CALK GUN AND CARTRIDGE ADAPTER Filed Feb. 24, 1948 Fi .5 FIG. 6
INVENTOR. SAMUEL CIQ'WE Patented Sept. 22, 1953 CALK GUN AND CARTRIDGE ADAPTER.
Samuel Crewe, East Cleveland, Ohio, assignor to Crewe Manufacturing & Tool 00., Cleveland,
Ohio
Application February 24, 1948, Serial No. 10,423
1 Claim. 1
This invention relates to calk guns and particularly to the hand operated type of gun which uses a replaceable cartridge containing the calk.
Conducive to a better understanding of this invention, attention should be directed to my previous United States Patents Nos. 1,883,767; 2,111,582; 2,180,978; and 2,233,587, granted to me On October 18, 1932, March 22, 1938, November 21, 1939, and March 4, 1941, respectively, for calk guns or related apparatus. The two Patents Nos. 2,180,978 and 2,233,587 show manually operable calk guns having plunger operating devices which include internally threaded cups for engaging the metal barrels or cylinders of the guns. These metal barrels are designed primarily to contain bulk calk.
Since the granting of these two patents, it has been found desirable to provide a means whereby calk may be dispersed with these guns without the use of the metal barrel. This is due to the fact that calk made by different manufacturers may be easily purchased in cartridges at almost any hardware store. These cartridges closely resemble the cartridge described and illustrated in my prior Patent No. 2,111,582 and, in addition, each cartridge is provided with a nozzle like the one herein illustrated. These conventional and readily obtainable calk cartridges are quite durable and make unnecessary the use of a permanent barrel and nozzle. They are economical to use and are easily disposed of when empty.
The cartridges made by the different manufacturers, while of the same diameter, nevertheless vary considerably in length. Therefore, when it is desired to use a dispersing mechanism, referred to herein as a plunger operating device, such as the ones shown in my Patents 1,883,767 2,180,978; and 2,233,587, with a conventional cartridge, provision must be made for adjusting its length so as to receive the particular cartridge obtainable or at hand.
The instant invention therefor provides a means for quickly and easily converting a standard metal barrel type or bulk type calk gun to one adaptable for use with cartridges of different lengths. This is done by simply unscrewing and removing the metal barrel thereof, substituting therefore the herein described attachment, and using it with the previously patented ratchet members.
It is therefore the primary object of this invention to provide an attachment to a plunger operating device which is adaptable for use with calk cartridges of different lengths.
Another object is to provide such attachment so that it may be quickly and easily removed from the plunger operating device without the use of special tools or skill, and which attachment will not alter or effect the operating device so that it can not be again used thereafter in its regular way.
A further object is to construct the stated attachment economically and easily out of simple metal stampings, standard and easily obtainable parts.
Thes and other objects of the invention will become apparent from a reading of the following specification and claim, together with the accompanying drawing in which like parts are referred to and indicated by like reference characters and wherein;
Figure 1 is a side elevation of a calk gun made in accordance with this invention and with parts thereof broken away to show construction;
Figure 2 is a top view of the gun shown in the Figure 1;
Figure 3 is a side elevation of the gun without the calk cartridge;
Figure 4 is a top view of the gun shown in the Figure 3;
Figure 5 is a rear view of the gun shown in the Figure 3;
Figure 6 is a front view of the gun shown in the Figure 3;
Figure 7 is a top view of the back plate of the attachment member unmounted or separate from the ratchet member;
Figure 8 is a front view of the back or rear plate of the attachment member unmounted; and
Figure 9 is a side elevation of the elements shown in the Figures 7 and 8.
Broadly the invention consists of a plunger operating devic referred to and indicated as the ratchet member ill; the special attachment constituting the basis of this invention and indicated by the character 29; and the cartridge indicated by the character 48. Each of these elements will be described in detail hereinafter and in the order stated.
The ratchet member It consists of a hollow metal handle H to which there is pivoted on the pin I3 a trigger element l2 and through which handle there passes a toothed bar or rod iii. The bar It is engaged by the trigger l2 and is caused to move forward through the handle I I when the trigger is pulled or brought rearward proximate to the handle ll. Conventional pawl and dog mechanisms are mounted in the handle to hold the ratchet bar 16- when the trigger is released.
These mechanisms are broadly indicated by the character I4.
