The post l.- is provided with :1 redni-ed top U, through 'whir-h is adapted to he passed :1 eotfer pin 1)" tor sounrel v' lOClilllfI the hearing B in p sihwn on the fixture l3. iv the arrangement descrihod the main frame A, on Witl1(l!il\\'lll the bolt C. can he readily (ll.\('01l110('t'(l from the hearing B, and the lniiezhn Withdrawing the pin D run he readily detached from the permanent fixture l). The holt C and the trun nion A are in. axial nlinenient to. permit of swinging'the nniin fr: me A up or down.

The outer or free ends of the side bars A, A of the main frame A are mounted to turn on iransrersely extending pivots F and nlninly, indicated indig. 1, rhe f xture with wipers H, H adapted to engage the inner and outer faces of the window pane E of the upper or lower sash.

in order to. impart asidewise swinging motion to the outer wiper arm G on im-' parting a sidewise swinging motion to the inner wiper arm G, the following arrangement is made: On the pivots F and F are held forks I, I straddling the wiper arms G, G and being pivotally connected by links I, I with crank arms J, J held on the ends of a transverse crank shaft J journaled in (suitable bearings arranged on the cross bar A of the main frame A. The forks I and I permit of a limited transverse swinging movement of the wiper'arms G, Gwithout disengaging the wiper arms from the forks I and I. It will be noticed that when a 'sidewise swinging motionis given by the operator-to the wiper arm G then a like swinging motion is given to the outer wiper arm G by the connection just described so that both faces'ofthe window pane E are simultaneously wiped or cleaned by the wipers H and H when the window cleaner is in use. The wiperarm.

@window pane PP, the following arrangement is made: On the pivot F intermediate the fork I and the pivotal end of the arm G is arranged a face cam K provided with two ratchet wheels K and K the teeth of which extend in opposite directions as indicated in Fig. 8. The ratchet Wheels K,

side bars A, A of the main frame A adjacent the cross bar A The inner end of the crank shaft L is provided with a crank L under the'control of the operator to permit the latter to turn the crank shaft L with a view to swinging the double pawl K from a normal inactive position, as shown in Fig. 8, into engagement with'either of the ratchet wheels K, K according to the direction in which the handle L? is turned at the time. When the double pawl K enthe ratchet wheel K and a sidewi'se' swinging motion is given to the arms G, G" then the cam K is turned in thedirection of the arrow (1. (see Fig. 8) and when the double pawl K is moved into engagement with the rah-hot wheel K and a swinging motion is given to the wiper arms G, G then the cam K is turned in the inverse direction of the arrow a. From the fore going it will be seen that by the arrangementdescribed the cam K can be turned so as to swing the wiper arm G either toward or from the window pane E with a view to engage the wiper H with more or less force with the outer face of the window pane E,

It is understood that when thefa-ce cam.

K is in the position shown in Fig. 6 the wiper arm G is held in its outermost position, and when the cam K is turned in either position on anr direction as described above then the cam K imparts -,aLn inward swinging motion to" the wiper arirrG to press the arm G with more or'less force in contact with the outer face of the window'pane Eh The wipers H and H are alike in construction and each consists essentially ofa sat metal plate H -to the face ofvwhich issecured a wipingpaid H of a suitable material. with a hearing H in which is mounted a disk N to which is secured'the leaf 0 of a hinge 0 having its other leaf 0 mountedto turn in a pivot 0 held on an angular bracket G forming part of the free end of the corresponding wiper arm G or G. By

the arrangement described each wiper H'is connected by universalsvioi'nt with thecorresponding wiper arm 'allowthepad H to readily assumea 'dsired position on the face of the window pane E to'wipe thesame on imparting a corresponding move ment to the wiper arms G, G, it being understood that the wipers H and H can readily pass into the corners of the window pane to insure a thorough cleaning of the entire faces of the pane (see Fig. 1).

In order to cause the outer wiper arm H to reach the corners or sides of the window The back of each plate H is provided pane it is desirable'to increase the stroke of the wiper arm G relative to the stroke given by the operator to the wiper arm G. For this purpose the throw of the crank arm J relative to the link I is increased by shifting the pivot I in a vertical slot J 3 in the crank arm J by the use of a cam lever P fulcrmned on the outer face of the crank I arm J I p The operation is as follows: In using the device the fixtures D are permanently sethe latter has been cleaned.

cleaner is now in position on the window with the bar A" and the wiper arm G with its wiper H on the inside of the sash, and the bar AS, the wiper arm G and wiper H on the outside of the sash. The operator can now swing the wiper arm G over toward the window pane to engage the wiper H with the inner face of the window pane E and the operator on turning the crank arm L causes an inner swinging of the wiper arm G to engage-the wiper H with the outer face of the window pane E and with the desired force. \Vhen this has been done the operator turns the handle L to move the double pawl K into inactive position so that the wiper H remains in engagement with the outer face of the window pane until The operator now takes hold with the right hand of the wiper arm G and with the left hand of the link I or the bar A to swing the frame up and down and to swing the wiper arm G sidewise to cause the wiper H to wipe the inner face of the pane E As the other wiper arm G and its wiper H are actuated from the wiper arm G it is evident that the outer face of the window pane E is wiped or cleaned by the wiper H. The operator by being able to swing the main frame A up and down and to swing the wiper arms Gr and G sidewise can readily reach every portion of the inner and outer face of the win dow pane with the wipers H and H to evenly clean the same.
