June 20, 1950 w. A. SHERBONDY DISPENSING DEVICE FOR CALKING MATERIAL AND THE LIKE Filed Aug. 1, 1946 Wbmm CZ. m;
INVENTOR Fatented June 20, 1956 UNITED DISPENSING DEVICE For: oALkiNG MATERIAL AND THE LIKE William A. Sherbondy, Shaker'Heightsfol'iio Application August 1,1946; Serial1Nor687,735:1 m 5.:1:
This invention relates to a dispensing device for caulking material and the like comprising a cartridge adapted to contain such material and provided with a funnel and formed for ready mounting in a caulking gun to enable the discharge of the contents directly from the cartridge without smearing the interior of. the gun or clogging the discharge.
The present invention is an improvement on .the cartridge and gun combination of Patent No. 2,106,577, issued January 25, 1938, to William E.
Sherbondy. The apparatus of that patent had a cartridge with a comparatively small spout adapted to coact with a gasket within a comparatively restricted discharge passageway in closure member of the gun. Difiiculties have been" encountered however with the clogging by the viscous caulking compound in the narrow discharge passageways of the spout and gun, as such compound is frequently of such a nature that thegun cap, effectively preventing any leakage back into the gun and doing away with the necessity of a gasket.
The above and other objects of the invention .and'the means by which they are accomplished 1 Claim. (01; 2225183 are thoroughly explained in the following dedispensing apparatus of a type known as a caulking gun containing my improved cartridge with its discharging funnel, the gun barrel, cartridge and funnel being shown in section; Fig. 2 is an end view of the funnel of the cartridge; Fig. 3 is a diametric section of the funnel; Fig. 4 is a diametric section of the end closure with the cartridge at the discharge end; Fig. 5 is a face view of such end closure, and Fig. 6 is a side elevation on a reduced scale and partly broken away of my cartridge as delivered loaded.
In Fig. 1, I0 indicates the body of the cartridge which is a cylindrical tube preferably of paper or similar material. This tube may be wound spirally after the manner of a mailing tube or otherwise made as desired. When loaded is closed 3 connection at that end.
H The internal 2 at each end. The. cicsure' for one; end (which is the right handend in Fig. 1 is. shown as comprising an internal flanged capg. I2 which is adapted to be pushed into the cartridge barrel and act as a piston in expellingit and is shown in original position in .Fig; 6 and in an intermediate location in Fig. 1.
In addition to this internal cap [2, which may be of paper I place about the, exterior in the right hand endof. the cartridge a flanged metal cap; 29, Fig. 6. The cylindrical wall of the cartri dge barrel becomes compressed between. the
fiangeof the internal cap and theflange of the external leap 29 and thus maintains a tight Atthe left handend of the cartridge shown .in Fig; 1, which is thedischarge end, I place an internal .cap 20, preferably of metal within the me ber i cap at-the discharge endis formed with adished central portion 2| having a discharge opening 22, then an annular portion v23, a ,|cylindrical portion and finally, an out- ,wardradialflange 25. When put in place in the cartridge barrel, as shown in Fig. 4, the cylin- -,drical, wall ;24' of-the cap snugly engages the in;
terior of the cartridge wall and the flange 25 of the cap abuts the end of the cartridge wall, and insures the internal cap being in place. 1 The discharge funnel is preferably of sheet metal, has the conical portion open at its end 32 in'the form of a'comparatively small central dis,- change aperture, while the other end of the conical portion has an internal diameter, only slightly. less than that of the cartridge barrel. At this larger-'endis an outward radial flange '33 and from the outer edge of this flange extends a substantially cylindrical skirt 3|. This. skirt is incompletely annular being separated a short distance at one point, as indicated at 35, in Fig. 3. The interior diameter of the skirt 3| is normally slightly less than the external diameter of the cartridge wall or the leap flange 25, and the extreme edge of the skirt is chamfered outwardly,
indicated at 36 in Fig. 3.
