Abstract
Abstract Apparatus for injecting sizing and similar textile treatment solutions into a tumbler clothes drycleaning machine, or the like. The treatment material is injected in mist form into the vacant space in the rotary drum of the machine by a stationary nozzle located to register with a slot in the flange of the rotating drum, the nozzle having a valve which is automatically operated by a cam located on the drum flange adjacent the slot.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
100 words
In a clothes processing machine, a rotating clothes tumbler cylinder, said cylinder being formed with an injection aperture spaced from the cylinder axis, an inwardly directed injection nozzle mounted on the machine substantially at the same radial distance from the tumbler cylinder axis as said aperture and being at times registrable with said injection aperture during the rotation of said cylinder, a source of textile treatment solution under injection pressure, and means to communicatively connect said source to said nozzle responsive to the registration of said injection aperture with said nozzle, whereby to spray textile treatment solution into the cylinder.
Claim 2
Dependent Claim
100 words
In a clothes processing machine, a rotating clothes tumbler cylinder, said cylinder being formed with an injection aperture spaced from the cylinder axis, an inwardly directed injection nozzle mounted on the machine substantially at the same radial distance from the tumbler cylinder axis as said aperture and being at times registrable with said injection aperture during the rotation of said cylinder, a source of textile treatment solution under injection pressure, and means to communicatively connect said source to said nozzle responsive to the registration of said injection aperture with said nozzle, whereby to spray textile treatment solution into the cylinder.
Claim 3
Dependent Claim
35 words
The clothes processing machine of claim 1, and wherein the means to communicatively connect the source to the nozzle includes a valve, and means to open said valve when the nozzle registers with the aperture.
Claim 4
Dependent Claim
42 words
The clothes processing machine of claim 1, and wherein said nozzle is located in a radial plane at a substantial angle beyond the vertical plane of the axis of rotation of the tumbler cylinder in the direction of rotation of the cylinder.
Claim 5
Dependent Claim
14 words
The clothes processing machine of claim 3, and wherein said angle is approximately 30*.
Claim 6
Dependent Claim
48 words
The clothes processing machine of claim 2, and wherein the means to open said valve comprises a cam on the tumbler cylinder and valve-opening follower means on the machine operatively connected to said valve and located to engage said cam when the nozzle registers with said injection aperture.
Claim 7
Dependent Claim
17 words
The clothes processing machine of claim 5, and wherein said cam is located adjacent said injection aperture.
Claim 8
Dependent Claim
35 words
The clothes processing machine of claim 5, and wherein said tumbler cylinder is provided with a front annular flange, said injection aperture being located in said flange and said cam being mounted on said flange.
Claim 9
Dependent Claim
31 words
The clothes processing machine of claim 7, and wherein said aperture comprises an arcuate slot coaxial with the cylinder and said cam is located adjacent and substantially parallel to said slot.
Claim 10
Dependent Claim
27 words
The clothes processing machine of claim 8, and wherein said cam is substantially angularly coextensive with said slot with respect to the rotary axis of the cylinder.
Claim 11
Dependent Claim
58 words
The clothes processing machine of claim 9, and wherein said valve comprises a solenoid valve mounted on the casing and the means to open the valve includes a source of current, a switch having an inwardly projecting operating element engageable with said cam, and circuit means connecting said source of current to said solenoid valve through said switch.
Claim 12
Dependent Claim
50 words
The clothes processing machine of claim 5, and wherein said machine is provided with a hinged support plate, said valve and said follower means being mounted on said hinged support plate, said support plate being at times swingable away from a position wherein the follower means can engage said cam.
Claim 13
Dependent Claim
27 words
The clothes processing machine of claim 11, and means to releasably lock the hinged support plate in said position wherein the follower means can engage said cam.
Claim 14
Dependent Claim
101 words
The clothes processing machine of claim 1, and wherein said nozzle is located in a radial plane at an angles spaced from the vertical plane of the axis of rotation of the tumbler cylinder, said cylinder being rotatable in opposite directions, a second inwardly directed injection nozzle mounted on the machine on the opposite side of said vertical plane substantially symmetrically with respect to said first-named nozzle, and means to selectively connect said source to one or the other of said nozzles responsive to the registration of said injection aperture therewith, in accordance with the direction of rotation of the cylinder.
Claim 15
Dependent Claim
25 words
The clothes processing machine of claim 13, and wherein said nozzles are located at angles spaced approximately 30* on opposite sides of said Vertical plane.
