D. LA MAR Aug. 21, 1956 TONGUE AND SLOT JOINT CONSTRUCTION FOR FILLING MACHINES Filed Dec. 25, 1950 Y' United States Patent() TONGUE AND SLOT JOINT CONSTRUCTION FOR FILLING MACHINES Delbert La Mar, Hoopeston, Ill., assignor to Food Machinery and Chemical Corporation, San Jose, Calif., a corporation of Delaware Application December 23, 1950, Serial No. 202,519
3 Claims. (Cl. 287-101) The present invention relates to a tongue and slot joint construction.
One object of the present invention is to provide a tongue and slot joint which may be easily and quickly coupled and uncoupled.
Another object of the present invention is to provide an improved, inexpensive, tongue and slot joint which permits pivotal motion of the joined parts in one direction and is substantially rigid in all other directions.
Another object of the present invention is to provide a tongue and slot joint which cannot become uncoupled during the operation of the connected parts.
Another object is to provide a tongue and slot joint which will compensate for misalignments between relatively moveable parts, thereby eliminating the time, labor, and cost of making and assembling parts so that they will be exactly in line.
A further object is to provide a tongue and slot joint that substantially prevents longitudinal motion between connected parts but which permits relative tilting of the joined parts.
These and other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings wherein:
Figure l is a Vertical section of a portion of a plungertype iilling machine showing one use of the tongue and slot joint of the present invention.
Figure 2 is an enlarged vertical section of the tongue and slot joint of the present invention with certain parts shown in elevation.
Figure 3 is a reduced section taken along the line 3--3 of Figure 2, certain parts being shown in elevation.
Figure 4 is a perspective view of one of the members of the tongue and slot joint of the present invention.
The tongue and slot joint of the present invention, shown in Fig. l, is illustrated as embodied Vin a plungertype iilling machine provided with a circular container path. This type of lling machine used for iilling food products, such as baby food, into containers is well known in the art, and only the portions of the complete filling machine necessary for a complete understanding of the present invention have been illustrated. The lling machine comprises a rotatable, turret 9, partially shown in Fig. l, which is provided with a plurality of vertical guide ways 10, only one being shown. Slidably mounted in each guide way is a guide block 11 of a piston assembly unit 12. The guide block 11 is provided with a stub shaft 13 on which a roller 14 is journaled. The roller 14 is adapted to ride in an annular stationary hill and dale cam track 16 which encircles the turret 9, whereby the guide block 11 is supported for vertical reciprocation in the guide way associated therewith.
Each guide block 11 is formed with a slot 17 in which a bracket 18 is held for both vertical and horizontal adjustment by means of cap screws 19 and enlarged holes 20 formed in the bracket 18. The bracket 18 has an enlarged head 21 to which one member 22 of a tongue and slot joint 23 is secured. The member 22 has a stud 24 Patented Aug. 21, 1956 ICC extending therefrom which is retained in a hole 24a, provided in the head 21, by a tapered pin 25, thereby rmly attaching the member 22 to the head 21. Mated with the joint member 22 is a similarly configured tongue and slot joint member 26 provided with a threaded connecting rod 27. The connecting rod 27 is threadably engaged with an internally threaded portion 28 formed on the socket member 29 of a ball and socket joint 30. A lock nut 31 mounted on the connecting rod 27 and threaded tightly against the internally threaded portion 28 prevents relative movement between said connecting rod 27 and the socket member 29. Loosely mounted on the connecting rod 27 is a sleeve 32 for retaining members 22 and 26 in mated relationship. The sleeve 32 is constantly urged downwardly around the engaged members 22 and 26 and against the head 21 by a spring 33 mounted on the connecting rod 27 between the lock nut 31 and the sleeve 32.
The ball and socket joint 30 is attached to a piston 34 by means of a wrist pin 35, that has a ball 36 of the joint 30 mounted thereon and which is journaled in diametrically opposed holes 37 provided in the wall of the piston 34. The piston 34 is adapted to reciprocate vertically within a cylinder 38 secured to the turret 9, by means not shown. When the connected turret 9 and cylinder 38 are rotated, by means not shown, the piston assembly unit 12, will rotate with them and will be caused to reciprocate vertically due to the hill and dale configuration of the annular stationary cam 16.
