DISPENSER WITH CARTRIDGE ALIGNING MEANS Filed June 9, 1966 2 SheetsSheet 2 INVENTORS.

United States Patent M 3,369,714 DISPENSER WITH CARTRIDGE ALIGNING MEANS Vincent E. Dewees, J enkintown, and William T. Reynolds,

Dresher, P2,, assignors to Kenmar Manufacturing Company, Philadelphia, Pa., 2 copartnership Filed June 9, 1966, Ser. No. 556,405 2 Claims. (Cl. 222-327) ABSTRACT OF THE DISCLOSURE Dispensers for materials in drop-in cartridges with or Without attached spouts in which the cartridge is retained in optimum alignment, by being held at the rear end during dispensing, cartridges without spouts being accommodated by an adapter providing a dispensing member which holds the front end of the cartridge centered and against rupture and carries a dispensing spout.

This invention relates to dispensers for mastic materials such as sealants, adhesives, caulking materials, grease and the like.

It has heretofore been proposed to provide dispensers for mastic materials distributed in cartridges, which cartridges in some instances have spouts, or nozzles and in others have removable end closures, and which cartridges are adapted to be dropped into position for use.

The dispensers of the cartridge drop-in type heretofore available did not retain the rear end of the cartridge against displacement. The attendant misalignment of the cartridge in the dispenser caused leakage at the piston or even rupture of the cartridge.

It is the principal object of the present invention to provide a dispenser for use with cartridges either with or without spouts or nozzles carried directly on the delivery end of the cartridge and in which the cartridge is held at the rear end in an improved manner.

It is a further object of the present invention to provide a dispenser for use with drop-in mastic containing cartridges which cartridges can be spout carrying cartridges, an adapter being provided for use with standard nozzles.

It is a further object of the present invention to provide a dispenser for use with drop-in mastic containing cartridges which is particularly useful for relatively longer and/or larger cartridges than the dispensers heretofore available.

Other objects and advantageous features will be apparent from the description and claims.

The nature and characteristic features of the invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part thereof, in which:

FIGURE 1 is a view in perspective of a dispenser in accordance with the invention employing a spouted cartridge,

FIG. 2 is a longitudinal sectional view taken approximately on the line 2-2 of FIG. 1;

FIG. 3 is a transverse vertical sectional view taken approximately on the line 33 of FIG. 2;

FIG. 4 is a fragmentary longitudinal sectional view showing the details of the spout;

FIG. 5 is a view in perspective of the front end of the dispenser of the present invention with the adapter for a spoutless cartridge in place;

FIG. 6 is a fragmentary longitudinal sectional View, enlarged, taken approximately on the line 66 of FIG. 5;

FIG. 7 is a transverse sectional view taken approximately on the line 7-7 of FIG. 6; and I FIG. 8 is a fragmentary longitudinal sectional view 3,369,714 Patented Feb. 20, 1968 of a cartridge having a removable end closure and which is shown in FIG. 6 in condition for use.

It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes can be made in the structure disclosed without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring first to FIGS. 1 to 4, inclusive, the cartridge C1 there shown is of well known disposable type with a hollow cylindrical Wall 10 with a smooth interior surface and of a spiral wound tube of paper, paper board or the like. The wall 10 has a front end cap 11 of metal secured thereto and carrying a spout 12, preferably of flexible synthetic plastic material with a tapered closed end 13. The end 13 can be cut with a knife (not shown) at the desired distance along the tapered end 13 and at the desired angle in accordance with the dispensing opening 14 which is desired. At the opposite end of the wall 10 an interior cup-shaped piston 15 provides a closure.

Referring now to FIGS. 6 and 8 the cartridge C2 there shown is also of well known disposable type with a wall 10 as before and an end cap 16 with a removable closure 17 normally frictionally held in position in a frustoconical ring 18 on the end cap 16. The opposite end of the wall 10 has apiston 15 as before.

Referring now to FIGS. 1, 2 and 3, the dispenser preferably includes an elongated trough shaped magazine 20 with a flanged end stop 21 secured thereto in any desired manner at one end and with a forwardly flanged end receiver 22 at the other end. The end receiver 22 has a forwardly extending flange 22a and at the rear has a fixed handle 23 secured thereto with side frame portions 24 which carry a pivotally mounted spring urged handle 25 on a pin 26 which through a pivotally mounted spring ratchet 27 on the handle 25 engages a piston rod 28 shown as notched as at 29. The piston rod 28 has a piston plate 30 at one end thereof, for engagement in the piston 15, and a handle rod 31 at the other end for drawing the rod 28 backwards if desired, or for turning the rod 28, if desired, for release.

A spring urged pivotally mounted ratchet 32 supported on a pin 33 by the side frame portions 24 prevents the undesired return of the rod 28.

