ADJUSTABLE TELESCOPIC CONNECTION` FOR DOOR-HOLDERS AND THE LIKE.
Specication of Letters Patent.
Patented Jan. 18,1921.
pplication led March 24, 1920.. SerialvNo; 368,269.`
To all whom-imag concern'.
Be it known that I, NORMAN B. HURD, a citizen of the United States of America, residing at New Britain, Connecticut, have invented a new and useful Adjustable Tele`- justers, the purpose of the device in such a connection being to frictionally hold a casement window in whatever position it may be placed, that is to say, either closed, fully opened or partially opened. By my im provement different degrees of frictional resistance to the sliding movement of the telescopic members may besecured lwithout the use of any special tool as will hereinafter be plainly seen.
In the drawings: 4 Y
Figure 1 is a plan view of the top of a easement window with my invention applied thereto.
Fig. 2 is a front elevation of the same.
Fig. 5 is a sectional view of a slight modi fication.
Figs. 6 and 7 are respectively a sectional view and a side elevation of another modification.
1, 2 are telescopic members. The part 1 is in the form of 'a rod, while the part 2 is in the form of a tube within which therod l slides. These parts may be respectively connected to a hinged easement lwindow 3 and the overhead part of the casing 4 by means of suitable brackets 5--6. Obviously, if a frictional resistance is introduced to retard the freedom of telescopicmovement, `it follows that the window 3 will be prevented from freely swinging and willbe held :in the closed position or at anyv angle to which itis opened. I have invented what I believe to be a novel means for providing the aforesaid frictional resistance and for permitting said means to be adjusted so as to afford varying degrees of resistance.
In the drawings, it will be seen that the rod 1 is provided with a friction head which slides with friction resistance in the tubular member 2. In the form shown in Figs. 3 and 4, this friction head comprises three tubular members 7, 8 and 9. These three members are mounted on the inner end of the rod l preferably in the manner shown in the sectional view, Fig. 8, in which it appears that the end of the rod is turned down and provided with a screw thread 10. The mem ber 7 is provided with a thread to correspond with the threaded part 10. The member 8 is provided with a central bore somewhat larger than that part of the rod passing through the same. The member 9 is loi cated on the rod so as to bear against the member 8 on the opposite end from the member 7. 1l is an abutment. l2 is a spring located between the abutment and the member 9. As shown, the adjacent ends of the three tubular members?, 8 and 9, are beveled, so that if the members 7 and 9 are moved toward each other, the member 8 will be pressed laterally by the wedging action of the members 7 and 9 against the beveled ends` of the part 8. When the parts are assembled, as shown in Figs. l and 2, the desired degree of frictionalresistance to a telescopic sliding movement may be secured by removing screw 5 and simply turning the rod lin the tube 2 or vice versa. This turning movement causes the screw 10 to turn in the part 7 so as to move it in the desired direction. Assuming it is desired to increase the friction, the rod l is turned in a direction to draw the part 7 toward the part 9. This forces the part 8 laterally relatively to the parts 7 and 9, andV hence the said friction head is relatively expanded so as to fit more snugly in the tube section 2 and thereby offer an added degree of friction to sliding move ment. By this very simple expedient and without the use of any special tools, the desired degree of friction may be secured. The spring 12 serves to put a slight degree of tension between the interengaging threads so as to check any tendency of the part 7 to become accidentally unscrewed by jarring. This spring also compensates for wear and for expansion and contraction of the friction head. In Figs. 3 and l, I have shown the part 7 as internally threaded so as to turn on the threaded end 10 of the rod. If this member 7 should be made of relatively soft metal, which for the purposes of friction may be preferable in some cases, it may be desirable to provide a bushing of hard metal to receive the thread. To that end I have shown in Fig. 5 a modification in which the part 72L corresponds to the part 7 shown in the other views excepting that it is provided With a hard metal bushing 7", which latter is threaded.
In Fig. 6 I have shown the friction head as being made of two tubular pieces 14, 15, instead of three pieces. It will also be seen that in this instance I have provided the piece 15 with the hard metal insert 7b, which latter is threaded to turn on the thread 10` as in Fig. 5. VVh'en the rod 1 is turned, the parts will be acted upon as in the previous case, that is to say, if the rod 1 is turned in the direction to draw the part 15 toward the abutment 11, it will tend to force the other part 14 laterally, as shown in Fig. 7, thereby more tightly fitting in the complementary tubular member so as to produce the desired degree of resistance to sliding movement. The several pieces of the friction head in all cases may be made of any desired material best adapted to withstand wear due to fric* tion. But I do not intend to limit myself to the selection of any particular material or metal, although obviously, some materials and some metals are preferable to others, the particular selection being left to the skill of the mechanic.
