Abstract
Abstract A feeder for a briquetting press comprising a funnel for containing and directing particulate material toward the nip of a pair of cooperating rolls, an elongated ram axially disposed in the funnel with one end extending through the outlet of the funnel, and a power-driven drive shaft disposed normal to the ram and connected to the ram so that rotation of the drive shaft causes axial reciprocation of the ram.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
112 words
A feeder for a briquetting press in which particulate material is compressed in complementary cavities spaced about the peripheries of a pair of cooperating, rotating rolls, said feeder comprising: a. a funnel for directing said particulate material toward the nip of said rolls; b. elongated ram means coaxially disposed in said funnel for compressing said particulate material into the nip of said rolls; c. drive means for reciprocating said ram means in an axial stroke, the rate of reciprocation and the length of stroke being selectively adjustable; and d. means interconnecting said ram means and said drive means for adjustably controlling the pressure exerted by said ram means on said particulate material.
Claim 2
Dependent Claim
112 words
A feeder for a briquetting press in which particulate material is compressed in complementary cavities spaced about the peripheries of a pair of cooperating, rotating rolls, said feeder comprising: a. a funnel for directing said particulate material toward the nip of said rolls; b. elongated ram means coaxially disposed in said funnel for compressing said particulate material into the nip of said rolls; c. drive means for reciprocating said ram means in an axial stroke, the rate of reciprocation and the length of stroke being selectively adjustable; and d. means interconnecting said ram means and said drive means for adjustably controlling the pressure exerted by said ram means on said particulate material.
Claim 3
Dependent Claim
23 words
The feeder of claim 1 wherein said drive means rotates about an axis normal to the axis of reciprocation of said ram means.
Claim 4
Dependent Claim
34 words
The feeder of claim 1 or 2 wherein said pressure controlling means comprises adjustable spring means for translating movement of said drive means into axial movement of said ram means in a compression stroke.
Claim 5
Dependent Claim
129 words
The feeder of claim 3, wherein said ram means comprises a feeder shaft and a flange plate secured to one end of thereof, said spring means comprises a cylindrical sleeve coaxially and slidably disposed around said feeder shaft, one end of said sleeve abutting one side of said flange plate, bolts secured to the one end of said sleeve and slidably projecting through openings in said flange plate, and springs adjustably secured around said bolts and abutting the other side of said flange plate, said springs biasing said sleeve in abutting relationship with said flange plate; and said drive means comprises a power driven shaft and means eccentrically connecting one end of said shaft to said sleeve for translating rotation of said shaft to axial reciprocation of said sleeve.
Claim 6
Dependent Claim
14 words
The feeder as in claim 4 also including means for cooling said feeder shaft.
Claim 7
Dependent Claim
55 words
The feeder as in claim 5 wherein said feeder shaft has a hollow center enclosed at said one end and the other end thereof, and wherein said cooling means comprises liquid conduit means in fluid communication with the hollow center through the one end for circulating cooling liquid into and out of said hollow center.
Claim 8
Dependent Claim
21 words
The feeder as in claim 4 also including a ram plate removably secured to the other end of said feeder shaft.
Claim 9
Dependent Claim
16 words
The feeder as in claim 3 wherein said spring means is disposed outside of said funnel.
