My invention relates to pressing machines and more particularly to head elements and buck elements employed therein.

' The principal object of the invention is to provide either a head element or a buck element. or both. capable of simultaneously ironing the top and sides or sleeves and the like. To carry out this object, it is the further object of my invention to provide ilexibility in one or both of said elements, which will permit such element or elements to ilex upon engagement with each other and exert pressure against the sides as well as the top of the garment being pressed.

Another object of my invention is to provide means for holding an end of the garment while adjacent portionsare being ironed. Still another object is to provide means to prevent such ilexible elements from pinching or leaving a crease upon a garment.

My invention also has for its object to provide such means and elements that -are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple and of general superiority and serviceability.

The invention also comprises novel details of ,construction and novel combinations and arrangements oi parts, which will more fully appear in the course of the following description. However, the drawings merely show and the following description merely describes one embodiment of the present invention, which is given by way of illustration or example only.

In the drawings, like reference characters designate similar parts in the several views.

Figure 14 is a perspective view of a head comprised in said modiiied construction.

Figure 15 is a perspective view of a buck comprised in said modified construction.

Referring more in detail to the drawings, the reference number I2, in Figure l, generally designates a frame of a pressing machine having a buck I 3 supported by a goose-neck 9 I. The end of the buck I3 is of reduced size, as shown at I4. The buck carries padding I5.

A pressing arm IS on the pressing machine carries a cross plate I1. The pressing head includes two members I8 and I9 provided with hinge knuckles 29 and 2I on member I9, and hinge knuckle 22 on member I 8. Suitable hinge pins 23 are inserted in the knuckles 20 and 22 to articulate the head members I8 and I9. Steam chests 24 and 25 are respectively mounted on the` outer surfaces of the head members I8 and I9.

Bolts 26 and 21 engage nuts 28 and 29, mounted on the member I9 at the top of the wedge-shaped head 39, which head comprises the members I8 and I9. Springs 3i and 32, respectively coiled around the bolts 26 and 21, urge the nuts 28 and 29, and thereby the head 30, downwardly. Thus when the plate I1 is moved downward by the arm I6, the said plate compresses the springs 3i and 32.

Mounted upon the sloping downwardly extending sides of the head members I8 and I9 are upstanding bosses 33 and 34 which are interiorly threaded. Bolts 35 and 36 are disposed loosely in openings 31 and 38 in the plate I1. When the plate I1 is moved down to a pressing position, it not only compresses the springs 3i and 32, but also bears against the tops of the bosses 33 and 34, thus causing the head members I8 and I9 to swing inwardly toward each other, thus simultaneously pressing the top and sides of any material on the buck I3.

A steam inlet is provided at 39 and a steam outlet at 4D. Similar inlet and outlet are provided for the steam chests 24 and 25. A flexible tubing 4I connects the inlets of the steam chests 24 and y 25 with each other and a exible tubing 98 conjoin, at the ends thereof, and are fastened by nuts |84 on the hinge pins 23. The strip 83 does not interfere with the pressing operation but does prevent creasing and pinching of the buck or material being pressed.

In the modified construction shown in Figure 10, the iiexible connecting tubing 43 is shown as looped at 44 to increase its flexibility. A holding means is provided for holding the end of the sleeve while adjacent portions oi the sleeve are being pressed. This means comprises side plates 45 and 46 hinged to each other at 41. Pads 48 and 49 are provided on the inside oi the plates 45 and 46 respectively, to grip an end of a sleeve on the buck end I4.

Means for pressing the members 45 and 46 toward each other include links 50 and 5| which are respectively pivoted to arms 52 and 53 .on the side plate members 45 and 46. A shaft 54 is carried by an operating arm 55. The shaft is keyed to the arm 55 and to an abutting linger 56, as shown at 51. The finger 56 has a tip 58 that extends under link 50 to prevent the links 50i and from reaching dead-center. A lug 59 on the arm 55 similarly limits link 5I. f

The arm 55 is pivoted at 60 on the frame I2 of the machine. A connecting rod 6| actuates lever arm 55. A pedal 62, pivoted at 63, operatively connects with the connecting rod 6|. Thus the holding means 45 and 46 may be moved to a buck-engaging position to hold the garment in place prior to the descent of the head `to a. pressing position.

In the modication shown in Figures 'I and 8, sideplates 64 and 65 carry on their inner faces pads 66 and 61 respectively. for engaging the padded sides 68 of the buck I4. The side plates 64 and 65 are pivoted to each other at 69. Arms and 1I on the side plates 64 and 65, are urged together by a coil spring 12 which hooks around the arms 10 and 1I, as shown in Figure 8. A stiiening rod 13 maintains the spring 12 in alignment. The rod 13 reciprocates in recesses 14 and in the arms 10 and 1I respectively. v

Actuating means for the holding device shown in Figures '1 and 8, includes a lever arm 16 pivotally mounted at 11 and connected to bolts 18 and 19 on the arms 10 and 1|. Slots 80 and 8| in the lever 16 permits the bolts 18 and 19 to move toward and away from each other laterally during movement of the arms 10 and 1I toward and away from each other.

The lever 16 is operated by a connecting rod 82 in the same manner as the connecting rod 6I and associated parts actuate the lever arm` 55.

