JOHN HARTMAN, or MORRAL, OHIO.

BOLT-RETAINER.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed July 2. 1906. Serial No. 324,315.

To all whom it may concern:

Be it known that I, JOHN HARTMAN, a citizen of the United States, residing at Morral,

in the county of Marion and State of Ohio,

have invented certain new and useful Imrovements in Bolt-Retainers; and I do'herey declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide means for holding or retaining bolts from r0- tation while the nuts are being turned up on them. 1

The invention consists in the construction hereinafter described and claimed, the in.- vention not being confined in its embodiment to the particular forms and proportions of parts illustrated in the accompanying drawings.

In said. drawings, Figure 1 is a view in elevation of the outer side of the device. Fig. 2 is an edge view, partly in section, illustrat ing how the device is used. Fig. 3 is a transverse section on the line 90 at, Fig. 1, looking to the right. Fig. 4 is a side view of one of the retainers, showing how it is adapted to a bolt having a head of larger size than that illustrated in Fig. 1..

As each side of the retaining device is the symmetrical duplicate of the other, a description of one will suffice for both.

In the views, 1 designates the retainerframe. This frame is of rectangular form with a rectangular opening and. is .rovided in one side of the opening with a series of flat bars 2, placed side by side and pivoted upon a common bolt 3, secured transversely in one end of the opening. The free ends of these bars. 2 are slightly beveled, and they fit against a beveled surface or seat 1 in the end of the retainer-frame. This seat prevents the bars from swinging beyond the opposite side of the frame. The retainerframe is also provided with a plate 4, having a handle 43, secured on raised portions 1. at the end of the retainer-frame.

Connecting the two retainer-frames is a v bar 5, having a sto 5 at its middle and stops 5 at its ends. T e retainer-frames are adjustable on the bar 5, and the stops 5 prevent the removal of the retainer-frames from the bar. The stop 5 limits the movement of the retainer-frames toward each other and insures a centering and compacting of the frames on the bar when the device is not in use.

In practice the retainer-frames are placed on the heads of two bolts that are to be secured, as many of the bars 2 being turned up as may be necessary to provide a sufiicient o ening to permit the frame to be placed on t e bolt-heads, and yet prevent the bolts from turning therein, after which the nuts can be turred up as tightly as desired. The fact that the device is engaged with two bolts of course prevents it from being turned with the bolt.

In Figs. 1, 2, and 3 one only of the bars 2 is turned up; but in Fig. 4 five of them are turned up, because the bolt-head therein shown is of greatly larger size. With this construction the device is not only adapted to bolts that be placed at various distances apart, but it is also ada ted within limits to bolt-heads of many di 'erent sizes.

What I claim, and desire to secure by Letters Patent, is

1. A bolt-retainer comprising, in combination, a pair of retainer-frames having openings therein, a series of bars pivoted in said frames, and means connecting said frames whereby they are adjustable with respect to each other.

2-. A bolt-retainer comprising, in combination, a pair of retainer-frames having openings therein, a series of bars pivoted in said frames, handles on said frames, and means connecting said frames whereby they are adjustable with respect to each other.

A boltretainer comprising, in combination, a pair of retainer-frames having openings therein, a series of bars pivoted in said frames, a bar connecting said frames whereby they are adjustable with respect to each other, said bar having stops to prevent the removal of the frames therefrom.

4. Abolt-retainer comprising, in combinaprevent the removal of the frames theretion, a pair of retainer-frames having openfrom.

To ings therein, a series of bars pivoted to said In testimony whereof I afllx my signature frames, a bar connecting said frames and on in presence of two witnesses.

5 which they are adjustable with reference to JOHN HARlMAN each other, said bar having a stop to limit the Witnesses: inward movement of the frames thereon, and SAMUEL E. MORRAL said bar also having st-ops near its ends to W, W. MORRAL.
