3 Claims.

The invention here disclosed relates to laboratory frames such as used for the mounting of experimental set-ups and pilot plant apparatus.

Objects of the invention in particular are to provide a universally adaptable form of structure by which the scientist or technician can quickly and easily provide a firm, positive support which can be mounted anywhere, as on the floor, bench, walls or ceiling, of any size or any shape, for any kind of apparatus that he may be called upon to use.

In providing such universal form of frame construction, it is a further purpose to keep the cost at a minimum and to provide the essential parts in simple, rugged, easily assembled and disassembled pieces.

Other important objects are to keep the necessary parts as few in number as possible, and to that end to enable various parts to be used more or less interchangeably to attain different effects.

Further objects of the invention are to provide all necessary strength in as light weight and small compact form as possible.

Objects of the invention also are to provide the various parts in smoothly streamlined formation which in addition to presenting desirable appearance will provide a structure free of sharp edges, corners and projections which might be a hazard, possibly causing accident or injury.

Other desirable objects and the novel features of invention through which all such purposes are attained are set forth or will appear in the course of the following specification.

The drawings accompanying and forming part 1 of the specification illustrate present practical embodiments of the invention but structural features and arrangements may be modified and changed, as will appear from the following specification and claims.

' Figs. 14 and 15 are broken part sectional views of multiple clamp combinations of the invention;

Fig. 16 is a part sectional view of the invention used as a wall clamp; and

Fig. 1'7 is a broken and part sectional view showing the central screw means for securing the elbow of the pivoted clamp appearing in Fig. 4.

Laboratory frames constructed according to this invention are made up of rods of various selected lengths connected together in different angular relations, as required, by means of special mounting and connecting fittings.

' In Fig. 1 one of the rods I0 is disposed vertically' in the form of a post supported by a floor clamp H and carrying, by means of a pivoted clamp 12, a horizontally extending rod l3 and by means of a second, universal clamp [4, a second 'angularly extending rod I 5 and further, by means of an end clamp I6, a. third supporting rod H.

The floor clamp I I is shown as a ring bored to receive the end .of the rod and split at l8 with the split sections secured togetherin clamping n a e en O e the ro b ran fiis screw l9.

Clamps of this type will ordinarily have one or more passages 20 therethrough foranchorage screws 2| which may be engaged in a floor, bench, table, wall, ceiling .or other fixed supporting medium 22, Fig.5.

A feature of this floor clamp and other clamping members to be described is that the passage 23 for the screw in the companion ,split sections intercepts the bore 24 for the rod sufficiently for the screw to enter anannular groove 2,5 in the end portion .of the rod, thusto lrotatably confine the rod in the clamp or, conversely, the clamp on the rod, according .to the particular relation of the rod and clamp.

The end clamp shown at the top of the post at [6 in Fig. 1, embodies the general features of the floor clamp in that it consists of a split ring 26 secured on the rod by clamp screw [9 extending through an annular groove in the rod, but in this case the ring is provided with a screw seat 21 to receive a screw 28 for clamping an end cap 29 over the end of the ring, the cap and ring having companion, substantially

semi-circular seats

30, 3|, in line with or oifset from the bore 24 in the ring to receive and secure a rod such as H at a right angle or other angle to the rod I0.

The pivoted clamp 12 and universal clamp [4 have features of both the floor clamp and end clamp, in the form of annular

split ring members

32, 33, on the pivoted clamp, the split ring member 32 on the universal clamp and end caps 29 being like those used on the end clamp.

The pivoted fixture embodies companion rounded pivoted

members

35, 36, of half the longitudinal cylindrical section of the piece, pivotally connected together in overlying relation by a through clamp screw 31. One of these members, 35, is shown provided with a cylindrical stud extension 38 of the same size and shape as an annularly grooved end portion of one of the rods to fit within and be held in the bore 24 in the split clamp member 32, and the companion member, 36, is shown formed as an integral extension of the split clamp member 33. The latter, like the split clamp 32, has a bore 24 sized to receive a rod end, and in thi particular case adapted to receive the annularly grooved stud extension 39 on the end of the member 40, having a half socket 4la for the rod I 3 which is secured therein by one of the end caps 29.

