may be delivered singly or individually to a point of use as desired.
While the invention ilnds its principal application as a means for feeding paper cones, such as are used in textile industries, to a finishing machine or the like, it is not restricted thereto but may be employed in other relations wherein it is desired individually to advance conically shaped hollow articles from a stack thereof to a point of use. 'I'he organization is adapted for automatic operation.
An object of the present invention is the provision of an apparatus ofthe above-mentioned which shall function to hold the stack of cones while releasing the lowermost cone of the stack and positively disengaging the latter from -said stack and feeding the same to a point of use.
The above, and other, objects of invention are attained by an organization to be described in detail in the following description taken in conjunction with the appended drawing which illustrates a preferred embodiment of the apparatus forming the basis of the present invention.
Referring to the drawing: Figure 1 is a fragmentary side elevation of a cone feeding mechanism embodying the invention. Figure 2 is a sectional view of the mechanism taken on line C-C of Figure 1, showing the relative position of the plurality of latch fingers and snatch springs employed. Figure 3 is a vertical section on line l A-A of Figure 2, showing the position of the snatch springs with respect to a stack of cones; while'Figure 4 is a section on line B-B of Figure 2, showing the position and mode of operation of the latch fingers. In the drawing, like reference characters refer to like parts throughout the several views.
Broadly considered, the apparatus forming the basis of the present invention comprises a suitable chute for receiving nested cones, combined means for normally maintaining a nest of cones in one position with respect to the chute and for freeing the lowermost cone from the nest and delivering the so-freed cone, by gravity, to a point of use while maintaining the remaining cones of the nest in the normal position in the chute, and means for imparting operative movement to said combined means. In this assembly, the combined means may and preferably does include a latch means at least one portion of which extends through the wall of the chute and into engaging relation with at least the lowermost cone of the nest, said latch means, preferably an osclllatable latch pivoted to the chute, having on that portion of it which extends into the interior of the chute a lug having a shoulder, said portion being 5 characterized more specifically in that it includes a detent surface, the aforesaid lug, and a second detent surface constituting the shoulder surface of said lug.
The above-described latch means functions as follows: when the same is in normal" (i. e., nonoscillated) position its first-mentioned detent surfaceengages and supports the lowermost of the nest of cones and hence the whole nest. As the latch means is oscillated its lug engages the upper edge of the lowermost cone, exerting a downwardpressure thereon. At the same time, the oscillation brings the shoulder surface of said lug into supporting engagement withthe next to the lowermost cone. A v
The aforesaid latch means may be, and preferably is, pivotally attached to the exterior of said chute, there being provided in one portion of the latter at least one aperture through which the cone-engaging portion of the latch means extends.
For -insuringpositive release of the lowermost cone from the nest thereof and delivery of the same, by gravity, to a point of use, I may, and preferably do, provide on said operative movement-imparting means a snatch spring adapted to contact with the upper edge of the lowermost cone and to impart to the latter a positive downward pull. Where the said movement-imparting means "is located outside said chute, I provide an aperture in the wall of the latter through which a portion of said snatch spring extends in contacting relationship to the lowermost cone of the nest.
A specific apparatus embodying my invention preferably comprises, in combination, a. suitable housing i as the chute for the stack of cones to be disposed therein in substantially vertically nested arrangement and with theiry mouths upward, said housing providing therein an upper stack-retaining zone a, an intermediate cone-dispensing zone b and a lower cone-feeding or delivering zone c, and being apertured in its intermediate zone as at 2, 2, a cam collar 3 as the operative movement-imparting means aboutthe housing at said intermediate zone, said collarbeing vertically reciprocatable with respect to said housing and being provided with a beveled surface 4 at its top edge, means 5, 5 for vertically reciprocating said collar, a plurality of latch ngers 6, 6, pivotally mounted on the housing l as at l, 1, and a plurality of snatch springs 8, 8, mounted on said cam collar 8. t
The housing I may be, and preferably is, a cylindrical conduit of a diameter to freely confine a stack of cones; it may have any desired and suitable longitudinal dimension in its upper zone a and in its lowerzone c, and may be curved (as is indicated in the drawing in zone'c) to accommodate the apparatus to the whole organization of which it may be a part. As shown in the drawing it is pierced in its intermediate zone b by eight vertical slots or apertures diametrically in pairs, said slots to accommodate four snatch springs 8, 8, and four latch fingers 6,' 6. The snatch springs 9, 8, are mounted upon cam collar 3 in spaced relation 'by means of cap screws 8', 8'. These springs extendsubstantially vertically from the cam collar 3 for a convenient distance, their upper portions being inwardly inclined for entrance throughJ diametrically opposed slots 2, 2, into the interior of housing I and terminating in hooked ends 9, 9. The curvature of the upper portions of snatch spring 8, 8, is such, and their hooked ends 9, 8, are of such relative shape and size, that they may be advanced or slid over the outer surface of a cone and over the upper edge thereof by upward movement of cam collar 3 but will insure that said hooked ends 9, 9, positively engage the upper edge of such cone and exert a downward pull thereon when the cam collar 3 is moved downwardly.
The latch fingers 6, 6, (here shown as being four in number) which are pivotally mounted at their upper ends as by pivots 1, 'Lin diametrically opposed slots 2, 2, of housing Il in spaced relation, present inner surfaces which in their lowermost portions are substantially plane and which, in the normal position of the latch fingers, are substantially parallel with but spaced from the outer -wall of housing I, but which are inwardly curved as at I6, I0, intermediate the ends of said elements to cooperate with and receive actuation from cam collar 3. 'At their upper ends they terminate in beveled surfaces II, II, constituting detent surfaces. At the outer and up'- per ends of said beveled surfaces II, II, are lugs I2l I2, whose shoulder surfaces I3, I3, aresubstantially plane and constitute further detent The bevel of surfaces II, II, is such' surfaces. that when the latch fingers 6, 6, are in substantially vertical (i. e., normal) position, surfaces II, I I contact with and engage the upper portion of the lowermost cone of the stack thereof. The bevel` of lug surfaces I3, I3, is such that said surfaces may contact and engage the next to the lowermost cone ofthe stack when latch fingers 6, 6, are moved to the 6', 6', position by cam collar 3. Y
Cam collar 3 is vertically reciprooated, through pivoted links E, 5, being actuated from any suitable reciprocating means (not shown) timed as to motion to accommodate a desired operation of the entire organization of which the present apparatus maybe a part. The curvature of the curved surface l at the` upper end of cam collar 3 is such that the said cam collar, in its upward movement, can oscillate the latch ngers 6, 6,
linwardly and downwardly whereby to cause the lugs I2, I2 to engage the upper edge of the lowera downward pressure thereon simultaneously moved detent surfaces ii, ii, out of engagement with the lowermost cone and presenting shoulder surfaces I3, I3, for engagement with 5 the next higher cone of the stack whereby to retain the same, and hence the stack of cones, in the intermediate zone b of said housing.
In operation, a stack of nested cones is placed in the upper zone a of housing I, the lowermost 10 cone resting on surfaces II, II, of latch fingers 6, 6, and pivoted links 6, 5, are caused to move the cam collar 3 upwardly and downwardly over a portion of intermediate zone b oi housing I. With each upward movement od the cam collar l5 the latch ngers 6, 6, are moved to position 6', 6', thereby releasing the lowermost cone of the stack.' engaging the upper position of the next lowermost cone and exerting a downward pressure on the upperedge of the lowermost cone; simul- 2o taneously the upward movement of cam collar 3 slides the hooked ends 9, 9, of snatch springs 8, 8, upwardly over the upper edge of the lowermost cone where,'by virtue of the inclination of said springs, the said hooked ends engage the upper 25 edge of said lowermost cone. With downward movement of cam collar 3 the snatch springs 8, 8,
exert a downward pull upon the engaged edge of the lowermost cone, moving the same downwardly out of intermediate zone b and into the 30 delivering zone c through which it may descend by gravity: simultaneously, as cam collar 3 is downwardly moved over curved surfaces I0, I!! of latch ngers 6,- 6, the latter are allowed to return to their so-called normal position, thereby dis- 35 engaging shoulder surfaces- I3, I3 from supporting contact with the now lowermost cone of the stack and engaging the detent surfaces II, II with the said cone whereby to hold the same,
and hence the stack of cones, from moving out 40 of intermediate zone b.
-mensions, and shapes, of thecooperating elements of this device will be determined at least in part by the size and type of cones to -he handled thereby, and that a greater or lesser 55 number of latch iingers and/or of snatch springs may be employed, depending likewise upon the size and type of articles to be dispensed.
