Application mea November 27, 1925. serial No. 71,6'5.
Our present invention has for its object to provide a simple and highly elicient screw clamp intended for general use, but especially adapted for detachably securing interchangeably usable screen and glass panels on doors, and of the type disclosed and claimed in our two pending U. S. applications, one of which was -filed March 24, 1924 under Serial Number 701,421, and the other of which was filed December 19, 1924 under Serial Number 756,947.
To the above end, generally stated, th invention consists of the novel devices and combinations ot devices hereinafter described and defined in the claim.
In the accompanying drawings, which il lustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings:
Fig. 1 is a. front elevation of adoor having a removable screen panel held in position by a plurality of the improved screw clamps;
Fig. 2 is a fragmentary inside elevation o the door, screen anel and one of the screw clamps, on an en arged scale;
Fig. 3 is a detailview in section, takenon the line 3 3 of Fig. 2; y
Fig. 4 is a view principally in elevation showing the members of one of the screw clamps separated;
Fig. 5 is' a fragmentary detail view partly in elevation and partly in section showing, on an enlarged scale, the headed screw and the respective head member loosely applied thereto; andv l Fig. 6 is a view corresponding to Fig. 5, but'illustrating the head member rigidly secured to the headed screw.
I In the drawings, there is illustrated a door 7 .of the type having interchangeably usable screen and glass panels, the former 4of which is lshown andv indicated by the numeral 8. The outer edge portion of the panel 8 is rabbeted at 9 and mounted in a rabbeted seat 10 in the outer :tace of the door 7 Said screen panel 8 is removably h'eld in place by a plurality (as shown tour) of the improved screw clamps. 4
Each screw clamp comprises two disc-like head members 11 and 12, and a screw 13 4having a head 14 the under side ofl which is beveled andin the top of which is a channel 15 for the a plication of a screw driver for screw. The outer faceof the .head member 11 is convex 'and which head member has integrally formed with its back or inner face an axially projecting sleevelike body 16l having an internal :screw thread 17 and which body is applied Ito the .screw 13 as a nut. The .outer end .of the sleeveflike Cut and pressed from the peripheral edge portion of the head member 11 is .a plurality of inwardly projecting lugs 1S for holding said head member from turning at the time the screw 13 is applied thereto.
The headed screw 13 has a short unthreaded portion 19, just under its vhead 14, of a diameter slightly less than that of the diam-v eter ot the'thread 20 on said -screw. The screw thread 20 'is formed by pressing the same from the body of the headed screw 13, the original diameter of which was the same as that of the unthreaded portion 19. By thus forming the screw thread 20, thc same is pressed outward of the original diameterv of the body of the headed screw'13 thereby giving the 4same an external diameter greater than that of the unthreaded portion 19 of said screw. The head member 12 is provided with an axial bore 21 of such diameter as to permit said head member to be moved axially over the screw thread 2O and be positioned around the Unthreaded portion of the headed screw 13.- In the outer face of the head member 12 is a countersunk seat 22 for the screw head 14. The outer face ot the head member 12 is beveled from its countersunk seat 22 to its periphery.
After the head member 12 is positioned onto the headed screw 13 with its head 14 in the countersunk seat 22, an annular groove- 23 is pressed into the inner face of said head member. just outward of and concentric with its bore 21, to displace or contract the stock of the head member 12 at the bore 21 onto the unthreaded portion 19 of said screw and to a diameter less than that of the screw thread 20. as shown in Fia. 6, to hold the head member 12 on the hea ded screw 13.
1n applying the screw clamp to the door-7. aV hole 24 is bored into the outer face of said door to receive the sleev'e-like'body 16 of the head member 11'and permit the inner face ot' said head member to bear directlyon said door'. A relatively small bore .25, axially aligned withl the bore 24 is bored the rest of the way through the door 7 to receive the headed screw 13 which is screwed into the sleeve-like body 16 with the head member body 16 is closed by the head member 11. V
to clamp the head members 11 and 12 against' opposite sides of the door 7 and with the head member 12 overlapping and bearing against the frame of the screen panel 8, said panel will be securely but detachably secured to the door 7. lVhen turningr the screw 13 into the body 16 with the head member| 12 pressed against the door 7 and frame of the panel 8, said head member will be held by friction from turning, but the connection between the head member 12 and screw 13 is such as to permit the screw to turn in respent to said headmember. By contracting the stock of the head member 12 at its bore 21 into the unthreaded portion 19 of the screw 13 and back of the screw thread 20, said head member and screw are connected in assembled relation.
What we claim is: v
A screw clamp comprising two head members and a headed screw, one of said head members having an internally screwlthreaded sleeve-like body applied to. said screw.l said screw having at the under side of its head a short unthreaded portion of a diameter less than that ofthe thread on said screw, the other of said head members having a bore through which the headed screw projects and which headmember at its bore surrounds the unthreaded portion of the headed screw and has a countersunk seat in which the head of said screw is mounted, the stock surrunding the borein the last noted head member being upset onto the unthreaded GLEN ROBERTS.
