The cover Fis shown as supported by upper corner brackets G carried by the main section of the cabinet. Adjacent to one end, it is provided with an opening F, preferably of generally triangular outline, which is adapted to register with the opening in the seat thereabove, the said opening F being surrounded by a downwardly projecting flange, the front. wall F of which is shown as substantially parallel with the front wall A of the cabinet and the walls F of which converge rearwardly.
The bowl shown herein comprises a downwardly and rearwardly inclined bottom l0, generally triangular in form, with its widened end at the front, and rearwardly convergent side walls ll extending upwardly from each side of the bottom, the bowl being supported at its front end from hangers l2 having their upper ends flanged and secured to and beneath the overhanging flanges of the side walls A and A The rear ends of the side walls of the bowl are preferably secured to the cross member C", as by ears Ila.
I3 denotes a rollof moisture-proof paper, the core l4 of said roll being supported in slots I2a in the hangers I2. This paper constitutes a conveyor for fecal matter deposited thereon above the bottom of the bowl. l5 denotes a roller located above and in front of the front end of the bowl over which the paper conveyor passes.
The flushing and tube-forming mechanism I comprises a plurality of reciprocable parts which are carried by a frame supported in the rear portion of the cabinet section AA The frame which supports said mechanism comprises a front transverse angle member l6 which is fastened to the cross member C", as by screws H, a rear transverse angle member l8 which is supported by ears C extending from the transverse member C at the rear of the maincabinet section. The transverse members l6vand [8 are also connected by marginal side members l9 and 20. Ears l6 and Ill dependingfrom the ends of the downwardly extending flanges of the angle. members l6 and I 8 are provided withopenings for the reception of guide rods 2| and 22 which are arranged equidistantly from, and parallel with the longitudinal center of the frame. The marginal side member I9 is also provided with hangers 23 which support a ratchet bar 24 having wide and deep notches 25 at opposite endsthereof and narrower intermediate notches 26. The frame thusdescribed supports the movable parts of the flushing and tube-forming mechanism to which reference has been made hereinbefore.
Projecting from the rear member iii of the frameworkare bracket membersZl, 2! and 28. slidably mounted in the bracket members, 21 is a plunger 29 having at one end a cross pin 30, the opposite end of said plunger cooperating with a pad 3| carried by the bracket member 28, for
a purpose to be described hereinafter.
M denotes a spring surrounding the plunger 29 and hearing at one end against the bracket member 2'! and at its opposite end against a pin 33 carried by the plunger, whereby the spring tends to move the end of the plunger mounted in the bracket 2! into engagement with the pad 3|. The end of the plunger 29 which projects through the bracket member 21 rides within a slotv 35.
provided in a cam block 34, the cross pin being adapted to ride along the cam surfaces 34 of said block. This cam block is mounted on the rear end of the rod 36, the opposite end of the rod being slidably mounted in a part of the frame structure of the flushing and tube-forming mechanism, which will now be described.
Flushing and tube-forming mechanism The flushing and tube-forming mechanism comprises generally a supporting framework slidably mounted on the rods 2! and 22; a pair of vertical spindles supported by said framework; sealing rollers mounted on the upper portions of said spindles; tube-gripping members mounted on the lower portions of said spindles; pinions on the upper ends of said spindles; a double rack carried by the first mentioned frame on the centerline thereof and engaging said pinions and operating to rotate the latter as the flushing and tube-forming mechanism is moved to and fro along said frame; a one-way driving connection between each pinion and its spindle; a discharge spout carried by and extending rearwardly from the framework of said mechanism; guide members secured to the front end of the framework for the purpose of assisting in shaping the paper conveyor into tubular form; and means for reciprocating the said mechanism.
