WILBER HUNTER SCOTT, OF OTTAWA, CANADA.

TEA-PACKING MACHINE.

Specification of Letters Patent.

Patented June 5, 1906.

Application filed May 5, 1905. Serial No. 259,041.

To all whom it may concern: 7

Be it known that I, WILBER HUNTER SCOTT, grocer, of the city of Ottawa, in the county of Carleton, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Tea-Packing Machines, of which the following is a specification.

My invention relates to improvements in tea-packing machines; and the object of the invention is, first, to provide a plunger for a tea-packing machine capable of being moved out of vertical alinement with the diebox of the machine and Which is capable of being adjusted so as to adapt the pressure thereof to different grades of tea, and, secondly, to provide a detachable die-box for the machine which will be constructed so as to retain a sure grip on the package of tea while it is being pressed and also to allow of the said package being readily removed therefrom and it consists, essentially, first, of a supporting-standard having an L-shaped foot-lever pivotally secured to the lower portion of the standard, supporting-bars pivotally connected intermediate of the length of the said lever provided at its u per end with an L-shaped bearing-arm,a p unger-rod designed to extend through the end of the said arm and to be adjustably held therein, and a plunger-head secured to the lower extremity thereof, a spring connecting the outer end of the lever to a suitable portion of the standard, and, secondly, of a die box the sides and back of which are formed in one piece, suitable hooks forming part of the back thereof designed to hook over corresponding projections forming part of the main standard of the machine, the front and bottom of the box being formed in one piece and being pivotally connected between the lower front angles of the sides by asuitable bolt and the top having a suitable hinge connection to the top edge of the front of the box, the various parts of the device being constructed and arranged in detail as hereinafter more particularly described.

Figure 1 represents a perspective view of my machine, a portion of which is broken away to exhibit more clearly the construction thereof. Fig. 2 is a vertical longitudinal section through my machine, showing the plunger before it is depressed when thrown out of operation. Fig. 3 is a similar view to that shown in Fig. 2 with the plunger and foot-lever depressed so as to compress the tea in the package. Fig. 4 is an enlarged perspective detail of the die-box, the front thereof being thrown down in the position it would assume when the form is inserted or when the package of tea is ready for removal. Fig. 5 is an enlarged detail of a form on which the lead coverin of the package is wrapped before it is place in the die-box.

In the drawings like letters of reference in dicate corresponding parts in each figure.

A is the main standard, provided at its lower end with suitable legs a a The upper end of the standard is provided with an L- shaped baokwardly-extendin portion a provided with pins a a, exten ing outwardly to each side thereof. a is a lug forming part of the leg at.

B is a foot-lever pivotally connected tothe lug a by the pin b and provided intermediate of its len th with a vertical slot 1) It will be noticed filat the lower end of the standard A extends downwardly through this slot, thereby forming a guide for the foot-lever B.

O C are bars pivotally connected at their lower end to the foot-lever B by a pin 0. Between the bars 0 O at their upper end is secured an L-shaped arm D, provided with a tubular bearing d, attached to or forming part of the outer end thereof.

(1 is a plunger-rod extending through the tubular bearing 01 and adjustably secured therein by a set-screw d d is a suitable plunger-head secured to the end of the plunger-rod by a set-screw d.

d is a spiral tension-spring connecting the foot-lever with a suitable portion of the standard A.

' E is the die-box, formed of the back portion 6 and the side portions 6.

e designates hooks attached to or formin part of the die-box and designed to exten over lugs e forming part of the main standard A. It will be seen that these lugs e and hooks e are wedge-shaped, so that the weight of the die-box and the pressure upon the same always tend to draw and hold the diebox tight against the standard.

e designates lugs forming part of the diebox and extending to each side of the standard A.

e designates lugs extending outwardly from the lower front angle of each side of the box. It will be seen that the front, top, and bottom of the box are open.

F is the front of the box, and F is the bottom, which are formed inone piece and pro ICC responding hinge-lugs f, connected to the" hinge-lugs by the p1Ilf f G designates handles extending out of each side of the lid of the die-box f part of the front of the die-box and having an L-shaped lower end f designed to come in contact with the lower edge of the die-box, so as to hold the front thereof in a suitable open position. I

G is the form u on which the lead covering of the package 0 tea is wrapped before it is placed in the machine.-

Having described the principal parts of my invention, I will briefly describe the operation of the same.

The lead covering of the package is first Wrapped upon the tin form G in the usual manner, the bottom of the wrapping being folded under, so as to form the bottom of the package. The form is then placed upon the front of the die-box F and the die-box is then closed. The operator then brings the plunger by hand vertically over the center of the die-box, and then he depresses the foot-lever B, so as to carry the plunger down into the form G, as shown in Fig. 3, so as to depress the tea within the form. The foot-lever is then relieved, and the plunger flies up into its upper position by means of the spring d and it is thenthrust back by hand against the pin a thus carrying it out of vertical alinement with the form G. This enables the form G to be readily removed from the die-box, leaving the lead package of tea therein. The top of the package is then folded over in the usual manner, and the lid f of the die-box is swung over on to of the package, so as to complete the pac age and give it an even surface. The front of the diebox is then thrown open and the packa ge removed, and the operation can be repeated.

I may state that in old machines of this class where a stationary plunger is used that the form when it is lifted out from the diebox has to be carried up over the end of the plunger and held thereon till the package is complete, when it is removed.

It will be seen that in my machine by swinging the plunger from over the diebox the form can readily be removed from the machine in one operation, and thereby save handlingit twice. It will also be seen that in making my plunger adjustable within the bearing D it may be adapted to different grades of tea Where difference of pressure is required, thereby preventin the breaking or crushing of the leaf. It wi 1 also be seen that in my form of die-box, the bottom and front being formed in one piece and pivotally connected between the sides of the box, the greater the pressure that is brought to bearupon the tea the greater the grip on the package becomes between the front and the back of the die-box.

' It will be seen from this description that my machine is very simple in construction and that a package of tea may be formed with a minimum amount of labor and that f is a downwardly-extending lug forming the package when formed will have an even neat appearance.

What I claim 2 s my invention is 1. In a tea-p;cking machine the combination with the main standard, of a suitable die-box secured thereto, a depressible plunger supported vertically above Slld die-box adapted to be swung out of vertical alinement with the said die-box as and for the purpose specified. v 2. In a tea-packing machine the combination with the main standard, of a suitable die-box secured thereto, a vertically-adjustable plunger supported above said die-box adapted to be swung out of vertical alinement with the said die-box as and for the purpose specified.