The tongue and slot joint member 26 (Figs. 2 and 3) is generally cylindrical in shape and the tongue and slot joint member 22 (Figs. 2, 3 and 4) is generally barrel-shaped being tapered toward both its ends. The member 22 comprises a base portion 40 from one side of which extends upwardly a hooked or L-shaped tongue 41 which, in conjunction with the base portion 40, defines a straight-sided slot 42 for the reception of another hooked or L-shaped tongue 45, similar to the tongue 41, that depends from a base portion 46 of the joint member 26. The depending tongue 45 defines in conjunction with the base portion 46 a straight-sided slot 47 which is adapted to receive the tongue 41. This engagement of the tongues 41 and 45 in the slots 47 and 42, respectively, may be quickly and easily accomplished and makes possible the insertion and removal of the piston 34 (Fig. l) from the cylinder 38 without the necessity of dismantling the entire piston assembly unit 12.
The tongues 41 and 45 (Figs. 2, 3 and 4) have narrow elongated ilat surfaces 49 and Si) on their free ends, which surfaces, when the members 22 and 26 are engaged, are normally parallel to and slightly spaced from inner surfaces 51 and 52, of the members 26 and 22, respectively, as shown at 54 and 55 in Fig. 2. These spaces 54 and 55 between the engaged parts 22 and 26 are so small that there is substantially no longitudinal play or movement between the tongue and slot members 22 and 26. Moreover, since the opposed surfaces 5u and 52 and the corresponding opposed surfaces 49 and 51 are closely spaced, parallel and of considerable relative length (Fig. 3) there is substantially no transverse or to-and-fro, rocking or tilting movement between the engaged members 22 and 26 in the directions of double arrows a.
Adjoining the' surfaces 49 `and 5t) (Figs. 2, 3 and 4), the free ends of the tongues 41 and 45 are cut away forming inclined at surfaces 57 and 58 and provided enlarged spaces 57a and 58a, respectively, between the members 22 and 26 when they are engaged. Because of the spaces or clearances 54 and 55 between the mated parts 22 and 26, the enlarged spaces 57a and 58a between the surfaces 51 and 57, and the surfaces 52 and 58, respectively, and the relatively small width of the surfaces 49 and 50, the tongue and slot members 22 and 26 are adapted tomate readily with each other and to tilt or pivot laterally in the directions of double arrows b (Fig. 2) when engaged. Should there be any lateral misalignment of the cylinder 38- and the bracket 18, thisA lateral pivotal action of the member 26- willcompensate therefore by allowing the connecting rod' 27 to tilt laterally so that the piston: 34 (Fig. l) may align itself with the cylinder 38 and reciprocate smoothly therein. Any other misalignment of the cylinder 38 and the bracket 1.8 may be corrected by adjustment of the bracket 13 in the slot 17, as previously described.
The piston 34 is quickly disposed in operative position in the cylinder 38 by first introducing the piston 34, with the connecting rod 27 attached and depending therefrom, into the cylinder 38 at its upper end'. The sleeve 32 is then raised against the tension of the spring 33, the menr bers 22 and 26 engaged, and thel sleeve 32 released whereupon the spring 33 will urge the sleeve 32 down upon the bracket head 21, thus preventing disengagement of the members 22 and: 26 during the operation of the joint 23. The tongues 41 land 45 will mate easily with their respective slots 47 and. 42 since the closely spaced tongue end surfaces 49 and 50 are relatively small in width (Figs. 2 and 4) and have abutting them the inclined fiat surfaces 57 and 58, thus allowing the members 22 and 26 to mate although they may be disposed `at a slight angle with each otherr Since the sleeve 32 ismounted on the connecting rod 2.7, it will tilt with said connecting rod 27 and will ride or cam' on the curved substantially barrel-shaped sides of the member 22 when the joint 23 is tilted. Therefore the sleeve 32 will not interfere with the aligning action of the joint 23 although the clearance between the sleeve 32 and the member 22 may be relatively small,
While I have described a preferred embodiment of the present invention it will be understood, however, that various changes and modifications may be made in the details thereof without departing from the spirit and the scope of the appended claims.
Having thus described the invention what I claim as new and desire to protect by Letters Patent is:
