L. W. TIFFANY. LEVEL ATTACHMENT.
FILED NOV-8,1921- WITNESSES $24M: L0
ATTORNEYS rinvniiFarr"w. 'rrrraiuvpor wins'rnn, connnorrcur.
Application filed. November 8,1921. "Serial No. 513,675.
To all whom it may concern: Be it known that I, Lnvnnn'r'r W; TinrANY, a citizen of the United States, and
resident of lVinsted, in the county of Litchfield and State of Connecticut, have invented a new and Improved Level Attachment, of which the following is afull, clear, and exact description. 1
My invention relates to an attachment, and more particularly aims to provide a device of this nature which is intended to be associated with a level. i
It is an object of this invention to pro vide a device of the character stated which may be manufactured at a nominal figure and which may be applied to a standard type of level, and by means of which the distance between two planes extending in a single surface may be measured.
Still another object of this invention is the provision. of an attachment of the type specified which shall be similar to the at tachment described in my co-pending application Serial No. 513,674, filed Nov. 8, 1921,
but which is ideally adapted for use in connectionwith work which requires great exactitude,
Still further objects of this invention will become apparent in the annexed specification taken in connection with the drawings,
which latter illustrate one practical embodiment of the same, and in which- Figure 1 is a side elevation of a level and showing my improved attachment associated with one end thereof. a
Figure 2 is a fragmentary partly sectional enlarged view of the end portion of a level showing the attachment in position thereon, and a I Figure 3 is an end View thereof with certain parts broken away to illustrate the underlying construction.
in my application afore referred to, the reference numeral 5 indicates the body of a level with which the registering element 6 is associated, it being understood that the level may be of any desirable character, and material, and that these elements may be in the nature of tubes or other elements, as is most desirable.
Referring to the construction of the attachment it will be seen that the same primarily includes a preferably U shaped plate 7 formed with a cutout portion 8, this cut out portion, when the plate is in applled position, aligning with aslot 9 in the body :3
tending end portions 13 terminating in pointers 14 which are adapted to register with graduations 15 formed on the exterior face of the plate.
Now with a view of movingthe stem 10 transversely with respect to the body of the level, it will be seen that the cutout portion 9, and the opening 8 of the plate accommodate the screw threaded washer 16, which latter includes the threads of the stem 10. Thus upon an operator rotating the thumbscrew 16 it will be understood that the stem 10 will be prevented from rotating incident to the flattened shoe 11, but this stem, together with the said shoe will be caused to move transversely of the level body 5. Also incident to the association of the plate 12 with the stem the latter will be prevented from rotating, and the outer portions of the same will slide along the exterior faces of the plate 7 and serve by means of the pointers 14 and graduationslo to indicate the position of the stem.
Thus an operator is enabled to place the level upon a supporting surface, and to actuate the washer 16 to cause-thesame to be positively moved in the manner afore-described, and when the shoe 11 elevates one end of the level to a point at which the indicating elements 6 of the same show that the body of the level is in a horizontal plane an operatormay accurately determine the distance to be measured by reading the graduations 15 by means of the pointers 14.
Obviously numerous modifications of structure might readily be resorted to withmy claims; which are:
1. A. level attachment including a plate, a
stem, ashoe forming a part of said stem,
means for moving said stem with res set to said plate. and a second plate carried y the upper end of said stem and having a portiondownbent and terminating in a pointer lying opposite the first-mentioned plate,.the
latter plate carrying ascale having graduacarried by the upper end of said stem, said latter plate being formed with dmmwnrdly turned end portions terminating in pointers, said pointers being adapted to align with graduations formed in said first named plate.
