GUN FOR TWO COMPONENT ADHESIVES Filed July 12, 1961 2 Sheets-Sheet 2 INVENTORS. C riI J. Herman avid 611th, 5r.

AGENT United States Patent 3,117,695 GUN FDR WK) CGMPONENT ADEESIVES Cyril 3. Herman, Riverside Conn. (116 S. Main St, Portville, N.Y.), and David C. Gnth, Sax, Westport, Conn. (23 Sweetgum Road, Levittown, Pa.) Filed July 12, 196i, gar. No. 123,979 7 Claims. (8i. 222-137) This invention relates to guns or dispensing devices for t.vo component adhesives wherein two components or" an adhesive substance set up comparatively quickly when mixed together and so cannot be stored in a single container, or in use, re said to have a pot-life of the order oi hours rather than Weeks or months necessary for a reasonable shelf-life.

One example of such adhesives is epoxy resin which is mixed for curing with an amine such as triethylene tetramine. Such a system is well known to the art. Another is the polyurethane system. Often powdered aluminum or silica flour is added to one of the components or mi):- ture to give greater adhesion.

An object of the invention is to provide a device of this kind by wmch the two components may be mixed substantially at the point of application in proper proportions.

Another object is to provide a device of this kind which is small and light enough in weight to be held in the hand for easy manipulation and yet will contain completely therein some of each component.

Another object is to provide a device of this kind in which there is a mixing chamber of very small size.

Yet another obiect of the invention is to provide a device of this type in which the danger of clogging is reduced to practical limits.

And still another object of the invention is to provide a dispenser in which comparatively small quantities of each of the two components may be loaded, as for example, from a collapsible tube, so that small quantities of the components may be purchased and used in small amounts.

The attainment of these objects is reached, in a guntype applicator or dispenser which, briefly described, comprises two storage cylinders for the two separate components of the adhesive having a common dispensing head thereon and provided with an expelling and mixing plunger rod. Means are provided to reciprocate the rod and at the same time meter increments of the components from the cylinders to the head.

In the accompanying drawing showing, by way of example one of many possible embodiments of the invention,

FIG. 1 is a plan of the dispenser;

FIG. 2 is a side view of the dispenser with parts in one position;

FIG. 3 is a side view of the dispenser with parts in another operational position, and

FIG. 4 is a schematic representation of elements of the metering means.

The applicator comprises a body generally designated 19 having a pistol grip handle 11; and a forward or cylinder-carrying portion 12 generally symmetrical about the vertical mid-plane having left and right spaced socket members 14:: and i lb provided with parallel cylindrical recesses 15:: and 15b.

Axially parallel storage cylinders 16a and 16b for the two components are mounted fast in the recesses and project forwardly generally as does the barrel of a revolver, and may be substantially closed at their rear as at 18. These cylinders are provided with rather tightly fitting pistons 13a and 1% having threaded rods ids and Zilb fast thereon and extending rearwardly through holes 21 in the body ill and above the handle.

etented Jan. 1%5

The forward portions 22 of cylinders 16a and 16b are provided with a symmetrical head 24 with recesses 25:; and 25/) having a medial longitudinal bore or small mixing chamber 26 between the recesses 25a and 2512 which have each an annular end wall 28 and a further recess of reduced diameter 21 and 2% respectively.

The head is provided with laterally opening ports and 3% internally threaded as at 31 and for communication from the exterior to the interior of the respective storage cylinders ahead of the pistons. Collapsible tubes containing the separate components may be used to load the cylinders through the ports, particularly tubes having necks threaded to lit the port threads 31 so as to reduce the chance of spillage, which ports are sealed as by screw plugs 32.

The recesses 29:; and 2% terminate somewhat conically as at 35 and straight duct bores 34a and 34b connect the chamber bore as as at 36 in the conical zones with the interiors of the cylinders lea and 16b. it is to he noted that these duct bores extend onwardly to the ports Sila and 3&5 at such an angle that, say, a wire may be inserted into the duct from the port in the event the duct bore becomes clogged. For ease of use, the forward end or" the head at the chamber bore 26 is formed somewhat as a nozzle 38.

A plunger rod 3%, preferably of nylon plastic or fluorinated plastic material such as Teflon, both of which have low adhesion to epoxy and urethane resins, is disposed in the chamber bore, projecting rearwardly between the two cylinders, for reciprocation and rotation in the chamber bore. Preferably the head 24 is of steel, stainless steel, or aluminum, and the chamber bore 26 about 0.601 inch larger in diameter than the plunger rod 39. With this clearance and choice of materials just mentioned, there is substantially no danger of fouling in normal use.

