(o1. 22a-_75) This invention relates to stretchers for socks and stockings, to be used in preserving the size and shape of a sock or stocking while it is drying after having been washed. An object of the invention is to provide a sock or stocking stretcher arranged to operate in a novel and extremely simple manner. The in parts being broken away and one of the clamps being shown in the raised position; Fig. 9 is a detailed sectional View of the same taken on the line 9_9 of Fig. 7; Fig. 10 is a detailed sectional view of a modiñed form of the clamp mechanism; Fig. 11 is a horizontal sectional view of the vention contemplates the use of a form compris same taken on the line II-II of Fig. 10; and ing telescoping parts one of which is shaped to Fig. 12 is a detailed sectional view of another iit into the foot of thel stock to be stretched and 10 modification of the clamp mechanism. the other of which is shaped to ñt into the leg As an example of one form in which the in of the sock, together with means for clamping the vention may be embodied, I have shown in the leg of the sock to the leg part of the form and drawing a sock stretcher embodying a two a screwjack device for extending the leg portion part, telescoping form having the general out of the form so as to apply tension to the sock. 15 line of the sock to be stretched and including A further object of the invention is to provide, a foot member I2 and a leg member I3. The in a sock stretcher having the characteristics set form members I2 and I3 may be constructed out forth in the preceding paragraph, an extremely of any suitable material of adequate thickness simple and quickly operable clamping device for and strength, such as cast metal or molded clamping the leg of the sock to the leg of the 20 plastic. I prefer to use molded plastic because of form. the more pleasing appearance that it gives the Another object of the invention is to provide ñnished article. a sock stretcher which may be easily put into The foot member I2 has cutout apertures I4 the sock and does not have any projecting parts therein which facilitates the circulation of air to that would catch in the material of the sock. 25 the foot portion of the sock being stretched and Prior devices have been subject to the objection thereby hasten the drying process.

The Wall of the sleeve member I_6 is tapered gradually Fig. 4 is an end View of the stretcher; to a thin end edge 2I at the inner extremity Fig. 5 _is an edge elevation of the stretcher; thereof. ~ Fig. 6 is a transverse sectional view of the foot 55 Where theshank member I5 joins the foot portion of the stretcher taken on the line B-B member I2, the latter is provided with a laterally of Fig. 1. ` ` thickenedankle region 22 having at its upper extremity a shoulder 22’ that extends entirely around the foot member I2 and is substantially Fig. 8 is a sectional view of the same detail, 60 iiush with the edge 2I of the sleeve I6 so as to Fig. 7 is a. detailed sectional view of the clamp mechanism taken on the lines 'I---'I of Fig. 3; ' 2,413,305 3 spread the sock and guide it over the edge 2I as the sock is being slipped on to the form. The shoulder 22' may also serve as a stop to limit the retractingmovement of the leg member I2 by engagement of the edge 2I thereagainst. The foot member I2 and leg member I3 are urged apart by a screwjack comprising a screw shaft 23 threaded through a threaded bushing which is pressed into a counterbore 25’in"the' outer extremity of the hole 20. The vscrevv shaftv 23 extends into the hole 20. At its outer end, the screw shaft 23 has an annular flange 26 and a pair of bearing surfaces 21, 28 disposed at either 4 ends of the trunnions 39 are flattened as at 48. When the clamps are in their closed positions, the cylindrical surfaces of the trunnions 39 are in engagement with the flats 41 of the screw 46, and the clamps are held snugly in the channels 4I by the tension of the springs 43, tending to uncoil these springs. With the ñats 48 of a clamp yoke 38 engaged against the flats 41 of the screw 46, the yoke will be held vin the outstanding position of the upper yoke shown in Fig. 4. This position is also indicated in Fig. 8, in broken lines. The flats are heldin engagement with each other by the pull of the coil springs 43 toward the screws side of the fla-nge. The flange 26 and bearing 46. This is a lateral pull which is developed as surfaces 21, 28 are rotatably mounted in a split the-result