The framework for the flushing and tubeformingmechani'sm is indicated generally at H, and is preferably a casting having a bottom 31, approximately rectangular in outline, vertical front corner posts 38, vertical rear corner posts 39, and upper side members 40 connecting the op posed front and rear corner posts. The front corner posts are provided each with a forwardly extending projection 38 the inner faces 33' of the said projections being rearwardly convergent, for a purpose to be described. To the rear corner posts, there is bolted 'or otherwise suitably secured, a spout 4| which is preferably elliptical in section, said spout being provided with a longitudinal slot 42 in the top thereof located in a vertical plane extending through the longitudinal center of the frame l6i8 and through the longitudinal center of the framework H. The spout is also provided at its front end with lugs 43 by which it may be bolted to the rear corner posts. The inner edges of the rear corner posts are preferably rounded to enable each to form in effect a continuation of the front of the adjacent rounded inner wall of the spout. Theside members 40 of the framework H are provided with projecting ears 40* having apertures therethrough whereby the framework is slidably mounted upon the rods 2| and 22. The front end of the rod 36 is slidably mounted in a flange 44 carried by one of the rear corner posts 39.
45 denotes a pair of vertical spindles arranged equidistantly from the center line of the framework H and each having its lower end rotatably supported in a ball bearing 46 carried by the bottom member 3! of the said framework and its upper end rotatably mounted in a ball bearing 41 carried by a cover plate 48 which is secured to the tops of the corner posts, as by screws 49. Each of these spindles is shown as provided with an upper disk 58 and a lower disk 5 I, rigid therewith, the said disks being located below the tops of the spindles and the disks on each spindle being provided withtwo sets of vertically aligned openings, one set 52 being located closely adjacent to the spindle and the other set 53 being located adjacent to the peripheral portions of said'disks. In the former pairs of aligned openings there are mounted pins 54 each surrounded by a spring 55 which normally project the upper ends of the pins above the tops of the disks 50. The pins 55 are mounted in the other pairs of vertically aligned openings 53, each being surrounded by a spring 51 which normally projects the upper ends of the pins above the tops of the disks 50.
58 denotes arms mounted respectively in slots 59 formed in the upper ends of the side members 40 of the framework H. Each of these arms is provided with a cam 58 on the under surface thereof, and the inner ends of these arms are so located as to enable the cams to ride over and depress the pins 56 when the spindles are operated in the manner to be described hereinafter. Mounted on each spindle 45, between the upper disk 5|] and the ball bearing 41 thereon, is the hub 6| of a pinion 60, each of said hubs being loosely mounted on their respective spindles. Each pinion is provided on its under surface with a cam 62 which is adapted to ride over the top of the pin 54 therebeneath when the said pinion is rotated in one direction by its engagement with the teeth on one side of a double rack 63 which is supported above the center line of the framework H by the front and rear members l6 and l 8 of the frame on which the flushing mechanism is mounted.
The spindles 45 each support a tube-gripping member, the said members being adapted to engage the opposite sides of the front end of the tube formed within the spout 4| and to substantially close the front end of the tube and to carry the tube and the contents thereof into the receptacle C by the delivery movement of the flushing mechanism, which movement also serves to draw another increment of the conveyor paper from the roll I3 across the bowl to replace that removed by said delivering movement. Each of the gripping members is preferably in the form of a vertical metallic blade 64 having the central portion thereof recessed to provide a seat for a pad 55, adapted to frictionally engage one side of the paper tube. The material which I have found suitable for such pads is sponge rubber. The gripping members are slidably mounted in their respective spindles by pins 66, springs 13! surrounding the said pins and, when the gripping members are in operative relation to the paper tube, yieldingly pressing the said gripping members toward each other and in engagement with the said tube. It will be noted that the bottoms of the gripping members are spaced a short distance above the bottom 31 of the framework H. The purpose of this spacing will be explained hereinafter in connection with a description of the complete operation of the apparatus.
When the parts of the flushing mechanism are in the operative positions shown in Figs. 5 and 6, the paper of which the conveyor is formed will extend upwardly between the gripping members and between rollers having their upper ends surrounding the disks 50 and their lower ends supported by annular flanges 5| on the bottoms of the disks 5|. Each of these rollers comprises a cylindrical base 68', preferably of metal, said base supporting a cylindrical covering 69 of yieldable friction material, preferably sponge rubber.
