2 Claims.
This invention relates to improvements in air pressure caulking guns wherein the caulking material is ejected from a container by the action of air pressure applied to a piston mounted in a cylinder and controlled by a trigger means whereby the output of caulking compound is under the control of the operator.
The principal object of this caulking gun is the provision of a gun adapted to receive the standard caulking compound cartridge and to discharge the caulking compound therefrom by manually controlled pneumatic means.
Another object of this invention is the provision of a caulking gun adapted to receive and hold a caulking compound cartridge and having means for ejecting the empty cartridge from the gun.
Other objects are simplicity and economy of construction, ease and eciency of operation and adaptability for use in handling various types of material containing cartridges.
With these objects in view as well as other objects which will appear during the course of the specification reference will be had to the drawings wherein:
Figure 1 is a side elevation of a pneumatic caulking gun embodying this invention.
Fig. 2 is a plan view of the caulking gun shown in Fig. 1.
Fig. 3 is a longitudinal sectional view taken on line III-III of Fig. 2 with some of the parts in elevation.
Fig. 4 is a sectional View taken on line IV-IV 4of Fig. 3.
Fig. 5 is an enlarged sectional View of one of the trigger controlled air valves.
Throughout the several views of the drawings like reference characters refer to similar parts and the numeral I0 designates a tubular member or barrel provided at its one end portion with an air tight chamber or cylinder I2, and at its other end with a cartridge receiving compartment I4. Chamber I2 includes a cylinder lining I6 having an inner end plug I8 carrying a centrally disposed stuffing box 26 adapted to receive a piston rod 22 therethrough to extend into the compartment I4 where it is provided with a piston head 24 and to extend into the air tight chamber to terminate in a double acting piston head 26 which is acted upon by air under pressure admitted to the chamber at its opposite ends through inlet ports 28 and 30. This outer end of chamber I2 is closed by means of a cap I3.
The catridge receiving compartment is halved longitudinally at 32, to form an upper lid 34 which is provided at its outer end with hinge member 36 pivoted to an end cap 38 which is securely xed to the outer end of tubular member I6. This end cap is provided with an axially flanged port 40 provided at its outer extremity with a delivery tube 42 which directs the caulking material to the place of deposit. Mounted in the inner extremity of port 4I) is a bushing 44 having reduced end portions 46 and 48 to respectively ilt into port 40 and port hole 56 formed into the bottom 52 of caulking material receiving cartridge 54 which snugly ts into the cartridge receiving compartment. The bottom of cartridge 54 is flanged at 56 to enter a notch 58 formed in the hinge member 36. Hinge member 36 is pivoted to end cap 38 by pintle 6l).
The cartridge 54 comes packed with a lid for holding the material in position and a plug to ll port hole 50. To charge the gun the operator unlatches latch 62 from keeper 6-4 and swings the substantially semicylindrical lid to the open position, then removes the cap and plug from the cartridge 54, andplaces it in the lid with the ange 56 near notch 58. With piston. 24 fully retracted the cartridge may be moved into the operative position in the cartridge receiving compartment and the lid latched into position. Compressed air may then be applied to the outer end of piston head 26 through port 30 to force piston 24 into the cartridge to force it into position into notch 58 and the reduced end 48 of bushing 44 into port hole 50. When the cartridge is so positioned and has been emptying the piston head may be retracted by closing port 30 and opening port 23 to permit the application of pressure air to move piston head 24 out of the cartridge 54, after which latch 62 may be released and the lid lifted, whereby the cartridge will be lifted from its position in compartment I4, and ejected from the device.
.A valve block 66 is securely attached to tubular member I by means of U-shaped straps 68 which are secured to the block by cap screws 10. Mounted in block 66 and extending therebelow is a pair of similar longitudinally spaced apart air control valves 'I2 and 'I4 which serve to regulate a ovv of compressed air to ports 28 and 30 which is delivered to block 66 through inlet pipe 76 from a source not shown.
A trigger member 'I8 bifurcated at its upper portion to present arms 80 and 82, by means of which it is pivotally mounted in block 66 by means of pin 84. A hand grip 86 secured to the lower side of block 66 by means of screws 88 is provided With an opening 96 at its upperI extremity to receive a valve operating linger 92 there- 3 through. This finger is integral with trigger 18 and is disposed opposite a similar nger 94 which is integral with the opposite side of said trigger. The fingers 92 and 94 are respectively in the path of travel of the valve stems of valves 12 and 14.
Valves 12 and 'M are similar except that one is mounted in a right hand position and the other in va left hand ,position in the block, however the `general structure of both valves is shown in cross section in Figure 5.-
These valves each comprise a body member 96 centrally bored at 98 and provided with a valve 199 having a stem |02 which yextends in the path of travel of the trigger finger whereby it can be raised 01T the valve seat 1114 to admit compressed air from inlet pipe l through passageway |96, to passageway |08 thence to Valve chamber Ill). Springs I2 normally hold valves |69 in the closed position. Valve |09 is provided at vits upper extremity with a valve member H4 which cooperates with valve seat H6 to control the exhaust port 11.8. When the valve |68 is closed, valve H4 will be open .to permit free eX- haust of air from Vcylinder 'l2 at one side of the piston 26 through passageway 1.20 and air port 28, however when the valve |99 `is open as shown in Fig. valve H4 is closed to insure the passage of compressed gas to the cylinder i2. When the operator reverses the movement of the trigger member 18, valve ld will .be open and .the air will be admitted through passageway |22 through air inlet port 30 to cylinder i2 and exhaust port I 24, will be closed.
It will be noted that the trigger member 'i8 is provided with a iinger loop |26 by means of which the operator may move the trigger in either direction to control valves 1,2 yand M.
AA pressure relief valve 26 is provided in passageway 1.96 to prevent excessive pressure .being applied t0 cylinder l2.
