'Application filed* August 31, 1 922. Serial No. 585376.

To all'whom it may cancer n: e u Be it known; that I, MICHAEL H. Han- ESET, of Syracuse, in the County of Onond'aga, in the State of New York, haveinvented new and useful Improvements inf Shingle Cutters, of which the following, taken in'connection with the acconpanyng drawings,is a full, clear, and iOl. i v i a, i

This invention relates to a portable inachine for 'cutting asbestos shingles and anal-.

exact descrip-` ogous uses 'in which the relatively moving shearing membersand Operating means for "tend through the front faces of the end the movable member, are mounted in opposite hollow heads, or housngs, for gudng and stffenng purposes.

The main object s to provide a sturdy,` ortable device of this character in which;

the various pivotal pins connectingthe relatively movable parts are held against end- Wise displacement by the walls of the end housings, and to utilize said housingsas.

ne'ans for guiding and protecting the movable parts against contact with external ob- `ects.

Another object is to simplify .the construction in such manner as to reduce *to a` minimum the number of pivotal pins reuired for the operation of the movable' s earing member and at the same time to enable the various parts to be easily and v quickly detached' one 4 from 'the other and' reassembled so 'that the various 'parts 'of the entire 'apparatus may be packed into compact space for storage or transportation, ready for' a'ssembling at any time.

Other objects and uses relating to specific.

parts of the device will be brought out in the following description: i i In the drawings: i

As illustrated, this device` comprises a pair of hollow upright end heads laand -l'-, lower and upper connecting bars. -Q and -3- a movable shearng bar -4-, 'and suitab e Operating means for the u guide openings a shearing bar, consisting in thisinstanceof opposite pairs of link levers, and -a connecting bar 6-, having a'n extension -7-, connected toatheshort arm -'8+ of PATENT 5 orri a bell'crank lover which is pivoted' at to the end head If-,and is provided'.

andahetween: the opposite arms of the adleasing the bar -2-' for forward displacement. v i

The bar 2- is somewhat L-shaped cross section, forming an upper longitndinal I rib having its inner face' beveled to form a knife edge -20-- for shearing cooperation with a similarkni'e-.edge -2lon the bari 4.- are of substantially the same width as,

and are guided in the upright chambers --11-- of the brackets -1- and -1'-, the upper'edges thereof being reduced to form lugs --22-- for receiving the lower link arms The shearing edge 21- is formed upon the lower front corner of the bar` l-+5 which is guided in itsvertical movement by the front and rear walls of the chambers llto cause the shearing edge 21 to move in the' vertical plane ofthe shearng edge' 20- of the lower bar -`2-, for

shearing purposes,` the rear side of the 'bar -4- being reinforced by a rib, to reduce the liability of sprngingof the intermediate portion-of the bar during the shearing operation. i

The upper bar -3- is parallel with the lower bar -2- and has its opposte ends bifurcated to 'receive the upper ends of the upper link arms -5-, and are of just sufficient transverse width to fit easily 'between the o'pposite upright walls of the guide chamber -11--, and are Secured to said side walls by bolts 23 which are also passed throughregistering apertures in the adj acent upper-'ends of the link arms -5- to pivotally connect said' arms to ,the -adjacent ends of thebar -3--and also to the side walls of the brackets -1- and --1'-.

. bar.

That isjthe adjacentends of thelink arms of each .bar are reduced in thickness to overlap one upon the other, and are pivoted to jacent bfurcated end of the bar -6- by a pivotal pin -25-, which is held' against dnced endof thearn 8- of the bell crank lever,' which isipivoted at -9- to and between the' opposite sides of the adjacent bracket --lto Swing Vertically, the chamher --1 1-- of the bracket -1-^- being continued through the upper 'end of said bracket, to allow tree swingng movement of the bell crank lever in the operation of the connecting bar 6- and link arms -5- for raising and lowering the movable shearng bar -'-4-.

The longer-arm, or handle -10-, of the bell crank lever, extends above the upper end of the adjacent bracket -1-, to overhang the intermediate portionof the device, with sufiicient clearance to allow 'it to be moved vertically'the necessary distance to' open and close the 'movable .shearing bar The shorter bar *8- of the bell crank lever, is connected 'to the bifurcated extension -7- by means of a pivotal pin -26- which is held against endwise displacement by the side v walls of the bracket 1- p e It'will be observed that the adjacent ends -of each pair of link arms is connected to the bar -6- by a single pivot, and that all of the movablepivots, as 24L-- -25- and 126- are held against endwise displaccment solely' by the side walls of the brackets -land 1'- without extra 'astening means such as nuts, cotter keys and' analogous devices.

By renoving the bolts -19- and -19'-, and 'braces '-`-17-, the lower bar -2- may be -readily wthdrawn forwardly through the front,- open side of the branch chambers -12-, in case it should become necessary to sharpenvthe c'utting edge -20- or for any other purposes lili@ By removing the pivotal bolts -9- and 23 the brackets --1-- and -l'-.may be removed, thus permitting the upper bar -3-, shearing bar 4- and its Operating means, including the bar -6-, link levers -5- and bell crank lever to be detached by simply removing the

pivotal bolts

24, 25 and 26, which allows the various disassembled parts*to bepacked 'in compact space, for storage or transportation, and also allows the shearing bar t-a to be reslarpened and other repairs to be made if necessary.

The upper bar 3- is provided with shoulders -30- for engaging the inner edges of the upper portions of the brackets -1 and -1'- to assist in holding the latter in fixed spaced relation and thereby to stifien the device as a whole when the pa'ts are assembled for use.

The movabie shearng bar -4- is provided with guide lugs -31- in sliding engagement with `the inner upright edges of the brackets 1- and -1'- to hold said bar against endwise movement and also to guide it in its Vertical movement.

If desired, one or more thin shins -32- may be inserted between the rear edges of the ends of the bar --2- and rear wall of the brackets 1- and --1'-- to allow for slight adjustment of said bar as may be necessary for proper shearing cooperation with the bar -4-.

`What I claim is:

1. In a shingle cutter, a frame including guide chanbers at the opposite ends therepivotal connections etween said link levers,

Operating bar, Operating level', and mov- -able shearing bar consisting of loose pins which are retained in operative positions by the walls of said guide chambers.

2. In a shingle cutter, a france including hollow upright end heads, a pair of link levers housed within each hollow head, a

movable shearing bar having its encls con-` nected to the link levers within said end heads, an Operating bar connecting said link levers and an operating leVer pvotally connected to one of said hollow heads 'and projectng into the same for pivotal connection with said Operating bar, wherebysaid hollow upright ends will'protect the afoi'e-` mentioned pivotal connections during the operation of the device.

In witness whereof I have hereunto set my hand this th day of August, 1922.
