the point Where bending is to take place,

3. A scale on which variations from the correct angular bending of the head and anytwisting ofthe head may be detected in mag nified proportions, this scale comprismgz (a) indicating means on the free end of the bending lever.

(1)) scale members rlgldly connected tothe clamping means.

In the illustrated form of the invention, there is a circular scale fixed to the clamping means and a pointer mounted ona cross member secured to the direction member at a right angle thereto, the cross member lying in the plane of movement of the direction member. The pointer shows by its displacement'on the scale the angular displacement of the direc-V tion member, and the cross member indicates by its angular displacement from the plane of the scale any twist which may have been imparted to the type lever.

In the drawings, which show one form of the invention:

Fig. 1 is a cross section of the device on the line 11'of Fig. 2; I

Fig. 2 is a top plan view of the device. In the form shown, a base plate is provided with two lugs a, a, a raised portion a,

and a scale I). In one of the lugs a the ten-i sioning member 0) is slidably but non-rotatably mounted. The member '1) can be moved bythe screw M which is turned by handle 25.

A cylindrical member to fits tightly in the other lug a. A pin a: is secured in one end of member to and extends into a longitudinal bore in member 0. Sn the second lugare mounted a pin Z and" an eccentric disc m mounted on a shaft n andoperated by a handle 0; 1

On the blocksg slidable in undercut grooves 29. The

blocks are provided withupward extensions 1 substantially triangularin cross section.

The straight verticaledges c of the upward extension r form bendmg ec ges upon which the. type lever 1s bent.

Before clamping thetype lever f into posi-' greater than the width of the type .lever. The rear end of thetype lever is now placed. between members h) and w in sucha way that the'hook rests onthe pin 00 as shown in Fig; 1.

The body of the lever now lies between pin Z and eccentric m and between the two upward raised portion 2 are mounted two extensions r. The members '2) and w are' now ,moved towards each other, but'are not tightly clamped, so that lever f may still pivot around pin Handle 0 isthen operatedto turn eccentric we so that it will clamp the lever tightly against the pin Z. Members '22 and w are'now clamped tightlytogether to hold the typelever firmly in place. Themembers' v and w, the pin Z and eccen mam, and the extensions?" on blocks'gfall mounted on the'based',serve to'hold the lever against movement, and as these holding means extend up to the portion be bent, the lever must always bendat theproper point.

i The 'bjending lever orjextension member 6 f its-now.clainpedtightly to the portion ot lever f is to be'bent. I This is accomplished by a clamp member 9 a nut and bolt 2 and an eccentric lever 9 operating on clamp member 9 topress it against oneend g of extensionniember c to clamp the head of the-- typelever tightly therebetween. The end of the extensionmember is provided with a S i ly shaped recess in which the head. of the type :lever' fits. 7. i

The typelevers'are' placed in the clamps and the extension member may be turned by any desirable amount to give the proper angle to the lever f.

Means are supplied for indicating the bending of the lever and for detecting any twist in the lever such as sometimes occurs during bending. On the base plate (1 is a horizontal semicircular scale I) with scale divisions marked thereon. On the extension member 6 is a cross member 2' substantially perpendicular to the member e and closely adjoining the scale 1) and curved similarly to the scale 6. This, as shown in Fig. 1, is normally in the plane of the scale 6. On this cross member is a pointer k to indicate the various scale divisions. The scale divisions are preferably so arranged that the pointer points to scale division 0 when the extension member is clamped to a straight type lever. On the end of the extension member is a han- 1dleh for manipulation of the extension mem- In the present form there are twenty-two scale divisions on each side of the zero point, so that forty-five different bendings of the head of the type lever are permitted. If the point 10 is chosen for the final bending angle of any lever, the lever is bent until pointer 70 is slightly beyond 10, say at 12, and the lever is then released. The spring of the lever then carries the pointer back to 10, or possibly farther. This bending is repeated until the pointer remains on the scale division 10. The fact that the levers are generally formed of spring steel makes this operation neces sary.

If any twisting of the type lever occurs during bending, the cross member 71 will be bent from the plane of the scale I). This will easily be detected and corrected by twisting the handle it until the twist is removed. The advantage of the device is that errors in the bending and the presence of twist are both shown on an enlarged scale. Also, the bend ing lever is perfectly free to move, and the type lever will have the same sh ape to which it has been set after it is removed from the device. In addition, the correctness of the set may be udged at once without removing the type lever from the device, and any errors may be corrected.

While I have described herein one embodiment of my invention, I wish it to be understood that I do not intend to limit myself thereby except within the scope of the appended claims.

I claim:

1. A device for bending type levers comprising means extending up to the portion to be bent for holding said lever against movement, an extension member adapted to be secured to the portion to be bent, and cooperating means on said extension and on said holding means for indicating the bending and twisting of said lever.

2. A device as claimed in claim 1, said insignature.

HANS LUCIE.
