LOUIS EVAREST BARBEAU, OF LONDON, ENGLAND.

DEVICE FOR TURNING BAGS.

SPECIFICATION forming part of Letters Patent No. 503,692, dated August 22, 1893.

Application filed October 19. 1892. Serial N0.449,321- (Ito model.)

To all whom it may concern:

Be it known that I, LOUIS EVAREST BAR- BEAU, a subject of the Queen of Great Britain, residing at London, England, have invented new and useful Improvements in Devices for Turning Bags, of which the following is a specification.

This invention relates to a device which is designed for use in bag factories for turning bags in the course of manufacture and also in flour mills, malt houses and other establishments where bags are required to be turned for cleaning them.

My invention has for its object to provide a simple and inexpensive contrivance whereby the bags or sacks can be turned more rapidly than by the use of the hands alone.

In the accompanying drawings consisting of two sheets :Figure 1 is a front elevation of my improved bag turning device. Fig. 2 is a rear view thereof, showing a sack in position thereon preparatory to being turned the sack being shown in section. Fig. 3 is a side elevation of the device with thebag shown in section. Fig. 4 is a top plan view thereof. Fig. 5 is an enlarged sectional elevation of the upper part of one of the standards, showing the anti-friction balls applied thereto and one of the caps which confine the balls removed. Fig. 6 is alongitudinal section in line w--w, Fig. 5, with both caps in place. Fig. 7 is a side elevation of a modified form of the device. Fig. 8 is a similar view of another modification. Fig. 9 is a sectional elevation of the upper part of one of the standards, Fig. 8, showing anti-friction rollers applied to the same and one of the caps which confine the rollers removed. Fig. 10 is a top plan view thereof with both caps in place.

Likeletters of reference refer to like parts in the several views.

In Figs. 1 to 6, inclusive, A represents abase plate secured to the floor or other support, or made sufficiently heavy to support the device without fastenings, and B B are upright bars or standards pivoted at their lower ends to upwardly projecting lugs or ears a formed on the base plate. These standards cross each other, and are adj ustably connected together, where they intersect, by a transverse clamping bolt 0 passing through slots d formed lengthwise in the standards and having a thumb nut 0. Upon loosening the thu mb nut, the clamping bolt may be raised or lowered in the slots of the standards so as to separate their upper ends to a greater or less extent.

eis a spiral spring connecting the standards between their lower ends and the clamping boltc and tending to spread the upper ends of the standards apart upon loosening the clamping bolt. The upper end of each standard is preferably provided with anti-friction balls or rollers. In the construction represented in Figs. 1 to 6, each staudardis provided with a row of anti-friction balls f which extend from the top of the standard to the outer side thereof. These balls are arranged in grooves formed in the adjacent sides of two cap pieces G secured to the upper end of the standard by a transverse bolt 9, as shown in Figs. 5 and 6. The ball grooves are so formed as to confine the balls therein'and at the same time allow them to revolve freely.

In the use of my improved device, the upper edge of the sack is first turned outwardly around the entire month of the sack to the depth of about two inches. This turned-over portion is then seized on opposite sides of the sack, placed upon the upper ends of the standards and then drawn downward over the same until the bottom of the sack rests upon the upper ends of the standards, whereby the sack is reversed or turned inside out. The halls f reduce the friction of the sack against the standards and facilitate the operation of turning. As the bag is drawn over these balls, those nearest the outer side of each standard will turn about a horizontal axis, substantially at right angles to the plane of the two standards, while those nearest the crown of each standard will turn about a horizontal axis substantially in the plane of both standards, as represented by the arrows in Fig. 5, which directions of rotation correspond with and are produced by the different directions in which the bag moves over each standard at different portions of its top.

By making the standards adjustable upon each other, as before described, they can be set at different distances apart to suit sacks of various sizes.

Instead of crossing the two standards of the sack-turner, they may be separated and conis drawn over them.

2 v scarce nected by an adjustable brace Hwhich is secured to these standards by transverse clamping bolts passing through longitudinal slots in the standards, as shown in Fig.7. In this modification the standards are inclined or' made to diverge upwar ly, S0 that upon adjusting the. brace H up or down,zthel-standf ards are contracted or spread apart.-

In the modification shown vin Fig.8, the standards are connected by an adj ustable brace, as in the construction shown in Fig. 7, but their lower ends are pivoted toindependent lugs instead of to a single lug, as in Fig.7.?

I In lieu of the balls f, anti-frictionrollersf'i may be employed, as shown in Figs. 8 and9.

In this case the axis of. the .outer roller of: each standardis arranged at. rightangles: to;

thevplane of the standards and theaxes ofthe inner rollers ina parallel plane therevvithpas.

shown, whereby substantially the same move-Q ment is produced in these rollers which takes" place in the anti-friction balls when thebag These balls .or roller-s are,- =however, not indispensable and may. be

omitted, ifdesired, and theupper ends-or heads of the standards. maybe rounded, seats to present asmooth bearing surface to the sack.

My improved, sack turner forms a very use,

ful accessoryto. bag ifactories,. flourmills-and other establishments in which a. large number of bags have to be turned, as it enables a much"greatennumberv to be turned in-a given time than byithe oldmethod-of usingonly the hands.
