SPECIFICATION forming part of Letters Patent No. 789,448, dated May 9, 1905.

Application filed August 6, 1903. Serial No. 168,538.

To all whom it may concern:

Be it known that I, HENRY PARSONS, of Marlboro, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Beam -Pressers, of which the following is a specification.

This invention relates to that class of machines known as beam-pressers, and has for its object the provision of means for sup porting the die-spindle carriage.

Of the accompanying d rawings, forming a part of this specification, Figure 1, in front elevation, represents a machine constructed Fig. 2 is a cross-sectional view on the line 2 2 of Fig. 1 looking in the direction of the arrow. Fig. 3 is a vertical sectional view on the line 3 3 of Fig. 1 looking in the direction of the arrow. Fig. 4 is an enlarged view of a portion of the mechanism shown in Fig. 3. tional view on the line 5 5 of Fig. 4, showing the tracks for the spindle-carriage:

The same figures of reference indicate the same parts in all the figures.

1 represents the vertical reciprocating beam of the die-press.

2 represents the vertical standards of the framework.

3 represents the front girth.

4 represents the bed-plate adapted for supporting the material to be cut or died out. Rods 5, controlled by hand-wheels 6, are arranged to give the bed-plate any desired position of vertical adjustment.

7 represents a driving-shaft.

The parts above described form no part of my present invention and are here shown for the purpose of illustrating the connection of my invention with machines of this class.

The beam 1 is connected at each end by two rods 10 10 with a power-shaft in such a way (not shown) as to give to the beam 1 any desired reciprocation.

Referring to Figs. 1, 2, 3, 4, and 5, represents a rear girth secured to the standards 2 at the top of the framework. 21 represents a complemental front girth secured to the standards 2 at the front of the machine opposite the girth 20. The girth 20 at its lower end is formed with an inwardly-projecting Fig. 5 is asec-' flange 20, forming a track. The girth 21 is in like manner at its lower end formed with an inwardly-projecting flange 21, constituting a track.

represents a carriage formed at each end with two upwardly-projecting arms 31, each carrying a roller 32. The rollers 32 at the rear of the machine engage the track 21, while the rollers 32 at the front of the machine engage the track 20. By this means the carriage 30 may be moved from one end of the machine to the other. The carriage 30 on itslower side is formed withtwo inwardlyprojecting complemental flanges 36 36, constituting tracks. (See Fig. 8.)

40 represents a spind le-carriage formed with four forwardly-projecting arms 41, each equipped with a roller 42. The rollers 42 at the right side of the spindle-carriage engage the tracks 36, while the rollers 42 at the left side of the spindle-carriage engage the tracks 36. By this arrangement the spindle-carriage can be adjusted back and forth over the work at right angles to the adjustment effected by the carriage 30. The carriage 30 is formed with rollers 37 at its rear end, engaging the under side of the girth 21 in order to steady the carriage.

44 represents a spindle carried by the spindle-carriage. This spindle at its lower end carries a couple of electromagnets 45. The extended cores 46 of these electromagncts support a die 47.

The construction of the spindle-carriage and of the spindle mechanism is claimed by me in another application, serially numbered 168,537, and requires no detailed description in this application.

As the beam 1 rises and falls the spindle 44 will be depressed to force the die 47 through the work.

The described arrangement of the girths 20 and 21 provide highly-ellicient means for applying my improved spindle and spindle-carriage to machines already in the market or for applying said parts to a new machine when for any reason it is not desired to have the carriage supported by the beam.

By the arrangement above described my improved die mechanism can be either applied to new machines or old machines, as desired, and in the latter case this attachment can be made without a reconstruction of the machine.

Having thus explained the nature of my invention and described a way of making and using the same, although without attempting to set forth all of the forms in which it may be made or all the modes of its use, what I claim, and desire to secure by Letters Patent, 1s

In a machine of the class described, two cross-girths one at the front and one at the rear of the machine and connected at their ends to the framework of the machine, complemental HENRY PARSONS.
