My invention relates generally to improved means for stuffing upholstery pads or the like, the mechanism employed being somewhat the same as that disclosed in my co-pending application, Serial Number 665,735 filed April 12, 1933 covering Method of stulng pads.
The principal difference between the structure shown and described herein and that in my copending application is the mechanism employed for distending the unlled pad as to readily receive the filling nozzle, the main object of the invention being the employment of means to accelerate the mechanical pad stufling methods heretofore employed; another object is to eliminate certain parts of the mechanism heretofore deemed essential in automatic pad stuing equipment.
To more fully understand my invention, reference should be had to the accompanying drawings in which:
Fig. 1 is a side plan view of the mechanism employed, the parts shown being partially in section and partially fragmentary;
Fig. 2 is a longitudinal fragmentary sectional view of a pad mold: n
Fig. 3 is another fragmentary sectional view of a pad mold;
Fig. 4 is a fragmentary plan View of Vone of the rubber pad locking devices which forms a part of my invention;
Fig. 5 is a sectional view along the line 5 5 of Fig. 4;
Fig. 6 is a fragmentary plan view of the front of the mold;
Fig. 7 is a fragmentary view partially in plan and partially in section disclosing the mechanism for locking the mold and clamping a pad therein;
Fig. 8 is a fragmentary plan View of a plate having extended collars over which the different sections of an unlled pad are adapted to be tted;
Fig. 9 is a cross sectional View along the line 9-9 of Fig. 8;
Fig. 10 is a fragmentary front plan view of the carriage frame on which pads are fed to the stuiiing operators;
Fig. 11 is another fragmentary View partially in section and partially in plan of a pad mold; and
Fig. 12 is a top fragmentary plan view of a mold showing a portion of the cover broken away to reveal the pad in the process of being filled.
In the drawings the numeral I0 is used to (ci. 22e- 43),
designate a hopper from which stuffing is drawn into a blast fan II and from thence blown into chutes I2 and I3 alternately.
A valve I4 having its axis at I5 controls the dow of material from one chute to the other by manual adjustment by the stuffing operators so that the operation of pad stuffing is carried on continuously, there being no necessity of shutting oir the blast fan while one operator changes the loading nozzle from one section of a pad to another due to the fact that while one operato-r is filling one section of his pad, the operator of the other nozzle is adjusting his nozzle preparatory to filling asection in the pad before him. Therefore, a continuous ow of the material is preserved and such flow alternates between the nozzles. This portion of my invention is covered in Patent Number 1,828,673 granted October 20, 1931 and my other co'pending application filed since that time and for that reason it is not thought necessary or essential to discuss the said process in detail except as it pertains to the invention covered by the claims herein.
The numerals I6 and I'I are used to designate nozzles, the larger tubular ends of which are xed to the open ends of chutes I2 and I3. YThe said nozzles vI6 and I'I are reduced throughout a portion of their length, said reduction extending from approximately one-half the distance between the ends to the outer discharge ends thereof.
As illustrated in Figure 1, outlet elements in the form of tubes I8 are slidably tted over the nozzles I6 and II and are somewhat greater in length than the mold so that the same may be Y extended to the extreme inner portions of the pads within the mold for the discharge of filling material at such portions of the pads without, of course, becoming disconnected from the associated nozzles.
An emergency exhaust 20 is positioned between the fan II and the valve I4 so that when', for some reason or other, it is necessary to shut off both filling nozzles, an auxiliary means is afforded of diverting the stuffing as it comes from the blower. This auxiliary exhaust is usually connected back to the hopper so that in the 4 interim of total shut-off of the nozzle (which is accomplished by closing a valve 2| located directly ahead of the emergency exhaust orifice) stu'ing is by passed back into the hopper, thus preventing congestion of the stuffing immediately back of the valve 2l. The auxiliary exhaust valve, in addition to the stuffing diversion valve I4, is controlled by either of the two nozzle operators by means of ropes or levers.
A track frame, o-n which are mounted parallel spaced tracks 22 and 23, is positioned adjacent the orifices of the nozzles, the said tracks being so spaced as to permit the alignment of pad molds with the discharge orifices of the staggered parallel nozzles, one of the said nozzles being positioned to fill pads in molds riding on one track and the other to ll pads on the adjacent track.
To facilitate the travel of the molds along the track, the said molds are provided with flanged wheels 24, the said wheels being suspended from the under sides of the molds.
The mold per se, the construction of which is the essence of the invention herein described, has a solid bottom 25 and a perforated hinged top 26; the said perforated top is usually made of mesh wire which is aixed to a frame 27. The top and bottom members of the said mold are relatively adjustable through the medium of adjustable hinge members 29. The rear end of the said mold is also perforated and formed of a frame 30 to which a screen 3l is affixed.
Locking members 32 are provided, the said locking members being aixed to the hinged top of the said mold and the bottom end of the locking member is so formed as to cause the top to be locked to the base when the said hinged top is in closed position. These locking members are also adjustable so that the lock is operative at any adjustment of the height of the mold. The end opposite the hinged end ofthe mold, which we will hereafter designate as the front end, is open and the top and bottom members of the mold are spaced from each other through the medium of adjustable stop members 33.
