DRYING-FRAME.

Specification of Letters Patent.

Application filed May 18, 1911. Serial No. 627,983.

Patented Sept. 8, 1914 To all whom it may concern Be it known that I, VVILLIAM B. Snnrnnn, a citizen of the United States, residing at Urbana, in the county of Champaign and State of Ohio, have invented certain new and useful Improvements in Drying-Frames, of which the following is a specification, reference being had therein to the accompanying drawing. Y

This invention relates to drying frames or stretchers for blankets, curtains or the like.

The object of the invention is to provide a drying frame which can be adjusted to stretch the blanket or other article to its full size and which will be of such a character and have the fastening devices so arranged as to stretch the blanket to its correct shape and size and to maintain the same inthat position while it is beingdried. It is also an object of the invention to provide such a device which will be of a construction suiliciently strong and rigid to enable it to handle at one time a number of blankets or other articles and which will be easy to operate; and, further, to provide means cooperating with the drying frame to facilitate the drying of the blankets or articles. 1

In the accompanying. drawings, Figure 1 is a top, plan view of a drying frame embodying my invention; Fig. 2 is a side elevation of the same; and Fig. 3 is a frac-,

tional detailview of the adjustable frame members and the connecting block therefor.

In these drawings I have illustrated one embodiment of my invention and have shown the same as comprising a frame which is preferably, but not necessarily, rectangular in shape and which has a part of its side members fixed against movement and has other of its side members adjustable relatively both one to the other and to the fixed side members. A fastening device adapted to engage the corner of the blanket or other article isarran ed at each corner of the rectangular frame and is so mounted as to be maintained at the corner of the frame and in the same relation to the blanket regardless of the adjustment of the movable members of the frame. In the present construction the drying frame is mounted upon a suitable base 1 which is preferably rectangubar.

lar in shape and hasmounted thereon four side members 2, 3, a and 5 constituting the drying frame. As here shown these side members are in the form of bars having. dove-tz'iiled grooves 6 in their upper surfaces. The bars 2 and 3- are rigidly secured to the base 1 and have no movement relatively either'to the base or to each other; The bars l and 5 aremovable relatively both one to the otherv and to the fixed bars 2 and 3. The bar 5 is arranged substantially parallel with the bar 3 and the bar 4 is arranged substantially parallel with the bar 2 and in a plane lower than the plane of the other members of the frame to enable it to extend beneath the bar 5., The bars and 5 are'connected one to the other at their pointof intersection, this connection being such as to permit them to haverelative movement. In the present instance the connection is formed by means of a block 7 adjustably. mounted on the bar a by means of a dove-tail projection 8 cxtending into the groove 6 of that This block has a lon itudinal extension 9 extending above the bar 5 and having a projection or tongue 10 extending transversely thereto and fitting into the clove-tail groove 6 of the bare. Preferably, a second block 11 is connected to or formed integral withthe extension 9 and has a projection entering the dove-tail groove 6 of the bar t on the outer side of the bar 5 This construction while not necessary to the operation of the device is sometimes desirable as it tends to elimina e any binding oftheparts and to facilitate the operation thereof. The barst blocks 12 and 13 havinglongitudinally eX- tending portions arranged above the respec five fixed bars and provided with transverse tongues or projections adapted to fit into the dove-tailed grooves of the fiXed'bars. These blocks are similar in construction to the block 7 shown in Fig. 3, but, insteadof being adjustably mounted on the bars a and 5, they are rigidly secured thereto and have movement relatively to thefiXed bars 3 and: 2 only. v 1' i Mounted on each of thecorner blocks 9, 12 and 13 is a fastening device adapted to engage the corner of the blanket :or other article and support the same in the proper relation to the corner of the frame. In the present instance these fastening devices are shown as spring clamps 14, but any suitable fastening device may be used. A similar fastening device is mounted on a block 15 mounted at the corner of the two fixed members of the frame. The fastening devices carried by the several corner blocks occupy fixed relations to the frame and to the blanket supported therein, and, when the blanket has been engaged by these fastening devices and the frame expanded to stretch the blanket, the latter will be retained at all times in a true rectangular position and will not be distorted or pulled out of shape. The outer ends of the bars 1 and 5 in addition to being connected one to the other are supported on suitable guides carried by the base 1. As here shown these guides consist of bars 16 and 17 rigidly secured to the base and extending at right angles to and beneath the bars 4t and 5, respcctively. The supporting bars 16 and 17 are provided with dovetailed grooves 18 to receive dove-tailed tongues or projections 19 secured to the lower surfaces of the bars 4 and o. in this manner the movable members of the frame are maintained in their proper relation to the fixed members of the f ame in all positions thereof and effectually prevented from turning or twisting under any strain which may be imposed thereon.

hiiounted upon each of the frame memhers is a series of fastening devices adapted to engage and support the edges of the blanket between the corners thereof. These fastening devices, indicated at 20, are similar to the fastening devices 1% carried by the corner blocks and are mounted upon blocks 21 having dove-tailed tongues or projections extending into the dove tailed grooves of the frame members. The bar 41 being arranged in alower plane than the other bars the blocks 21 mounted on that bar are of a greater thickness than are the blocks on the ether bars to support the fastening devices in substantially the same horizontal plane with the fastening devices carried by the blocks on the remaining bars. Any suitable mechanism may be employed for adjusting the movable frame members. 111 the present instance 1 accomplish this by means of a series of cables, preferably of steel, which are indicated at 22, and which are secured at their outer ends to the outer sides of the respective movable frame members, thence extend outward about guides 23 mounted near the outer ends of the fixed frame members and the supporting bars 16 and 17, thence inward and about other guides 2 1 to a drum 25 having one end of its shaft squared, as shown at 26, to receive a crank for rotating the same. A

pawl and ratchet, indicated at 27, holds the drum against rotation in a rearward direction. It will be apparent, therefore, that when the drum is actuated and the cable wound upon the same the movable frame members 4t and 5 will be carried outward and that the corner blocks 12 and 13 will move outward along the line of the fixed frame members while the corner block 7 will move outward in a line diagonal to the frame. The movable bars may be returned to their contracted or normal positions in any desired manner, but, in the present instance, 1 accomplish this by means of springs 28 each of which is connected at one end to one of the movable frame members and at the other end to one of the fixed frame members, the arrangement being such that the springs tend at all times to move the movable bars 4: and 5 toward the respective fixed bars 2 and 3.

When desirable a suitable agitator may be provided to impart movement to the blankets supported by the drying frame and facilitate the drying thereof. In the present instance 1 have shown such an agitator in the form of a board or strip 29 having at its opposite ends trunnions 30 journaled in the end members of the base 1 and provided at one end with a driving pulley 31 or other suitable means for revolving the same. The arrangement of this agitator is such that as it revolves the edges thereof will come in contact with the blanket in the frame and lift the same, and, after the edge of the agitator has passed, the blanket will drop. in this manner a constant rising and falling movement is imparted to the blanket which materially facilitates the drying thereof. I

'lhe operation of the device willbe read ily understood from the foregoing description of the several parts thereof and it will be apparent that when a blanket is mounted within the frame and secured thereto by the several fastening devices, the expansion of the frame will not only extend the blanket to its correct size and shape, but will maintain the same in this position during the drying process, this being due to a large extent to the manner in which the corner fastening devices are arranged and this arrangement being such as to maintain them at all times in the same relation to the drying frame and to the blanket supported therein. it will further be apparent that the device is of asimple construction and easy to operate.

(While 1 have shown and described one form of the invention it will be understood that this form is chosen for the purpose of illustration only and that 1 do not wish to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
