VENTILATING ATTACHMENT FOR PRESSING MACHINES v Filed Aug. 9, 1935 Allllllllll- Patented Jan. 28, 1936 UNITED STATES PATENT OFFICE'.

A vEN'rmATING A'rrficmmm Foa i PaEssmG MACHINES l 13 Claims.

Heretofore in pressing machines for garment and laundry purposes, which have press elements between which the articles are pressed, the heating medium supplied to one of the elements causes the temperature in .proximity to the machine, and at the places necessary to be occupied by the operator, to be very high, thereby rendering working conditions very disagreeable and uncomfortable.

It is one of the objects of the present invention to overcome these diiliculties, objections, and inconveniences and to provide an improved attachment for apressng machine of this character, which will remove the heat from the place which the operator occupies and thereby 'provide more comfortable working conditions.

The invention consists further in the provision oi a hood for the movable press member, which latter is usuallythe heated member, and which hood is secured to and is movable therewith, the hood being so constructed and arranged as to provide an inlet opening or slot encompassing the edge of the movable press member, and being provided with a. discharge outlet, means being associated and carried with the hood for inducing a circulation of the air through the hood and around the pressing members, to be discharged vfroml the hood and directed away from the operator.

A further object is to provide an improved at- I tachment of this character which forms a part of the movable press member, so that the pressing machine may be readily shifted and moved into another position to permit re-arrangement vof the machine, without interfering with the hood or its associated intact.

'To the attainment/of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the featureaof novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention, and in which Figure 1 is a side elevation of a portion of a pressing machine of this character,` having r'a' Ventilating attachment connected therewith, constructed in accordance with the principles of this invention.

I Figure 2 is a top plan view of the parts shown in Figure 3.

Figure 3 is a sectional view taken on line 3 3, Figure 2.

Referring more particularly to the drawing,

parts, lall of which remain the invention is shown in connection with a pressing machine which is diagrammatically i1- lustrated, the numeral I designating generally the machine frame having a stationary member II supported thereby and a movable pressing 5 member or buck I2 carried by anvarm I3 piv otally supported at I4 to an 4arm or bracket I5 extending from the machine frame. The arm I3 has' an operating handle IB and a counterwelght Il connected thereto and with a counterbalancing spring I8.

All of these parts are of the ordinary and well known construction and as before indicated, are merely illustrated diagrammatically to show one form of pressing machine with which this invention can be used.

The invention consists essentially of a hood I9 constructed of any desired or suitable material, preferably of sheet material shaped into the proper form to provide an open side and a 20 reduced portion 2| to form a fan chamber 22 which connects with the inside of the hood, and

v the fan chamber is provided with a discharge outlet 23.

This hood may be of any desired coniiguration, but is constructed to be somewhat larger than the movable head or pressing member I2 and is secured in position and supported for movement with the movable head in any desired or suitable manner, such as by means of brackets 24, so that when the movable member I2 is raised and lowered, the hood I5 will be raised and lowered therewith.

The movable member I2 is supplied with a heating medium in the usual manner, such as by means of pipes 25 and the hood I9 is of such a size to provide an open slot 26 around the edge of the movable head or member I2 and the skirt of the hood may, ii.' desired, be of a length that it will extend below the upper surface of the stationary 40 member II of the pressing machine.

Within the fan chamber 22 is located a fan 21 which preferably is mounted to rotate about an' upright axis 28, the latter being the shaft of a motor 29 which is also arranged within the fan 45 casing or housing 22. This fan and motor preierably constitute a unit and are supported in position in any desired or suitable manner, such as by means of supports or brackets 30 carried by the hood.

The fan 21 is preferably arranged adjacent the outlet opening 23 and a screen or reticulated member 3| covers the opening 23 so as to protect the fan.

With this structure it will be manifest that the 55 hood becomes an integral part of the press and particularly of the movable pressing member or headv I2.

The motor is operated in any desired or suitable manner, that is current is supplied thereto by means of the conductors 32 leading from a suitable source of supply of current.

' Obviously, the fan chamber 22 may be of any desiredconguration and the fan may be propelled by any suitable means, but preferably by means of an electric current and the motor is preferably electric.

In operation and when the parts are in the position shown in Figure 3, the fan 21 rotates in such a direction as to cause a draft of air to enter the slot 26 between the movable head and the lower edge of the hood, preferably encompassing the movable head and a portion of the stationary head when the movable head and hood are lowered, and will be'expelled-through the discharge opening 23 in the top of thev hood or in'` the fan chamber 22, thus drawing the heat away fromthe person operating the press and forcing it out through the top of the hood, where it may rise to the ceiling and may be removed or withdrawn by suitable exhaust fans or any other suitable means.

With this construction it will be manifest that the hood will not be in the way of the operator and will be moved upwardly and downwardly or toward 'and away from the stationary pressing member I I with the movable head. At the same time the fan will be constantly operating and will draw the heated air into the hood and discharge the same through the outlet opening 23 away from the operator, thereby providing more comfortable working conditions for the' operator.

The fan being continuously operated, will also continue to draw away the heated air from the operator even when the movable member and hood are raised.

y(With this construction it will also be manifest that the motor, i'anA and hood become an integral part of the machine, the only outside connections being the conduits for conducting the current to the motor, if an electric motor is employed, or the conduits for supplying the necessary power when an hydraulic or other iiuid actuated motor is used, and with this construction it will be manifest that the machine can be readily shifted inl its position upon the door so as to permit rearrangement of machines when desired, without the necessity of having to dismantle any couplings or outside connections.

While the preferred form of the invention has f been herein shown and described. it is to be understood that various changes may be made in the details of construction and in the combination and arrangement. of the several parts, within the scope of the claims, without departing from the spirit of this invention.
