'SPECIFICATION formingpart of Letters Patent No. 731,267, dated June 16, 1903.

i Application filed December 29, i902. Serial No. 136,879. (-No model.)

To all whom, it' T11/Ly concern,.-

. 3e it known that I, WILLIAM M; BARNES, a citizen of the United States, residing at Philadelphia, county of Philadelphia and State of 5 Pennsylvania, have invented a new and useful Improvement in Ironing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of :o this specification.

My invention relates to certain improve ments in that class of ironing-machines in which the article to be ironed is placed upon a flat ironing-table, which is moved against a hat heated ironing-plate.

I will first describe the embodiment of my invention as illustrated in the accompanying drawings and then specifically point out the invention in the claims.

Figure l is a front elevation of an ironingmachine embodying my invention. Fig. 2 is a plan view on line 2 2, Fig. l. Fig. 3 is a vertical section through toggle mechanism. Fig'. 4 is an enlarged plan view of lockinghandle with table removed. Fig. 5 :is a sectional detail of upright @,bearing b,and arm B.

A is the base of the machine, having the vertical extensions a3 a3. a a 'are uprights secured to these vertical extensions a3 a3.

Sleeved upon each of the uprights a a is the sleeve b for the arm B. The sleeves b are cut away at their central portions, so that the length of contact or bearing of the sleeveb with the upright a is less than the length of the sleeve Z). The ironing-table C is secured to the arm B and is a iiat plate, preferably having upon it a felt or other soft yielding cover. The garment to be ironed is secured upon this tabley at one end by the clamp C and 4o to the roller C2 at the other end. Beneath the ironing-table O and secured to the arm B is Ithe shield c, having the upturned ends c extending beyond the sides of the ironing-table, so as to properly hold and protect any projecting portions of a garment upon the ironing-table. There is one of these arms B sleeved upon each upright a, and each arm carries a corresponding ironing-table.

D is the lower leg, and D the upper leg of 5o a toggle, the two legs being pivoted togetherat el, the lower leg D being pi votally attached to the base A and the upper leg D to a block E.

C3 is a wedge having' the ribbed lower portion e' running on this block and also having the extension c2 surrounding a rod having the threaded end e3 and turning-handle e4. The threaded end e3 of the rod enters the block E. The block E is carried by the cross-bar F, having at its outer ends the rollers f, which rest and travel upon the guides f on the face of the vertical extensions a3 a3.

G is -an internally-threaded block, having the extension g, provided with the vertical slot g', in which slot rests the pin d, forming the pivotal connection of the two legs of the toggle.

H is a shaft having the threaded end h, working in the threadedblock G. This shaft has the bracket-bearings h 71, fromeach side of one of the vertical extensions CL3, and in the spaces between these brackets h and the vertical extension are placed the thrust-bearings h2 h2, preferably having ends formed of 'fibrous material. On the end of this shaft are the loose pulleys I I' and the fast intermediate pulley J, the pulley I being operated by a cross-belt and the pulley I' by a straight belt from a proper source of power.

K is the belt-shifter, having the belt-holders 7c 7c. L is the belt-shifting, rod which is connected to the belt-shifter in the following manner:

l is a block having an orifice in which enters the belt-shifter, the belt-shifter being secured thereto by the set-screw l. The block .has also an orifice in which the end of rod Lena ters and is secured by means of set-screw Z2. By this' arrangement the position of block Z may readily be adjusted. This rod L is pivoted to the link Z3, pivoteu to a projection from ,the bracket h. A

M is a rod connected to link Z3 and passing through a slot in the extension M fromV the block G. Fixed upon the rod M is astop M2.

m is a second rod, secured to the `rod M and passing through an orice m3 in the central 9 portion of upper toggle-leg D and having beyond said central portion the fixed stop m4.

0 is a block on the shifting-rod L, having a rod Z extending therefrom.

a7 is a bracket extending from the vertical roo extension a?, having the rod 2 extending therefrom.

