Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
339 words
An implement comprising a rigid elongate, cylindrical member provided with a grip portion by means of which it may be wielded to deliver a blow and containing an axial chamber open at one end defined by a thick wall capable of sustaining a blow, said chamber being of a size such as to be capable of receiving a cartridge of pressurized material, a cartridge of pressurized material disposed in said chamber, said cartridge having a discharge tube operable by axial displacement relative to the cartridge to release the pressurized material and being disposed with the discharge tube at the open end of the chamber, a cap mounted in the open end of the chamber, said cap comprising a head and neck, said neck containing a passage, one end of which is situated in the base of the neck in coaxial alignment with the discharge tube and within which a portion of the discharge tube extends and the other end of which is situated in the side of the neck, the wall of said chamber containing a discharge hole with which said other end of said passage is adapted to be aligned, a pin fixed in the wall of the chamber with an end extending radially into the chamber, and a multilimb recess in the side of the neck within which the inwardly projecting pin is engaged, said recess having a first axial portion arcuately spaced from said end of the passage which, when aligned with the pin, enables rotating the cap to lock the cap against axial movement with said end of the passage out of alignment with the discharge hole, a peripheral portion which, when aligned with the pin, enables rotating the cap to lock the cap against axial movement with said end of the passage out of alignment with the discharge hole, and a second axial portion which, when aligned with the pin, enables pressing the cap axially toward the discharge tube to align said end of the passage with the discharge hole and to effect discharge.
Claim 2
Dependent Claim
339 words
An implement comprising a rigid elongate, cylindrical member provided with a grip portion by means of which it may be wielded to deliver a blow and containing an axial chamber open at one end defined by a thick wall capable of sustaining a blow, said chamber being of a size such as to be capable of receiving a cartridge of pressurized material, a cartridge of pressurized material disposed in said chamber, said cartridge having a discharge tube operable by axial displacement relative to the cartridge to release the pressurized material and being disposed with the discharge tube at the open end of the chamber, a cap mounted in the open end of the chamber, said cap comprising a head and neck, said neck containing a passage, one end of which is situated in the base of the neck in coaxial alignment with the discharge tube and within which a portion of the discharge tube extends and the other end of which is situated in the side of the neck, the wall of said chamber containing a discharge hole with which said other end of said passage is adapted to be aligned, a pin fixed in the wall of the chamber with an end extending radially into the chamber, and a multilimb recess in the side of the neck within which the inwardly projecting pin is engaged, said recess having a first axial portion arcuately spaced from said end of the passage which, when aligned with the pin, enables rotating the cap to lock the cap against axial movement with said end of the passage out of alignment with the discharge hole, a peripheral portion which, when aligned with the pin, enables rotating the cap to lock the cap against axial movement with said end of the passage out of alignment with the discharge hole, and a second axial portion which, when aligned with the pin, enables pressing the cap axially toward the discharge tube to align said end of the passage with the discharge hole and to effect discharge.
Claim 3
Dependent Claim
129 words
An implement according to Claim 1, wherein said peripheral portion is situated at such a distance from the base of the neck that when the pin is engaged therein the base of the neck is held retracted with respect to the discharge tube, wherein the second axial portion is at one end of the peripheral portion and extends therefrom a distance such that when the pin is engaged with said second axial portion the base of the neck is displaceable a distance toward the discharge tube sufficient to effect discharge and wherein said first axial portion is intermediate the ends of the peripheral portion and opens through the base such that when the pin is engaged with said latter portion the cap may be removed axially from the chamber.
Claim 4
Dependent Claim
32 words
An implement according to claim 1, wherein said portions of the recess are interconnected so that the cap may be manipulated from one position to the other by rotational and axial movement.
Claim 5
Dependent Claim
35 words
An implement according to claim 1, wherein the end of the passage in the side of the neck has set into it an orifice plate adapted to discharge the pressurized material in a fine stream.
Claim 6
Dependent Claim
29 words
An implement according to claim 1, wherein the discharge hole is of larger size than the jet orifice to permit the jet to pass freely through it without deviation.
Claim 7
Dependent Claim
39 words
An implement according to claim 2, wherein the other end of the peripheral portion has an upwardly sloping bottom such as to effect jamming of the pin against the bottom when the cap is rotated to said locking position.
Claim 8
Dependent Claim
72 words
An implement according to claim 1, wherein spacing pins are fixed to the head of the cap peripherally of the neck of a length such that when engaged with the end of the wall the cap is held against axial displacement in a direction to effect discharge, said wall containing openings so located that when the cap is situated in the position for discharge said spacing pins are aligned with said holes.
Claim 9
Dependent Claim
18 words
An implement according to claim 7, wherein there are three such pins and a corresponding number of holes.
Claim 10
Dependent Claim
33 words
An implement according to claim 1, wherein a coil spring is disposed about the discharge tube with its ends engaged, respectively, with the top of the cartridge and the base of the neck.
Claim 11
Dependent Claim
46 words
An implement according to claim 1, comprising a plurality of axially disposed spacers and openings between the cap and the adjacent end of the chamber operable in one position of the cap to prevent axial movement thereof and in another position to permit such axial movement.
Claim 12
Dependent Claim
76 words
An implement according to claim 18, comprising a spacer pin disposed diametrically of the neck at its junction with the head, the opposite ends of which protrude from the neck between the head and the end of the club, and wherein there are notches in the open end of the chamber for receiving said protruding ends of the pin when the cap is turned to its operative position to permit depressing the cap to effect discharge.
Claim 13
Dependent Claim
68 words
An implement according to claim 1, wherein there is a latch bar secured to the head with an end arranged to overlap the end of the club in which the cap is rotatably mounted, said end containing a notch, and wherein said pin has an extension protruding from the wall of the chamber for engagement with said notch to assist in holding the cap in its locked position.
Claim 14
Dependent Claim
25 words
A club according to claim 12, wherein the interengagement of the notch in the latch bar with the pin prevents accidental rotation of the cap.
Claim 15
Dependent Claim
33 words
An implement according to claim 1, wherein the head of the cap contains a depressed thumb print disposed diametrically in alignment with a diameter passing through said pin and through said nozzle orifice.
Claim 16
Dependent Claim
24 words
An implement according to claim 14, wherein the thumb print depression enters the head of the cap from the side opposite the nozzle orifice.
