Abstract
Abstract A device for use in removing condensate from rotatable, steam dryer drums. The device includes a pick-up head and a curved tube connected to the head at one end with the opposite end extending at right angles to the one end for connection to an outlet conduit leading out of the dryer drum. The pick-up head is located adjacent the inner surface of the drum and is maintained in this position by support means connected to the tube. The support means has a support member bearing against the wall of the drum in diametrically opposed relation to the pick-up head. The support means can be adjusted and locked in different positions to maintain the pick-up head in its proper position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A device for use in removing condensate from the interior of a rotatable steam dryer drum comprising: a. a condensate pick-up head b. a substantially rigid unitary pick-up tube, one end of the pick-up tube connected to the pick-up head, the opposite end of the pick-up tube having means for connecting it to an outlet conduit leading from the drum, the pick-up tube being continuously curved substantially throughout its length to have its opposite end extend in a direction substantially transverse to the direction in which the one end extends, c. support means connected to the pick-up tube and terminating in a free end which extends in a direction substantially transverse to the direction in which the opposite end of the pick-up tube extends, d. threadably adjustable means mounted on the support means at its free end, and means provided for locking the threadably adjustable means, e. said support means including a substantially rigid unitary support tube continuously curved substantially throughout its length and being substantially symmetrical with said pick-up tube, and f. a bracing member connected between and being substantially axially concentric with said pick-up tube and said support tube.
Claim 2
Independent Claim
191 words
A device for use in removing condensate from the interior of a rotatable steam dryer drum comprising: a. a condensate pick-up head b. a substantially rigid unitary pick-up tube, one end of the pick-up tube connected to the pick-up head, the opposite end of the pick-up tube having means for connecting it to an outlet conduit leading from the drum, the pick-up tube being continuously curved substantially throughout its length to have its opposite end extend in a direction substantially transverse to the direction in which the one end extends, c. support means connected to the pick-up tube and terminating in a free end which extends in a direction substantially transverse to the direction in which the opposite end of the pick-up tube extends, d. threadably adjustable means mounted on the support means at its free end, and means provided for locking the threadably adjustable means, e. said support means including a substantially rigid unitary support tube continuously curved substantially throughout its length and being substantially symmetrical with said pick-up tube, and f. a bracing member connected between and being substantially axially concentric with said pick-up tube and said support tube.
Claim 3
Dependent Claim
34 words
A device as claimed in claim 1, wherein the pick-up head comprises a substantially rectangular plate having a central passageway extending therethrough, said passageway having a radiused inlet at one surface of said plate.
Claim 4
Dependent Claim
55 words
A device as claimed in claim 2, wherein legs of equal length are rigidly connected to said one surface of the rectangular plate and extend therefrom to support the plate in spaced relation to the drum and thus provide a peripheral gap of varying dimension through which the condensate can be drawn to the inlet.
Claim 5
Dependent Claim
71 words
A device as claimed in claim 1, wherein the threadably adjustable means includes a shaft having a pair of ends and being threaded at a first end, the first end being at least partially inserted into the support means at the free end the shaft carrying a pressure pad at its second end, said locking means including nuts threaded on the shaft cooperating with the free end of the support means.
Claim 6
Dependent Claim
41 words
A device as claimed in claim 4, wherein the pressure pad comprises a thin plate fixed centrally thereof, at one surface, to the shaft, and having legs extending away from the other surface, the legs offset or spaced from the shaft.
Claim 7
Dependent Claim
51 words
A device as defined in claim 1 wherein said threadably adjustable means includes a threaded shaft and partially inserted in said support tube, and a pressure pad attached to said shaft whereby relative movement of said shaft and said support tube are achieved only by movement of said threadably adjustable means.
