DISPENSING DEVICE WITH REPLACEABLE CARTRIDGE Filed Feb. 26, 1962 INVENTORS VINCE/VT E. DEWEES BY 650065 A. PEER/5 ATTORNEY United States Patent 3,121,516 DISPENSING DEVICE WITH REPLACEABLE CARTRIDGE Vincent E. Dewees, .lenkintown, and George A. Ferris,
Philadelphia, Pa, assignors to Kenmar Manufacturing Company, Philadelphia, Pa, a copartnership Filed Feb. 26, 1962, Ser. No. 175,470 2 Claims. (Cl. 222-326) This invention relates to dispensing devices with replaceable cartridges containing the material to be dispensed.
It has heretofore been proposed to provide dispensing devices with replaceable cartridges. Most of these have had a frame extending forwardly from the operating head in which the piston rod and rod actuating structure is mounted with the dispensing end of the cartridge held at the front end of the frame, the rear end of the cartridge being held by the frame and also by the advancing piston and piston rod. The removal and insertion of the cartridge involved difiicnlties in manipulation with possibility of misalignment of the rear end of the cartridge and difliculties in insertion of the piston into the rear end of the cartridge.
It is the principal object of the present invention to provide a piston and cartridge type of dispensing device in which the cartridge is held entirely at the rear end and at the same time is readily insertable and removable.
It is a further object of the present invention to provide a piston and cartridge type of dispensing device in which the cartridge has an end rim with simple but eifective structure on the head for receiving and retaining the cartridge end rim.
It is a further object of the present invention to provide a piston and cartridge type of dispensing device in which the cartridge has an end rim with simple but effective structure [for receiving and releasably holding the cartridge end rim.
it is a :further object of the present invention to provide a piston and cartridge type dispensing device in which a rotatable element is provided for facilitating the insertion of the cartridge rim for retention and for permitting removal of the cartridge when desired.
Other objects and advantageous features of the inven tion 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 perspective view of a dispensing device in accordance with the present invention;
FIG. 2 is a vertical longitudinal sectional view taken approximately on the line =2-2 of FIG. 1;
FIG. 3 is a transverse sectional view taken approximately on the line 3-3 of FIG. 2;
FIG. 4 is a fragmentary sectional view showing the gripping of the rear end of the cartridge; and
FIG. 5 is a fragmentary sectional view similar to FIG. 4 but showing the rear end of the cartridge in spaced relation to its seat as upon insertion or removal.
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 now more particularly to the drawings, the dispensing device preferably includes a head frame which can be of well known type made of sheet metal with a fixed handle 11, and with an end housing 12 secured thereto.
The :head frame 14 and end housing 12 can have aligned openings 13 and '14 for the reception of a rotatable and axially movable piston rod .15. The piston rod 15 has a piston #16 at the front end, a rear bent end 17 and intermediate its ends ratchet teeth 18.
A movable trigger 19 can be provided pivotally mounted in the frame 10 on a pivot pin 20, with a ratchet 21 urged by a spring 22 into engagement with the ratchet teeth 21 when the piston rod 15 is oriented for this purpose. An abutment 23 for the spring 22 can be provided in the trigger 19. A retaining ratchet 24, urged by a spring 25 and carried on a pivot pin 26 in the frame 10*, prevents retrogress-ion of the piston rod 15. A stop pin 27 in the frame 10 serves as an abutment for the spring 25 and as a stop for limiting forward movement of the trigger 19.
The structure just described is known in the art, and the invention hereinafter to be described is particularly suitable for but is not limited to use therewith.
In accordance with the invention a cartridge 30 for the material to be dispensed is provided and is of a flexible material, such as polyethylene or the like. The cartridge 30, if prefilled, can have a closure plug 29 therein. The cartridge 3% has a tubular body 31 and at the front or free end thereof can be provided with any desired type of discharge control device 32 which can be a nozzle or the like integral with the body 31. The body 31, at the rear end thereof is provided with a rim 33 projecting outwardly a distance of the order of the thickness of the cartridge body 3-1.
The end housing 12 has a peripheral ring 34 internally threaded as at 35 for the reception of the complementally threaded portion 36 of a nut 37. The nut 37 has a rear cylindrical bore section 38 of a diameter to receive the body 31 of the cartridge 30 and a rear end face "39 for engagement with the front end of the 33. The not 37, extending forwardly of the bore section 38 has a flared or frustoconical bore section 49 for guiding and compressing the rim 33 upon movement of the rim 33 therealong. The not 37 can have a knurled band 41 therealong to facilitate manual turning. The end housing 12 has a rim seating plate 42 secured thereto in any desired manner, such as by a screw 43. The plate 42 has a forwardly extending central portion with a curved seat 44 to urge the rim 3'3 radially outwardly upon engagement of the rim 33 therewith by tightening of the nut 37.
The mode of operation will now be pointed out.
If desired, for the initial installation of a cartridge 3! the nut 37 can be slipped over the body 31 so that the end face 39 is brought into engagement with the end of the rim 33. The nut 37 can then be inserted into the end housing 12 with the threads 36 engaged with the threads 35. Upon tightening of the nut '37 the rim 33 is brought into engagement with the seat 44, and further tightening of the nut 37 tends to spread the rim 33 slightly to provide a strong grip. As the piston 16 is advanced by movement of the trigger 19' with ratchet 2-1 engaging the teeth 18, the contents of the cartridge 30 can be de livered as determined by the movement of the trigger 19. The ratchet 24 prevents undesired reverse movement of the piston rod 15.
When the contents of the cartridge 30 have been discharged, or if it is desired to remove the cartridge for any reason, the piston rod 15 is turned upwardly a sufficient extent to release the ratchet teeth :18 from their engagement by either or both of the ratchets 21 and 24 and retracted a short distance.
Upon loosening the nut '37 so that the end face 39 does not hold the rim 33 against the seat 44, the flexibility of the rim 33, upon application of a manual wtihdrawing force will permit unseating of the rim 38 from its engagement with the end face 39. The rim 33 can then be drawn through the bore 38 (see FIG. 5) and the bore 49 for complete separation of the cartridge 30.
Upon initial or subsequent installation of a cartridge 39, with the nut 37 partially loosened or backed off, the rim 33 of a cartridge is first introduced into the bore 49 and upon further inward movement through the bore 38 in distorted condition (see FIG. 5). Upon still further inward movement just past the end face 39 the rim 33 expands, with the body 311 along and close to the bore 38. Upon tightening of the nut 37 the rim 33 is gripped and held as previously explained.
The cartridge 30 can readily be inserted or removed with the nut 37 in place but retracted from its gripping position whereby a saving of time and effort is effected. The insertion and removal of a cartridge 30 does not require any special skill nor special tools.
