P. F. FROST FENCE CONSTRUCTION Filed May 1923 IN VENTOR Parmenas F first ATTORNEYS,
Patented Aug. 4, 1925.
UNITED STATES PATENT OFFICE.
' PARMENAS r. FROST, or MOUNT VERNON, NEW YORK.
FENCE CONSTRUCTION.
others skilled in the art to which it appertains to make and use the same.
This invention relates to fences and more particularly to that class of fence commonly known in the trade as non-climbable fence.
It has heretofore been common practice in connection with fences of wire mesh and other construction toemploy one or more strings of barbed wire at the top of the fence for the purpose of preventing persons from climbing over the fences, or if not positively preventing them to at least deter them. The ordinary barbed wire heretofore employed has been objectionable as unsightly and as not being strong or permanent enough to meet the requirements.
The objects of the present invention are to provide an improved type of flexible barbed or pronged device for use in connection with fences; to provide a device which is strong and at the same time -flexible; to provide a device embodying neatness of appearance and at the same time economical to manufacture; to enable the device to provide a plurality of barbs or prongs so as to be effective and at the same time of such structure. as not to materially increase the cost by the use of the prongs.
Referring to the accompanying drawing in which like numerals of reference indicate similar parts throughout the several views.
Figure 1 is an elevation of a fence embodying the present invention;
Figure 2 is a detail view in elevation of a portion of the flexible device;
Figure 3 is a cross sectional view on line 3-3 of Fig. 2.
In the specific embodiment of the invention illustrated in said drawing, the reference numeral 1 indicates in general the fence consisting of suitable post 2 for supporting the same, wire mesh 3 and flexible device 4. As shown in Fig. 1 the said flexible member 4 is preferably positioned along the top of the fence and carried by posts 2 for preventing or deterring persons from getting over the fence.
Application filed May 5, 1923. Serial No. 636,911.
The flexible device 4 is preferably constructed in the nature of a chain. Referring to Figs. 2 and 3, it is to be noted that the said flexible device or chain consists of a plurality of links 5, said links each consisting of loops 6 and 7 arranged transversely to each other. Preferably the link 5 consists of an integral piece of wire which forms both of saidloops 6 and 7. By means 'of' .this construction the several links may be interengaged so as to position them all alike in the series or chain and thereby obtain a symmetrical and neat appearance.
The ends of the wire comprising each link 5 are preferably constructed to constitute barbs or prongs 8, 9. By reference to the drawings it will be seen that the end of the wire forming one loop projects slantingly through the other loop and provides a pointed end at a distance from the plane of the second loop so as to be in position to readily engage apersons clothing in endeavoring to pass by the chain close to it. The arrangement is such that prong 8 of one link is directed transversely with respect to the other prong 9 of the same link, and in this way each link will provide prongs trans-verse to each other so as to insure engagement of one or the other should some one endeavor to pass close to the chain.
In carrying out my invention I prefer to construct all of the links alike, so as to make assembly very simple and also to increase the etficiency of the chain as a means of preventing persons from passing over the same. However it is to be understood that it is within the scope of the present invention to vary this construction, it not being considered that the present invention is necessarily restricted to each of the links being alike or each of the links being arranged the same as all other links.
Having thus described my invention, I claim- A link for a barbed chain comprising a wire bent to form a pair of loops arranged in different planes, the wire terminals being directed towardthe opposite ends of the link and at an angle to the respective loops and themselves, the said terminals extending through the opposite loops and constituting barbs. I
In testimony whereof I aflix my signature.
