MACHINE FOR MAKING AND LAYING CONCRETE PIPE.
Specification of Letters Patent.
Patented A r. 8,1913.
Application filed December 9, 1911. Serial No. 664,811.
My invention relates to apparatus for making and laying concrete pipe in trenches, and more particularly to an apparatus for making and laying continuous pipe for irrigation purposes.
The object of the invention is to provide a hand-power machine for the purpose that shall be simple and light in construction, and efficient in operation. In accomplishing this object, I have provided the improved details of structure, which will presently be fully described and pointed out in the claim, reference-being had to the accompanying drawings, in which:
Figure I is a side elevation partly in section of a machine embodying the invention. Fig. II is a plan view thereof. Fig. III is a detail view partly 'in section on line aa of Fig. V, omitting the oil box. Fig. IV is a detail view of one of the shaft bearings. Fig. V is a detail view of a part of the gearing.
Referring more in detail to the parts the frame of the machine is designed for use in a narrow trench, and comprises a pair of horizontal runners 1, two upright members 2, and a pair of inclined braces or stays 3, connecting the top of the former with the forward end of the latter. These parts I prefer to make of light fiat metal bars.
Attached to the frame parts 2 by straps 4 is the receiving chute 5 for the previously mixed material. Said chute is curved rearwardly at its lower end and connects with a forming tube 6; the bore of which is that of the size pipe to be formed. The bottom of this tube is at substantially the level of the bottoms of the runners 1, which at their forward ends rest upon the ground. The forward end of the frame is supported by a single centrally disposed carrying-wheel, 7.
A shaft 8 is axially disposed in the forming tube 6 and is passed through a bearing 9 in the connecting bend and extended to the forward end of theframe, close to the wheels 7 at which point it has a bearing 10. Fixed on the opposite end of said shaft is the mandrel, l2. Mounted rotatably on shaft 8 is a tubular shaft 14 that extends from the mandrel 12 to a point shown on Fig. I. Fixedly mounted on this shaft is the feeding or forcing worm 15. Abutting the end of the worm shaft 14 is a bevel gear wheel 16, loose on shaft 8. The hub of this wheel is drivingly connected with the worm shaft 14 as shown at 17 in Fig. V. Keyed on shaft 8, facing gear 16, is a bevel gear wheel 18, and a drive pinion 19 meshes constantly with both. Pinion 19 is on a vertical shaft 20 which has bearings in suitable castings 21, and has on its upper end a bevel gear wheel 22, meshing with a bevel gear wheel 28 on a transverse shaft 24, on which is a hand crank 25.
In Fig. V, 26 designates an oil box in which the gears 16, 18 may run, they in turn lubricating the teeth of pinion 19. The upper ends of frame pieces 3 are connected by a handle 27, by which the machine may be lowered into a trench and raised therefrom. Supposing the machine to be positioned in a trench, one man feeds the mixed and wetted material into the chute 5. The other operator straddles the trench and turns the crank 25, steadying the machine by its handle 27. The tubular shaft 14 will be driven in one direction, causing the worm 15 to force the. material out around the mandrel 12. The shaft 8 being driven in the opposite direction to that of the worm shaft, the mandrel itself will be rotated thereby, and thereby neutralize any twisting effect the worm might otherwise have on the pipe. As the pipe emerges from the tube the reactionby the worm 15 thereon drives the whole apparatus forward, the ends of the runners 1 sliding along the trenchs bottom. It is obvious that the operation will be continuous as long as the machine is kept supplied with material and the driving crank operated.
Having thus described my invention, what I claim as new therein and desire to secure byv Letters-Patent is In a machine of the type described, a frame comprising uprights and runners, a forming tube having an upturned receiving end attached to said uprights, a tubular shaft journaled on said tube and having a worm on its inclosed portion, a mandrel shaft extending through the tubular shaft and projecting from the inclosed end thereof, a mandrel on the projecting end of the mandrel shaft gears on said shafts, a vertical shaft mounted in the uprights, gearsv on the vertical shaft engaging the gears on 10 the tubular and mandrel shafts whereby the last named shafts are revolved in opposite direction when the vertical shaft is revolved, and means for actuating the vertical shaft.
In testimony whereof I afiix my signature in presence of two witnesses.
GEORGE STUMP.
