Aug. 25', 1953 J. s. KESSLER ToGGLE TYPE CONNECTING ASSEMBLY' Filed Jan. 20, 1951 JNVENTOR. (y/4 '/7/ Afina/VIVAS'.

Patented Aug. 25,v 1953 2,649,632 TQGGLE QQNNECTING ASSEMBLY Joseph Kessler, Kenosha, Wis., assigner to Trirloyer Machine Q9., Kenosha; Wis.; a -corporaliieg ,sessie malienne Jaeger 1951; .Segal Nw $06,947

This invention relates to improvements `in .toggle type connecting assemblies, .and more partie.- ularly to connecting assembliesfor 'drawing and holding together the ends .of a .clamping band.

In industries, such as theafood'ind'ustry, wherein it is of utmost importance that sanitary condi.- tions at all times prevail,- the equipment .used therein must be frequently ,disassembled and cleaned. To .this endlthe equipment imnst he Aolesigned with a minimum .of parts, said parts be.- ing associated in easily .disassembled relationship and being devoid, as much .as nossiblepf screw threading, corners, .or .othercrevices .Where .QQQ- particles may lodge.

Because it is particularly vielladapted fornelli.- tary applicationsthe gvetypelampinghalll, used in connection with langedfiuplnlg replaced bolted typeomiection.at ,many points in food handling equipment. While certain of the V-type clamping bands heretofore available have been provided with toggle type .connecting assemblies, these .connecting Aassemblies have not been entirely satisfactory because, as 'heretofore constructed, disassembly and cleaning have been difcult and time consuming.

It is, therefore, va generalplqjectpf the present invention to provide an vimproved toggle type connecting assembly which is ladapted for use on V-type clamping bands as vvellv as in `othergapplications, said assembly Y,being so constructed i that it may be quickly, easily, and completely' disassembled.

A further object of the present invention is to provide an improved connecting assembly of the class described wherein the individual parts are substantially devoid of corners or crevices which might cause lodgement of food particles.

A further object of the invention is to provide an improved toggle type connecting assembly for a device which has a pair of relatively movable end portions which are to be drawn together wherein there is a novel coaction between the nose of the toggle handle and a lug on one of the end portions.

A further more specific object of the invention is to provide an improved toggle type connecting assembly for V-type clamping bands, said assembly having a bail connected to one end of the band and having a locking handle pivotally connected to said bail and engageable with the other end of said band but not positively connected therewith.

A further object of the invention is to provide an improved connecting asesmbly of the class described which is simple in construction, inexpensive to manufacture, and otherwise Well adapted for the purposes described.

With the above and other objects in view, the invention consists of the improved toggle-type connecting assembly, and all of its parts and combinations, as set forth in the claims, and all equivalents thereof.

In the drawing accompanying and forming a part of this specification, wherein is shown one complete embodiment of the preferred forni of the invention and wherein likeV characters of reference indicate the same parts inall of the views:

Fig. l is a side elevational view of the improved connecting assembly applied to a V-type clamping band .and disposed in locked position;

Fig. 2 is a plan view of the clamping band and connecting assembly shown in Fig. l;

Fig. 3 is a fragmentary vertical sectional view .taken approximately along vthe line -3-3 of Fig. 2; .and

Fig. ki is ,a fragmentary transverse sectional View taken along the line {l-Il of Fig. 1.

Referring more particularly to the drawing, the numeral 5 indicates a conventional Vftype clamping band `which is preferably circular in outline. The band i5 is formed with a cylindrical peripheral `,wall portion .t (see Fig. 4), having divergent inwardly extending annular wall portions and yil, said Wall portions at their inner edges being formed with oppositely projecting annular flanges Sand f respectively. Theband is formedwth`v a pair of juxtaposed opposite end portions I I and I2. Diametrically opposite the end portions II and I2, a portion of the walls 'I and and flanges 9 and I0 is cut away as at I3 to leave an extent of the Wall 6 which is ilexible.

Mounted on the end portions II and I2 respectively is a pair of lugs I4 and I5 which form a part of the improved connecting assembly. The lugs I4 and I5 are formed with lips Iii and I1 respectively which lips project in opposite directions in the plane of the band 5, the lugs being formed beneath said lips with transversely extending rounded grooves I8 and I9. ,f

A locking handle 20 of irregular conformation is channel shaped in cross-section for the major portion of its length, and has a width greater than the width of the lug I5 and lip II, as shown in Fig. 2. The handle 2n is formed at one end with a rounded nose portion 2l which is adapted to be pivotally seated in the transverse groove I9 of the lug I5, as shown. The handleidi is formed in a portion of its web which is adjacent its nose 2I with an aperture 22, said aperture being so positioned and of such size as to receive the lip I1 as the handle 2U is swung outwardly about its nose when the latter is seated in the groove I9.

Spaced inwardly from the nose portion 2I the handle 2li is formed in its opposite side flanges with a pair of aligned apertures '23 and 24. An elongated, generally C-shaped bail 25 has a pair of inwardly directed end portions 26 and 21 which project inwardly through the apertures 24 and 23 respectively. The bail 25 also has a closed loop portion 28 opposite the end portions 26 and 21, the portion 28 being seated in the transverse groove I8 of the lug I4 below the lip I6 thereof.

The lug I4 is formed with'a vertical bore 29" spaced inwardly from the lip I6, which is adapted to removably yet snugly receive a retaining pin 30. The bore 29 and pin 35 are positioned to prevent removal of the bail 25 from the lugV I4.. The end portions 26 and 21 of the bail 25 are cut away as at 3l (see Figs. 2 and 3) `to receive the side ange portions of the handle 20 adjacent margins of the apertures through which said bail ends project. The handle 2B may be formed with an enlarged aperture 32 in the web portion thereof adjacent the apertures 2; and 24, as shown.

When in locking position the handle 25 normally lies against the band 5. In this position the end portions H and I2 of the band 5 are rigidly held in relatively close relationship. To loosen the band 5 it is only necessary to swing the free end of the handle 2 outwardly away from the g# band 5, thereby pivoting the handle about its nose 2|, the latter being seated in the transverse groove I9. This swings the end portions 215 and 21 of the bail upwardly and moves said bail toward the lug I4, thereby permitting lugs Ill and I5 and end portions II and i2 to move apart. As the handle 20 is swung in this manner, the lip l1 is received in the handle aperture 22. The handle 29Ycan be thereafter readily swung out of engagement with the lug I5 and lip I1. As the band 5 is removed from its operative position, one end of the bail 25 remains connected to the handle 2Q while the other end remains connected to the lug I4 because of the retaining pin 30.

The handle 20 can be readily removed the bail 25 by spreading apart the end portions 26 and 21 to remove the same from the apertures '23 and 24. Removal of the bail 25 from the lug I4 can be readily eiected by removal of the pin 38. The completely disassembled parts can then be easily and quickly cleaned. Reassembly of the 4 parts is accomplished by a reversal of the operation just described.

Various changes and modifications may be made without departing from the spirit of the invention, and all of such changes are contemplated, as may come within the scope of the claims.

What I claim is: Y
