CLAMP FOR CHEMICAL APPARATUS W FIG. 1.
Filed March 8, 1950 FIG. 6.
INVENTORSI FREDDIE Y B. RICHARDS ROGER W. MCBRIEN ATTORNEY.
Patented Nov. 2, 1954 CLAMP FCR CHEMICAL APPARATUS Freddie B. Richards and Roger W. McBrien, Alton, Ill.
Application March 8, 1950, Serial No. 148,354
3 Claims. (Cl. 24243) Our invention has relation to clamps for supporting chemlcal apparatus and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims. The object of the invention is to provide a clamp that is universal in its application to apparatus in that it may be readily adjusted to fit apparatus of widely varying sizes. A further object of the invention is to provide an adjustable or universal clamp that is simple and that may be readily adapted to apparatus of dilferent sizes and that, at the same time, is positive in its operation. These advantages will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which:
Figure 1 is a side elevation showing my improved clamp supported by a suitable stand and holding a test tube in position; Figure 2 is a horizontal section taken on the line 2, 2 of Figure 1; Figure 3 is a vertical section taken on the line 3, 3 of Figure 2; Figure 4 is a horizontal section taken on a plane indicated by the line 4, 4 in Figure 3; and Figure 5 is a cross sectional detail taken on the line 5, 5 of Figure 3.
Referring to the drawings, B represents a base having a. standard 1 to which is clamped, by a clamp member 2, a horizontally disposed tube 3. The tube 3 has a plate 4 fixed to one end thereof and the plate has a pair of arcuate members 5, 5 secured to it in spaced relation.
The members 5, 5 are covered with short sections of rubber tubing 6, 6 to furnish a seat against which a test tube T (or equivalent chemical apparatus) may rest. The test tube T is held in intimate relation with the supporting seats 6, 6 by a band 7 formed of fiat wire, said band being securely held in any one of a plurality of slots 8, 8 etc. formed in a bar 9 disposed within the tube 3. At the outer end of the bar 9 is a stem having a polygonal portion 10 and a threaded extremity 11, the polygonal portion passing through a similarly shaped opening 12 at the end of the tube 3, and the threaded portion receiving a nut 13 whereby the bar 9 may be withdrawn from the tube so as to take up whatever slack may exist in the band 7, so as to hold the tube tighter within said band.
Obviously, the band 7 is of such length that when inserted within the tube 3 it may be disposed in any one of the slots 8 depending upon the size or" the tube T that is to be encompassed.
From the foregoing it is apparent that We have provided a clamping device that is applicable to a large number of sizes of chemical apparatus and that may be quickly and effectively applied thereto.
In Figure 1 We show a Bunsen burner B merely to indicate one of the applications of the invention.
Having described our invention, we claim:
1. A clamping device comprising, a tubular member, said tubular member carrying a seat at one end, a bar having a plurality of kerfs within said tubular member, means for moving said bar longitudinally therein and a band cooperating with said seat to serve as a clamp for chemical apparatus, said band having its ends disposed in one of the kerfs of the aforesaid bar.
2. A clamping device comprising, a tubular member, said tubular member carrying a seat at one end, a bar within said tubular member and having a plurality of kerfs spaced apart longitudinally of the bar, means for moving said bar longitudinally therein and a band cooperating with said seat to serve as a clamp for chemical apparatus, said band having its end portions juxtaposed and oifset laterally of the bar and disposed in one of the kerfs of the aforesaid bar, said seat comprising a plate and bearing members carried thereby.
3. A clamping device comprising, a tubular member, said tubular member carrying a seat at one end, a bar Within said tubular member and having a plurality of kerfs at intervals lengthwise of the bar, means for moving said bar longitudinally therein and a band cooperating with said seat to serve as a clamp for chemical apparatus, said band being disposed in one of said kerfs.