When this pivoted fitting is clamped in position on the support post 10 by an end ca 29 secured by screw 28 to the split clamp 32, the rod I3 held by the other cap 29 may be pivoted and adjusted in all angular directions to suit any special needs.

The universal clamp I4 is made up by the direct connection of the two

fittings

32 and 40, Fig. 4, omitting the intermediate pivoted connecting

members

35, 36.

In Fig. 3 this is shown accomplished by fastening the member on the upright rod 10 by means of cap 29 and by engaging the split clamp member 32, holding the horizontal rod 15 over the projecting stud 39 of the first member.

The constructions disclosed provide for two and three dimensional adjustments of supporting rods and hence extension and building up of supporting frames in any desired directions and to any required extent. By the use of rods of different lengths these frames may be braced, guided, spaced and supported from a floor, a wall or adjoining or corner walls or from a ceiling or the like, as best suited to existing requirements. The fittings can be quickly and easily applied, removed or adjusted and when set up will hold the parts firmly in position. The frames, made up to required size and shape, instead of being fastened down to a floor or fixed to a wall or other stationary object, may be laid out with extended bases adapted to support the frames upright on a floor, bench, table or other support, free to be moved about, lifted or lowered or inclined, as might be required.

The interchangeability of the rod ends and the projecting studs such as 38 and 39 in the sockets 24 of the split clamps is of great advantage, providing for many structural combinations and relations not otherwise attainable. The split clamps can be engaged over and used in conjunction with either an annularly grooved rod end or the similarly grooved projecting stud of some other clamp fitting and any one of the fittings having such a. projecting stud may be engaged and held in a clamp fitting having a socket for receiving a rod end.

This interchangeability and extensibility of structure is further carried out by the provision of couplings in the form of double or multiple length split clamps, socketed to fit over the rod ends or the equivalent projecting studs.

One of such couplings is illustrated at 4| in Fig. "I, this being a so-called short coupling adapted to be engaged, for example, over the projecting stud 39 of one of the rod clamps 40 to provide at the exposed end of the same a split clamp form of socket 42 for the reception of a rod end or possibly the equivalent projecting stud of some other fitting.

This coupling sleeve is shown split through from end to end at 43 and equipped with

separate clamping screws

44, 45 for the opposite end portions, to enter in the annular grooves 25 as well as to independently apply clamping pressure at the opposite ends of the coupling for securely holding the inserted portions.

Where rods of considerable length are to be joined together, long couplings 50 such as shown in Fig. 6 may be employed, these being of the same design as the shorter couplings but lengthened out to provide a strong joint between adjoining rod sections.

In both forms of the coupling and in general in the split clamps, the cut l8 or 43 forming the split may be extended across the rod receiving socket 24 into the far wall, in the form of a shallow groove 46 to impart a yielding hinged character to the split sections of the member.

While it may ordinarily be desirable to keep the parts locked together in relatively rotatable relation, by engagement of the transversely extending clamping screws I9, 44, 45, in the annular grooves 25 in the rod ends or studs, there may be situations where it would be better to have the parts quickly releasable without having to take the time to remove these holding screws.

This may be accomplished by flattening the ends of the rods or the ends of the studs at one side, into the annular grooves substantially as shown at 41 on the rod [3 in Fig. 1. Then by relatively turning the rod or stud until the flat or relief 41 is lined up with the cross screw such as I!) of the clamp member, the rod may be freely withdrawn from the clamp or the clamp removed from over the rod. This provision is of advantage where it is more essential to have the rods and clamps in quickly connectable and disconnectable relation rather than assure their positive rotatable connection.

To assure firm holding of the clamp screws, lock washers may be used beneath the heads of such screws, as indicated at 48, and the presence or absence of these look washers may be utilized for a further purpose, as brought out in Fig. 4, where the washer has been omitted beneath the head of screw 28 holding the top cap, thus to permit this screw to extend down through the member 40 into a seat 49 in the end face of the swivel clamp 33. In practice there may be a number of such screw end receiving seats 49 in selected angular relations, such as will locate the relatively rotatable stud carrying piece 40 in certain selected angular relations such as to locate the rod [3 carried thereby, for example, at 45 or 90 to the pivot axis 3'! of this fitting.

