1 all whom it may concern:

Be it known that we, JosEPH SALTZMAN and WILLIAM C. Vnrrz, citizens of the United States, residin at Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful improvements in Pressing Machines, of which the following is a specification.

Our invention has reference more particularly to a machine wherein a pressing iron n'iounted for elevational adjustment to and {rem an ironing board or pressing buck and adapted to be manually operated over the top oi the buck to press clothes or other articles on the buck.

Pressing irons, such as are commonly used in tailoring or clothes pressing establishments are quite heavy and it is desirable to employ asupport therefor to facilitate lifting the iron and hold same above the pressing buck and at the same time permit the iron to be manipulated on the buck during the pressing operation with substantially the same freedom as if it were not connected with the supporting means.

T he principal objects of our invention are to provide an improved pressing machine of simple form, which is convenient to operate and whereon the iron is suspendedin such a manner to afford the greatest ease of manipulation during the pressing operation; to carry the support for the iron directly on an elevating spring so as to simplify the construction and facilitate the operation of the machine; to provide an improved means for regulating the elevation of the carrier arm and pressing iron; to provide an enclosedladjnstable mechanism for varying the length oi the carrier arm; to provide an improved pressing buck for a machine of this character: and in general to provide an improved pressing machine which is economical. to manufacture and possesses advantages which have not heretofore been provided. in ma chines of this character.

On the drawings, iis a side view of the pressing machine; Fig. 2 view looking at the front thereof; 3 an enlarged view of the carrier arm, partly in section on the line 33 of 2i an enlarger], sectional view on the line 4.- i of Fig; 1; Fig. a fragmentary view, partly in section of the spring bearing; 6 a top view of the pressing buck.

The supporting frame of this inachlne and Fig.

comprises a pair of spaced standards 1, constructed in a unitary form or otherwise as desired, and having a top 2 mounted thereon. At the rear of the standards 1 and near the bottom thereof is a cross bar 3 having a bearing 4: for the verticalshaft 5 which extends up through the top 2 and is journaled in a bearing ring 6 oscillatably mounted between upright lugs 7, each of which has a cap screw 8 inserted therethrough and en gaging in the ring 6 at diametrically oppo site points. A frame 9 composing a part of the adjustable carrierarm for the iron has a hub portion 10 at" one endtelescoped on to the'upper endof the shaft 5 and held from turning thereon by a pin 11, the ends of which engage in slots 12at opposite sides of the hub 10 so as to permit vertical adjustment of the hub on the shaft 5. A collar 13 is secured on the shaft 5 a short distance below the hub 10 by a pin 14:, and an adjusting screw 15 is threaded through the hub 10 parallel with the shaft?) and engages against the top of the collar 13 so as to faciltate vertical adjustment of the frame 9 on the shaft 5. A set screw'16 is threaded into the hub 10 to lock the frame member 9 on the shaft 5 in the adjusted position.

The frame 9 projects horizontally from the shaft 5 and has an opening 17 extending lengthwise therethrough to accommodate the bar 18, and at the outer end otthe frame 9 and extending below the bar 18 are'spaced cars 19, between which a friction roller 20 is pivoted on a bolt 21 which passed through the ears19.. At the innerend of the frame 9 there is a similar pair of ears 22 extending above the bar 18 with a friction roller 23 pivoted therebetween on the bolt 24 so as to engage the upper edge of the bar, and these rollers 20 and 23 afford an anti-iiriction support enabling the -bar 18 to be easily adjusted lengthwise through the frame 9.

fdecured to the outer end of the bar 18 by rivets 25 or in any other desired manner is an extension 26 havin a bore 27 in alignment with the bar 18. A pin 28 isinserted in. the bore 27 and has an annular groove 29 at the inner end loosely engaged by a screw 30 to retain the pin in the bore 2? and permit pivotal movement thereof. This pin 25 has a ball 31 at the outer end to which a pressing iron is attached, said iron comprising the base 32 and handle 33 which are secured together by the bolt The base 32 has boss on the top with a concave recess in the upper face conforming to and engaging the surface of the ball 31, and the handle of the iron has a depending boss 36 likewise conforming to and engaging the ball. The ball 31 has an opening 37 therethrough somewhat larger than the bolt 34, which latter is secured to the base 32 and projects up through the boss 35 and the aperture 37 of the ball and is threaded into an opening 38 in the boss 36 of the handle. The handle 33 is turned on the bolt 34 so as to loosely engage the ball 31 between the lugs or half bearings 35 and 36 and permit the iron .to swivel on the ball 31, the parts being loclred in such engagement by the lock nut 39 which is threaded in the end of the bolt 34 against the lug 36 of the handle. Thus the pressing iron is not only adapted to tilt forwardly and rearwardly by reason of the pivotal connection of the supporting pin 23 in the bar extension 26, but also has a limited universal movement on the ball 31, enabling the iron to be manipulated in any manner which may be required in the operation of pressing.

A guard 40 consisting of an inverted trough shaped sheet metal cover is placed over the bar 18 and frame 9, and has a cap 41 at one end secured by the pin 42 or in other convenient manner to the inner end of the bar 18, and a cap 43 at the other end secured on the bar extension 26 in any satisfactory manner.

