a Claims. (01-. *236) This: invention relates to cleaning and scraping implements and particularly to an improved device for removing ice and other substances from surfaces such as the Windshields of. motor vehicles, sidewalks, roadways and the like.
An important object of this invention is to provide an improved eflicient scraping and cleaning device. for quickly and conveniently removing ice, hardened SHOW and other foreign substances from-surfaces such as motor vehicles Windshields, sidewalks, steps and, roadways. Another important object of this invention is to provide an improvedv cleaning and scraping implement embodying parts designed in a novel manner for manufacture. and assembly-at low cost. Another important object of the invention is to :provide a device of this character which is rugged and durable. and which may have associated there.- with certain novel features renderin the device usable for other cleaning operations. A further importantobject of the invention is to provide an'ice scraper including novel cutting teeth having a limited universal movement so as to predispose their-cutting edges in any direction in which the implement is used and which teeth are also permitted a limited angularmovement relative to the implement. A still further important obiect of thexinvention isto provide a novel mount- "ing" for the teeth, which mounting is adapted to apply a point bearing contact on. the teeth. when the implement is pressed into engagement with a surface to be cleaned in order that the teeth may rotate and incline freely in use. a
' In carrying out the invention, one embodiment of the invention is of relatively small size adapted tobe held in the hand ofthe operator and for such construction it is preferably composed entirely of plastic material. A plurality'of'teeth or pins are: mounted in the body of the implementand arranged. to project from the bottom side thereof; Thesepins are loosely mounted in the body for limited universal movement bot-h rotationally and in-clinably relative to the body and are providedfwithcutting edges on their projecting ends 7 which are capable of adjusting themselves for teeth or pins for cutting and: scraping solid layers V of ice.
This invention constitutes an improvement to that described and claimed in my copending. application for United States, patent Serial No. 747,181,. now Patent No. 2,556,691, dated June 12. 1951.
Various other objects, advantage and men.- torious features will becomemore fully apparent from the following specification, claims, and. accompanying drawings wherein;

The various embodiments of the invention illustrated in the drawings are adapted to be held in the hand of the user and applied over an ice coated surface such as the windshield of a motor vehicle. For such use, it is preferred to make the devices substantial-1y wholly out of plastic material. The invention, however, is applicable to larger scraping and cleaning implements such as for removing ice from roadways and sidewalks.
Referring to Figs. 1 to 4 inclusive, this particular embodiment of the invention comprises a body portion generally indicated at Hi. This body portion is of a. size and shape to be con,- veniently and firmly grasped in the palm of the app nded the sidewalls thereof.

hand and'for this purpose it is made non-circular in formation, being provided with a plurality of flat sides [2 forming a polygonal or oxtagon shape as shown in Fig. 1. For convenience in manufacture and assembly the body It is preferably composed of two superimposed plates or blocks [4 and IS of plastic material. One plate. such as the plate I4, forms the upper portion of the body and as shown in Fig. 1 is preferably of the polygonal formation previously described. The upper surface of the top plate 14 is recessed as at If! throughout substantially its entire area except for the margins thereof to form a depression for the purpose to be described hereinafter. The bottom plate member as shown in Fig. 1 is preferably of circular formation having a diameter slightly less than the transverse dimension of the upper member and centrally located thereagainst so that the fiat sides I2 of the upper member project beyond the periphcry of the lower member.

