SPECIFICATION forming part of Letters Patent No. 605,328, dated June '7, 1898. Application filed July 2, 1897- Serial No. 643,272. (No model.)

To aZZ whom it may concern: terior contour of the head B, upon which it Be it known that I, JOHN F. MGNUTT, of is designedto fit,so as to be capable of verlVarren, in the county of Trumbull and State tical adjustment.

The skilled in the art to which it appertains to block is rendered adjustable as against the 60 I make and use the same. tension of the spring E, so as to increase or This invention contemplates certain new diminish the space between its upper surface and useful improvements in feeders for printand the edge c.

By tightening said screws the envelops, and the like, of various thicknesses, block will be lowered as against the tension one at a time, from the bottom of a pile or of its spring. One screw may be adjusted stack thereof. The feeder can be adjusted more than the other when it is desired to ob- 7o both vertically and laterally to accommodate tain a greater distance between the surface itself to any unevenness or irregularity in the of the block and the edge of the head at one pile or stack. end than at the "other. 5 This is rendered The invention will be hereinafter fully set necessary in feeding uneven stock, such as forth, and particularly pointed out in the envelops.

is a groove or cutout conforming to the exfree to move axially thereon to conform to any irregularity in the stock. Thus not only will the feeder as an entirety conform to the irregularities in the pile of stock, but any unevenness in the articles composing the pile can be compensated for by the greater or less adjustment of one side of the block.

While I do not restrict myself to any special means for operating the feeder, yet I have shown it in Fig. 1 as being located on a feedtable I, the rod a being extended through a hollow guide 75 and adj ustably secured at its outer end to a sleeve carried by a reciproeating carriage 25 I claim as my invention- 1. A feeder comprising a longitudinallymovable rod, a head mounted on said rod so as to move axially thereon, and having an upper, forward edge forminga shoulder, means for adjusting said head perpendicularly to said rod and a block on the forward end of said head having its inner edge adjacent to said shoulder and tapered on its upper surface toward its outer edge, and means for adjusting said block relatively to said shoulder, substantially as set forth.

2. A feeder comprising a longitudinallymovable rod, a head mounted on said rod so as to move axially thereon and having an upper forward edge forming a shoulder, a block on the forward end of said head extended in advance of said shoulder and having its upper surface tapered, a spring interposed between said head and block exerting an upward pressure on the latter, and means for adjusting said block at its sides, substantially as set forth.

3. A feeder. comprising a longitudinallymovable rod, a head mounted on said rod so as to move axially thereon and having a forward edge, means for adjusting said head perpendicularly to said rod, a block on the forward end of said head extended in advance thereof and having its upper surface inclined, and means engaging the sides of said block 'for adjusting and holding the same relative to the forward edge of said head, substantially as set forth. 4;. A feeder comprising alongitudinallymovable rod, a sleeve loose on said rod so as to move axially thereon, a head from which said sleeve extends having an upper forward edge forming a shoulder, a block on said head having an upper inclined surface, said block being extended in advance of said head, a spring interposed between said head and block exerting an upward pressure on the latter, and screws carried by said block at its sides for adjusting said block bodily or at either side, as set forth.

5. A feeder comprising a longitudinallymovable rod, a sleeve loose on said rod and having a bifurcated end, a head adjustably held to said bifurcated end and havinga forward edge forming a shoulder, and a block on said head capable of being raised and lowered thereon, substantially as and for the purpose stated. 1

6. The combination with the rod, of the head mounted on said rod having forward grooved ends and an upper forward edge forming a shoulder,-a block having its upper surface inclined and formed with a longitudinal recess to accommodate said head, a spring between said head and block bearing up? wardly on the latter, and screws carried by said block at its sides and engaging said head, whereby the block may be adjusted bodily or at either side, substantially as set forth.

7. The combination with the rod, of a sleeve swiveled thereon having a bifurcated end, a head havinga lip, and a screw adjustably holding said lip within said bifurcated end, a block fitted on said head so as to be moved up and down thereon, said block having its,upper surface inclined, a spring fitting in a recess of said block and bearing at one end against a shoulderof said head, and screws carried by said block and engaging saidhead for adjusting the former, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

A JOHN F. MCNUTT.
