Application filed January 23, 1922. Serial No. 531,063.
To all whom it may concern: v r
Be it known that LCHARLns Gr. PALMER,
v a citizen of the United States, residing in Newark, in the county of Essex and State of New Jersey, have invented certain new and useul Improvements in Rod Connectors, of which the following is a specification.
The object of the invention is to provide means for connecting the ends of rods with other mechanical elements in such manner I 'bracket12, through which extends the bolt as to admit of relative adjustment and firm clamping when the desired adjustment has been; made. I Another ob ect is to afford means whereby the engaged element is pivotally secured to the connector, the pivot having means by which it may be manuallyretracted, or held in operative position by other meansformed with the connector.
A further aim is to provide a simple connector, of the type described, capable of being made from a single blank of shoe metal or a casting aspreferred.
These purposes are attained by the novel design and construction of parts, hereinafter described and shown in the accompanying drawing, forming an essential part of the disclosure, and in which Figure 1 is a fragmentary sectional view showing the application of the connector to a door latch operating'devicer- Figure 2 is a front elevational view of the connector as engaged with associated parts.
Figure is a side view of the device in dctail.
Figure 4 is an end view of the same. Figure 5 is a rear elevational view showing a modified form of construction.
Figure 6 is a plan view of the blank from which the preferred form of the connector .is made.
In the adaption shown the connector is indicated as engaging between the slidable rods or bars of a door latch bolt, of the type known as panic bolt, in which it may become necessary to instantly release it in order that the door can be opened hurriedly, as in the case of fire or like emergency.
In installing such devices difiiculty is often encountered in obtaining the exact length of the operating rods, which obviously must be accurate in order that the device function properly, and to avoid such trouble has been the main purpose of the, lnvention.
its length; 1
' However,- it will be apparent that a wide variety of other like mechanisms may be satisfactorily served by the device. v
InF'gure 1 the numeral 10 designates th frame or jamb of thefdoor 11, to the inner side of which are engaged brackets 12Land- 13 respectively near its top and midway in A keeper 14, fixed in the jamb, is adapted to receive a latch bolt 15 'slidable in the shank 16, secured to a rod 17 by a'connector 18 and operatively engaged in the bracket .13 by the actuating leverhandle 19. The preferred form of the connector is made from a sheet metal blank, shown in detail in. Figure 6, consistingof an elongated body having between its sides 20'and 21 a slot 22." At each end 23 and 24; are pairs of perforations 25-25 and 26'-26, the corners being rounded as shown.
tions 29 and 30 respectively. H v
Extending out fr m'the ar 28,:are opposed lugs 31 adapted to be bent on thelines 32 to stand substantiallyparallel.
The ends. 23:2t are sharply bQIltOILllIlGS registering with theends of the slot 22 and the sides 20--21. are formed to present'Jcir-1 cular bands from which the elements 23-24 extend parallel and closely adjacent toeach other (see Figures 2 and 4) the bands being fitted to a rod or bar as the element 17 and tightly clamped therearound by bolts or screws 33, passed through the perforations 25 and 26 and provided with nuts 34.
The arms 27 and 28 are offset, curved and bent to constitute forks engageable with the element 16 and held thereto by a pin 35 pass ing through the perforations 29 30 and a corresponding hole in the element 16.
One of the ends of the pin 35 is bent at a right angle 36, turned to extend between the lugs 31, which project outwardly beyond the element 36, and when bent inwardly toward each other, as sho-wnin'Fig ure 4, maintain the pin securely but removably in position. I I I 7 While the foregoing applies more particularly to a sheet metal connector, it will be understood that the same may be cast the same general characteristics are observab.le,'theElugs13lghowever being omitted and the pin fixedly engaged in the element 16, the arms, when the bolts are relaxed,
bein sutficientlv elastic to sarin out and" allow the pin to enter the perforations, whereupon the clamp screws securethe device in posit-ion.
From the foregoing it will be seen that an extremely simple one piece connector has been disclosed, readilyadjustable on the element 17 so that the latter can be moved relative to the element 16 and then rigidly clamped, the element-16 pivoting on the pin if suchuaction is desirable.
WVhile certain preferred embodiments of this device have been shown and described, it will be understood that changes in the form, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention, as defined in theiappended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, 1s 2-.-
1. A device of the class described comprising a. band having spaced ends, means for contracting saldband,opposed arms extending fromeone edge of said band, and means passing through said arms for removably engaging an article withsaid band.
2. A device of (the class described comprising a pair of bands having out-turned flanged ends connected between the bands, arms formed on opposite sides of one of said bands, said arms being 'pertoratedin register, all of said elements being integral, a pin engagingin the openingsm: said arms, and clamp bolts operatively engaging the flanged ends of said bands.
3. A devieeofthe class described coinprisingone or more bands, means it'or contractmg said bands, off-set arms extending in opposed relation from one of the bands equidistant and parallel with the axis of the band, a pin fitting holes in said arms, said pin being positioned diametrically across the opening inythe band, and an angular extension on said pin whereby it may be manipulated.
4;. A device of the class described comprising a pair of spaced bands integrally united at their flangedyends, bolts adapted to clampisaid ends, a pairot arms extending tt'ron'i opposite sides of one of said :bands, 7
a pin passing through said arms, and means for maintaining-said pin when assembled.
