(lite emu UNITED STATES PATENT OFFICE.
NORMAN B. HURD, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THEAMERIOAN HARDWARE CORPORATION, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CONNECTICUT.
ADJUSTABLE TELESCOPIC CONNECTION, FORDOOR-HOLDERS AND THE LIKE.
Specification of Letters Patent.
Patented Jan. 18, 1921.
Application filed March 24, 1920. Serial No. 368,270.
To all who m. it may concern Be it known that I, NonnAN B. Hum), a citizen of the United States of America, residing at New Britain, Connecticut, have invented a new and useful Adjustable Telescopic Connection for Door-Holders and the like, of which the following is a speclfication.
My invention relates to an improvement in telescopic extensible members which is particularly useful in such constructlons known as casement window holders or adjusters, thepurposeof 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 improvement different degrees of frictional resistance to the sliding movement of the telescopic members may be secured without the use of any special tool as will hereinafter be plainly seen.
In the drawings:
Figure 1 is a plan view of a casement window with my improvement applied thereto.
Fig. 2 is a relatively enlarged sectional view showing certaindetails of construction, and certain parts being shown in elevation. jj
Fig. 3 is a similar view showingthe same parts in a slightly dilferent'position.
Fig. 4. is a relatively enlarged sectional view of what I shall term the friction head and its associated parts.
F ig. 5 is a similar view showing the same parts in a different position of adjustment.
Fig. 6 is a side elevation of the friction head.
1 represents a rod which is telescopically slidable in a tube 2, the said parts being provided with suitable means for frictionally resisting a sliding movement so that the telescopic members may be moved to different holding positions. In the form shown in the drawings the device is applied as a casement window holder in which'3 represents a hinged casement window socalled. The rod 1 is connected by a bracket 4 to the window while the tube 2 is connected by a bracket 5 to the window casing. Obviously as the window 3 is opened the telescopic parts are extended. It follows that if there is a proper resistance provided against sliding movement of the parts 1 and 2, the window 3 will be frictionally held in its closed position as shown or at any an-- gle to which it is opened. The frictional. means to which this invention particularly relates comprises a friction head mounted on the inner end of the internal member which is adjustable without the use of any special tools and by simply turning the rod 1 within the tube 2 orvice versa. Referring to Figs. 2 to 6, it will be seen that the friction head is in the form of a one-piece member comprising a ribbon of suitable friction material 'wound up in spiral form and loosely mounted'on the inner end of the rod 1 between abutments G and 7. 8 represents the friction head proper formed of the aforesaid spirally wound ribbon. The abutment 7 is movable on the rod by means of a screw thread. The inner end of the rod 1 is provided with a screw thread 1 and in this particular connection I preferably provide a special form of nut 9 which is threaded on the rod 1 and bears against the abutment 7. The outer end. of the nut may be provided with a recess 10. 11 is the hinge pin of the bracket 5, the intermediate portion of said pin being located withinthe tube 2 back of the nut 9. WVhen the parts are applied to a casement window. the same should be so applied that when the window is fully closed the friction head will stop in. substantially the position shown in Fig. 3, that is to say, before the nut 9 will reach the pin 11. Be fore the parts are actually set up, the mechanic adjusts the tension of the friction head so that it will. furnish the desired resistance to a sliding movement of the rod 1 in the part 2. This adjustment is effected by simply pushing in the rod 1 until the ends of the nut 9 onv the opposite sides of the recess 1.0 straddle the pin 11, then byturning the rod]. the nut is screwedup ordown on the threaded end of the rod so as to apply the desired degree of end pressure against the friction head. Obviously, if the friction head is compressed longitudinally it will, by reason of its spiral formation, be expanded laterally so as to more snugly bear against the internal wall of the tube 2. When it is found that the frictional resistance to a sliding movement has been satisfactorily secured, the rod is pulled out far enough to disengage the nut from the pin 11 and the bracket i is then attached to the easement Window, so that the aforesaid frictional resistance may be utilized to hold the Window in any position desired. Should the friction head Wear down in time, the tension of the same may be readjusted in the aforesaid manner by simply removing screw and turning the rod in a proper direction to screw up the nut as before described. Obviously, the abutment 7 may be a part of the nut 9 or separate, this modification being too obvious to require illustration. So. also the abutment 6 may be part of the rod 1, such modification being too obvious to require special illustration. The particular construction of the friction head proper may be modified in a variety of Ways so long as it is so constructed that the relative rotation of the rod 1 in the tube 2 serves. to vary the degree of surface tension between the friction head and the inner Wall of the tube.
What I claim is:
1. A pair of telescopic members, a onepiece friction head carried by the internal member and slidably fitting Within the external member, means for expanding said friction head controllable by rotating one of said telescopic members relatively to the other.
2. A pair of telescopic members, a screw thread on the inner end of the inner member, a one-piece friction head carried b the inner member and slidably fitting Within the external member, with means mounted on said thread and arranged to turn thereon for expanding said friction head.
3. A pair of telescopic members, a screw thread on the end of the inner member, a one piece friction head comprising a spirally Wound ribbon surrounding the inner member and carried thereby and slidably fitting the inner vall of the external member, and means mounted on the threaded portion of the inner member and rotatable thereon for compressing said friction head longitudinally to cause the same to expand laterally.
4. A pair of telescopic members, a screw thread on the end of the inner member. a one-piece friction head comprising; a spirally Wound ribbon surrounding the inner member and carried thereby and slidably fitting the inner wall of the external member, and means mounted on the threaded portion of the inner member and rotatable thereon for compressing said friction head longitudinally to cause the szune to expand laterally, said means comprising a nut ha ing a projection and a shoulder at the inner end of the external telescopic member for engaging said nut when the internal telescopic member is pushed fully into the external member whereby said internal member may be rotated while the nut is held against rotation by said shoulder.