O is a hand-lever pivotally connected to the rods I and 2. Surrounding the rods l and 2 5 are the springs o', contacting with the lever O.

o2 represents nuts on the rods l and 2. By turning the nuts the proper compression to hold the rod from movement by jarring' in any position may be obtained.

Iivoted to the under surface of each arm B is a disk P, having the handle p and the pins 19'132. To the pin p' is connected one end of a coil-spring Q. The other end of the coil-sprin g Q is secured to the fixed pin q, secured to the I 5 arm B. Projecting from the disk P is the hook S. Upon the cross-bar F on each side of the block E is a projection R. 'When either arm, with its carried table, is brought over the toggle-lever to the position shown in Fig. l, zo the handle p of that-table is operated, bringing the hook around the corresponding projection R, where it is held by the spring Q, the pin p limiting` the movement of the handle and disk by striking the arm B. When it is`desired 2 5 to move the table away, the handle p is operated, moving the disk until the pin p2 strikes the arm B, when any further pressure upon the handle will swing the table. Thus this arrangement provides both a locking and moving device for the table.

Fixedly secured to the uprights d a is the cross-frame T, holding central of the machine the ironing-plate T', which is heated in any well-known manner. Secured to this plate so 3 5 as to be in parallel relation with the ironingtable when lifted against the ironin g-plate, as

will hereinafter be described, is the scaleplate V.

The operation o f the machine is as follows:

4o IVhichever ironing-table is to be operated is swung by means of the handle p until the end of the arm B is in line with the wedge. The

straight belt is then thrown on and the screw pulls the block so as to elevate the toggle mechanism, elevating the table against the ironing-plate. When the toggle mechanism rises sufficiently, the extension M strikes the stop fm2, moving the belt onto the idle pulley.

The hand-lever O is operated to bring the cross- 5o belt into action, which moves the screw to bring` the toggle mechanism down, moving the table down from the plate. In the downward movement of the toggle when the toggle-leg D' strikes the stop m4 the cross-belt is shifted 5 5 to the idle pulley. The arrangement of levers and stops is such that in the upward movement of the toggle the shifting of the belt is rapid, while in the downward movement the shift is slower. As may be seen, the exten- 6o sion or stop M is connected to the toggle-leg D at its greatest radial point-that is, the point most remote from its pivot. The stop fm? is also so arranged that the stop or projection M strikes it at the time when the ironingtable is brought against the ironing-plate with the desired pressure. The long radius of the toggle-leg D will thereafter for any movement of the toggle-'leg very rapidly shift the belt. As a consequence the power in the upstroke can bev left on until the very last moment, thus producing the maximum power when ironing upon the ironingplate. In the descent of the toggle, as may be seen, the position of the stopm4 is such that it is struck by the toggle at a point intermediate between its pivot and end. As a consequence, its radial action is much shorter, and consequently a longer period is taken to shift the belt on the downstrcke than on the upstroke. The belt being moved gradually, the adjustment is made so that it is completely shifted as the toggle reaches itsmostv downward position, and the driving-pulley is prevented from having any momentum, which might occur were the shift on this movement made rapidly.

The purpose of having the bearing for sleeve b less than the length of the sleeve is to prevent any spring tendency of the sleeve b causing any binding of the sleeve or bearing.

The purpose of the scale upon the ironingplate, hereinbefore described, is as follows: In order to properly iron the lower ply of an open-bosom shirt at the double-ply portion of the bosom, there has been invented the use of a plate inserted at this point between the folds or plies As bosoms of shirts vary consid erably in length, it often requires considerable time to determine the proper length of plate to be inserted therein. By preliminarily bringing the ironing-table up to the iron ing-plate, the length of bosom, and thus the size of plate required, may readily be determined and the proper plate inserted from a series of plates X, hanging upon pegs at the side of the machine.

So much of the hereinbefore-described machine as comprises the adjustable connection between the belt-shifting rod and the beltshifter and the shifting-lever connected to the belt-shifting rod and its connection and operation I do not claim herein, as the same forms the subject-matter of a divisional application filed by me February l2, 1903, Scrial No. 143,045.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-
