To all whom it may concem.

Be it known that I, MICHAEL H. FLYNN, a citizen of the United States of America, residing in Hartford, in the county of Hart- 5 ford and State of Connecticut, have invented a certain new and useful Assembling- .Frame for Machines, of which the following is a specification.

In assembling typewriting and other mam chines composed of a number of parts considerable labor is involved in setting and holding such machines in the various positions necessary for such operations. The object of this invention is to provide a holding frame to which the machine to be assembled may be fastened and which is adaptedto be set and retained in various positions, thus permitting free access to all parts of the machines and saving the labor and time of the assembling operator in lifting the machines and holding them in different positions.

In the preferred form'of this invention,

the machine holding frame is axially held.

in a supporting frameon a horizontal line preferably passing through the general center of gravity of the -machine heldby the frame, suitable "stops being provided for determining the principal positions requisite 80 to hold the machine during the assemblage of the'various partsf'of the-same. To fur-...

ther facilitate this work the -supporting frame maybe made to .move about a vertical I heads 'of' bolts IS-and the bottom of a maaxis also, preferably arranged tq pass through the center of-gravity of the machine and in the same vertical plane with the horizontal axis of the swinging frame, or approximately so. I

The dev-ice'in detail will now be described 40 by reference to the accompanying drawings,

inwhich: Y I

Fig. 8, illustrates a modification showing the machine holding bed piece in horizontal position: and 0 Fig. 9, a view at right angles to Fig. 8 showing the bed piece in a vertical position.

The bed piece to which the machine is fastened is rectangular, consisting of

sides

10, 10, and a back 11. The sides have formed in their inner edges recesses 12, arranged to correspond with the location of the supporting feet of the machine to be assembled, which machine is secured to the parts 1.0 by screw bolts 13; said recesses being cut away at their forward ends 14 to afford a free entrance for the heads of the bolts after they are applied to the machine, thus providing for the ready application of the machine to, and its removal from, the bed piece with the bolts loosely screwed in position. This provides for quickly setting the machine on the bed piece and moving it from one assembling frame to another, 'or the bed piecelO, llmay be retained on the machine and'moved with it to'other supporting frames, constructed as hereinafter described. The dotted lines 15 of the drawings represent the main frame of a Royal typewriter, showing the bolts 13 screwed in 35 the holes for the feet of the machine. .The

'17, which constitute the swinging axis of the

bed piece

10, 11, and are so located as to approximately pass through the center of gravity of the machine secured to the bed piece while being assembled. The studs 17 seat in slotted open bearings 18 formed in the tops of the side bars 19of the bed piece supporting frame, said side bars being connected together by a bottom bar 20. At the tops of the arms 16 are extensions 21 so formed and arranged as to contact with the sides of the side bars 19 (as shown at Fig. 7) and thus act as stops to determine the vertical position of the

bed piece

10, 11, and the machine held thereon, for free access to the under side of the machine, as shown at no Fig. 2. The arms 16 may be integral with the side pieces 10, or secured thereto by screws 22, as shown.

The rear edges of the upright bars 19 of the silpporting frames are provided with stops 23, against which the back. edges of the arms 16 rest when the

bed piece

10, 11 is set in horizontal position. These stops 23 may be conveniently formed by notching the bars 19, as at 24, and bending the notched pieces inwardly, as shown at Fig. 5.

The bottom bar 20 of the supporting frame is secured by

screws

26, 26 to a turn table 27 provided with a circular boss or lug 28 fitting in a central hole in the circular base 29, which by means of screws may be conveniently secured to a bench. By this arrangement the bed piece and machine, in whatever position they may be set, may be rotated on a vertical axis and free access had to all parts of the machine. This vertical axis is practically in the same plane with the horizontal axis of the bed piece and substantially passes through the center of gravity of the machine.

A spring 30 adjustably clamped between the central part of bar 20 and turn table 27 has its outer end 31 formed to engage with a notch 32 in the bar 11, whereby the bed piece and machine are held in a vertical position, as shown in Figs. 2 and 3, thus leaving both hands of the operator free to work on the machine while attending to the heavier adjustments thereof.

Different styles of machines may be assembled on this device. For larger machines, or those having a deeper frame, special bed pieces will be used, their arms 16 being longer than those shown, and in such use of the device the spring 30 will be set and held in outer position to engage the bar 11, as shown at Fig. 4, the sharp bend in its base then being at the outer edge of the bar 20 whereas in the other case it is against the inner edge of the bar.

In the modification shown in Figs. 8 and 9, the turn table part is omitted and the supporting

frame

19, 20 is shown secured directly to a bench. In other respects all of the parts may be like the corresponding parts of the device previously described and are similarly designated. The bed piece may in this case be provided with a counterweight 33 to hold the machine in different angular positions.

As the machine which is being assembled and adjusted is supported on an axis passing through its center of gravity it will rest in whatever position it is set and the labor of lifting the machine for such manipulations is avoided and both hands of the operator are free for useful work.