Pivoted to the outer side of one of the side members .40 of the framework H is a pawl 10, the said pawl beingprovided with a weight-arm H which tends to swing the nose of the pawl downwardly.
Pivotally mounted on the front posts 38 of the said framework and constituting in effect rearwardly convergent extensions of the rearwardly convergent front surfaces 38 of said posts, are inverted U-shaped guides J, preferably of sheet metal, which receive the upper edges of the opposite sides of the paper conveyor extending rearwardly across the bowl and cooperate in ensuring the delivery of. the conveyor to the flushing and tube forming mechanism in a shape which will enable the latter readily to complete the formation of theconveyor into a tube.
12 denotes a seat which is pivoted to be swung backwardly against the cover A, when the latter is in the position shown in Fig. 2, and to be swung downwardly inoperative relation to the flanged opening provided in the front end of the cover F. 13 denotes a stud secured to the cover plate 48 and extending through a longitudinallyextending slot .14 provided in the cover F, said stud having an operating handle 15 on its upper end.
With the parts constructed and arranged as described, the operation will be as follows: When it is desired to flush the bowl, the operator grasps the handle 15 preliminarily to moving the flushing and tube-forming mechanism rearward 1y. At this time, the gripping members 65, 65 are in engagement with opposite sides of the conveyor paper l3 and hold them in engagement with each other. As the handle is moved rearwardly the gripping members not only hold the opposite sides of the conveyor paper together but pull the conveyor paper from the roll l3 and across the bowl. During this movement, the pinions 50 are revolved by engagement with the teeth on the rack 63 but turn idly on the tops of their respective spindles, it being noted that the number and spacing of the teeth on the pinions and rack are such that the pinions are each given a complete revolution by a full stroke of the framework H and spout 4|. The cams 62, during the revolutions of the pinions imparted thereto by this rearward or delivery stroke, travel away from the pins 54 and, at the end of the stroke, will have made a complete revolution, and the pins will have ridden under the cams 62 and have assumed the positions shown in Fig. '7. As the cams ride over the pins 54, any tendency to rotate the spindles, due to the frictional drag between the cams and the tops of the pins 54 and the pull of the paper, will be prevented by the engagement of the shoulders of the cam bars 58 with the pins 56. As the spindles are not rotated during this movement, the rolls 68, 69 do not rotate, but travel, without turning,'at the same rate of speed as the upper edges of the paper conveyor tube therebetween. This operation causes the spout to enter the receptacle C. Also, at the end of this stroke, the base 34 of the cam block 34 is engaged by the flange 44 on the adjacent rear post 39 of the framework H, thereby moving the cam block rearwardly, whereupon the cross pin 30 slides down the cam surfaces 34 and the spring 32 projects the plunger 29 toward the pad 3|, the plunger and pad serving to grip the top edges of the conveyor tube therebetween and in line with the slot in the top of the spout 4|, thereby to retain the tube against longitudinal movement during the return stroke of the flushing mechanism.
