereon and on the wall of the coupling 4*. Diametrically opposite the pin and the spring arrangement I provide a device for operating the clamping shoe consisting of the hand wheel 12- 'to which is fixed a threaded rod 9 which engages the clamping shoe, the said screwthreaded rod 9 finding a bearing in the wall of the coupling, and the hand wheel also finding a bearing against this Wall. The threaded rod 9 is fixed to the hand wheel by upsetting or riveting its end over upon the hand wheel. The clamping shoe carries a slot 25 in the wall of the coupling, and this pin is adapted to be borne upon by a clamping button 26 pivotally mounted to the coupling and having an extended end 27 to engage the pin 24. In the operation of this device if it is desired to release the coupling from the upright the handle 12 is turned to run the screw rod back through the wall of the coupling a sufficient distance that when a direct thrust the hand wheel in the direction of its axis, the clamping shoe will be pressed bodily toward the right in Fig. 2 far enough to withdraw the pin 4: from the opening in the upright, this action being against the pressure of the spring 23, and it being understood that the rod 9 is not threaded into the coupling but only into the clamping shoe or-collar. Therefore, the rod 9' can slide freely through the coupling when said pressure is applied. The rod 9, of course, maintains its screw thread engagement with the clamping shoe. When the parts have thus been thrust to the right, the whole coupling may be moved up or down along the upright until the desired opening is reached, when, by removing pressure from the hand wheel, the spring 23 may exert its force to press the friction or clamping shoe toward the left, and thus cause the pin carried thereby to enter the opening in the upright, and this r position having been reached, the parts may be clamped by turning the hand wheel 12' so that the screw rod 9 will move inwardly in respect to the clamping shoe, and the hand wheel having become seated against the exterior face of the coupling, further rotary movement of said hand wheel will cause the screw rod 9 to draw the clamping shoe tight against the upright, and thus securely clamp the parts in place. If it is desired to hold the clamping shoe with the pin retracted in relation to the upright, the button 26 may be turned after the shoe has been pressed toward the right, and this will bring the extension 27 of said button against the pin 2a to hold it at the extreme right of the slot 25. It will be seen that in this form as well as in the form first described the clamping of the coupling to the upright is done by a friction shoe which has a move- The clamping shoe is pressed ing surface of the curved shoe,

' right,

ment directly toward and from the said upright, and whose contact is by direct pres sure as distinguished from a sliding, grinding or turning pressure, and thus marking oft-he finish of the upright is avoided.

My invention is distinguished among other features by having a clamping shoe of curved form extending beyond the clampand a spring for causing the pin to enter the openings in the upright however these parts may be arranged or combined.

I claim as my invention:
