APPARATUS FOR MANUFACTURING TOILET-PINS.
Be it known that I,'MAXWELL VIDAVER, a citizen of the United States,and a resident of New York, in the county of New- Yo-rk and State of New York, have invented certain new and useful Improvements in Apparatus for Manufacturing Toilet-Pins, of which the following is a specification."
- The present invention relates to improvements in an apparatus for manufacturing toilet-pins. Y i
Toilet-pins usually comprise each a short, stiff piece of wire, with a sharp point and a round, substantially spherical head, the latter being made of vitreous or similar material. In manufacturing these pins, wire is first cut into pieces ofthe requiredlength, the blanks so formed being then pointed and thereafter the blunt ends of the pins dipped into-a vitreous mass tojproduce the heads. The finished product is then usually mounted uponcard-board cubes, into each face of the cube being stuck a predetermined number of pins, so that only their heads are visible. I
' The main obj ect'of' the present invention is to provide a simple andinexpensive apparatus, by means of which the pointed pin blanks are evenly distributed in spaced relation upon and clamped -to a frame, preparatory to their blunt ends being dipped to form heads thereon, saidframe serving also to mount the pins on the paste-board cubes, as above specified. A y
1 With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists-in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes maybe made in the size and proportion of the several parts and details of construction within the scopeof the appended claims without departing from' the spirit or sacrificing any of the advantages of the invention. 7 One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a top plan view, partly in Specification of Letters Patent.
2is a-front elevation--thereof,-partly in sec tion, on a larger scale; Fig.3 isfanendview I Patented state-21, 1'92o'. Application filed August 1, 1919. Serial "No. 314,603. A R
of the 'same; Fig. 4': is a section taken on line 4+4 of Fig. 2; Fig. 5 is a top plan View, partly in section, of one. of i the clamping frames of the apparatus; Fig. 6 isLa diagram showing the, method ofj'mounting the finished pins on apaste-board-cube; and
Fig. 7 is aperspective view of a cube with the pins mounted thereon. In the. drawings, the numeral 10 indicates a base-plate, from which rise side frame sections 11. In these frame sections are formed registering, .vertically extending slots 12, through which extend lugs 13 on a hopper 14:. This hopper is made in. the
form of an oblong receptacle, which is divided by a plurality of longitudinal partitions' 15 and transverse "partitions 16 into a number of -compartments.- Inthe case illustrated in the drawings, there are eight compartments in each transverse. row,
lengthwise each row-there being ainul- L tiple of eight, for": a: purpose which: will hereinafter: appear. The bottom 17 of the hopper is of 'a subs'tantialthickness, and is provided with apertures 18,. each of which is of a ,diametenthatis somewhat larger than the pin blanks to :be distributed;
Within each compartment, of .the hopper there are formed; in the said bottom four apertures, thej-entirenumber of apertures in said'bottom being. distributed SHbStLtn-w tially equidistantly, and disposed in rows that extend both lengthwise and also-transversely of the hopper, thatis to say parallel to the longitudinal artitions and also to the transverse partitlons above mentioned.
The hopper is given a reciprocating or vibratingmovement by a suitable mechanism,including-in the present case bars 19,
bly mounted'invbea'rings on the side frames Ilarid provided with. a crank 23. g The slots 12, in cooperation with thelugs 13, serveas guides for the hopper, which receives," by
' clamping inafter. "Springs 14, attached to the T1013". per and guides 20, serve tohold the bars 19 in engagement with the star-wheels.
A substantial distance below'the hopper.
there is formed upon the inner face of each side frame a horizontal ledge 24, said ledges .being adapted to support a plate member 25, upon whichare adapted'to rest clamping frames 26. The plate member 25, when on" the said ledges, abuts against stops 27, mounted upon therear faces of the side frames, said-stops projecting inwardly, as clearly shown in Fig. 1 of the drawings. In alinement with these stops the rear longitudinal edge-of the plate member is provided with :an upwardly extending flange 28, against-which the frames 26 areadapted to abut. The frames extend each throughout the width of the hopper 14, and are square in configuration, as appears from the. drawings. When upon the plate member 25, the frames 26 are properly spaced apart by transverse ridges '29, that project downward from the underface of the hopper bottom. e
Each of the clamping frames 26- comprises two sidewalls 30 and two end walls 31, said end walls being connected by tie-bars 32, disposed parallel to the side walls 30. 0 these tie-bars are fixed the stationary jaws 33 of the clamping frame, said jaws being made each in theform of a strip and extending all-inparallel relation to the end walls 31 of the clamping frame throughout the length thereof. With each stationaryjaw cooperates a movable jaw 34, also in the form. of a strip, said movable jaws being slid'ably-moun'ted upon the tie-bars. For simultan'eouslyactuatingthe movable jaws,
there are two screw-threaded spindles 35 rotatably mounted in the endwalls31 of the frame, said spindles passing through screw-threaded holes 36 in,the movable jaws and through holes 3-7 in the staq tionaryjaws. The holes 37 are each of a diameter that is larger than the diameter of 'a spindle 35.
The "stationary jaws of the clamping frames are substantially in alinement with the longitudinal partitions 15 in the hopper, so that pins passing through the apertures 18in the hopper bottom abut against the said stationary jaws to be clamped thereagainst by the movable jaws, when the latter are moved toward the stationary jaws by m tating the screw-threaded spindles 35 in the proper direction. Each of these spindles is provided with a handle 38, by which it may be grasped. i
he jaws of the clamping frames are each of a height that is substantially less than the height of the walls of the said frames, the
lower edges of the said jaws being flush with the lower edges of thesaid frames, as clearly appears from Figs. 2 and 6 of the drawings. Above the jaws each frame is divided by a longitudinal partition 39 and a transverse partition 40 into four equal sections, into each of which fits, as will hereinafter appear, a paste-board cube 41, that is to"receive the finished product (Fig. 6).. The
clamping frames rest on upwardly projecting ledges 25 on the plate m'ember25.
The plate member 25 and the clamping frames resting thereon may be raised from the ledges 24 into contact with the hopper crank 44. Hooks 45 pivoted to the hopper and in engagement with pins 46 on the plate member 25 serve for detachably fastening the plate member 25 with the clamping frames thereon to the hopper (Figs. 2 and 4.) I 7 The operation of this device is as follows :-The pointed pinsvare placed loosely in upright positions into the compartments of the hopper with their blunt ends resting on the hopper bottom.- The; clampingframes, with their jaws in open position, are placed upon the plate member 25, and the latterraised by the cams 43 by shifting the crank 44 in the proper direction. The hooks 45 are then engaged with the .pins 46, to fix the clamping frames and; plate member to the hopper. The crank 23 is then turned in theldirection of the arrow Shown in Fig. 3 of the drawings, whereby a vibrating or reciprocating motion is imparted. to the hopper and the elements fixed. thereto. By this vibrating motion,.pins are caused to pass into the apertures 18 in the hopper bottom, said pins resting with their. blunt ends on the plate member 25 between sets of stationary and movable: jaws on vthe clamping frames. It. is to be observed that into each aperture 18 only one .pin is admit.
ted, those remaining in the compartments of the hopper not interfering with those resting on the plate member 25. After the hopper has been vibrated for the required time, the screwthreaded spindles 35 on the clamping frames are turned. clockwise, whereby the movable jaws are shifted toward-the-stationary jaws intogripping positions, thereby clamping the pins to the frames 26. V
In order to allow the clamping franies to be removed from the apparatus, it becomes necessary to lower the same together with the plate member 25. For this purpose the hooksz45 are first disengaged from the pins efiand then thecrank' 4.4: shifted in the direction. of thearrow shown in-Fig. 4 of the drawings When the clamping frames are in their lower positions, the pointed ends of the pins clamped thereto clear the hopper bottom.
The clamping frames are then one-after the other removed from the apparatus, andthe blunt ends of the pins, which project below the said frames, dipped into a, 'prefthe pins may be Withdrawn from the frames by lifting the cubes, the heads of the pins passing between the jaws, which are, in their open positions, disposed at a distance from each other that is somewhat larger than the heads of the pins. After having been disengaged from the frames, the pins are forced into the cubes throughout their lengths by placing the said pins on a table or similar support, and pressing the cubes downward toward the said support. After one face of a cube has been finished, the operation now described is repeated with the next face thereof, and so on.
It is to be observed that the blunt ends of the pins, before being clamped to the frames, are kept by the plate member 25 in the same plane regardless of the lengths of the pins. In this manner, when the pins are being dipped, they will each receive a head of the'same size.
Attention is also called to the fact that the pins are each of a length that they remain, during the vibrating motion of the hopper and frames, partly in the apertures in the hopper bottom. For this reason a single pin only can be fed through each aperture.
It is obvious that, while herein the apparatus has been described as containing a specific number of compartments in the hopper and each compartment having a specified number of apertures in its bottom portion, any other suitable arrangement may be made without departing from the invention, which lies mainly in the provision of a pin distributing hopper, in combination with a clamping frame, that so holds the pins that their blunt ends are adapted to be dipped for the purpose specified.
It is to be noted also that, while herein a particular means has been described for imparting a vibrating or reciprocating motion to thehopper-and the elements fixedthereto, and a specific means. has been disclosed for clamping the distributedqpins to frame,
any other construction maybe used within 7 the scope of the-appended claims.
