advantages and capabilities as will hereafter appear and as are inherent inthe construction disclosed herein-.IY My invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawingr and, while I have shown therein what is'now` considered the preferred.embodiment of this invention, I desire the same to'be understood' as illustrative only and not to beinterpreted ina limiting sense. l f
v In the drawing annexed hereto and forming a part hereof, Fig. 1 shows my improved 'f apparatus mounted upon a supporting rod secured to a table or ledge of any accessible and convenient type; Fig. 2 is a faceview of the structure shown in Fig.1,v taken from the right side of that figure Fig. 3 is asimilar view showing the apparatus in use g' Fig 4 is a transverse section substantially along the plane indicated by the line 4-4 Fig. 2. Referencev will now be made in more detail to the annexed drawing in which a main upright meinberis indicated b y the numeral 1,
lthisrupright member having secured to its rear sidea pair of brackets 2 and 3 provided with openings 4 for the reception of the supporting rod 5. This rod is held inplace by a clamp 6 onV a ledge or table top 7. While.
it "isi not considered neces"sary,l fthe' bracket fjis;"preferably braced "by ftriangiilar` brace f8"vwhichfmalres the f structure more rigid* f simil-ai"bracje'fis located be` tweenf ther upright and 'al shelf 1011 adjacent "thebt'tlo'm of thejupright. iA-fseol I ond shelf `11 :is` secured tothe u'prightl and y has' an opening` 12l extending therethrough; This opening' is"-pi"eferably 'of substantially the fsarn'esize l asythe `opening?13-"in the shelf q 1O1and `is designed for the" reception` of a large tube 14: -A- smaller openingy lextends from opening 18-1throu`g`h the bottom/f the shelf 10 and 1is designed toreceive altube 16 which passes?therethrouglrffand through a stopper in`theflaottfom oftheltube14." 'In Fig. J t'hetube 16 is'shown'as' connected byafleitibietubeir 'with atttbe remmen-:dips t into f a ar 19 y containing 'l liquidi As" illusm trated invFi-g. 35 almeasurjisishowinbetween the tube f1`4 Vand i theupright- VL` Thi's scale may 'eitherbeca `sucjale secured to the glass tube,"` etched thereon, "mounted in* Lan opening inl the shelf` 11,` l or 'i otherwise l associated with the 5 tube "soE that it will' *bert possible to make readings in connection withthe t'ubej14 AK very convenient arrangement "of this is'to have a notch cutinfthe edgepfthe brace member9forthe reception ofthelower end of a meter'stick and a. corresponding opening cutv through the shelf 11 so that the meterstick can be inserted therethrough and into the notch in the brace 9; 4'Ihis brings the face of the meter stick close to the glass and `in a `convenient place to read. Openings 20 are formed in the upright 1 for any desired purpose, as, for example, the support of a tuning fork above the tube 14 when this apparatusl is used in the performance of experiments in sound. This apparatus is also used in the determination of pressure beneath a luidsurface and for various other experiments. It
is found extremely convenientbecause of the ease with whichthe height of the apparatus may be adjusted vand becauseof the fact that breakage of glass tubes is practicallyjentirely eliminated.v This support can also be used in the performance of experiments in chemistry wherein a support of this type is desired. i
. It will ofcourse be understood that the 1.99 i
Y side of said body member, the perforations' structure disclosed herein may be departed from without departing from the spirit of my invention as set forth in the appended claims.
Having now described my invention, l claim:
1. A support for laboratory apparatus comprising a flat bar having pairs of braclets or shelves extending from opposite faces thereof, one of said pairs having aligned openings therein for the reception of a vsupporting rod and the other pair having aligned i openings therein for the reception'of tubular apparatus used in performing eXperi- K ments.
2, Apparatus of the character indicated comprising an upright bar havin@ upon one of its faces a pair of brackets perforated for the reception of a supporting rod, and on an other face a pair of shelves provided with aligned openingsfor the reception of apparatus to be used Ain performing experiments, the opening in the lower shelf having a shoulder therein for the support of said apparatus.
3. A support for the purpose indicated comprising a body member having a shelf adjacent one end, said shelf having an Opening therethrough, which opening is of a largflf diameter in that portion which is to be directed upwardly, a second shelf on the bodymember onthesame side as the first shelf and spaced therefrom, said second shelf hav ing an opening therethrough of substantially the same diameter as the larger portion of the opening through the first named shelf, and a pair of perforated brackets on another in said brackets being aligned and adapted to receivea supporting rod whereby the body may be supported for vertical adjustment when in use.
In witness whereof, I hereunto subscribe my name to this specification.
