ANALYSIS INSTRUMENT MOUNT FOR AXIALLY PARALLEL CYLINDERS The invention relates to a receptacle or mount for axially parallel parts, usually cylindrical units used in optical instruments for the analysis of fluids.
In order to avoid complicated justification procedures, in the past, the units, which also must be easily interchangeable, have been disposed on especially profiled rails so that upon the units being laid on the rails, the units assume the correct axial positions relative to one another. However, additional fastening devices at the rails were provided for securing the units in position. The units can also be designed to be coupled with each other so that one or two testing devices are sufficient.
Heretofore the profiled rails, which were still to be mounted on a base plate, required a considerable amount of work in their production. The expense of making a mount or receptacle for the units was far out of proportion to the simple object of the receptical, the simple function of receiving the units and positioning them.
The present invention provides an extremely simply and inexpensive cheap receptacle for analysis instruments units that must be axially parallel. By using plate material which is also suitable for the base in the prior art, the material is displaced to form a lengthy depression extending along straight lines, which depression serves as a bed for the units. Preferably the depression is formed from two separated long inwardly directed equally downbent side flanges on the interior of the plate. If the free edges of the side flanges are parallel to the general plane of the plate then units, provided with fastening bolts extending through the resulting slit between the edges, can be easily and adequately secured on the plate in screw fashion.
DRAWING FIG. 1 is a plan of the receptacle with units fastened thereon, and i FIG. 2 is a cross sectional view of the receptacle, the section being taken substantially along the line 2-2 of FIG. 1 and looking in the direction of the arrows of said line.
DESCRIPTION OF PREFERRED EMBODIMENTS The mounting receptacle shown is formed from a rectangular plate 1 of, say, thick sheet aluminum having a medial longitudinal slit 2 between two transverse end slots 3 and 4 in the end portions of the plates so as to form two opposite and inwardly directed sheet metal flanges 5 and 6, or tongues much wider than their lengths, which are offset or downwardly bent at equal angles and preferably along parallel lines, and so form a depression or crevasse.
Cylindrical units 7, 8, 9 and for an analysis instrument, such as an instrument operating byradiation absorption are disposed axially parallel in the depression. If the flanges are bent along parallel lines the cylindrical units will automatically lie axially parallel. The units may be for varied specific purposes. For example, unit 7 may be for a source of radiation, unit 8 a container for a filtering medium, unit 9 for containing a fluid to be analyzed and unit 10 a sensor for the radiation passing through units 8 and 9. The unit 10 may provide the radiation and unit 7 be the sensor.
The edges 11 and 12 of the respective flanges are aligned parallel to the plate 1, the clearance between the two edges 11 and 12 of the flanges being sufficient to accomodate guide bolts and mOunting studs 13 for securing some of the units to the receptacle. The mounting stud 13 may be fast on its unit at the peripheral surface of the latter and provided with a threaded pin or stud bolt 14 passing between the edges 11 and 12 and on which is a nut 15 for bolting the respective units on the receptacle. The edges 11 and 12, or rather the flange marginal portions adjacent the edges, are
- offset extending again parallel to plate 1 so that a sufficient contact surface is provided for the nut 15, and hence the cylindrical units are securely clamped in and to the receptacle in axis parallel relation (or coaxial as a special case).
Unlike units 7, 8 and 9, unit 10 is fixed in the receptacle by means of screws 16 and 17 passing through the flanges l1 and 12. If, as here assumed, the units can be coupled directly to one another as for example by a bayonet connection, it is sufficient to fix only two units in the receptacle. However each unit may be fixed in the receptacle by itself and with distance between the adjacent units by means of the fastenings if provided for each movable unit.
The units need not be cylindrical. They can be outfitted with contact devices for electrical connectors and other auxilliary devices so long as they do not interfere with the units lying axially parallel in the depression.
The invention claimed is:
1. In an analysis instrument which includes a plurality of cylindrical objects to be mounted in axis parallel relation, the combination comprising:
a mounting plate having an opening, a pair of straight flanges having edges facing each other across a slot, the flanges extending at similar angles from the plate and below the plate, the flanges forming a longitudinal crevasse having straight-line juncture with the plate at opposite sides of the opening, substantially at the plane of the plate and integral therewith to form a depressed bed;
cylindrical instrument construction units disposed in the bed coaxially to each other, having diameter 1 significantly larger than the width of said slot, and resting on the flanges in tangential engagement therewith; and fastening means for the units for fastening them to the flanges and including a fastener for at least one unit, tightening the unit against the flanges from below by engaging the edges and traversing the slot for being secured to the unit in the bed. 2. In an instrument as claimed in'claim 1, the edges of the flanges at the slit being parallel to plane of the plate.