The limits of reciprocation by the plunger rod are such that the outer end 4% of the rod projects from the head slightly in extreme forward position and is retracted bethe duct bore junction 36 upon Withdrawal.

The plunger rod 39 is rotated by a somewhat ring sector or Ll-shaped gear member ll having laterally projecting teeth .2 engaging with teeth 44 on the plunger rod extending thereon for a sufficient distance so that the two sets of teeth may be engaged during the reciprccatory motion of the plunger while the teeth 42 move in a somewhat circular path in a vertical plane.

The member is pivoted at one end 45 of an arm thereof to the body it; between and under recesses and at 43 and is held suiiiciently close to the teeth or" the rod by, as shown, the right cylinder 16b. The arm occupies the normal trigger position of a revolver and oscillation of the gear member causes the plunger rod to sp '1 back and forth.

Reciprocation of the plunger is accomplished by a lon gitudinal movement of a bearing 3% carrying the rear end portion 5i) of the plunger at a part 51 of reduced diameter. The bearing is pivotally mounted, as at 5'2, about midway on the lower arm 54 of an inverted L-shaped lever rocker 5S pivoted at as on and between upwardly projecting arms 53 on the body it The lower portion 52 of the rocker arm 54 is provided with a longitudinal slot 6% receiving a pivot pin 61. fast on the gear member arm 46 below its pivot 48. This combination provides a loose linkage between the arms 46 and 54 permitting the arm 5'4 to be drawn rearwardly in trigger fashion. The rocker and gear member arms 54 and 46 are biased to forward position by a spring 62 mounted on the handle 11 so that the end 4% of the plunger is normally in projecting position from the nozzle 35.

Feed to the mixing chamber bore 26 through ducts 34a and 34b is obtained by metered forward movement cameos of pistons 1M and 29b in predetermined increments. To end, gears 6 in and having tlueaded central holes threaded on the respective piston rods and 2% and disposed in a transverse s ot 65 in the body it to be turned in increr eats. T turning is carried out l y ratchet w eel means do, well lmown to the art, on ast one of th gears, and actuated by a vertically reclprocatory rmllient strip es having a hook 6'7 to enthe wheel and pivoted to the upper arm 59 of the oclrer, as at $6, where it overhangs rearwardly the slot 1 A friction washer may be provided between the ratchet wheel and the wall to the slot necessary.

in order to avoid the need for left handed threads on a gear and piston rod set and to use only one ratchet, though these avoidances not necessary, an intermediate gear 7% may be provided. indeed it may be desirable to have an additional strip 6 havin a hook to engage ratchet wheel on the gear 614:. This makes the system of FIG. 4 double acting, and by the omission of the gear 76' and varying the er iective range of the movement of the strips 68 and the rates of travel of the pistons can be varied.

in use, collapsible tubes containing the components are first screwed into ports and with the metering pistons forward position. The pistons are then forcibly turned, as by a crank (not shown) fitted on the squared ends ll of the piston rods, to retract the pistons in the cylinders, the threaded gears being held against;

tut ag if necessary. This, attended by, if necessary, a squee g on the tubes, charges the cylinders 15a and too with the separate components and the tubes are then removed and ports closed with their plugs.

Upon drawing on the trigger-like gear member arm 54, the pluner is retracted in the chamber bore 26, uncoveri the ducts Meanwhile, the rocking of the L-shaped rocker 55 lifts the ratchet strip 68 causing the wheel 66 and gears --.1 and 64b to turn about the piston rods and advance the pistons and force an increment of each component into the chamber bore.

Upon release of the trigger the plunger advances in the chamber bore with a spinning action, the pointed end "it? of the plunger aifording greater surface for contact with admitted components so that the two compo nents are mixed in the chamber bore as they become expolled therefrom,

If the ratchet system is double acting, pressure builds up in the cylinders during forward motion of the plunger past the duct 3%. Generally this is not desirable but in the case of thin components, the additional pressure with the plunger in forward position sometimes tends to make them stick to the rear portion of the plunger and foul up. Cm the other hand, wit thicker components, it is desi able to h ve pressure building up during the forward stroke of the plunger so that how of the components into the chamber bore is more rapid when the duct passages become uncovered. The action of either of the ratchet strips 68 or -53 may be eliminated by merely holding the appropriate strip away from its Wheel.

By having the plunger biased to forward position the amount of mixed adhesive left in the chamber bore is kept to a min mum. This advantage is enhanced by having the pistons act only during retraction of the oying appropriate ratcheting.