of flexing of those portions 490i springs bushing 29 which is mounted in an opening 30 43 which extend from the coil portions 50 offthe in the end wall 3I of the leg member I3. The springs to the screw 46. split bushing members 29 have ñange members 32 A modified form of the clamp tensioning means which abut the outer end surface of the end wall 3| and, at their opposite ends, have reduced 20 is shown in Fig. 10. In this modiñcation, the trunnions 39a. are journalled in the bottom wall externally threaded neck portions 34 onto which of the socket 42a as indicated in Fig. l1, and the is threaded a locknut 35. intermediate portions of the trunnions 39a are At this point it may be noted that in assem ñattened to provide cams 5I that extend radially bling the screw shaft 23 in the leg member I3 from the axes of the trunnions 39a as shown of the form, the split bushing members 29 are in Fig. 10, and engage the inner face of a split placed in embracing relation to the bearing sur ring spring 52. When the cams 49 are in their faces 21, 28 and the flange 26, and the assembly positions shown in Fig. 10, they will be main of bushing members and shaft is then passed tained therein by the embracing pressure of the into the opening 30, which confines the bushing sections 29 against spreading. The assembly is 30 spring 52, and the clamp yokes will thereby be yieldingly pressed against the channels 4 I. When then secured in place by tightening the nut 35 the clamp yokes are moved to the position indi on the threaded members 34 within the sleeve cated in broken lines at 53, the pressure against I5. The shank member I5, with the threaded the cams 5I will be on center and the clamp yokes bushing 24 installed> therein, may then be ap will be thereby held in these positions with light plied to the end of the shaft 23, and the shaft 35 restraining force. 23 is then rotated to draw the threaded bush In Fig. 12 I have shown a further modification ing 24 thereover and to draw the shank member of the clamp tensioning mechanism. In this I5 into the sleeve I6. modification, the trunnions 39h are dat as shown Rotation of the screw shaft 23 is effected by and are each fulcrumed at one edge in an end means oi a handle 33 to which is attached the 40 region 54 of the socket 42D which is in this case shank end 36 of the shaft 23. This attachment oval shaped. The opposite edges of the trunnions may be accomplished by molding the handle 33 39h are yieldingly engaged by an elliptical spring onto the shank end 36. 55 which is compressed as the jaws are swung Carried by the sleeve member I6 are a pair from their open positions (shown in Fig. 12) to 45 of clamps each comprising a yoke 31 formed of their closed positions, and Vice versa. During wire and having side arms 38 provided, at their such movements the trunnions 39h will passdead ends, with inwardly extending trunnions 39 and center with reference to the pressure of the spring connected by a central region comprising a jaw 55 against them, and consequently they will be 40.. When the yoke is in a clamping position, the. jaw 4U cooperates with a channel 4I in a 50 yieldingly held either in the open or the closed positions as the case may be. Spring 55 is in respective side of the sleeve member I6. The the form of an open ellipse, and the central sidearms 38 are ñattened and knurled to facili or web portion thereof is adjacent the ends of tate'their being grasped between the fingers, for the trunnions 39h when the jaws are in their manipulating the clamps. The trunnions 39 of the respective clamping yokes 38 are received in 55 closed positions. The pressure against the trun nions in these positions is thus greater than the sockets 42 in the end wall 3I of the leg member pressure against the trunnions when the jaws are I3. The trunnions 39 of one yoke are arranged in the open position. This is desirable, since side by side with the trunnions 39 of the other more spring pressure is required in the closed yoke,> and each of these pairs of trunnions is acted upon by spring means which is effective 60 positions of the jaws than in the open positions thereof. to press the jaws against the channels 4I, and In using my improved sock stretcher, the sock when the jaws are open, to hold them open. is first slipped over the foot member I2 andÁ the Merely as an example of one form in which such leg portion of the sock is drawn up over the spring arrangement may be embodied, I have shown in Figs.
