Patented May 13, 1941 CIGARETTE MAKING DEVICE Clarence E. Karst, Cincinnati, Ohio, assignor to The Brunhoff Manufacturing Company, Cincinnati, Ohio, a corporation of Ohio Application June 6, 1939, Serial No. 277,669

2 Claims.

This invention relates to improvements in cigarette rolling or making machines of a hand operated pocket carrying size and type for domestic use.

An object of the invention is to provide a dople construction with a minimum number of parts readily and easily assembled for low cost production.

Another object of the invention is to form the major parts of the device from sheet metal,

shaped for mechanical functioning and to reinforce or give sturdiness to the structure, permitting the same to be compactly made from comparatively light gauge stock to minimize its weight desirable for a pocket carrying article.

Other objects and further advantages will be more fully apparent from a description of the accompanying drawing, in which:

Figure 1 is a top plan view of the improved cigarette rolling machine in a position for load ing, with the apron operating slide in its rearmost position upon the supporting frame.

Figure 2 is a side elevation thereof.

Figure 3 is a section on line 33, Figure 1.

Figure 4 is a central vertical section of the rear end of the machine with the slide advanced to a position where the apron encircles the cigarette supply of tobacco for pressing it into cylindrical form.

Figure 5 is a section showing a further advance of the slide with the wrapper applied about the cylindrical stem of tobacco.

Figure 6 is a section with the slide close to the end of its forward stroke about to release the finished cigarette.

Figure '7 is a section on line ll, Figure 2.

Figure 8 is a section on line 8--8, Figure 2.

Referring to the drawing, l indicates a body or frame formed from a single metal sheet, bent into rectangular channel form, providing an open top. Each side wall 2, 2, of the frame at its upper end has a lateral outwardly extended flange 3 longitudinally of the length of the wall. The flanges 3 provide parallel guides or rails for slidably mounting a slide or carriage 4 extending across the open top of the frame. The cross web or base of the channel, which normally integrally joins with the side walls for the forward portion thereof, is longitudinally slitted at the base of each wall to separate the same from the walls, and pressed upwardly within the channel to provide a table or platform 5 within the confines of the frame, and preferably slightly inclined upwardly toward its forward end.

mestic cigarette rolling or making device of sim- The platform at its rear end is elevated or offset from the base or web portion 6 with which it integrally joins. The rear portion of the platform inclines downwardly, and terminates with a perpendicular or curved riser portion, which at its lower end joins with the base or web 6.

The stepped formation permits a portion of an apron l to be depressed below the rear of the platform, over which the apron spreads to fold a portion-of the apron immediately in rear of the platform into a loop to provide a pocket for the reception of a quantity of tobacco required for the makings of a cigarette.

The sheet metal blank for the frame, at the forward end of the platform portion, is ext-ended beyond the forward edges of the side walls. This extended portion is bent reversely into an angle flange or bead 8, depending from the lower side of the forward end of the platform. The opposite ends of the bead, each have a tab 9 integral therewith, which is crimped to overlap upon the outer side and over the forward edge of an adjoining side wall. This reinforces the forward end of the frame, and confines the side walls against outward yield or spread.

The slide 4 is also formed of sheet metal, and pressed into channel form, and is applied upon the frame in an inverted position thereto to extend above and bridge across the upper over side of the frame with its side walls in registry with the side walls of the frame. The longitudinal extremities of the side walls of the slide are bent outwardly and into a reverse bend flange, each for slidingly intermeshing with a rail flange 3 of the frame confining the parts relatively against lateral displacement from one another while guidingly and slidingly joining the parts. The

slide is shifted or reciprocated back and forth upon and over the frame in the operation of making a cigarette, and carries and houses a roller Ill having its opposite ends journalled in the side walls of the slide, and the periphery of the roller located slightly above the platform to avoid contact therewith.

The apron I is engaged over the roller and preferably constitutes a strip of fabric having one side or surface rubberized, which is disposed uppermost in the device. One end of the apron, as a rear end thereof, is fixed within the frame by means of a rod H which traverses the side walls of the frame and extends through a hem formed on the end of the apron. The rod l I has one of its ends bent at an angle to provide a head l2 which has its extremity formed with the return bend l3 to provide a crotch for engagement,

about a tang I4 produced by an angle slot l5 punched through a side wall of the frame.

The rod in attaching and assembling the aprons within the frame is engaged through apertures in the side walls of the frame, and through the hemmed end of the apron with the head of the rod in a position perpendicular to the base of the frame. This permits a portion of the head to be engaged through the wall and position the crotch for engagement about the tang in swinging the head from its perpendicular position to one side thereof, passing into the curved or angle portion of the slot for latching or interlocking with the tang, thereby securing the rod against longitudinal displacement.

The parts are fitted to frictionally bind together, requiring the head to .be forcibly shifted for release. The construction provides a,v very simple and efficient method for assembly of the parts, easily manipulated so that a user can readily replace or renew the apron.

The opposite or forward end of the apron is fixed within the forward end of the frame or casing l in substantially the same manner as hereto-fore described for the rear end. The apron extends over the beaded edge of the platform to be secured beneath the platform by a rod l I, the rod having its head end anchored to the wall as previously described.

To make a cigarette, the slide is shifted or positioned to the rear end of the frame to permit a portion of the apron, the apron possessing sufficient slackness, to be depressed into a loop or recess betweenpthe rear end of the platform and roller in the slide. This forms a pocket for the reception of a desired quantity of tobacco for the cigarette. The side walls of the frame serve as enclosures for the pocket as the apron is approximately the width of the spacing between the walls of the frame.

A sheet of wrapper paper is placed upon the apron over the rear end of the platform with its forward margin moistened or rendered with an adhesive stripe for sealing the wrapper upon.

itself when wound about and enclosing the tobacco. Upon moving the slide forward, the loop formed for holding the tobacco is closed, enveloping the tobacco, and as the travel of the slide is continued, the tobacco is rolled, giving it a truly cylindrical contour and advanced over the wrapper sheet which is wound about the tobacco to enclose the same, and the end margin when reached is slid to a convolution of the sheet. When the slide has reached the end of its forward stroke, the apron fold which encircles the cigarette is opened, discharging the finished product.

I am fully aware that the method and principle employed for domestically making a cigarette is old in the art, and is utilized in the present structural development of the device, as it provides for simplicity, ease of operation,

and adaptability for conveniently producing a cigarette equally comparable to a commercially a u tv Having described my invention, I claim: 1. A sheet metal casing providing opposing side walls and a rod, the rod being supported inthe side walls and engaged through an aperture in each of the walls, one end of the rod being bent to provide a head of 'a form to interlock with an adjoining side wall, and the wall being slotted to receive a section of the head therethrough for bringing the head into straddling connection with the wall.

2. A rod providing a support between a pair of sheet metal walls and traversing an aperture in each of the walls, one end of the rod being bent at right angles to form a head having a hoolc extremity, and one of the walls having a slot radially of the rod traversing aperture to receive a portion of the hook end of the head, the slot terminating in an arcuate extension for swinging the hook end of the head into a wall straddling position out of registry with the radial portion of this slot and into interlocking engagement with theside wall.