The ratchet bar It is provided with a simple crosswise grip member I"! to facilitate returning of the ratchet bar to its normal or starting position. This grip member i1 is on the rear end of th bar. The front end of the bar It is provided with a plunger or piston head l8 which engages the calk in the cartridge 40 so as to eject it when the ratchet bar is moved forward. The reference character |8a of the Figures 3 and 4 shows the plunger H3 in an alternate position and indicates reciprocal movement thereof.
The front part of the handle l-l supports a cup or socket 55 which receives the rear open end'of the cartridge 40. This cup la: is slightly longer than the piston head l8 and is threaded internally as indicated by the character l9 to firmly engage the metal barrel of the gun when bulk calk is used therein.
The attachment member or cartridge harness 28 consists of a back plate or U-shaped cup-yoke 2| made of suitable stamped metal. It is flat and has a top flange portion which when applied and used restson the top of the aforestated cup or socket Hi. It has a vertical slot 22 that is open at the bottom and engages the sides of the handle member Two side wings or ears 23 project outwardly and laterally as shown and each wing 23 is perforated and has a hole 26 to receive the 0 rear ends of the side bars 3 i.
The front plate or U-shaped nozzle-yoke 26 is also made of flat stamped metal. It i somewhat circular and has a diameter closely proximating the diameter of the cartridge 43. -It has a slot 2i open at the top for receiving the nozzle 43 of the cartridge. It, similar to the back plate 2|, has side wings or ears 26, each of which is provided with a hole 29 for engaging the front ends of the side bars 3|.
The two side bars 3| which connect the front and rear plates 26 and 2| respectively are simply pieces of bar metal threaded at each end. The front threaded ends 32 are firmly'secured to the side wings 28 of the front plate 26 by means of the hex or square nuts 34%. The rear threaded ends 33 are looselyengageable with the side wings 23 of the back plate 2| by means of the wing nuts 35. By tightening or loosening the wing nuts 35, the front plate 26 may be moved closer or farther from the back plate 2| as desired and as needed to accommodate the length of the particular cartridge to be used.
The cartridge 40 is made of durable paper or cardboard formed into a cylinder or tube 4|. It has a front cap 42 to which there is attached a nozzle 43, as shown. It has a rear inverted ca 44 made of either paper or light metal which neatly fits the inside of the cylinder 4| and receives the plunger head |B.
To'use this device, the ratchet bar |6'is.pulled 4 back as far as it will go or to its starting position; the herein described special attachment is mounted on the handle [I by simply hooking the back plate 2| over the handle I and cup l5. Next, a cartridge 40 is placed between the side bars 3| and its rear or open end inserted in the metal socket l5 so that the inverted cap 44 receiv'esthe piston head l8 somewhat as indicated by the element 46a in the Figure 1. Next, the cartridge is straightened out or aligned with the side bars 3| so that the nozzle 43 fits into the slot 21 of the front plate 26. Finally, the wing nuts 35 are tightened sufiiciently to draw the front plate rearward to firmly hold the cartridge in the position clearly shown in the Figure 2. When so assembled, the calk may be easily ejected through the nozzle 43 by the simple operation of the tri ger l2. When the cartridge is empty, it may be easily removed and replaced on the same manner.
Having thus disclosed the invention in its preferred form, it should be understood that since there may be other forms or modifications of the invention, no limitations thereon are intended except those imposed by the following claim.
'I claim:
In combination. with a bulk. calk gun of the type having a cup adapted to retain a disposable cartridge and a plunger operating device operable through said cup, a cartridge harness, comprising parallel rods adapted to retain a disposable-cartridge of calk material in said cup, comprising, a substantially U-shaped cup-yoke engageable with the rear face of said cup and adapted to straddle the operating device, the said cup-yoke having perforated ear portions extending beyond either side of said cup; a substantially U-shaped nozzle-yoke spaced from said cup-yoke and connected thereto by said parallel rods passing through said cup-yoke ear perforations, the said nozzle-yoke being adapted to straddle "the nozzle of said disposable cartridge and bear against the front end of said cartridge, and means on the ends of said rods for adjustably spacing the said cup and nozzle yokes for the purpose of retaining the said disposable cartridge therebetween and in anchored attachment to said bulk calk gun cup and plunger operating means.
