To all who/)L it ntay concern:

Be it known that l, ADAM J. ScnonNBoaN, a citizen of the United States, residing at Greenleaf, .in the county of Vashington and State of Kansas, have invented certain new and useful Improvements in Telescopes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an improvement in hand grips, more particularly to that type of hand grips known as telescopes.

The object of the present invention is the provision of a device of this character, the telescoping sections of which may be locked in various positions of adjustment so that they may be readily disengaged, without the use of straps or similar fastening means.

Other objects of the invention will be apparent from the detailed description hereinafter, when read in connection with the accompanying drawings forming part hereof, wherein a preferable embodiment of my invention is shown and wherein like numerals of reference refer to similar parts in the several views.

ln the drawings, Figure l is a longitudinal section of my improved telescope, and Fig. 2 is an end view thereof. i

Referring now more particularly to the drawings, A and B designate the upper and lower sections of the telescope, which are preferably formed of metal, and which telescope in the usual manner, the upper section A snugly fitting over the lower section B. Secured to the top of the upper section A is a handle a of any suitable construction. T he end walls of the lower section B are each provided medially thereof with a vertical row of apertures b therein. Secured to the inner faces of the end walls of the lower section B and covering the apertures l) therein are the vertically disposed arched plates t. The lower ends of the shields or plates t are preferably closed to prevent any extraneous .matter from working into the telescope through the apertures l). The end walls of the upper section A are provided medially thereof with spring catches7 which are designed to engage with the apertures l) in the end walls of the lower section B to lock the two sections together.

T he spring catches, above referred to, each comprise a strip of spring metal, which is rigidly secured at its upper end to the end wall of the upper section A of the telescope, and

1 which is provided adjacent the rear end thereof with an inwardly bent shouldered portion c which normally projects through an aperture a in the end wall of the upper section.

The shouldered portions c of the spring catches C are formed by bending the strip of which the catch is made inwardly at an abrupt angle and then bending the same outwardly, so that the lower-.end thereof will stand away from the end wall of the upper section A and constitute a handle for manipulating the catch to withdraw the same from engagement with the apertures l). The shouldered portions of the catches C are so fashioned that the lower faces thereof are beveled while the upper faces thereof project inwardly at substantially right angles from the end walls of the upper section A, so that when the upper section is lowered upon the lower section, the beveled portions of the catches C will permit the downward movement of the upper section to the desired eX- tent, but the sections cannot be separated until the hand pieces of the catches are manipulated to withdraw the shouldered portions c thereof from engagement with the apertures l) in the lower section B.

From this construction it 'will be apparent that in use the lower section is lilled and the upper section is placed thereover and moved downwardly as far as possible, the catches C engaging with one set of the apertures b in the lower section B and automatically locking the sections together. The shields ln serve to prevent the contents of the grip from interfering with the operation of the catches.

Secured to the end walls of the upper section A and extending across the apertures a/ therein are bars e2, wthich are adapted to contact with the inwardly bent shouldered portions c of the catches C to limit the outward movement thereof.

l do not desire to limit myself to the precise form and construction shown in the drawings, as it is obvious that many minor changes may be made within the scope ofthe appended claims without departing from the invention as defined in said claims.

llaving thus described the invention, what is claimed is z l. In a device of the character described, a lower section having a plurality of vertically disposed apertures in the end walls thereof, vertically disposed shields closed at their IOO IIO

lower ends secured to the inner faces of said end walls and covering the apertures therein, an upper section telescoping with said lower section and provided with catches coperating with the apertures in the lower section.

2. In a device of the character described, a section having a plurality of vertically disposed apertures in the end walls thereof, a second section telescoping with said iirst mentioned section and provided with openings in the end walls thereof, spring catches secured to the end Walls of said second section and provided with inwardly bent shouldered portions projecting through the openings therein said shouldered portions being arranged to co-operate with the apertures in the end walls of said first mentioned section when the sections are assembled, and bars secured across the openings in the end walls of said secondsection, said bars being adaptedto contact with the inwardly bent shouldered portions of the catches to limit the movement thereof. l

3. In a device of the character described, a section provided with recesses in the end walls thereof, a 'second section telescoped with said first mentioned section and provided with openings in the end walls thereof, spring plates secured at their upper ends to the exterior of the end walls of said section and provided vwith inwardly bent portions projecting through the apertures therein, the lower ends of said spring plates extending outwardly to constitute operating portions.

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