Application filed April. 6, 1999. Serial No. 488,186.

To (.LZZ whom it may concern:

be it known that l, tlonnnms Mnnnnnear, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful improvements in Pad-folders; and it do hereby declare the tollowing 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.

My invention relates to improven'icnts in pad holders, and more particularly to holdttor writing pads, and its object is to provide convenient means for opening the clamp thereof, and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims; referencebeing had to the accompanying drawings, in which:

Figure l is perspective of a device enibodying my invention; Fig. 2 an enlarged plan view of a portion of the sail" e; and, Fig. 3 a side view of the same, still further enlarged and with parts broken away.

Like numbers refer to like parts in all of the figures.

1 represents the board or bed plate of the device. 2 a clamp having lugs 3 turned down and fixed in any convenient manner upon a shaft 4, so as to be nonrotative thereon. Around this shaft is a spring 5 having one end engaging the bed plate, and the other end engaging one of the lugs 3, whereby the clamp is caused to yieldingly grip the pad in the usual manner. This sha l t lis journaled in hangers 10 mounted on the bed plate, and my invention consists n'iainly in the means whereby this clamp may be opened more conveniently than by the usual method of depressing its upper end, for which purpose the shaft 4 is prolonged. to a point near the corner of the bed plate and thence bent rea Hard as at 6 forming a. crank arm and thence extended upward as at G terminating in a push button 7 to manually depress the arnnand thus rotate the shaft and open up the clamp member 2. The crank member is inclosed in a casing 8 having a, recess 9 to receive and journal the shaft, and also provided with an opening 11, through which the upwardly extended portion 6 extends. This case is also provided with lugs 12 wiereby it is attached to the plate 1 and has a projection with which the fingers ot' the operator are engaged when the push button 7 is depressed by the thumb. Beneath the crank arm 6 i. 2 spring 14. within the case which tends to raise the crank arm and thus assist in yieldingly closing the clamp 2 upon the 1 ad.

that I claim is:

1. A pad holder comprising a bed plate, hangers mounted on the bed plate, a. shaft journaled in the hangers and extended to near the side of the bed. plate, a clamp meml'ier supported on. the shaft by lugs non-rotative on the shaft, a crank arm on theend of the shaft, and extended rearward and thence upward, a casing having a recess to receive the crank arm and an opening through which the upward extension project-s, a push button on said extension, and a spring to yieldingly force the clamp member toward the bed plate.

*2. A pad holder, comprising a bed plate, a shaft journaled in hangers mounted on the bed plate, a clamp member mounted on the shaft. and rotative therewith, a spring to yielding-l force the clamp member toward the bed plate, a crank member extending rearward from one end or the shaft, an upvard extension on the crank member, a case inclosing the crank member and having an opening through which the said extension projects, and a rearward projection on the case.

In testimony whereof I atlix my signature in presence of two witnesses.

CORNELTS ll IEDENDORP.