This feature of providing one member with seats to receive the end of a screw on the companion member, after removal of a locking washer beneath the head of the screw, thus to lock the two members together in certain selected angular relations, may be carried out through all the companion pieces described.

The clamping passages 30 in the end caps 29 are in each instance, Figs. 2, 3 and 4, shown offset to one side of the center line in this and the companion piece to which the cap is secured, thus to provide space and material for the clamping screw 28 at the side of the cap while preserving the external symmetrical dimension of these pieces and keeping them down to a desirable small diameter.

All parts of the frame disclosed are of simple, rugged design and can be produced at reasonably low cost. To avoid rust and corrosion it has been found desirable to make the parts of aluminum alloy and this has the further advantage that it will not disintegrate in the flame of a Bunsen burner, a situation which might occur in the normal use of the frame.

While generally preferred, the rods may be of other than circular cross section and the sockets for the same shaped accordingly. The interlocking of the transverse clamp screws with the annular grooves in the rod ends and studs relatively locates the parts longitudinally. This is an advantage in many cases, for example as shown in Fig. 5, where it may be desirable to keep the end of the supporting rod 10 in the floor clamp off the surface .of the floor or other support 22.

Fig. 8 shows how a coupling 41 or other form of clamp member may be provided with angularly related positioning seats 49 in the end of the same to receive the projecting end of a clamp screw 28 on a member engaged therewith, after the lock washer usually employed with such a screw has been removed. This applied member, as shown in Fig. '7, may be one of the end clamps. The broken lines [1, Ila and I'll: in Fig. 8 indicate the different fixed angular relations of the rod carried by such a clamp with the screw 28 so engaged in different selected recesses 49 in the end face of the companion clamp member.

Figs. 9 and 10 illustrate another form of quick release clamp screw for retaining a coupling or other clamp member on the end of a rod or stud, Fig. 9 howing how with the clamp screw set up tight, the body of the screw will intercept the annular groove 25 in the end portion of the rod or stud to confine the clamp member thereon. Fig. shows how the screw may be backed out a slight distance to bring the annularly grooved portion 52 thereof into line with the groove 25, thus to enable the member being removed from the rod without further loosening or removing the screw.

Fig. 11 illustrates one of the frames made up for mounting on a wall or the like, showing use of the floor clamp II for attaching the frame both to the floor and to an adjoining wall.

Fig. 12 shows how a frame of any size may be made up to stand on a floor or other support and be attached or left free to be moved and shifted about over the floor.

Fig. 13 is a detail showing how a frame can be made up fully supported off the face of a wall, using floor clamps ll secured directly on the ends of the horizontal wall supporting'rods l0 and floor clamps H engaged over the stud ends of pivoted clamps I2 on the upwardly inclined bracing rods 10.

Figs. 14 and 15 illustrate multiple clamp constructions for securing three rods in various angular relations and including the split clamp 32 to receive and secure the end of one rod, the one at the right in Figure 14, and cross grooved at the opposite face at 53 to accommodate the second, upright rod held thereto by one of the members 40 having the projecting stud 39 secured in the second split clamp 32, which holds the third horizontal rod, at the left, by the end cap 29.

The vertical rod ID in Fig. 14 is held clamped between the seat Ma in the end of member 40 and seat 53 in the end of split clamp 32, by a screw connecting these parts which does not appear in this figure but which i shown at 28 in the complementary view, Fig. 15.

Where the three rods are in parallel planes, with no end rod connection, the combination may be made up as in Fig. 15 with a stud fitting 49 added to the clamp fitting 32 in place of the horizontal rod shown at the right in Fig. 14 and having an end cap 29 applied thereto for securing the third parallel related rod [0.

A wall clamp for holding a rod parallel to a supporting wall may be made up as shown in Fig. 16, with one of the stud fittings 40 carrying the rod and engaged with the wall or floor clamp ll screwed fast to the wall or supporting structure 54.

The pivoted clam 12 shown in Figs. 1 and 4 may have a screw 55 extending inwardly through the stud 38 of the member 35 into engagement with positioning seats 56 in the end of the companion member 36, to enable quick and secure fastening of these two pivoted members in definitely determined selected angular relations.