A pressing buck 44 is mounted at the front of the table 2 to support the article of clothing or other material which is to be pressed and in the operation or use of the pressing machine, the iron 32-33 which is normally heldat a slight elevation above the pressing buck 44, is depressed so as to bear upon the pressing buck. For the purpose of sustaining the iron and supporting arm 9*18 in the elevated position and permitting same to be depressed when required, I provide a bearing collar 45 on the shaft 5 at a distance below the top 2 and hold the collar against axial movement on the shaft 5 by a pin 46 passed through the shaftjust above and engaged by the collar. The collar has a ball race in its under face engaged by bearinp; balls 47, which balls also on?" e in a ball race in the upper face of bear 48 loosely encircling the shaft 5 directly below the collar 45. The ring 48 is provided at diametrically opposite sides with loops or eyes 49 or other suitable fasten-ingmeans to which the lower ends of suppcjrti springs 50 are attached, these springs bei b secured at the upper end respectively to the side frames 1 in any suitable manner, as for example, by hooked extremities 51 ring in apertures52 of fin gas of the side frames;

pedalbar 53 is pivoted at its end on a pivot pin 54 between the lugs 55 at the rear 1 assess of the supporting frame and extends out beyond the front of the frame as shown in Fig. 1, terminating in a pedal 56 which is conveniently accessible to the operator when standing in working position at the front of the machine. The forward end of the pedal bar is embraced between a pair of spaced bars 57 which guide the pedal bar, said bars 57 being supported at their upper and lower ends by bolts 58 extending between the side frames 1 and provided with spacing sleeves 59 for holding the bars in an intermediate position between the frames 1. The proper separation of the bars 5'? to accommodate the pedal bar 53 there between may be effected in any convenient manner, as by interposing a short sleeve similar to the sleeves 59 on each bolt 58 between the ends of the bars 57.

A bumper 60 is held between-the bars 55 at their upper ends to bear the impact of the pedal when it is elevated by the lifting tension of the springs 50. This bumper may be clamped between the bars or may be perforated to take the bolt 58 and serve as a separator for the bars 57, if desired. The pedal bar 53, adjacent its rear end extends between the bifurcated extremities 61 of a connector 62 and bears against an insert 63, which is pivoted between the bifurcated ends 61 on the pin 64, the upper surface of the insert being rounded as shown to permit a rocking engagement. The upper end of the connector 62 is of a looped formation with a top cross part 65 having an aperture in which the lower end of the shaft '5 is pivotally secured. The lower end of the shaft is preferably of reduced diameter to afford a shoulder engaging against the top of the cross part 65, and there is a cap screw 66 threaded into the lower end of the shaft 5 against the washer 67, which bears against the end of the shaft and loosely engages under the cross piece 65 to pivotally connect the connector 62 to the lower end of the shaft.

' The pressing buck which hereinbefore been referred to by the reference numeral 44 is of metal and comprises an elongated plate extending transversely of the machine at the front thereof and provided with legs 68 intermediate of. its ends which are secured to the top 2 by bolts 69, and hold the pressing buck or top plate thereof at an elevation above the mach ne top 2. The top plate of the buck has e'nle god rounded ends with a reduced intermediate portion shown in Fig. 6 so that fitted coats or articles of such character may be. laid smoothly on the top plate and said plate is skirted by a depending flange 70 which serves to re inforce thetop plate and protect the gar ments thereon from a gas burner which is placed under the plate. This burner "consists of a pipe 71 extending lengthwise of the buck, midway of its width and closed by end caps 72 which are secured to lugs 73 depending from the top plate of the buck so as to support the pipe at a short distance t-herebelow. A gas supply pipe 74 communicates with the pipe 71 intermediate of its ends as shown inlFig. 2 and the upper surface of the pipe 71 is provided with a plurality of perforations 7 5 so that the pipe 71 serves as a gas burner for heating the top plate of the pressing buck.

In the operation of the machine the gas burner 71 is lighted and controlled so as to heat the top plate of the pressing buck as required and the iron 32 depressed by pressure on the pedal 56 so that the iron may be operated on the garment or other article placed on the pressing buck. The pivotal connection of the iron with the bar 18 through the ball support 31 and pivot 28 and the sliding connection of the bar 18 with the frame 9 and the pivotal mounting of the shaft 5 enables the operator to manipulate the iron by means of the handle 33 over the garment without interference or inconvenience due to the support of the pressing iron.

The mounting of the upper end of the shaft 5 in the swivel bearing 6 avoids binding or cramping of the shaft in the bearing due to the laterally disposed weight on the upper extremity of the shaft and the direct connection of the ball bearing connection 45- 18 with the shaft 5 permits the sha t to swing with ease and respond readily to the elevating position of the springs when pressure on the pedal 56 is released.

The adjustment of the frame 9 on the upper end of the shaft 5 which is effected by the adjusting screw 15 permits the desired elevation of the arm in the operative position to be attained and also the desired cooperating relation between the pedal 56 and supporting arm so that the iron engages the garment on the pressing buck when the pedal is depressed to the desired extent.

While we have shown and described our springs 50 through the invention in a particular form it is to be understood that various changes and modifications may be made without from the principles of our invention, the scope of which is to be determined appended claims. y