Hence when the skirt of the funnel is forced into place over the exterior of the wall it is sprung slightly outward and by reaction effectively clamps the cartridge wall between said skirt and the cylindrical portion 24 of the internal cap. This insures a tight closure at this end.
The discharge opening 22 in the cap 20 is closed when the cartridge is not to be used by a small frangible covering, as a piece of paper indicated in broken lines at 28, Fig. 5, and thus the cartridge is in condition for ready transportation or storage with its contents effectively contained within it. When this paper is broken away by the insertion of any suitable instrument through the opening 32 of the funnel the loaded cartridge is in condition for installation and use in the gun.
In Fig. l, I have illustrated a conventional caulking gun having a cylindrical barrel 40, a conical cup 4| secured on the discharge end thereof, and handle and operatingmechanism secured on the other end. The conical closure 4| of the gun is shown with a short cylindrical extension 42 externally threaded for the applica- "tionof any suitable discharge conduit, if desired.
The handle mechanism, as shown; comprises a ":hollow hand grip 43 which may be sw'iveled to a cap 44 screwed onto the gun barrel. The hand grip carries a, lever 45, pivoted at 46, which may operate suitable mechanism not shown, within the hand grip to engage andfeed forwardly a rod '41, the forward end of. which carries a disc 48 adapted to abut against the inner cap I2 of the cartridge. Accordingly, when the cartridge is in the gun successive manipulations of the lever *may periodically shove the cap l2 along in the barrel of the cartridgeand thus-expel the con- 'tents as desired through the discharge funnel.
As shown in Fig. 1, thegun barrel 'is provided with a suitable internal shoulder "49- Whichthe head end of the cartridge may engage. Thecar- *tridge has suchlength-with reference to the-gun in which it is to be used 'that 'when it"is put in the gun with its headend engaging the-abutment 49,the conical wall ofthe'discharge funnel makes a tight connection with theconicalwall'll -of the gun closure slightly back from the-discharge "end of the funnel, as s'hown'lin Fig. l. 'A'ccordingly, as the compound is'expelledby the advancing cap plunger' li through the 'op'ening 22 and the funnel 383, it all passesto-the exterior of the :gu'n-without danger of working back into the gun.
'lt will'be'seen that I have provided a cartridge -'effectively closed at each end'a'dapted for con- -'taining heavy viscous material such as talking compound, etc; that suchcartridge is ready for installationin the gunm'erely by removing and discarding the external cap *29 at one end and puncturing the seal'28 at the other; th'enafter the conical closure of the gun barrel is removed the cartridge is ready'foriinsertion.andiwhenithe gun barrel closure is returned to positionnthe cartridge is firmly clamped longitudinally and is =sults in .a tightconnection or these two metal parts, as the cartridgeis held by its rear end firmly abutting the gun shoulder 49.
By having the conical cap 4| of the gun threaded onthe gun barrel, as shown in Fig. l,
a considerable latitude is allowed in the position of a cap and accordingly even though there may be some variation in the length of the cartridge the-closure-member 4| may be turned on until the annular shoulder, where the conical portion of the-cap merges into the cylindrical extension, is forced firmly against the conical surface of the funnel.
Accordingly, a, verytight connection maybe made between thegun cap 4! and the funnel, though both of these parts may be of metal. This avoids the necessity of using any gasket, which experience has shown is liable to deteriorationor destruction in'use.
I claim:
In a dispensing device for calking material and the like having mechanism for forcing calking material-from a cartridge, 3, barrel adapted to receive a tubular-cartridge of calking "material and having a conical shapeddischarge formation projecting from one 'endthereof, anda'cartridge adapted to be'received in said 'barrel,-.said cartridge havinga funnel formation projecting from one end thereof and havingai'discharge opening, said funnel formation being disposed coaxial with said conical formation andadapted -to engage-the latter when 'the cartridge'is in said barrel, the angle between opposite outer sidesof said funnel formation being appreciablyilessthan 1 the angle between opposite" inside surfaces of said conical formation whereby the outer=surfaces1of the funnel'formationengage the inner surfaces of said conical formationwithin -a*relatively narrowann'ular area of said conical formation.