The mechanism just described for actuating the piston rod 28 is of well known type and any other actuating mechanism can be employed if desired.

In accordance with the present invention the end stop 21 has a radially extending slot 35 with a forwardly extending internally threaded collar 36 with a slot opening 37 the slot 37 being smaller in its transverse dimension than the internal diameter of the collar 36 to provide a holding action.

With the piston rod 28 at its rearmost position the slot 35 and collar 36 permit of the insertion of the spout 12 with the end cap 11 within the flanged end stop 21.

In accordance with the present invention the end receiver 22 has the flange 22a thereof extended forwardly so that when the cart-ridge C1 is seated as shown in FIGS. 1 and 2 the flange 22a overlaps the rear end of the cartridge C1 about three quarters of an inch to prevent its displacement as the piston rod 28 is advanced with the piston plate 30 engaged within the piston 15. Before the piston rod 28 is advanced by actuation of the movable handle 25 to a point to apply pressure to the piston 15 the spout 12 is cut to provide the desired dispensing opening 14.

The structure as heretofore described is suitable for dispensing from spouted cartridges C1 with the cartridge C1 retained in the magazine 20 during the entire advancing movement of the piston 15.

Upon completion of the dispensing or exhaustion of the contents of the cartridge C1 the piston rod 28 is released as by turning the notches 29 to an inactive location, and the piston rod 28 is manually withdrawn to its rearmost positron.

The cartridge C1 can then be removed and a new cartridge C1 inserted as before.

If it is desired to employ a cartridge C2 as shown in FIG. 8, an adapter is utilized.

Referring now to FIGS. 5 t 8, inclusive, a sleeve 40 is provided having an exterior threaded portion 41 en gageable in the threaded collar 36. The sleeve 40 has a knurled portion 42 beyond the threaded portion 41 for manual engagement to facilitate insertion of the sleeve 40 in the collar 36.

The sleeve 40 has a central passageway 44 threaded as at 45 at its outer end for carrying a nozzle 46 of conventional type. The sleeve 40 at the other end of the passageway is flared as at 47 for reception of the ring 18.

An end abutment plate 50 is provided having an interior threaded opening 51 with the threads tapered like pipe threads to limit the movement of the plate to a position where its rear face 52 is flush with the rear end of the sleeve 46. The assembly of plate 50, sleeve 40 and nozzle 46 can, by turning of the sleeve 40 be positioned along the collar 36. For initial insertion of a cartridge C2 after removal of the closure 17, the abutment plate 50 is moved forwardly to the extent required to permit dropping the cartridge C2 into the magazine and then the assembly of plate 50, sleeve and nozzle 46 is moved rearwardly by turning the sleeve 49 until the rear face 52 of the plate engages the end cap 16. The plate 50 is of a size so that it covers a substantial portion of the area of the forward end of the cartridge, thus transferring the thrust of the cartridge to the front of the dispenser without danger of distortion or puncturing the end cap 16. The edges of this plate fit closely within the recess formed by the flange of cap 16 which joins the ends of wall 10, thus ensuring proper radial and axial alignment of the cartridge. The ring 17 then engages in the flared passageway 47 and the dispenser is ready for use.

Actuation of the advancing mechanism from the piston rod 28 is effective for moving the piston plate 30 to impel the piston 15.

The cartridge C2 can be removed by a reversal of the operations previously described.

We claim:

1. In a dispenser having a trough shaped magazine for the insertion of disposable cartridge, said magazine having a rigidly connected front end wall with a slot at its front end providing an end stop and a rigidly connected cartridge end receiver having a rear end wall with piston rod actuating means at its rear end, the improvement which comprises for cartridges of shorter length than the distance between said end Walls,

means for retaining the front end of the cartridge against displacement from a predetermined axial and radial position, said means including a collar on said end stop, and a dispensing member engaged with said cartridge and with said collar, said dispensing member including an externally threaded portion engaging said collar and an abutment plate carried by said threaded portion, said abutment plate having a flat rear face with which the forward end of the cartridge is in thrust transferring engagement over a substantial portion of the area of said forward end, the edges of said plate having means to engage the periphery of said end to align said cartridge, means for retaining the rear end of the cartridge against axial misalignment when said front end of said cart-ridge is retained by said front end retaining means, said last means having a forwardly extending flange surrounding the rear end of the cartridge upon forward movement of said piston rod. 2. A dispenser as defined in claim 1 in which said abutment plate has an internally threaded portion in engagement with said externally threaded portion, the threaded portion of said plate has the threads thereof shaped to limit the movement of the abutment plate with respect to the externally threaded portion thereby to position the rear face of the abutment plate at the end of said externally threaded portion.
