TAIVIALE-IVTAKING APPARATUS.

Application filed February 1, 1922. Serial No. 533,289.

To all whom it may concern:

Be itknown that I, AMANno M. OJEDiA, a citizen of Mexico, residing at Los Angeles, in the county of llos Angelcs and State of California, have invented new and useful Improvements in Tamale-Making Apparatus, of which the following is a specification.

My invention relates to apparatus for making tamales, and a purpose of my inventlon is the provision or an apparatus of this character in which mechanism is provided lli for successively feeding corn husks to the discharge end of a magazine from which s fOPClblY fed the material of which a tamale is formed, and means associated with the magazine for spreading the material over the surface of the corn husks. Furthermore, my invention provides an. apparatus which deliversthe material and husk to a remote point for a subsequent folding of the husk in completing the making of the tamales.

I will describe one form of tam ale making apparatus embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings,

Figure l is a view showing in side elevation one form of tamale malnng apparatus embodying my invention.

Figure 2 is an end elevation of the apparatus shown in Figure l.

Figure 3 is an enlarged view partly in vertical section of the magazine and adjacent mechanism.

3 Figure 4 is a vertical sectional view taken on the line 4t-4 of Figure 3. a

Figure 5is an enlarged fragmentary view showing the magazine and husk i'ceding mechanism in front elevation.

Similar reference characters refer to similar parts in each of the several views.

Referring specifically to the drawings, my invention in its present embodiment comprises a table designated at T and including legs 15 for supporting the table top 16 in the desired horizontal plane. T he legs are the bolts are adjustable vertically within the slots 19 to vary the horizontal position of the bars 21 and consequently the bracket 22. Within the bracket 22, a magazine M is adapted to be sustained, the latter in the present instance being of cylindrical form and having its upper end closed by a convex cover plate 23 detachably secured by means'oi? pivoted securing members 24.

' As shown in Figure 3, the" lower end of the magazine M is formed with a tapered spout 25 through which the material forming the tamale is adapted to be discharged. The discharge of the material from the spent 25 can be regulated by means of a shutter 26 slidably fitted on the track 27 formed on the spout, and adjustable by means of a nut 27 threadedly fitted on the bolt 28 riveted to the spout 25, and grooved to receive a pair of ears 26 formed on the shutter 26. In ei'lecting a spreading of the material over the huslrs after its discharge from the spout 25, I provide a presser plate 29 formed with a forwardly curved lowerend having a concave edge as clearly shown in Figure 5. The upper end of the plate 29 is slotted as indicated at 30 to receive a threaded stud 31 carrying a ring nut 32, the stud being mounted in the spout 25 and the ring nut operating to clamp the plate in any verti- I an annular convex portion 34- bordered by annular flat portions 35 all as clearlyshown in Figure 45. Framed about the wheel W is an endless belt B formed of canvas or other suitable material and also trained about a pulley P mounted on a shaft 36 positioned within that end o'lithe table remote from the magazine M so that the periphery of the pulley is disposed above the surface of the table top. Suitab e openings are formed in the table top 16 to allow of the passage of the upper stretch of the belt B above the table top and forwardly in the direction of the arrow in Figure 1.

For the purpose of maintaining the corn liusks in proper position upon the belt B during the passage of the latter around the wheel W, gripping rollers R and endless belts B are provided and so arranged that the belts are maintained in contact with the flat portions 35 of the. wheel \V, itof. course being understood that the belt B and the corn husks are interposed between the wheel and the belts B, as clearly shown in Figure 4. The rollers are arranged in pairs, with the forward pair of rollers mounted on the confronting ends of shafts 37 journaled in bearings 38. The rear pair of rollers'are mounted in a similar manner on shaft-s 39, it being noted however that the shafts 39 are in a plane slightly above the shafts 37 so that the corresponding rollers occupy a similar position. This particular arrangement is for the purpose of maintaining the belts 13' in proper contact with the wheel TV so that the picking up and discharging of the corn husks is rendered automatic, while at the same time permitting of the discharge of the dough onto the husks during the period in which they are held firmly on the belt B.

To effect the discharge of the dough from the magazine M, a follower 39 is adapted to be superimposed upon the material as shown in Figure 3 and forced downwardly within the magazine by compressed air introduced into the magazine through a pipe 40 mounted in the cover 23 and connected to a flexible pipe 41 which latter in turn communicates with an air pump 42. A check valve 43 is arranged at the end of the pipe 41 and a relief valve 43 is mounted in the cover 93 which is manually adjustable to allow the escape of air from the magazine to maintain a predetermined air pressure within the magazine irrespective of the speed or dimensions of the pump.

The mechanism for actuating the pump 32 and the wheel lV may be of any suitable form. However, in the present instance I have shown a motor 44 mounted on the platform 17 and operatively connected to a shaft 45 through a pulley and belt connection. The shaft 45 in turn is operatively connected to the air pump 42 through a pulley and belt connection, and to a shaft 46 through a similar connection. The shaft 46 is journaled in hangers 47 arranged so that the shaft is disposed at rightsangles to the shaft 33. The shaft 46 is operatively connected to the shaft 33 by a worm 48 fixed to theshaft 46'and meshing with a gear 49 fixed to the shaft 33. The operation of the apparatus is as fol lows: The corn husksdesignated at H in Fig. 3 are adapted to be inserted between the forward portions of the .belts B and B, and with the wheel moving in the direction of the arrow it will be clear that the husks are fed forwardly and upwardly to a point beneath the discharge end ofthe spout 25. As each husk is inserted between the belts, the forward rollers R co-operate with the flat surfaces 35 of the wheel W in effectively gripping the end portions ofthe husks so that they are heldsubstantially taut over the convex portion 34 thus occupyingythe' position shown in Figure 4.. The husks are held in this position prior and subsequent to the passing of the spout and when reaching a. point below the spout the dough material is discharged upon the hush. Practically simultaneously with this discharge operation, the presscr plate 2i) operates to press the dough so as to cause it to adhere to the surface of the husks so that the only further operation necessary to complete the formation of the tamale is the folding of the husk to enclose the dough. The belt ll functions to feed the husks with their dough forwardly over the table T which operators remove and perform the folding operations in completing the tamales.

By virtue of the adjustment of the shutter 26 and the presser plate 29, it will be clear that the amount of material discharged upon each husk and the pressure with which it is packed can be varied in forming tamales of different sizes. It is to be understood that a wheel having a flat periphery can be substituted for the wheel lV when making tamales with a paper wrapping.

Although I have herein shown and de scribed onl one form of tamale making apparatus embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appendeijl claims.
