1 Claim.

This invention relates to the. jumper typ of pressing machines used in the pressing of various parts of garments during the process of. manufacturing and has for one, of its objects the pro- .5 vision of a machine of this character which will develop the maximum amount of pressure with a minimum amount of exertion by the operator.

Another object of the invention is to produce a machine of this nature in which the pressing iron carrying means may b angularly adjusted with respect to the pressing buck, the said machine being provided with further novel means for adjusting the distance between the pressing iron and the said buck.

Another object is to produce a device of the character described in which the maximum simplicity of construction and operation is secured.

Other Objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described, and illustrated in the accompanying drawings, wherein similar reference characters are used to describe corresponding parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claim.

The disclosure made the basis of exemplifying the present inventive concept suggests a practical embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to be under: stood from an illustrative, rather than a restrictive standpoint.

The inventive idea involved is capable of rec'eiving a variety of mechanical expressions, one

of which, for the purpose of illustration, is shown in the accompanying drawings, in which Figure 1 is a perspective view of my improved pressing machine looking from one side thereof.

Figure 2 is a side view thereof, partly in section looking from the front of Figure 1.

Figure 3 is a sectional plan view taken on line 33 Figure 2, and

Figure 4 is a fragmental sectional View taken on line 4-4 Figure 2.

Referring now to the drawings in detail 5 indicates a frame or base upon which is supported a table 5 to the front of which there is secured a pressing buck l. The upper rear end of the frame 5 is provided with a pair of brackets 8 terminating in hubs or bosses 9 in which there is secured a shaft l9 pivotally supporting a lever I I. The said lever i I is provided at the upper front portion thereof with a pair of bearings 12 and I3 (c1. sir-#9) in which there is iournalled an upright shaft or pin E5 to which there is secured by a set screw l6 (see Fig. 4,), a carrier arm ll provided. with a slideway E8 slidably supporting a slide bar l9, the front end of which suitably supports the pressing 5 ir0n20.-' ,o

Agbell crank lever 2! is pivotally mounted below the table 6 on a pin 22 journalled in ears 23 extending from the rear of the frame 5 and is providedwi-th a short armM and a long arm 25. The short arm 24. is connected by means of a, bifurcated link 26 to the lower extremity 21 of the lever II and the long arm 25 is connected by means of a rod 28 to a foot lever 29 pivotally mounted at 30. The said rod is provided at one end with a right hand thread and at its opposite end with a left hand thread, one of the said ends being threaded into a yoke 3i depending from the lever arm 25 and the other end into a cross pin 32 in the foot lever 29. The above referred to connec- 20 tion provides means for swinging the lever H about its pivot l9 and adjusting the angular position of the pressing iron carrier with respect to the buck I.

For adjusting the vertical distance between the I ironZfi and the buck I and thus regulating the pressure upon the material being pressed, I provide a threaded rod or screw 35 which is screw threadedly supported in a plate 36 and is provided at its lower end with an enlargement or disc 31 which is adapted to engage a boss 38 on the foot lever 29. By screwing the rod 35 downwardly, the iron 29 is brought into closer proximity to the buck l and by unscrewing same, the iron is drawn away from the said buck, thus providing adjustment for the accommodation of various thicknesses of material and simultaneously providing pressure adjustment upon a given thickness of material.

The foot lever 29 may be releasably locked in a given position by means of a pawl, pedal or auxiliary foot lever 49 pivotally mounted at 4| on the foot lever 29 and in engagement with a pair of a series of teeth 42 cut in strips 43 secured to the front of the frame 5. A spring maintains the auxiliary foot lever in engagement with the teeth 42. I

The foot lever 29 is maintained in and returned to its normal upper position by means of a pair of helical springs 45 exerting a pressure, between the rear wall of the frame 5 and the heads 46 of studs or rods 41 which pass through the said rear wall and the lever l I, and the said rods maintained in the said lever by means of nuts .8 on the screw threaded ends of the said rods. The pressure of the said springs 45 may be regulated by loosening or tightening the said nuts 48.

It will be seen by referring to Fig. 2 that the springs 45 are quite heavy and exert a considerable pressure or tension upon the foot lever 28,

yet due to the location of the said springs with respect to the fulcrum l0 and the relation of the bell crank lever 2| to the lever H and foot lever 29 and the relative position of their fulcrums, but a very slight exertion on the said foot lever will overcome the resistance of the said springs, thus enabling a person of moderate or even very little strength to easily operate the foot lever. In other words but a slight contraction of the springs 45 will be necessary to operate the foot lever to depress the iron against the buck.

It is also to be understood that besides operating the machine for pressure pressing, it may also be used for hand pressing, that is, the iron may be drawn across the surface of a garment. To accomplish this, the carrier I1 is actuated to move or swing with its pivot 15 to which it is secured. In order that this movement is easily accomplished, I provide an end thrust bearing comprising a pair of hardened semi globular or plano-convex discs or members 50 in the bearing [3 at the bottom of the shaft or pin l5. Instead of using two such discs only one may be used and the bottom end of the pin l5 may be rounded and hardened and allowed to contact the lower disc 50.

From the foregoing, it will be seen that I have provided a simple yet efiicient pressing machine which is easily operated and which is considerably less expensive to manufacture than other similar pressing machines now on the market.

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

In a pressing machine, a frame having front and rear walls, a bearing bracket carried by the rear wall, a lever pivoted to said bracket by a horizontal pivot and extending vertically with its lower end below the bracket, iron supporting means carried by the upper end of said lever, a bell crank lever pivoted to the rear wall and having a long arm extending horizontally towards the front of the frame and a short depending arm at the rear end of the long arm, a link connecting the lower end of the short arm to the lower end of the first lever, a rod extending through the rear wall above the bell crank lever and having a head at its front end and a threaded rear end portion engaged through an opening formed in the lower portion of the first lever, an adjusting nut on said rod bearing against the rear of the lever, a spring about said rod between its head and the rear wall to yieldably resist movement of the first lever out of a normal position, a treadle pivoted to the rear wall and extending forwardly under the bell crank lever, and a link connecting said treadle with the long arm of the bell crank lever.
