This invention relates to tobacco press and has for "its 'pri'mary obj ect' to provide, in a manner ashereinafterjset forth; a device "of such character which is thoroughly *eflicient @ziii operatiom and which is of-- exceedingly strong; simp-le a'nd inexpensiveconstruction; A further object of 'tl1'e invention'is to provid'e' 'at'oba'cc'o" press including 'a press board capable of movement in: opposite directions o longitudinally of a compression chamber to press' tobacco in 'eithenend of the chamber,

and' fu-rther includingautomatically operating means for retaining the press board in pressing engagement-with the tobaccopressed thereb'y aftenthe release of the power-for operatingrthe pi-ess board;

Ha ving end port ons thereof fixedly, secured totheposts -1 are'ta pair of 1 side members whichextendin plarallel spaced relation, and which preferably are formed of metal. At the endsof the :side' members Q-a-rea ail- 0f end members 3 which arepreferably formed of a metal and which are secured to the support 'ing posts 1; Theend members '3 coact with the side members? to provide a compression" chamber kwh'ich is'open at its top and bot- 85 tom; Secu'red to the outer faces of theside members 2 and extending longitudinally thereof are a pair of angle beams 5, the lower faces of which aresubstantially flush with the lower edges of the side members 2. $92.: eo

'cured t-o the outer faces of the side members 2 which extends a shaft 8. The shaft 8 projects from both sides of 'the pressfand isprovided atone end'with a detachablepower crank 92 The shaft 8 is journaled in a pair of bearings 10 which are dispose'dfbetween and fixedlythe press;' c The plates 11 are ofiappropriate w'idth to snugly between the side'plates 2 without bindin'gyandextend above and below the upper and lower edgesrespectivelyof the a plurality'of spacerelements which include relatively; short rigidtu'bes 12 haying bolts 13' 3 extending: therethrough and through the platesll; The tubes 12 maintain the plates 11in spaced-relation, While the bolts 13 main- "ta-in theinner faces of the plates 11 in contact- 1 ---with the end faces of the tubes '12.

Secured'to the upper and'lower-edges'of thelplates 11 are a pair ofrigid, endlessstrap's 14:, the side portions 15 of which are vertically disposed in slightly spaced relation to the

beams

5 and 6. Fixedlysecured to the inner faces of the vertically disposed portions 15" :on opposite sides of the press are ap'air of angular guides 16'Wl11Cll'iLIG located in spaced 2' relation to the bottoms of the Vertically dis posed portions 15, and end portions of which rest uponrthe upper faces of the beams'fi.

Fixedly secured to the innerfaces of the vr ticallydisposed portions 15 on oppositesides-1106" of the press are similar angular guides 17 which are located in spaced relation to the upper ends of the vertically disposed portions 15, and end portions of which bear against the lower faces of the beams 6.

Fixedly mounted on the shaft 8, on opposite sides of the press, and outwardly of the side members 2, are a pair of cog wheels 18, the teeth of which project upwardly through openings 19 in the beams 6 to provide for a movement of the press board longitudinall of the chamber 4 upon a rotation of the she. 8. Integrally connected with the straps 14, adjacent each side member 2, are a pair of pawls 20 which are adapted to extend at downward inclinations into engagement with the openings 19.

In the operation of the press, tobacco is suitably suspended to extend into the chamber 4 between the press board and one of the end members 3. The pawls 20, at the side of the press board adjacent the tobacco in the chamber are then swung upwardly about their pivots to a position such as indicated in dotted lines in Figure 3 and designated by the letter A. The shaft 8 is then rotated by means of the power crank 9 in a direction to move the press board towards the tobacco in the chamber by the engagement of the teeth of the cog wheels 18 with the openings 19 in the beams 6. As the press board moves longit'udinally of the chamber, the pawls 20 at the opposite side of the press board from the tobacco in the chamber successively engage in the openings 19. When the press board has moved a sufficient distance to firmly press the tobacco between the same and one of the end members 3, the power for rotating the shaft 8 may be released, and any return movement of the press board will be prevented by the following pawls 20 which engage the walls of the openings 19 which are adjacent thereto and maintain the press board in ressing engagement with the pressed to acco within the chamber.

It is thought that the many advanta es of a tobacco press in accordance with t is invention will be readily apparent, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the size, shape and arrangement of parts may be resorted to, so long as such changes fall within the scope of the invention as defined in the ap nded claims.

2. A press comprising, means to provide an elongated compression chamber adapted to receive in either end portion thereof a substance tobecom ressed, said chamber including a pair of si e members formed with longitudinally extending slots, a press board selectively movable in opposite directions longitudinally of the chamber to compress the substance therein, said press board including a pair of spaced plates, a plurality of spacer elements for-securing the plates of the pres board together in spaced relation, an endless rigid strap extending around the periphery 0 each plate of the press board and having side portions thereof disposed outwardly of said side members, a pair of beams secured to the outer face of each side member and projecting horizontally therefrom, a plural- 1ty of guide elements secured to said rigid straps for engagement with said beams, a shaft extending through the slots in the side members, said shaft being rotatably connected with the press board, means for rotating the shaft, coacting means on said shaft and one of the beams of each pair for moving the press board longitudinally of the chamber upon rotation of the shaft, and oppositely disposed pawls pivotally connected with said strap for engagement with the means on said last mentioned beams for maintaining the press board in pressing engagement with the compressed substance.

3. A press comprising, means to provide an elongated chamber adapted to receive therein a substance to be compressed, a press board movable longitudinally of the chamber to compress the substance therein, a rigid strap secured to the press board and having portions thereof extending along the outer faces of the side walls of the chamber transversely of such walls and in spaced relation thereto,

and guide members secured to said strap and-- disposed between the same and the side walls of the chamber. a

4. A press comprising, means to provide an elongated chamber adapted to receive therein a substance to be compressed, a press board movable longitudinally of the chamber to compress the substance therein, a rigid strap ecured to the press board and having portions thereof extending along the outer faces of the side walls of the chamber transversely of such walls and in spaced relation thereto, beams secured to the outer faces'of said side Walls and extending longitudinally of the chamber, and guide members secured to said strap and projecting inwardly into engagement with said beams. 5.
