To all whom t magi/ concem:

Be it known that I, WILLISIC. JACOBS, a citizen of the United States, residin at St. Paul, in the county of Ramsey and tate of Minnesota, have invented certain new `and useful Im rovements in Jaw Slides, of

- which the ollowing is a specification.

My invention relates to improvements in jawslides for awnings and the like, and has for its object to provide an improved slide for movably supporting the awning frame which can be placed upon, or removed from, the slide bar while the same is in place upon a building.

To this end the invention consists in the construction, combination Aand arrangements' of parts hereinafter described and claimed.`

In the accompanying drawings forming part of this specification, Figure 1 1s a side elevation of a part of the awnin frame showing my improved slide; Fig. 2 .is a erspective view of the slide alone 1n p ace upon a fragment of the slide bar; Fig. 1s a perspective view of the two cobperating jaw members of the slide; Fig. 4 1s a cross section on line --w of Fig. 2; Fig. 5 is a perspective view of a'fragment of the jawslide showing the interlocking connections of the jaw members; Fig. 6 is a top view oflthe slide members or jaws in position to be moved into locking engagement; Fig. 7 is a perspective view of amodified 4form of j aw slide in place upon a fragment of a slide bar; Fig. 8 is a top view of the'structure shown. in Fig. 7; and Fig. 9 is a perspective view of a fragment of each 'of thel slide members shown in Fig. `7 in position to be moved into locking engagement.-

In the drawings AY represents the wall upon whichthe awnin is supported, and 2 a vertical slide bar bo ted or otherwise selcured at top and bottom upontheface of the wall. This bar is here shown rectangularin cross section, and maybe securedupon the wall with its front and rear faces parallel therewith as shown in Fig. 2, or with its ad jacent sides set at an angle of 45 degrees therewith, as shown in Fig. 7. Between its secured ends the bar is spaced apart from the wall to allow the jaw slide to work freely up and down. y

The A jaw slide comprises two separable members or jaws 8 and 4 adapted to fit slidably about the slide bar 2, and having at the front ears 5 adapted to be pivotally secured to the side bar 6 of the awning frame.

. of 90 degrees, so as to fit against the sides of the slide bar, the front an These jaws interlock at the rear, andare detachably secured together in front of the slide bar by means of a screw or bolt 7, 'whlch passes through a hole 8 in one jaw and .is threaded into an apertured lug 9- upon the inner face ofthe other jaw, the lug being preferably long enough abutment for the jaw having the hole 8. Upon the innerface of the jaw 3 which carries the lug 9 are apair of spaced studs 10 arranged in vertical alinement above and below the lug. Uponthese studs are journaled a pair of rollers in position to engage and having rolling contact withthe front of the slide bar.

In the embodiment of the invention shown to form an upon a rectangular-slide bar having its front and rear faces parallel with the wall A, the

innersides of the jaws are flat so as to fit against the flat sides of the slide bar, and are formed with perpendicularly inturned arms 11 which fit slidingly against the rear side of the slide bar and formthe back wall of the jaw slide. In this form the rollers 12 journaled uponA the pins 10 at the front of the slide bar have a Hat tread or periphery so as to work upon the face of the slide bar 'in coperation with the arms 1-1 at the rear.

In the jaw slid'eshown in- Figs. 7 and 8,

which is designed for use with a square slide j bar arranged with its sides at an angle of 45 degrees with the wall, the jaws have an la'r arms 13 extending first out at an ang c ,of

135 degrees with the plane of the jaw sides and then in toward each other at an angle uared rear edges of which will be in the vertical plane this form the rollers, which are here numbered 14, are vcentrally grooved at 15 to receive the front edge 16 of the slide bar. The bar is thus movably held between the grooved rollers 14 and the angular arms 13. AThe jaws of the slide may have any sort of interlocking connection at the rear of the slide bar which will enablethem to be conveniently connected or disconnected after Vthey have been put in place upon the bar,

and which will not interfere with their free movement upon the bar. In Fig. 3 of the drawings I have shown a dove-tailed connection between the ends of the arms 11 consisting of curved mortises 17 in the arms of one of the jaws and similarly shaped 'which lies centrally between the jaws. In

jaws on the slide bar with one slight inv #advance of the other, as illustrated in ig.

6, and then drawing the rear jaw horizontally forward until the tenon ent-ers the mortise and the arms stand in alinement.

In Fig. 9 of the drawings I have shown another form of interlocking connectlon consisting of vertically rabbeted grooves 19 and projections 20 in the underside of the arms 13 of one of the `jaws and c ooperating grooves 21 and projections 22 1n the upper side of the arms of the other jaw. With this form of lock joint the jaws are placed upon the slide bar with one slightly above the other, as illustrated in Fig. 9 and then drawn vertically .toward each other so that the projection 20 will t into the groove 21 and the projection 22 into the groove 19. rlhe side bar 6 of the awning frame is pivotally secured between the ears 5 of the jaws by means of a pivot 23. rlhis frame is foldably secured upon the wall A by means of ajlink 24 pivotally secured at the top to the wall and at the bottom to the side bar 6 of the awning frame some distance in front of the jaw slide.

In use the aws 3 and 4 are first placed on the opposite sides of the slide bar with the inturned arms 11 or 13, as the case may be, between the back of the bar and the wall A. With the form of interlocking connection shown in Fig. 3 one jaw is first placed a lit. tle rearwardly of the other, and then drawn forward as above described to bring the mortise and tenon into locked engagement, while with the form of connection shown in Fig. 9 one jaw is placed a little above the other and then drawn down to bring the rabbeted grooves and projections into locked engagement. 'llhe jaws are then secured together in front of the slide bar by.

same has been secured upon the wall, where-1 as, with a one part slide, the slide must be fitted over the bar before the ends thereof 'have been bent and flattened to enable it to be secured upon the wall. And of course thcpresent two part slide can be taken apart and removed from the slide bar whenever desired without removing or cutting the bar.

lVhile in the drawings I have shown a jaw slide having a rectangular slide-way designed for use with a slide bar of rectangular section, it will be understood that the invention is not limited to a slide-way of any particular shape, for its shape will obviously depend upon the sectional shape of the slide bar upon which it is designed to be used.

I claim as my invention:

The combination with a slide bar, of a jaw slide comprising two separable jaws having inturned interlocking arms at the rear of the slide bar, rollers journaled between said jaws at the front of the slide bar, and an interiorly threaded spacing lug carried by one of the jaws near said rollers, said lug forming an abutment for the other jaw and being adapted to receive a fastening bolt in its aperture, said arms and rollers embracing the slide bar between them.

In testimony whereof I aiiX my signature in presence of two witnesses.
