' scribed and claimed.
Referring to the drawings which accompany this specification and form a part hereof, which drawings illustrate an embodiment of 4this invention, and on which drawings the same reference characters are used to designate the same partswherever they may appear in each of the several views, Fig. 1 is an elevation of a collapsible pole, parts of the pole being broken away; Fig.
2" is an elevation of the pole in its collapsed condition, parts of the pole being broken away; Fig. 3 isan elevation of parts of the pole, drawn on a larger scale than Figs: 1 and 2; and Fig. 4 is a section on the line 4 4 of Fig. 1, looking in the direction indicated by the arrows, Fig. 4 being drawn to a larger scale than Fig. 1.
Referring to the drawings, the reference numeral 1 designates generally, a collapsible pole. The collapsible pole 1 is illustrated by the drawings as a tent-pole which is coniposed of lthe parts 2 and 3, the hinge member 4, and the spike 5. The members 2 and 3 are illustrated by the drawings as wooden members, and the spike 5 is a metal rod secured in the end of the member' 2 and intended to be passed through a grommet in a tent, not shown, in the usual manner.
The hinge member 4 is preferably comosed of four parts which can be readily ormed from sheet metal of sufficient thickness to afford the strength required for ythe dimensions of the pole and the service to which it is to be subjected, but the invention is not limited to such a. construction, such a construction being adopted for convenience of construction. Two of these parts are the plate members 6 and 7, which may be secured to the part 2 of the pole by rivets 8, and the other two of these parts are the plate members 9 and 10, which may be secured to the part 3 of the pole by rivets 8. The rivets 8 are simple means for securing the plate members to the parts of the pole and are used in preference to other devices because of their dependability.
The hinge ends of the parts 2 and 3 of the pole are in planes at right angles to the surfaces of the parts of the pole so as to abut squarely and the several plate members 6, 7,
of the pole. tion, for the moment, the force necessary to 9 and 10 are extended soas to project beyond the ends of the parts 2` and y3 of the4 pole and overlap the joint 11., as clearly shown by Figs. l and 2 ot' the drawings. Such a construction also provides for andV necessitates an Overlapping relation between the plate members 6 and 9.and. .the plate members 7 and 10, these pairs of plate members being secured to opposite sides off the pole as clearly shown by the drawings. The overlapping relation between plate members can be readily arranged. for in any suitable manner as, for example, by provid-` ing offsets 12 in plate members. 'lhe rivets 8 can be relieved from shearing stresses and the hinge ends ofthe parts 2 and 8 of the pole can be prevented from splitting by one or more tabs 13, left on the plate members, which are turned over against opposite sides oi" the parts 2 and 3, as clearly shown bythe drawings. The joint 11 is, of course, the part of the pole which must be made strong enough for the demands to be put upon it.' Now, looking at Fig. 3 of the drawings, it will be readily seen that, in order to bend the part 2 of the pole to the right or left with regard to the part 3 of the pole, one side Ot' the hinge end of the part 2 ofthe pole must be lifted, because the other side of the hinge end ot that part of the pole must be a fulcrum or turning place, owing to the abutting relationship of the hinge ends of the parts Omitting from this considerashear a hinge pin 14 or 15 and the pin 16, al1 of the four plate members 6, 7, 9 and l0 would have to be bent to permit of any such movement. Now, adding to the force required .to bend these plate members the force required to shear both a hinge pin and the pin 16, it will be readily seen that the pole is strong enough at the joint 11 in the direction'of possible failure which is under discussion.
TheV hinge pin 14 is illustrated as a rivet which hinges the plate members 6 and 9 together, and the hinge pin 15 is illustrated as a rivet which hinges the plate members 7 and 10 together. These two hinge pins are axially in the same line and they and the pin 16 are intersected by a plane coinciding with the joint 11. The pin 16 is illustrated as a cotter pin which can be passed through holes. 17, 18, 19 and 2() in the plate members 6, 7, 9 and 10, these holes being in an axial line when the parts 2 and 3 of the pole are turned into positions in which the pole is in its extended position. The pin 16 may be fastened to a part of the pole by a flexible member ,21 which is secured to a part of the pole in any suitable manner. yThe overlapping parts 22, 23, 24 and 25 of the plate members 6, 7, 9 and l() extend outward beyond the pole, as clearly shown by Figs. 1, 2 and 4 of the drawings, on both sides of the pole, to any required distance, depending upon the service to which the pole is to be put, to obtain sufficient leverage for the hinge pins 14 and 15 and the pin 16 to )revent the part 2 of the pole from being bent to the right or left, see Fig. 1 of the drawings, with respect to the part 3 of the pole. For the pole to fail at the joint 11 by a right or left movement of a member in the plane of the paper, looking at Fig. 1 of the drawings, both hinge pins 1li and 15 must be sheared and the pin 16 must be sheared in two places. It is evident, therefore, that by placing the hinge pins 11 and 15 and the pin 16 arenough away from the pole, their size can be reduced in accordance with their leverage distances.
The principles of construction and operation will be readily understood from the foregoing description and it will also be readily understood that the construction illustrated and described not only prevents bending at the joint but also prevents relative twisting or torsion at the joint as between the parts 2 and 3 of the pole.
It will be readily understood that the function of the pin 16 is to lock the parts 2 and 3 of the pole in alignment, or in cxtended positions and that the free ends of the Cotter pin 16 may be bent apart in the well-known manner for further security, if desired. `By removing the pin 16, the parts 2 and 3 of the pole are free to be collapsed into parallel positions, as shown by Fig. 2 of the drawings.
lVhat is claimed is:`
A collapsible pole of the type having a plurality of parts abutting in end to end relation when the pole is extended and disposed in substantial parallelism when the pole is collapsed and provided with T- shaped members comprising elongated fiat Shanks fitted upon and fixed to opposite sides of said parts at the adjacent ends thereof and head portions at the outer ends of said shank extending transversely thereof for the full width of the Shanks and having lateral extensions projecting beyond the opposite sides of the Shanks and of the parts of the pole, certain of said lateral extensions overlapping in all positions of the parts, means for pivotally connecting said overlapping extensions in such manner that the head portions overlap for their entire extent when the pole is extended, and a relasable locking means for holding the parts ot the pole extended.
In witness whereof I hereto aiix my signature.
