UNITED STATES PATENT OFFICE.
NICHOLAS W. AKIMOFF, OF WYNNEWOOD, PENNSYLVANIA, ASSIGNOB TO GENERAL MACHINERY FOUNDATIONS COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A
CORPORATION OF DELAWARE.
HINGE CONNECTION.
Application filed August 12, 1920. Serial No. 408,120.
To all whom it may concern Be it known that I, NICHOLAS W. AKI- -MOFF, a citizen of the United States, residing at Wynnewood, in the county of Montgomery and State of Pennyslvania, have invented certain new and useful Improvements .in Hinge Connections, of which the followin is a specification.
y invention relates to hinge connections, that is to say, to an article of manufacture which is adapted for use as a hinge joint for machine parts having relative angular movement about an axis with respect to each other, and of small angular amplitude. More specifically considered, my invention relates to a rolled metal shape, which is adapted to be embodied in a variety of forms, nd which will be found to have many practical applications. For example, a short length of the same may be used as a connection for pendulums used in various scientific tests where the motion must be uniplanar, or as a component part of apparatus for investigating vibratory motion, or as a component part of apparatus which is constructed and'arranged for supporting ma chinery in such manner as to mlnimize transmitted vibratory effects.
The principal object of my present IHVGII' tion is to provide a new article of manufacture having valuable characteristics for the aforesaid purposes, which will be relatively inexpensive, yet durable and efiicient for 1ts intended purposes.
The nature and characteristic. features of my invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part hereof, in which,
Figure 1 is a transverse section of a rolled metal shape embodying the main features of my invention;
Fig. 2 is a similar view of a modified form of the shape shown in Fig. 1;
Fig. 3 is a transverse section of another form or embodiment of my invention;
Fig. 4 is a similar view of a modified form of the shape shown in Fig. 3; and
Figs. 5, 6 and 7 are transverse sections of other forms or embodiments of my invention.
Referring now more particularly to Fig. 1 of the drawings, my invention is therein Specification of Letters Patent.
Patented Sept. 6, 1921.
shown as embodied in a rolled section, preferably made of steel or steel alloy, and comprlsing a top flange 10, and a bottom flange 11, which flanges are provided for the purpose of attaching a suitable length of the rolled shape t the machine elements or parts in connection with which the same is to be used. Extending between the flanges 10 and 11, is a web portion 12, which is made rela tively heavy except for a short portion thereof where the same is reduced in crosssection, as at 13.
' The form shown in Fig. 2 is substantiallv similar to that shown in Fig. 1, except that the reduced portion 13 is located intermediate the flanges 10 and 11, instead of contiguous to one of said flanges. llt will be noted that the forms shown in Figs. 1 and 2 are somewhat similar to the ordinary rolled I beam section, except for the difl'erences therein, as above noted, which are provided for the purposes of my invention.
In Figs. 3 and, there are shown embodiments of my invention in forms similar to the ordinary Z-bar rolled section, with the exception, as in the preceding forms, that the connecting web 12 is relativel heavy, and that at one portion thereof there 1s provided the reduced portion 13, which may be arranged contiguous to one of the flanges 10, as in Fig. 3, or intermediate the flanges 10 and 11, as in Fig. 4.
In Fig. 5, there is shown a form or embodiment of my invention similar to the ordina rolled angle section. For the purpose o explanation, the portions thereof adjacent the corner of the angle may be regarded as functionally similar to the web 12, which extends between the flanges in the previous forms so that the same may be regarded as havmg attaching flanges 10 and 11, with the web portion 12 of relatively heavy cross-section interposed therebetween, which web portion 12 is provided with the reduced portion 13.
In Fig. 6 there is shown a form or embodiment of my invention in a sha e similar to the ordinary T bar rolled section having an attaching flange 10. The outer end of the leg of the T bar section may be regarded as the attaching flange 11, and the portion of said leg adjacent the flange 10 may be regarded as the connecting web 12 i of relatively heavy cross-section, and having areduc'ed portion 13, preferably located contiguous to said flange 10.
In Fig. 7 there is shown another form or embodiment of the invention, comprising a flat bar, in which, for the purpose of explanation, the ends thereof may be regarded respectively as the attaching flanges l0 and 11, and the intermediate portion thereof may be regarded as the connecting web 12 of relatively heavy cross-section, with a reduced portion 13 provided therein.
It will be seen that in all of the various forms or embodiments of my invention, the same are characterized by having attaching members or flanges 10 and 11, which are connected to each other by a web portion of relativel heavy cross-section, whichweb portion is provided with a reduced portion of relatively small linear dimension. By this arrangement, the web portion of relatively heavy cross-section will prevent deformation of the section which would result in sidewise movement of an objectionable character, and will limit the movement to an angular character about an axis located within the area of the reduced portion.
When a suitable length of the rolled section of any of the forms shown is interposed between two machine parts which are designed to have small angular motion with respect to each other the reduced portion 13 will constitute a, fulcrum for angular movement which, on account of the relative motion being small, will be substantially frictionless, as it will be readily apparent to those skilled in the art that the only friction existing will be that of a molecular character, resulting from the stretching and compressing of the fibers of the metal at the reduced portion, and it may be demonstrated that, for the intended purposes of the invention, such molecular friction is substantially negligible; and in any event, there is rovided a hinge connection or fulcrum, whlch will be far superior, for the intended purposes, to any 'of the forms of pivot joints or rocker bearings at resent in use.
It will also be note that by making the hinge connection of my invention of a rolled sectlon, instead of machining the same from a solid bar, a beneficial effect will be obtained in that the better molecular condition of the fibers of the metal near the surface will exist substantially throughout the area of the reduced portion 13, thus increasing the durability of the section in use, notwithstanding the small angular motion between the machine parts in connection With which the device is used.
Having thus described the nature and characteristic features of my invention what I claim as new and desire tosecure by Letters Patent, is:
1. A. new article of manufacture comprising a rolled metal shape having attaching members, and a web portion connecting said attaching members, said web portion being in the main relatively heavy, but having a reduced 'po-rtion forming a fulcrum for angular motion of parts to which the shape is attached.
2. A new article of manufacture comprising a rolled metal shape having attaching members, and a web portion connecting said attaching members, said web portion being in the main relatively heavy, but having a. reduced portion forming a fulcrum for angular motion of small amplitude of parts to which the shape is attached.
3. A new article of manufacture comprising a rolled metal shape having attaching members, and a web portion connecting said attaching members, said web portion being in the main relatively heavy, but having a reduced portion of small linear dimension forming a fulcrum for angular motion of parts to which the shape is attached.
In testimony whereof I have hereunto signed my name.
NICHOLAS W. AKIMOFF.
