REVERSING MACHINE.

Specification of Letters Patent.

Patented June 27, 1922.

Application led December 14, 1920. Serial No. 430,793.

To all 'whomz't may concern.'

Be it known that I, MAHLON A. SiDwnLL, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Reversing Machine, of which the 'following` is a specification.

My invention has special reference to mechanism more especially designed for use as a means for holding sacks or bags whereb y they may be readily reversed; that is, turned inside out for cleaning purposes, removing any remnant of the stuiiing or other contents that may have been contained therein and which tends to adhere to the inner side of the bags, sacks or other similar article,

My invention is more particularly adapted for the purpose of turning 'toy animals, dolls, pin cushions and other like articles which have to be turned right side out after being stitched upon a sewing machine.

Primarily, my invention seeks to provide a means of the character stated adapted for conveniently and expeditiously facilitating the turning of the toy body or other like fabric body arranged for being stuffed with saw dust or other like filling and which is of an inexpensive, simple and compact arrangement, onto which the object to be turned may be easily adjusted and clamped and in such manner that the operation of turningor reversing` the bag or other hollow object can be instantly accomplished by the operator and the said object, when turned, quickly removed or disconnected from the holding means,

`With other minor objects in view that will hereinafter be apparent, my invention consists of a-reversing means that embodies the peculiar features of construction and novel combination of parts, fully stated in the fol` lowing detailed description, speciiically mentioned in the claim and illustrated in the accompanying drawings, in which:

'Figure l is a perspective view of my improved construction of reversing machine, the movable article clamping devices being shown at their elevated or clamped position.

Figure 2 is a side elevation of the movable clamping member and its actuating means, the same being shown at the lower or clamping position.

Figure 8 is a detail vertical section of the members.

:fixed an upright stationary clamping member. The table is also provided with vertical bearingsto sustain a verticallymovable frame that is mounted in such bearings. This frame carries a clamping member which is adapted to be brought down and engage the stationary clamping Vmember so as to grip ythe bottom of the article to be turned between the opposing parts of the clamping The parts are so arranged and designed that the operator can conveniently place the article to be turnedover the lower end of the upper or movable clamping member and, by foot pressure, bring the movable clamping member down to grip the article between it and the'stationary clamping member, the operator meanwhile grasping the outer or open end of the article which, when the clamping members are together, he turns down over the stationary clamping members and thereby reverses the object the sack, pin cushion, toy shaped body, etc.- withoutthe use of special tools or without the necessity of making hand adjustments of any of the parts of the mechanism.

Referring to the details of construction, l designates the hollowv tube, which is hereinafter termed the upper movable clamping member, and this tube has a coupling head 7 which screws onto a slightly larger tube 13, the diameter of the said tube 1 varying according to the work to be done but always with a corresponding change in the diameter of the opposing rod 2, with which it cooperates. i

The rod 2 has an enlarged base provided with a threaded shank 8 for fitting a screw socket in the tablef18, and the said rod 2, in practice, may be of various lengths corresponding with the distance that the tube 13 extends from the tube 14, presently again referred to.

4 indicates a standard which is boltedto the table top and it includes a bearing 3 in which is slidably secured the tube 14 before referred to, and which constitutes a standard in which the end 13 ot the U-shaped member is adjustably mounted.

The lower end ot' the standard tube 14 passes through a guide 12 in the table 18 and is joined, by a coupling 9, with a bent tube 15, that includes a pendent portion 15a which slidably engages the bearing bolted onto the inner iace or a cross member 21 of the table trame, which includes opposite standards 16--16 and 2.3-23, braces 17-17 and a bottom cross bearing 22.

The lower end ot the part of the bent member 15, terminates in a foot pedal 11 for conveniently pulling down the movable or upper clamping member, it desired.

24 designates a stout coil spring that tits around the upper end of the standard 14, which has one end resting on the bearing 3 and the other end engaging a collar 5 adjustably mounted on the said standard, as is clearly shown in Figure 3.

Arranging the parts that constitute my reversing-machine, as shown and described, the operation thereof will be readily apparent to those familiar with the handling ot bag turning mechanism, in which devices are provided for holding` the bag or other fabric object to be turned.

In my construction, the object to be turned is slipped up over the hollow tube which is positioned as indicated in full lines on Figure 1. rEhe toot ot' the operator is then placed on the pedal-11 which, when pressed down, through the connections 15, 14 and 13. depresses the movable parts to the p0- sition shown in Figure 2, with the lower end otlthe tubular member 1 abutting' the bot tom ot the object and clamping such object bottomdown onto the bulbular end ot the Vstationary member 2, thereby holding the object firmly between the said bulbular end 2() and the end 19 ot the member 1.

The operator then grasps the open edges around the mouth of the object, pulls the said mouth down over the rod 2 and thereby reverses the said object, by turning it inside out.

Foot pressure is then removed from the pedal 11, which allows the upper or movable part of the machine to automatically, under action of the spring 24, return to the uppermost or normal position. The turned object is then removed from the member 2 and the process ot reversing is repeated on another like object.

lith my construction of reversing means, the operation of gripping the object to be turned and turning it inside out can be quickly, conveniently and satisfactorily accomplished without the need of adjusting or specially setting any of the clamping or object holding parts, after the object has been turned, as stated,since all that is necessary is to release the toot pressure, which allows for the separation of the opposing clamping` elements 1 and 2 and thereby pro vides sulticient space between the said elements for withdrawing the turned object t rom between them.

Vvlhile the special arrangement of the parte as shown and hereinbetore described presents a practical development of my invention, it will be understood that I do not limit myself to the precise arrangement -of the parts shown, since the said parts may be readily modified and varied to -suit the particular work desired to be done, without departing frein the broad features of my invention as comes within the scope of the appended claim.

lhat I claim is:

In a reversing machine for the purposes descril'ied. the combination with a supporting trame, including leg members and a table top mounted thereon, and a standard secured to and extended vertically trom one end of the tabletop and including a vertically apertured bearing; a clamping post lixedly connected to and projected vertically above the. table, a plunger'trame which includes a vertical member slidably engaging the apertured bearing ot'the standard and movable through the table, an extension secured to the lower end of the said vertical member, the said extension including a -foot lever eipiipped pendent member, a guide on the table supports in which the foot lever equipped pendent extension is slidably mounted, a spring device engaging the vertically slidable member and the apertured bearing in which the said bearing is mounted, whereby to normally force the said vertical member upwardly, when pressure on the toot lever is released, and an inverted U-shaped trame adjustably attached to the said vertically shittable member and a clamp member attached to the inverted U-shaped trame and supportedtor being brought down into contact with the stationary clamping member, when pressure'is appliedto the toot lever, whereby to clamp the article to be held between it and the said opposing lixedly held clamp.
