.[ all whom it may concern:
Be it known that I, GEORGE R. WARD, a citizen of the United States,'residing at New York, N. Y., have invented certain new and useful Improvements in Pulp-Molding Ma chines, of which the following is a clear, full, and exact description.
My invention relates to a machine for forming articles from a suitable pulp; and my object is toimprove the construction of such machines.
My invention will be defined in the claims.
In the drawings showing the preferred embodiment of my invention, Figure 1 is a plan view; Fig. 2, a side elevation, parts being in section. Fig. 3 is a central sectional view; Fig. 3 a detail sectional view on line as as of Fig. 3. Fig. 4. is a partial section of a modification, parts being omitted; and Fig. is a section on line y y of Fig. 4.
In the above preferred embodiment, 1 is the base on which the parts are mounted, and 2 is a support extending therefrom.
3 is a traveling mold-face, preferably perforated, as shown. faceyl have in this embodiment provided a vertical shaft 4, which may be rotated intermittently or step by step by means of a roller.
5 on wheel 6, which roller enters slots in a star-wheel 7, fixed to the shaft, as shown in Figs. 1 and 2. low circular head 8, on which the mold-face 3 is carried by a hollow extension 9, communieating with both the circular head and the perforated mold-face.
In order to apply a layer of pulp to the mold-face, 1 preferably provide a stationary vat 10, containing a suitable pulp, as shown. In the present embodiment I have provided an auxiliary pulp-holder 11 in said vat, which normally stands below the level of the 'pulp in the vat and is raised up to said mold-face, as shown in dotted lines in Fig. 3, carrying with it a quantity of pulp. The mold-face enters the pulp-holder 11', as shown in dotted lines in Fig. 3.
13 is a hollow shaft at all times in communication with hollow head 8, as shown in Fig.
3, by which the air may be exhausted to produce a suction through the perforated moldpump 14 or other suitable device.
The auxiliary pulp-holder 11 is reciprocated by a plunger 15, carried on a sleeve 16,
In order to move this device 14.
The shaft 4 may carry a holhaving pins 17 thereon. A cam-wheel 18, fixed on the shaft 19, engages a roller 20 on lever 21 and rocks the same on pins 22, which lie in a slot in shaft 19, as shown in Fig. 2. The rock-lever 21 has two legs which cmbrace sleeve 16 and lie beneath pins 17, by which the sleeve and parts carried by it are raised to the proper height. The slotted wheel 7 then rotates the mold-face 3 a quarter-turn, and as 1 preferably provide on head 8 a number of mold-faces similar to the face 3 (four in the present embodiment) a new face is brought into the position shownin Fig. 2. A second mold-face 23, (shown in dotted lines in Fig. 2,) carried by sleeve 16, may be provided, which registers with mold-face 3 in its new position and by which the layer of pulp on the mold-face may be compressed to form the article at the same time that a layer of pulp is applied to the succeeding face. The sleeve 16 then sinks again, and the starwheel turns head 8 another quarter-turn, bringing face 3 into the position shown at the right of the figures.
24 represents spring-pressed valve-stems carrying valves to close or open communication between the mold-faces and the suction A 25 is a cam-ring attached to hollow shaft 13 for regulating the action of these valves.
26, Fig. 3, is a lever fixed to hollow shaft or pipe 13 and having a roller-stud 27 sliding in a cam-groove 28 in the lower face of a wheel 29, by which when. the face 3 arrives at the point shown at the left of the figures the camring 25 is slightly moved from right to left in Fig. 2 and depresses the valve at the left of the figure from the closed position shown to the open position shown in Fig. 3. T he valve remains open until just before the face reaches the position at the right of the figures, when the cut-away portion of the ring, Fig. 2, releases the stem and allows the valve to close.
30 30 are hollow pipes leading to and carried around. each of the perforated faces and which successively register with an opening 31 ,in an extension 32 from pipe 13 (see Fig. 3)
when the cam-ring is given the slight movement above described.
between pipes 13 and 32. This pipe 32 com municates with a compression-pump 33' or other suitable device, by'which a blast of air is blown through the mold-face and the 32 is a plug preventing communication formed article loosened from the mold-face or, if preferred, blown off from the mold-face. In Fig. 4 I have shown an alternative form of construction, the actuating mechanism being omitted." I have provided a reticulated mold-face 34, which may both supply the pulp to the mold-face 3, and also partially form the article, if preferred. .The plunger 36 may carry a reticulated basket 37 and may slide on a fixed tube 38, *com-' municating with the suction device 14. This pipe is closed by valve 39 until the finger 40 strikes the lower end of the valve-stem 41'as the plunger" rises, through basket 37 of the pipe) until after the basket or face has been. pressed against the face 3 and has moved downward away from the same to loosen or remove the articlefrom the moldface. This basket 37 therefore acts asa receiving-faee for the plate, and when said face is pressed against the pulp-dish on theface 3 thus applying suction I and suction is a plied through the receivingface 37 the dis will be removed from the face 3 withoutdamaging the dish. Faces 3 and 37 are shown as 'nestingwith each other, the face 37 being a counterpart of face 3.
' I am aware that many variations may be -made from the'constructionabove described without departing from 'thescope of my invention as claimed, and I therefore do not desire to belimited to the embodimentsherecause'said *faces '-,to 'bemoved together, one of 'saidfaces being perforated, and means to' ,causea'draft 0 air topass through-said perfora'ted'face when'said faces are in'contact,