The lower body portion [6 is shaped to form in combination with the upper member 14 an inner cavity or compartment occupying substantia lly the entire area of the portion except for This compartment as indicated at 20 in Figs. 2 and 3 and is completely enclosed except for the provision of the passages -or apertures 22 in the bottom side 23 of the body portion [6. The passages 22 cover a large area of the bottom side of the body l0 and are preferably arranged in symmetrical order as shown in Fig. l.
Mounted in the bod I!) and projecting through the passages 22 are a plurality of ice cutting elements or teeth. These cutting elements correspond in size and shape to one another and are preferably composed entirely of plastic material or material less resistant than the surface upon .cross section as shown in Fig. t. At the June-- 'ture of the shank portion 24 to the head portion 26, each pin is preferably provided with a circu- Both the shoulder 28 and the shank portion 24 have a cross sectional dimension such that they are freely received within the passages 22 of the base portion l6 of the de- The relationship of the passage to the shank portions of the pins is such that the latter are capable of freely rotating in the passages and of inclining thereto in the manner illus trated in Fig. 3.
Each head 26 of the cutting element or pin is preferably cylindrical in formation as shown in Fig. 4 and the diameter of this head is construct- .pin is retained within the body against removal therefrom.
Each head 25 of the cutting element of the pin is further provided with a recess 30 opening out through the upper end of the head. The recess .circular paths.
3a is preferably conical in formation, reducing in lateral extent as the bottom is approached and terminating in a narrow base 32 which is slightly rounded as shown in Figs. 2 and 3. When mounted in the cavity or compartment of the body, the axial length of the heads 26 of the cutting pins is less than the height of the compartment as shown in Fig. 2.
The top plate portion M of the body I0 is provided, preferably at its time of manufacture, with a plurality of downwardly extending projections 34 corresponding in number to the number of pins and apertures in body and arranged in line with the axes of the passages 22. These projections 34 are each preferably of conical formations as shown in Figs. 2 and 3 reducing in lateral extent as they approach their lower extremities. The bottom ends of the projections 34 are preferably rounded and provided with a curvature corresponding approximately with that of the bases 32 of recesses 30. The length-of the projections 34 are such that when the heads 26 rest on the bottom side 23 of the base plate IS the terminating ends of the projections are spaced from the bases 32 of the recesses 30. However, when the device is applied to an ice coated surface, such as the glass windshield 36 shown in Fig. 3 and the pins are pressed against the ice coating 38 thereon, the pins are elevated in the compartment 20 bringing the terminating ends of the projections 34 into contact with the bases 32 of the recessed heads. In this manner a point bearing contact is formed between the projections and the heads, the former taking the axial thrust of the pins but at the same time freely permitting rotational and inclinable movement of the pins in the manner shown in Fig. 3. The conical sides of the recesses 30 and the projections 34 are so related that they gov ern the maximum inclination of the pins relative to the axes of the passages through which they extend. As shown in Fig. 2, the recesses 30 are made in oversize relation to the projections 34 and have their conical walls extending at a greater angle than the conical surfaces of the projections. At the maximum inclination of each pin, as shown in Fig. 3, the conical wall of the recess 39 of each pin facially abuts a side portion of the entering projection and is rigidly held by the latter from further tilting movement. As a result of this construction, the pins are free to rotatably adjust themselves and to assume the desired inclination as the device is pressed against an ice coated surface and initially advanced in one direction thereover. The point contact provided between the ends of the projections 34 and the bases 32 of the recesses enables the pins in the initial movement of the device over an ice covered surface to rotatably adjust themselves so that they present one of the flat faces of the pin shanks perpendicular to the direction of sliding movement. The lower end of each shank thus presents a cutting edge transverse to the direction of movement and regardless of whether the movement is in straight or The user therefore may apply circular or arcuate movements to the device as it is scraped over an icy surface and the pins will self adjust themselvesto present a straight cutting edge extending substantially perpendicular to the direction of movement of the device at any given point of its travel.
After the ice on an ice coated surface has been loosened, the device may be inverted bringing its top portion into contact with the surface.

An ice scraping implement comprising, in combination, a hollowed body having a plurality of correspondingly shaped parallel passages opening at one end out on one side of the body and at the other end into the hollow interior of the body, a plurality of correspondingly shaped pins each having a shank portion and a relatively wide head on one end of the shank portion, said pins each being mounted in the body with the shank portion thereof extending through one of said passages and projecting beyond said side of the body and having the head thereof disposed in the hollow interior of the body to lock the pin within the body against withdrawal, the shank portion of each pin being substantially uniform in cross section throughout its length and being less in cross section than that of the passage suficiently to provide a maximum angular movement of the pins in any direction relative to the body of approximately 12 degress to the axis of its respective passage, said heads of the pins each provide with a conical shaped recess opening out from the side thereof opposite to the shank portion of the pin, and a conical shaped projection in the body for each pin entering said recess thereof and adapted to have its outer extremity engage the bottom of the recess to provide a point bearing contact therewith to take the thrust of the pin. 5. An ice remover comprising, in combination, a body of a size to fit within the palm of the hands with the fingers thereof engaging the sides of the body, said body provided with a plurality of passages each opening out through the underside of the body and terminating at the other end within the body in a cavity of greater cross sectional area than the passage, a pin in each passage having a head portion of greater cross section than the passage disposed within the cavity for locking the pin against removal from the passage, the head of each pin provided with a conical shaped recess opening into the cavity on the side thereof opposite to the passage through which the pin extends, and a projection forming part of the body for each pin entering said recess and adapted to engage the bottom thereof to provide a point bearing contact for taking the thrust of the pin when the projecting end thereof is pressed against an ice coated sur-' face.
6. An ice removing implement comprising, in combination, a body of a size to fit within the palm of a hand and having substantially parallel top and bottom surfaces, said body provided with a plurality of correspondingly shaped parallel passages each opening at one end out through the bottom surface of the body and terminating at the other end in an enlarged cavity within the body, a pin for each passage having a shank portion of greater length than the passage and a head portion oversize the passage, each pin being mounted in the body with the shank portion'exte'nding through the passage and projecting beyond the bottom side of the body and with the head portion disposed within the cavity so as to prevent withdrawal from the pin from the body, the shank portionof each pin being less in cross section than the passage in which it is mounted so as to provide clearance for limiting angular movement of the pin in any direction relative to the body, the head portion of each pin being provided with a conical shaped recess opening upwardly in the direction of the top surface of the body, and a downwardly depending projection in the cavity opposite each passage forming part of the body and entering the recess of the head portion of the pin in the passage opposite which it is disposed, said projections each having a length greater than the depth of conical recess in which it enters and adapted to engage the bottom of the recess to take the axial thrust of the pin when the projecting end of the shank portion is pressed against a surface.