A rubber friction member 34 extends across the front end of the hinged top on the underside thereof, and on the bottom of the said mold adjacent to and aligned with the top friction member is another rubber friction member 35. Both of the said members or yieldable pressure transmitting mediums consist of U-shaped metal frames in which a soft rubber strip is vuicanized. The lower friction member is adjustable relative to the top friction member through the medium of adjustable nuts and bolts 36. The function of the heretofore described friction members will be explained hereinafter.
A rectangular plate 31 closes the front of the mold when an empty pad to be lled is positioned therein. Said plate 31 has orifices 38, the edges of which are inturned to form collars 39; the said orifices are adapted to receive the telescopic sleeves I8 and I9 in the process of filling the pads. However, the dimensions ol the said orifices and the telescopic sleeves are determined by the size of the sleeves in the pad to be filled, the sleeves in the said pad being formed by sewing the said pad across its width as to form pockets for the stuffing to be blown into. It is also to be noted that the number of the orifices in the plate is determined by the number of sleeves sewn in the pad to be filled. Also the size and number of the orifices in the plate is determined by the size and number of sleeves in the pads to be lled.
The same applies to the filling nozzles. However, as the stuffing mechanism is principally designed for automobile pads where great quantities of similar size pads are to be stuifed, the sections in the pads are the same size and therefore only one set of plates is necessary. However. the mechanism is so designed as to permit the majority of it to be used when another size pad having more or less stuing and more or less sleeves formed in it is to be used, the amount of stuiling to be put in the pad being determined by the height of the mold, which invention is described and claimed in my Patent Number 1,828,673 granted October 20, 1931, heretofore mentioned.
The operation of my device is as follows:
Loading operators standing at adjacent ends of the track load and unload molds, the operation of loading being, in the instance of this invention, different from that disclosed in my copending application, Serial Number 665,735 filed April 12, 1933.
In the present invention, the operator rst slips the empty sections of a pad to be filled over the collars on the plate 3l; the assembled collar and section is then positioned in the mold, the bottom of the collars resting on the friction member 35 with the plate flush against the front edge of the bottom of the said mold. The hinged cover is then let down until the friction member 34 rests upon the upper edge of the collars. Slight pressure is placed on the hinged top which causes the locking members 32 (which have been properly adjusted) to lock the mold in closed position, whereupon the sections are xedly positioned on the various co1- lars of the mold and the opening in the said sections is distended as to permit entrance of the telescopic tube on the lling nozzle- The filling process is similar to that employed in my co-pending applications, namely, the loaded mold. is rolled to an operator who aligns the telescopic tube With the number I oriiice in the front plate. The said tube is pushed through the orice to the rear end of the section and when the adjacent operator diverts the flow of stung material to the rst-named operator, he slowly pulls the tube away from the rear end of the sleeve and, as explained in my co-pending applications, the pad lls up ahead of the said nozzle.
When the end of the tube approaches the front end of the mold, the operator diverts the flow to the adjacent operator who takes up the filling of another section of his pad, whereupon the rst named operator pulls the tube clear of the plate 3i' and moves the mold as to align orifice number 2.
By particular reference to Figures 7, 8 and 9, it will be seen that the form-giving collars 39 which surround the openings 38 and project into the mold serve not only as form-giving elements but as a means to align and guide the lling mediums or outlet elements I8 into position for lling the sections of the pad. Thus, the collars 39 serve the dual purpose of (l) aligning and guiding the filling mediums or outlet elements I8 with the sections of the pad and (2) giving the sections of the pad the required form.
It is not thought necessary to go into detail respecting the process of loading the pads and the feeding of the pads to the operators as it is fully explained in the aforementioned copending applications, the difference in the construction of this invention being in the mold and nozzles, the difference in the mold being the mechanism for distending the pad as to permit the entrance and exit of the filling nozzle without the necessity of employing tubes or other mechanical means for distending the sleeves in the pad to be lled. Thus fixed nozzles may be employed having telescopic tubes Which remain on the nozzles at all times.
Having described my invention, what I claim and desire to secure by Letters Patent is:
1. In a mechanism for filling the sections of pads with a filling material from a column of such material in suspension, a combined guiding and supporting member having a plurality of openings and form giving collars extending from and registering with said openings for the selective; detachable and temporary reception of a medium for the supply of illing material and constituting guides for the filling medium, means to clamp portions oi the sections to be filied about the said form giving collars preparatory to the detachable and temporary introduction and movement of said outlet element into and through said form giving collars and embodyingv yieldable pressure mediums engaging the sections of the pads, a pad mold having hingedly connected sections located at opposite sides of said pad, one of said sections of the mold being provided With a reticulated central portion for the passage of the suspension vehicle for the filling material, and a locking member holdingthe sections of the mold together and thus securing said yieldable pressure mediums in firm engagement with said sections of the pads.
2.