During the return stroke of the flushing mech- 75 anism, the upper edge of they conveyor'tube is held between the plunger and the pad, retaining in the receptacle C the portion of the conveyor tube and the contents thereof that were formerly in said spout. During this same stroke, the pinions 60 are each rotated by the rack 63 in the reverse direction from that which was imparted thereto by the delivery or. flushing stroke. At the start of this return stroke, the backs of the cams 62 engage the pins 54 and ro-. tate the spindles, which results in rotating the rollers 68, B9 in sealing engagement with the upper edges of the tube in front of the spout 4| and in sealing such edges, it being noted that the conveyor paper- I3 is not only moisture-proof but is preferably coated with latex, or similar adhesive material, along its upper edges, which material will enable these edges to adhere to each other under pressure but will not adhere to surfaces which are not similarly coated. In fact, I have found it practicable to employ a coating of latex for the entire refuse-receiving surface of the conveyor paper which is Wound upon the roll, the latex serving notonly to make the paper moisture-proof, but also enabling the upper edges to be sealed togetherinto tubular form by the action of the rollers 68, 69 and the conveyor tube to be formed into compartments by the engagement of the gripping members with opposite sides thereof. The rollers E8, 59, being of greater diameter than the diameter of the respective pinions thereabove, would exert a pull upon the paper during the return stroke of the flushing mechanism. This is avoided by mounting the rollers in the manner shown herein, whereby they are capable of slipping upon their respective disks 5B and EN. The rotation imparted to the spindles by the return stroke of the flushing and tube-forming mechanism also moves the gripping members 65, 85 away from the conveyor tube. At the end of the return stroke, the cams 62 are still'back of their pins 54, in position to be moved away from them at the next flushing operation, and the gripping members have been brought around to the positions shown in Fig. 6; the pins 56 also will have passed under the cams 58 and will have assumed the positions shown in Fig. 7. As the flushing and tube forming mechanism'nears the end of its return stroke, the flange 44 engages the head ofthe rod 36, moving the cam block 34 forwardly until, at the end of said stroke, the parts will be in the position shown in Fig. 9, with the end of the plunger 29 and the pad 3| out of gripping engagement with the top edges of the conveyor tube.
Due to the pawland-ratchet shown and described herein, the operator is compelled, once he starts to move the flushing mechanism in either direction, to complete the full stroke thereof. This is due to the engagement of the nose of the pawl with the intermediate recesses 26 during such strokes, the pawl being incapable of reversal until the flushing mechanism shall have made a complete stroke in either direction, at the ends of which strokes the pawl will be in one or the other of the wide and deep slots 25 in the ends of the ratchet bar 24, which will enable the pawl to be reversed and permit the flushing mechanism to be moved in the opposite direction.
Reference has been made heretofore to the fact that the bottoms of the gripping members 65, 65 are spaced above the bottom of the plate 31 of the frame H. This is for the purpose of allowing a channel for urine or other liquid to be formed in the bottom of the portion of the tubular pocket within the spout.
With the parts made in substantial accordance with the relative dimensions shown herein, two reciprocations of the flushing mechanism will be required to effect the complete removal and renewal of the pocket receiving portion of the conveyor.
With an apparatus constructed and operated in the manner shown and described herein, and with the use of a suitable adhesive for the waterproofing material applied to the conveyor paper, each operation of the flushing mechanism will result in forming into a tubular pocket a portion of the conveyor paper which has previously extended across and been supported by the bottom of the bowl, or trough-like support, together with the material deposited thereon; in sealing the top of such tubular pocket; and in substantially closing off the front or receiving end of said tubular pocket from the bowl and the seat. Where the upper surface of the paper is completely coated with such adhesive material, successive operations will deliver into the receptacle C a continuous its contents may be removed and the contents disposed of in any sanitary manner.
In Fig. 12, there is shown a construction of spout which serves to effect a temporary seal between the top edges of the conveyor paper, without the necessity for applying adhesive to the upper edges nor, in fact, without the necessity for using for the conveyor any paper other than moisture-proof paper of sufficient strength for the purposes desired. In this View, [6 denotes a spout which is of the same general form as the spout 4i and which is provided at its front with lugs Tl by which it may be bolted to the rear posts of the framework H in the same manner as is the case with the spout 4|. A centrally arranged slot through which the upper edges of the conveyor paper I3 extends is provided by a longitudinal channel 18 formed within a rib 19 on the top of one of the sides of the spout and the adjacent inwardly projected edge of the top of the other side. The parts 18, i9 and 8t serve to form a U-shaped bend in, and a temporary seal or closure for, the tubular conveyor paper. In view of the fact that the tubular seal is effected by the spout itself, the sealing rollers may be dispensed with.
From the foregoing description and illustration, it will be evident that I have produced a portable drytoilet which is capable of handling and disposing of feces conveniently and in a completely sanitary manner and which is capable of use wherever lack of sewage facilities may occur.
