Application filed February i7, 1922'. Serial No. 537,321.
To all whom it may concern:
Be it known that I, MARTIN SwIN'rnK, a
citizen of the United States of America, and
resident of Eddyville, Wapello County, Iowa, have invented a ew and useful Travsling-Screen Suction ozzle, of which the following is a specification. V
The object of this invention is to provide improved means for screening the mouth of a nozzle employed in sand-pumping apparatus or dredges, and removing large objects such as stones from said nozzle, which mi ht otherwise clog the nozzle or pipes.
further object of this invention isto provide a traveling screen traversing the particularly means for supporting the screen 1n its travel across said mouth! 7 A further object of this invention is to provide an improved construction for- .an. arcuate track adapted to carry a screen. in its travel across the mouth of a suction noz-' zle, and means for mounting said track rel-Q ative to the nozzle.
A further object of thls-mvention is to provide anti-friction means carried by the tracks for engagement with the traveling screen;
A further object of this invention; is to provide improved liners or wear plates for the track members, which are removable and re laceable.
ith these and other. objects in ,view, my invention consists in the construction, ar-
rangement and combination of elements hereinafter set forth, pointed out" in my claims and illustrated by the accompanying dr% wing, in which 1 nozz e and arcuate track devices embodying my invention. Figure 2 is a. plan of the same, the traveling screen being omitted.
Figure 3 is a longitudinal section on the line 3-3 of Figure 2. Figure 4 is a cross-section on the line 44 of Figure 2. Figures 5 and 6 are detail cross-sections, on an enlarged scale, on the lines 5-5 and 6-6 of Figure,
3. Figure 7 is a detail cross-section, on an enlarged scale, on the line 77 of Fi re 1.
The present invention relates to an is an im rovement on the devices illustrated, descrlbed and claimed in Letters Patent Number 1,426,616 granted to me August 22, 1922, to which reference is hereby made.
In the construction of the device as shown a suitable frame is employed which is ivacross be re 1 is a side elevation showing a manner, as by a barge or the like employed in sand-pumping or dredging operations. An le track members 10, 11 are carried by an longitudinally of the upper portion of the frame, and channel track members 12,
13 by the lower portion thereof, and said track members carry a flexible traveling screen 14 adapted to e driven in any suitable manner. A pi e 15 is mounted centrally and longitudina y of the frame and is adapted to discharge sand and water at any suitable location provided, and is rovided at its forward or free end with a, ange 16. A nozzle 17 is provided and is formed with a base fiange18'by which it is attached to the flange of the pipe 15. The frame is adapted to be adjusted in such manner on its pivotal support that the outer end of the nozzle '17 rests on the bed of a stream or body'of water from which sand or the like is to be removed by pumping. The top and section, and the side wallsof said nozzle project beyond said lips to form wings 21,
'22,.the outermargins ofwhich preferably are formed on arcs. Asup orting plate 23- is formed on or fixed-toan extends transversely of the top of'the rear portion of the nozzle17- and a similar plate 24 extends lowsaid nozzle, directly beneath theplate '23. Angularbrackets 25, 26 are mounted on and bolted to the upper supi portin plate 23 and-. are oppositely arranged with t eirwertical membersoutermost, and similar'bracket's 27, 28 are similarly arranged onand depend from the lowermost supporting plate 24, the. vertical members of the brackets 27, 28 being slightly longer than the. correspondin members of the brackets '25, 26. The olts 29 which setime the brackets 25, 26, 27, 28 in place preferably pass through slotted holes 30 in the plates23, 24, as'indicated by dotted lines in igure 2, to permitvsome adjustment of the brackets relative to the longitudinal center of the device, The brackets 25, 26 are formed with'central webs 31 which are apertured and secured together by means of a strap 32 bolted thereto; and the brackets 27, 28 are formed with similar webs secured together by a strap 33-. Each bracket 25, 26 is formed on the inner face of its vertical member with a shoulder, ledge or flange 34 on which rests the forward end of an angle track member or 11 and which is securely fastened to said bracket. Each bracket 27, 28 is formed on the inner face of its vertical member with a shoulder, led e or flange contacted by the forward end of a channel track member 13 or 14 secured in lace thereon. Arcuate track members 36, 3 are provided and are suitably mounted in parallel s aced relation to form continuations of an a connection for the angle tracks 10, 11 and channel tracks 13, 14, one on each side of and extendin around the free end of the nozzle 17, sai
arcuate track members being an lar in cross-section throughout their len s. The base members of the angular track members 36, 37 rest on and are secured at their upper terminals to shoulders, ledges or flanges 38 formed on the inner faces of the vertical members of the brackets 25, 26 respectively; and at their lower terminals contact with and are secured to similar shoulders, ledges or flan 39 on the brackets 27, 28 respectively. 1 e arrangement of the parts is such that the upper surfaces of the base members at the upper terminals of the arcuate track members abut and are flush with the upper surfaces of the base members of the an le track members 10, 11 respectively; and t e lower surfaces of said base members at their lower terminals abut and are flush with the lower surfaces of the upper flanges of the channel track members 12, 13 respectively,
so that a continuous smooth track is provided for the screen 14. The side walls of the nozzle 17 flare outwardly between their ends and the wings 21, 22 are parallel. Intermediate or curved ortions of the arcuate track members 36,3 contact inner faces of the wings 21, 22 respectively and are secured thereto as by bolts or rivets 40, and the curvature of the outer ends of said wings preferably coincides with the curvature of said track members.
The screen 14 in its travel runs on and around the tracks provided by the arcuate track members 36, 37, no gears or sprockets being fiovided for said screen at its outer end. e screen may be provided with projectin lugs 41 which serve to stir and agitate t e sand or gravel bed and facilitate entrance to the nozzle and pipe in the pumping operation. The screen also serves to prevent entrance to the nozzle and pipe of any large and undesirable objects such as stones, sticks and lumps of clay, the lugs engaging and removing such objects away from the nozzle.
The base members of the arcuate tracks 36, 37 are subject to considerable friction and consequent wear by the dragging of the screen thereover, especially in the curved portions between their ends. To obviate this and provide a means for repair of worn parts, liners or wear strips 42, 43 are provided for each arcuate track member. The
aaarr base members of the arcuate tracks are rabbeted to receive the wear strips or liners 42, 43, which are held in place by bolts 44, whereby they may be removed and replaced. The track surfaces of thewear plates are of course flush with and form continuations of the track surfaces of the members in which they are mounted. Two wear ,plates are provided for each track member, each on an arc. of approximately ninety degrees and adapted to be arranged end to end, so that they may be independently removed and replaced as required.
A number of anti-friction rollers may be provided in the arcuate track members 36,
37 for engagement withthe traveling screen 14. 'In t is instance three suchare shown for each track member, one near its lower or initial end and two in its up r portion, where the greatest pulling strain is present on the screen. The rollers are designated b the numerals 45 and each extends throu an aperture 46 in the vertical flange of t e track member, beingspivoted on a pm 47 carried by a bracket mounted on the track member. The rollers 45 engage side marns of the screen 14 and tend to reduce the ictional contact with the track members.
I claim as my invention 1. In a device of the class described, a nozzle, arcuate track members secured to and carried thereby, and a flexible screen adapted to travel on said track members across the mouth of said nozzle, said track members being rabbeted throughout their arcuate portions, and curved wear plates inserted in and separately removable and relaceable relative to the rabbets of said memrs and adapted to receive sliding contact of said screen.