In the form shown on Sheet 111.01 the drawings, the head 85 has a fixed cross-sectional shape. A steam chest 86 is provideddfor heating the head 85. Inlet and outlet connections 81 and 88 are provided for the steam chest 86. Arm 89 on the pressing machine, similar to arm/I6, supports the head 85.

The buck, in this form, is the ilexible member. A wedge-shaped core member 90 o! the buck extends laterally from a goose-neck 9|. Recesses 92 in the buck member 90 carry helical springs 93. which in turn support a ridge member 94. Side members 95 and 96 of the flexible buck re- 5 spectively, have alternating fingers 91 and |01 that hook over the ridge member 94I whereby the side members 95 and 96 may swing towards and away from each other. Steam chests 99 and |00 are disposed on the inner faces of the side l0 members'. Inlets |0| and |02 are provided for the steam chests 99 and |00. Suitable outlets (not shown) are also provided.

Padding |09 extends over the buck members 95 and 96 from edge to edge of the buck. A fac- 15 ing material |04 is in turn applied to the padding. The material |04 may also be continuous across the bottom of the buck, to cover same.

However, there should be a looseness in the portion of the material |04 that is under the buck,

2o to permit expansion of the sides of the buck.

In the operation of my device, actuating means for the arm I6 may be any suitable motive means. The actuating means per se forms no part of the present invention.

The arm I6, when lowered, carries the wedgeshaped head down into contact with the padding I5 on the buck. The springs 3| and 32 resiliently urge the head 30 against the top surface of the buck. Further downward movement 30 of the plate |1 causes it to bear against the upper surface of the bosses 33 and 34, which, because oi their position, thereby cause the head members I6 and I9 to swing inwardly toward the buck.

This eects pressing of the material at the sides of the buck. The introduction of steam through the inlet connection 39, and the discharge of condensate through the outlet connection heats the head members.- Conduits 4I and 98 connect the steam chests of the head members 40 with each other, whereby steam is introduced to steam chest 24 through the conduit 4| and condensate is discharged from that steam chest through the conduit 98.

The holding means comprising the side plates a portion of the garment such as a cuff on the reduced end I4 of the buck. The remainder of the garment, such as the sleeve, may then be drawn over the buck, to the left in Figure 1, to eliminate wrinkles. Thereupon the member 30 is lowered into the pressing position as described.

Cushions 46 and 49 (or 66 and 61) engage and rmly hold the portion of the garment contacted by same. 'I'hereupon the lever 55, through the intermediary of the links 50 and 5|, cause the plate members and 46 to move inwardly toward buck I4.

In the form shown in Figures '1 and 8, the vlever 16 presses downward on the arms 10 and 1|, thus causing the side plates 64 and 65 to grip the buck. When the lever 16 is raised the spring 12 draws the side plates 64 and 65 away from the buck. Springs 84 tend to maintain the lever 16 and the ends of the arms 10 and 1I in contact with each other.

In the operation of the form shown in Sheet III, the side members 95 and 96, which are arranged in a wedge-shape, vrest upon the sides of the wedge-shaped buck 90. The garment to be pressed is placed on the material |04 and the head 85 is caused to descend. As the head 85 moves downward, after contact with" the garment. the side members 95 and 96 ride down- 75 ward on the outward flaring, wedge-shaped mem- 45 and 46 (or 64 and 65) is rst lowered to hold.

ber 90, thus swinging the side members outward around the axis of the ridge member 94.

In the forms shown in both Sheet I and Sheet III, the flexible member nrst contacts the other pressing member, substantially at the flexing axis thus pressing the portion of the article on top of the buck, and` then by further pressing invention, the construction is, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not Wish to restrict myself tothe particular form of construction illustrated and described, but desire to avail myself of all modiiications that may fall within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a pressing machine, including a downwardly opening wedge-shaped pressing head and a conformably shaped stationary buck downwardly upon which the head is movable in the pressing operation, said buck consisting of a rigid wedge-shaped core member having upwardly opening recesses spaced therealong, a ridge member, springs seated in said recesses and yieldingly engaging and supporting the ridge member above and along the core member, and side members disposed against the core member and vhaving upper, inwardly-curved extensions movably seated on the ridge member in staggered Vrelation therealong, the rside members being forced to swing laterally by the wedge-shaped core member when pressure of the head on the ridge member forces downward movement of the ridge member.

2. In a pressing machine, lincluding a downwardly opening' wedge-shaped pressing head and a conformably shaped stationary buck downwardly upon which the head is movable in the pressing operation, said buck consisting of a rigid wedge-shaped core member, a ridge mem- `ber vertically yieldingly supported by, and disposed above and along, said core member, and side members disposed atopposite sides of the core member-and having upper hook portions seated on the ridge member, whereby downward pressure of the pressing head on the ridge member causes downward movement and lateral shifting of the side members.

3. A pressing machine including a downwardly movable wedge-shaped pressing head, a stationary goose neck,- a wedge-shaped core member extending rigidly from said goose neck, a pair of side members disposed against the tapering sides of said core member, and a ridge member vertically yieldingly supported by the core member, along and above the same and with which the side members are hingedly in connection along their upper portions, whereby down- `against the tapering sides of the core arm and movably hung at their upper ends on the ridge member.
