l INsUtAroR STACK.
. Application led May 19,
This invention relates to insulators and such as are commonly employed for mounting outdoor switches, busses and the like. p
Insulators of this t pe are generally formed by a plurality o units, each including a porcelain body portion having metal securing members 1n the form of metal llanges cemented to the top and bottom thereof. A number of .these units are mounted one upon another, by securing the top flange otV onev unit to the bottom flange of the next superimposed unit, so as to form a stack or post of any desired size. It has hitherto been vdillicult to properly align the various units ofv such a stack or pole, due to the fact that the metal flanges cannot be cemented to the porcelain with sullicient accuracy.
An object of this invention is to provide a device of the type set forth of such construction andarrangement that the parts thereo'tn can be easily and quickly adJusted and properly positioned, irrespective of any inaccuracy in the union of the parts.
A further object is to provide a device for aligning the separate units of an insulator post, which Will be simple in construction, effectivein operation and easy and cheap to manufacture.
These and other objects which will be apparent to those skilled in this particular art are accomplished by means of the lnventlon illustrated in the accompanying drawings, in which Figure l is a view in side elevation,
' partly in section, of an insulator post constructed in accordance with one embodiment ot' this invention. Fig. 2 1s a top plan view -of one form of an adjusting shim or washer employed in the assembly shown in Fig. l
and Fig. 3 is a side elevation thereof. p
The particular embodiment of this invention which has been chosen for the purposes of illustration consists of an insulator stack orpost 5 which is formed in the usual manner by a plurality of superimposed insulator unit-s 6 mounted one above the other to form a stack of any desired size. Each unit consists of a porcelain insulating member 7 having a metal connecting member 8 cemented to the top thereof, and a lower metal consecties member 9 cemented te the bvttcm 1927. Serial No. 192,509.
thereof. bviously, the connecting members may be of any desired form. The parts are assembled by securing the lower connecting member of one unit to the upper member of another unit, and it will be apparent that any inaccuracy, however slight, in cementing the metal members to the porcelain body portion of each unitwill result in such a misalignment of the units that the linished stack or ole will not stand perpendicular upon its ase.
ln order to permit the' ready andaccurateadjustment of the various parts in the field at the time the post is set up, the present invention includes the provision of sets of adjusting members or shims 10 between certain of 'the insulator units. Each member is in the form of .an annular ring of beveled shape., as shown in Fig. 3. In the particular embodiment which has been chosen for illustration, the annular ring is provided with slots 11 which cooperate With the securing bolts holding the adjacent units together so as, to hold the rings in operative position with relation to each other and to the associated units. It is, however, apparent that v or striking lug l2 so that the two shims of a set can be rotated relatively to each other for the purpose of producing accurate alignment of the various parts and for compensating for the misalignment resulting from the'inaccuracy in securing the metal flanges to the porcelain body portions. It will be found advantageous to use a pair et such adjusting members for approximately every iive insulator units. Thus, 'for eX- ample, a stack of eight separate units would employ two sets et shims, one near the bottom and one near the top of the stack.
lt will be readily apparent that rotation of one shim relatively to the other in any given pair will provide a micrometer adjustment of great delicacy which will permit the top of the stack 'to be accurately positioned as desired.
What l claim as new and desire to secure by Letters Patent is:
The combmatwn in an mauator Stack 0f a plurality of insulator units including connecting members, fastening bolts for securing said members together, a pair of beveled adjusting shims positioned between two of said members and having slots for receiving said bolts so as t-o permit relative rotation between said shiIns for varying the relative positions of said units and means on said shims for causing relative rotation therebetween.
In testimony whereof, I have hereunto subscribed iny naine this 13th day of May, 1927.
JOHN S. LAPP.
